Hey guys I am a newbie to app development and I have gotten as far as doing the tip calculator. I am trying to make an intervalometer app based on the ti- calculator app at the link below. Basically, it would use the headphone jack to trigger a camera remote shutter release at a predictable rate for time lapse photography on a Canon DSLR. Here is the TI-83 reference. Any idea how to do this on android. Any help or advice is greatly appreciated.
http://potatoeskillme.com/code/ti-86-intervalometer-for-canon-xti/
Dude, I'm really sorry I'm not skilled enough (yet) to help make this happen.
What a fantastic idea! I would love to see this happen.
Anyone have an idea how to access the audio port in code? I have to close the loop on the headphone jack for an instant and then release it.
You are attacking the wrong hole.
Audio jacks don't behave in the same way as the TI data jack.
Investigate using USB.
I would love to see some sort of wireless control of the camera's basic functions, similar to the hardware wireless control modules for those cameras.
Perhaps easier to accomplish and just as nice would be a way to make the camera a wi-fi storage device for those level Canon cameras. It would be sweet to snap shots to the phone for easy posting to the various places Android supports.
My guess would be that Dalvik (SDK level Code) doesn't have access to hardware level controls.
So this would have to have some Native (NDK Code) in c++ written to make it work. I don't think it would be entirely difficult for someone, but I personally have never tried to use an audio jack for anything other than..well...audio.

Yeah, that was kinda what I was afraid of. I have really bitten off more than I can chew with this project.
How I understand the wired remote works is that it just "shorts" the connection.
Now you may be able to simulate that by sending tones through the left/right and/or both poles. (one focuses the other shoots)
You could probably test if this would work by playing music through the cable and see if the camera reacts. I don't have a 1/8th to 1/16th cable or else I would try it myself because I am interested if it would work.
Here is a link of how to make a remote switch which you might find handy if you pursue this.

Someone mentioned using the usb which would open a whole new world of what you can do. If you have ever played around with the canon software then you know you can control all the camera features from a computer and that should be possible to do on our phones but it would be a lot of work to write an app like that.

USB is the way to go. I've written a few apps for windows that control canon cameras using the canon sdk. Unfortunately, the SDK is all C++, so a wrapper is needed to work with java. Plus there are functions that are windows specific. The other option for Linux is libgphoto2. Unfortunately, documentation is not the greatest (nor is it for csdk).
If I had more time, I would have coded this already. But all my coding time is spent programming for work.

I am going to test your audio idea and see if it shorts the connection. Yeah, I wish I even knew where to begin with working on the USB. I am very new to this. The farthest I have gotten is building a potential layout for the program.
I just looked up some stuff.
I think the canon remote needs a little over 3volts to trigger the shutter. You are not going to be able to get anywhere close to that with the audio output.
I think the only option is to go through the usb.

Thank you for the info. I am downloading the Canon SDK right now(not that I have any idea what to do with it at this point).
is this still going? we are about to make the gsm hero usb-host-mode-able, then all that is missing is libgphoto2 and gphoto2... anyone fancy porting it?
First of all, sorry for my English.
I was searching in Google for something like this and I can't find nothing.
Using the usb is not simple, but the audio option is not crazy at all.
Obviously, that option will require some kind of interface, but can be much simple than the USB option.
You can generate different audio frequencies, for example, 1 KHz for focus and 5 KHz for shutter. With a filter for each frequency you can separate the signal in two circuits. Each circuit can trigger the camera with a transistor, in open collector configuration.
Whatever, if you choose one or another (USB or audio) you will must make some kind of electronic interface.
If someone can works with the software, I can do my part with the circuit. I'm sure that will be easy to build for anyone, even if you don't know electronics.
I am also looking into doing this sort of app, but I am starting with a Pentax k110d... Some camera's only require you to short out the wires, and doing so with the audio headphone jack seems to be possible, from the quick little test I just did with a media player, a 3.5mm jack extension cord, and a multimeter. When the track was playing, i got some resistance across the poles, but when I stopped it, I got nothing registering.
I had actually just given up on the headphone jack, and was looking into doing it over USB as well. I might just have to do several code paths, depending on what kind of camera the person is hooking up /ponder
Alrighty, I just did some more testing with a quick framework app that I had been working on for this. There is apparently a constant 1.7 mV on the headphone jack, which is enough to trigger the shutter release on my camera... boo urns... and when the tone is played, the voltage actually drops, because as all learned ppl know(at least those who paid some attention in physics) is that according to Ohms law, Resistance goes up, Voltage goes down.
Any progress on this?
I would love an intervalometer on Android for my Canon EOS 550D
+1 for the development of such app & hardware it may need.
i hate to bust your bubble but this died over a year ago
ya, development has kinda stalled out... I realized that it is not possible to do over the headphone jack, as there is always voltage there, and I don't know if it is possible just over usb...
The only way I can think that this would be possible would be to get ahold of a google hardware kit/arduino dev kit, and then program that.
I ordered the Kenwood DDX9902S the other day, should arrived on the 28th and I will install on the weekend.
Going to install in my 2014 Mazda CX-5 Touring with Bose system.
I chose the DDX9902S over the DDX9702S because it's only $50 more and has 2 more bands of EQ and 2 years of warranty vs 1, and some other stuff.
I chose it over the Pioneer AVIC-4100NEX because it can do the screen mirroring and control the Phone from the touchscreen. (Though the damn Nexus 6 doesn't support video out damn it).
It is too bad the Kenwood only has 1 USB input though, and the Pioneer has TWO and also has an SD card slot. Does a USB hub work?
I'll have to do some creative wiring so I can swap out cables for card reader/etc if I want to view movies and such. The Kenwood can playback mkv files, didn't look up if the Pioneer can.
Ordered it from Crutchfield, $749 + $79 for the steering wheel control/wiring harness, free antenna and dash kit. Since it's so new, it's the same price elsewhere on the internet.
The Crutchfield Mastersheet is stupid. It only shows you how to take out factory audio unit and speakers, nothing about wiring at all. If buying stuff is cheaper elsewhere, do it.
Going to wire up my factory rear view camera to the Kenwood, from the Mazda forums, someone detailed how to do it. Got the items today and will get it prepared for next weekend to install by myself. I'll report back, I might also do a YouTube video since this unit is so new and no one has it.

So you expect to mirror, instead of running Android Auto ?
Pioneer is limited in what it can do on each port. I think iPhone/iPod goes to port 2 while firmware updates and Android Auto are port 1.
In theory, anywhere a phone works, a phone plugged into a USB hub should work. But don't underestimate the need to get a quality hub and cables for reliable connections.
I have no idea if the Kenwood supports flash or other USB stuff besides a phone, and at the same time a phone is connected.

No, I will use Android Auto but would like to check out the screen mirroring too, for apps that don't support Auto / 'appradio' yet.
I've downloaded the manual and the Kenwood does support movies and music on a USB flash drive, but no mention of hubs or simultaneously connected to phone.
I just installed the DDX9702s over the weekend. It's a pretty good unit, Android Auto works flawlessly with my Sony Z3, and the external GPS makes it super accurate. Kenwood's interface is so freaking ugly though
Android Auto is also incredibly finicky on my wife's OnePlus with CyanogenMod. I flashed to 12.1 nightlies hoping to resolve some of the issues but it's no better.
The iDatalink Maestro was also fun to install, it requires taping some wires on your ODBII port. My tip there is grab a right-angle generic ODBII to Serial cable on Amazon/Ebay for $10 then cut it up and splice it into the iDatalink Meastro harness. That way you can just plug it in rather than t-taping or hard-wiring the maestro cable to your car. You can also re-pin the ODBII port as well, but splicing an extra ODBII cable seemed like the best option if I ever want to go back to stock.

Doesn't start or what ? Sometimes enabling/disabling USB debugging can help with getting a phone connected.
I saw the news about 1+2 not having NFC. It appears NFC is required to trigger Android Auto over Wifi connections, so that could be an issue for the new 1+2.

Yea, it won't start unless I "forget all cars" and go through the acceptance dance again then most of the time it freezes or just shows a blank black screen. I can't believe how much difference the Sony Z3 is, it works flawlessly every time.

It MIGHT be due to bad USB connections; maybe the USB port isn't tight.
Android Auto tends to freak out if USB isn't a perfect connection.

I'm using the same cable for my Sony though, which means it's the port on the OPO which is only a few months old
I'll give it a shot with the official OPO cable just to make sure.
I guess it's time for USB C.

I'm not saying that it IS the port, just that it's a possibility.
I have about 15 test devices and I don't think any ports are bad, even after years of use.
I DO have cheap USB cables that are pretty bad though.
Trying other cables is the best idea I have, besides wiggling the cable a bit to see if Android Auto stops.

Hey, you were right! The OPO cable works perfectly! Thanks for the tip.
Have the same unit... Love it, look on the Kenwood website, there is a firmware upgrade for our units

Awesome! thanks for the heads up, 100mb.
It says to do a reset after, is that necessary, kenwood has a ton of settings.
nxt, been eagerly waiting for your DDX9902S in depth review. Did I miss it? If so, please point me in the right direction. If not, I'd love to hear your thoughts now that you've been using it for a few months, especially if you've had a chance to compare it to the 4100NEX and from an Android perspective (mirroring vs Auto). Thanks

I wrote a pretty long review on Crutchfield but ran out of space. I ended up not making a video review because... it's not that great.
Just like any head unit, the regular UI for radio/settings/menus/audio/etc is ugly.
Anyways, here's some info going from the HU itself then Android Auto.
The Kenwood only has 1 USB. It charges your phone very very slowly, but it can charge it to 100% if you keep it connected long enough even while using Android Auto. (I do 6-7hour drives every other weekend).
1 USB, so 1 USB device connected and that's it. The Pioneers have a dedicated SD card slot, you can store music on it and leave it in there forever.
Putting about 64GB of music on a USB 3.0 Flash drive, the Kenwood took a very long time to get complete ID3 tags. So I'm forced to listen to Adele when it starts up, or manually choosing another folder before I can shuffle ALL songs.
The Kenwood supports various file formats, it can even play video files! Too bad all the .MKV files I have, no audio is decoded.
Bluetooth audio. Very little lag, steering wheel control to skip tracks almost instantly changes the tracks. My stock HU there was 2-3 second delay. ID3 tags show up properly. I primarily use Google Play Music app. I mostly use Android Auto mode when using to music though.
Bluetooth Phone. Works fine, I have a 2014 Mazda CX-5, I put the microphone where the stock microphone was. People can hear me perfectly. Android Auto voice commands have no issues hearing me either.
I have a Nexus 6 and when it was on 5.x.x, the Bluetooth Phonebook on the headunit would be SCREWED UP. No names, and just a ton of phone numbers. I installed Android 6.0 that was released a few days ago and Contacts information show up perfectly.
The Kenwood's backup camera input works really well. I can turn on the car and as the Kenwood is still booting up, if I put the car in reverse, the backup camera would be displayed! I'm pretty surprised with this and love it. The Kenwood takes a while to boot up.
The Kenwood, like most high end HUs have a TON of audio settings. I'm no car stereo buff so I mostly leave everything at default since I don't know half of what the settings mean. Each audio input has it's own audio setting which is great. My car has the factory Bose system and it sounds even better with the Kenwood.
The Kenwood has built in iHeartRadio/Pandora/Aupeo! "apps" that's supposed to work with your phone. It's junk, I've given up trying to make that work and just do regular Bluetooth Streaming.
Kenwood also has a SmartPhone control mode where if you can get your phone to video output into the Kenwood's HDMI or AV input, you can load the Kenwood App, and control your phone from the Kenwood's touchscreen, so you can use Waze or other apps directly. The app sucks and doesn't get my touches correctly. Don't rely on it, it's not reliable.
So yeah it has 1 HDMI input you can use with your iPhone using video adapter, or Android or whatever else.
It has DVD slot for movies/audio cds, I've never used it.
HD Radio. The radio interface really sucks, but it works. The way to change an HD station from HD1 to HD2 is really dumb and annoying. it has 3 different "seek" modes when you press the >> or << button. Seek1 auto scans to the next station that it can grab. Seek2 is manual seek. Then there's Auto where it changes to your next Preset.
Then there's the CHup and CHdown buttons. So if you're locked into an HD station and you want to change to HD2 you press the CHup or CHdown button, but that only works if you're in Seek2 (or maybe Seek1, I forgot), if you're not, all it does is the same as >> or <<. It makes no sense because CHup and CHdown acts EXACTLY like the >> and << buttons.
I have a ZuneHD with a special car aux box for it, I use it in AV1, works and sounds fine but when I put it into video mode I get a lot of interference. Not sure if it's the Kenwood or my aux box for it.
The Kenwood's video controls suck too. It's just hard to adjust and get proper color/brightness/etc.
At night, it's too bright, and lowering Brightness and "Blackness" levels, it gets hard to see/read the screen. So to make things clearly readable, screen has to be a little bright. There is a way to set holding Menu button and the screen will turn off until you press screen or a button.
OK Android Auto, I won't talk about Android Auto itself, there's many reviews and videos about it. I'll talk about how well it works with the Kenwood.
When it works it's great, but it's a coin toss if it'll work great on this drive, or the next.
Plug in USB cable to the phone and you're prompted to press OK on a warning screen on the Kenwood. The Apps icon turns into Android Auto.
Again, when it works, it works. Here's when it doesn't:
On my road trips, I would get into car, search the destination, and start navigation.
About 5 minutes later, Android Auto on the Kenwood would shut off and you're taken back to the main menu and the Apps icon return. Phone's Android Auto app is shutdown. There's no way to relaunch Android Auto without unplugging the USB and plugging it back in. On my last road trip, I did this about 4-5 times, then I decided to start Play Music while navigating, then it worked and had no issues. On my drive home, I started music right away with navigation and it still shutdown every few minutes. Unplugging and plugging back a few more times then it worked with no issues. It's completely random.
On my drive to work and back home, I drive through some low cell signal areas. When my phone looses signal and then catches signal back, Android Auto's screen would BLINK. Navigation wouldn't stop, music wouldn't stop, the screen would just BLINK. It's distracting.
Phone calls go through Bluetooth still, but it works well from the Android Auto screen. I'm sort of impressed how it works.
It's possible to listen to another audio source (HD Radio, CD, etc) while in Android Auto navigation, just press menu button, pick your source, then go back to Android Auto.
Android Auto I believe needs a lot of work. It's still in its infancy and the missing features and odd limitations Google has with it frustrates and confuses me.
Kenwood released a firmware update 9/17/2015.
Changelog is: Changed the specification of Volume function. Improved stability.
I hadn't noticed any improved stability.
That's all for now. Ask your questions and I'll try to answer them.
About Mirroring vs. Android Auto.
My Nexus 6 unfortunately does not support video out. I'm pretty pissed. The new Nexus 6P won't either, damn it Google!
So what I did to test was to hook up a Chromecast to the Kenwood's HDMI input.
Then I would set up my phone to be a hotspot, the Chromecast would connect to it, then I was Cast my Phone's screen to the Chromecast. Totally going in a circle LOL. (This will eat up your cell data FYI).
But it does work and my screen shows up on the Kenwood's screen.
The issue is the Kenwood's SmartPhone Control app like I mentioned in the above post.
It does not sync up properly so my touches on the Kenwood's screen, does not touch the right area of my Phone's screen.
I've never used the Pioneer 4100 so unfortunately I can't compare.
I believe that having TWO USB ports on the Pioneer and a dedicated SD card slot is BIG!
It's so annoying swapping out my Phone with a USB Flash drive.
If I were to do it again, I would probably get the Pioneer because of the TWO USB and SD card slot.
I chose the Kenwood because of the higher audio capability (EQ) and the App Mirroring (which sucks now that I've tried it), also it was cheaper than the comparable Pioneer high end model.
Hello, I ordered a DDX9702S and installed it in my '09 Civic Si. I've got a Nexus 6P and have been experiencing odd audio glitches, and I was wondering if you could test something for me.
When I play music, everything is fine until I get an audible notification or use the Voice Search. After that there is an audible buzzing/frying noise in the tweeters of my stereo when a bassy note hits. Once the noise starts, it doesn't stop until I reboot my head unit. Could you see if you have the same problem? I don't know whether it's Android Auto in general, my Kenwood stereo, or what. I've also reproduced the issue with 2 other Nexus 6P's and a Nexus 5, so I know it's not just my phone or model. I know yours is a different model, but it's worth a try to see if it's just me.
Steps to reproduce:
App to use:
Either Google Play Music All Access or Spotify
Song to use:
Rearrange by Vérité - the beginning of the song is quiet with a bassy beat, making it easy to spot the distortion / static.
Steps:
Turn on the head unit and plug in your phone (I used a Nexus 6P and a Nexus 5)
Once Android Auto is running, go to your music app and play Rearrange by Vérité. I find its easier to play the song if you add it to a playlist titled "1" (without the quotes) first, so it's at the top of your playlists.
You'll notice that the beginning of the song is quiet with a bassy beat. After about 10 seconds, hit the microphone in the top right of the screen to activate the Google Now Voice feature. Once it gives an audible beep, hit the microphone button again to cancel.
Hit back on the screen to start the song over. At this point, on my stereo, every bassy beat is accompanied by a static in the tweeters of my stereo. This happens on every song I play, even the radio, but it's much easier to hear on quiet songs like the one I gave as a suggestion to test with.
The static continues even if you disconnect/reconnect the phone. The only think that stops it is restarting the head unit by turning it off and back on. If you use Google Now again or a notification comes in and makes an audible sound, the static will come back. It seems, to me, that any notifications or audio playback from an Android device will cause the head unit to distort the sound until the head unit is rebooted. If nothing happens to cause the distortion, sound quality is stellar.
Hope you're able to test this, and thanks in advance!

TPMS has beenn mentioned a few times in the original thread, but AFAIK no one has managed to find out how/if any TPMS modules will work. I bought a TPMS module from Klyde, it comes with 4 valve caps and a strange mini USB thing that I assume allows you to plug another mini USB device into the unit at the same time.
Unfortunately I cant get it to work with the built in TPMS app that started appearing in ROMs from June either on my old unit or my new one, I ve tried searching for the device in the BT app and the BT in settings but I get nothing, I m awaiting a response from Klyde.
If anyone has any ideas on how to get it to work then let me know, but its good to see TPMS hardware available for these devices - even if its not working . . yet !
Can you share link from TPMS module?
My brain is stuck what is TPMS? I am sure I should know but i don't get it
Guess youre talking about Tire Pressure Metering Sensor?
would you probably add a hint to your OP and title so others know what you mean? Remeber the non-english-speakers here
Yes this is it (Tire Pressure Metering Sensor).

I simply bought it from Klyde, there was no link, I guess you have to ask them.
It turns out it cant be used with DAB, which is why I cant get it to work - the cable to attach it is the same as the DAB module they sent me.
I m not sure if its BT or maybe NFC or something. I ll report back with results when I get it to to work
Does anybody try this TPMS solution with his HU?

Does the app work in landscape mode?
Can the app start with background mode?
Does the external (valve cap) sensor show accurate value?
I have been using this TPMS system in Volkswagen Polo and my MTCB head unit since 3 months now and couldn't be happier with it.
It activates when you press the button because it invokes the reverse camera display source every time you call it into action.

I have tried these two models purchased at Amazon and they work perfectly. I have them installed on my cars.
The only drawback is that you need Bluetooth 4.0 and HuiFei radio does not have it. I have commissioned an RX USB Bluetooth for Android on Deal Extreme, to see if it works.
So far I'm seeing it in my S5 Galaxy.

But in any case if it works with a Joyous unit it will work with ANY MTCB head unit. There is no such thing as a "Joying" head unit - Joying/CarJoying are simply re-sellers of Shenzhen Joyous head units.

Yes I think.
It looks made specifically for these HUs. So I supposed they tested them.
And screens look like built-in TPMS app that I got preinstaled on my HU (KGL). So I supposed it should work.
But I would preffer ecternal sensors, not ibternal ones. I have 4x4 which reqiires regular tire rotation and ibternal sensors are not suitable as I would need to remove and refit them on every tire rotation.
Is there external versio? I couldnt find it on AlliExpress.
The one I mentioned in my first post has valve mounted sensors and obviously works with MTCB head units

Why? Sure, if they are somehow hard coded to location its sort of funny when they might not match the picture, but you only have 4 tires. Its pretty easy to check them when they are low.
You want internal sensors for TPMS. Less chance for losing them.

I understand the point about tire rotation and internal sensors. Would it be possible to make the same rotation in the app, since all sensors are doing the same thing anyway? Eg. If you rotate your right front to right rear, make the same in the app to correspond with the sensor location?

Yes, mapping is possible. Depends on product.

Hi All,
I have also interest for this. Somebody could give some information ? It works, or any other bluetooth type, using with external attached bluetooth 4.0 dongle ?
Well, I found out most of the connections for the TPMS as Klyde didnt send me a lead - power and ground were easy same as the DAB box, then, as its just a mini usb connection its just data + and data -, I know where the one of those wires goes, and narrowed it down to 2 pins for the other, I ve tried both pins and several versions of the TPMS app, but cant get anything. I ve tried looking for BT devices on my phone I thought I found 1 but my phone wouldnt connect and the headunit's BT wouldnt see it, my phone wouldnt connect and after removing all the batteries on the TPMS it still showed up so it couldnt be that. Totally stumped, just cant get it to work.
TPMS-Type
Let me inform you that for some time I'm trying to find a TPMS system that works well with Android auto MTCB-C I have made several purchases and placements from various vendors I will mention my experience to help future stakeholders.
For GS, KD, and JY machines, the following set works very well:

It has its own very friendly app and it works with automatic start-up in the background and immediately informs if something goes wrong with the tires of the car, I recommend it for the above!
But last time I discovered another type with external valves that works very well with a Klyde machine and that's it:

Thanks for your post - I have the Last type, Klyde themselves supplied me with it, but they did not send me the lead and they did not reply to me when I asked for it, so I had to make one, but I still cannot get it to work, could you post a picture of the lead (the end that plugs into the head unit) so I can see which wires go where (I have seen the picture in your 3rd link before, but I cannot see where all the wires go) ?
I'm looking to get a single DIN flip screen style head unit. Looks like there are really only 2 quad core options out there:
Eonon GA1312: Seems to be relatively popular Klyde design and shows up under a few other "brand" names. It meets my needs but the basic downsides here being the 800x480 screen and typical lack of an external microphone. From a Youtube walk through it looks like it is a KLD5 MCU.
Erisin 3090A: This looks like an upgraded quad core version of the Erisin 8990A (dual core system). This unit has the upsides of a 1024x600 screen, an external microphone (important given this is going in a loud sports car), options for DAB radio and DVB-T TV (not useful here in the US), and a removable face plate. (I can't post links but the specs are posted at the first google search link for "ES3090A")
Needless to say the Erisin looks like the better on paper, but I'm hesitant to pull the trigger. Anyone have any experience, thoughts, or comments on this unit?
I got both.
Eonon GA1312:
Bluetooth is total crap , no one can hear you in a call .
Missing 3g apn setup
unable to change panel leds color, they are blue and blinding.
no detachable front fascia
front usb and front audio in
Simple to root with a password.
Some apps cannot pass the initial screen due to low Res.
Shutdown timer does not work.
It has configurable reserve camera lines
Erisin 3090A
Bluethooth calling is great plus it has an additional external mic.
Device seems to have 2 Bluetooth devices , one for the phone and other for android
Any color you fancy for the panel leds
detachable front fascia
Can only be rooted via king root ( i was able to replace king root with superuser)
missing multitask button.
No front usb or audio in.
Shutdown timer set a 10 seconds, unable to change so far.
Dos not have configurable reserve camera lines ( most cameras come with lines integrated anyway.)
Both units have the same cpu.
Both units DVR are crap,most of the time they ether crash or fail to start.
The Eonon GA1312 has most setting integrated into the android control panel while the other unit has several other apps to change settings.
Also the Eonon GA1312 seems to have slightly better sound out of the box.
Hope it helps

After extensive reseach ,I also considered a couple of options.
I have a supra mk4 1993. It's double din sits quite low, so opted for a single din with fold out display. So i used the upper part of the space..
Also considered the dvb and TV for posible future uses.
Also there is a reverse camera input with reverse sensor contact as well as the expected dvr with the plug and play USB camera.
I tried a couple of USB cameras and the unit crashed or the app crashed, thought it was a pile of cap,* however I read that it has to be the camera supplied by Erisin. After purchase, the camera has been 100% . Dvr loop, 3 ,5 and 10 mins with option to use specific memory, adjustable up to 500mb.
Not tried the reverse camera as yet.
The Bluetooth works well, I have connected the android phone via Bluetooth for music and the torque unit. They work as expected.
However I did find that on occasions, the phone would knock off when I tired to activate the obd2 Bluetooth adaptor. ( got a converter adaptor on ebay £14)
I got around this by connecting the phone first.
I've not yet tried to connect 3 or more devices as yet.
The 4 really annoying thing are,
1. When on a Bluetooth call, you cannot access the android unit. It seems to lock on to the call screen.
2. Fast processor,* my arse.* More like missing a couple of cores. Slower than my galaxy s5. But fast enough for the pleasures it brings.
3. The Google voice app and other voice apps say error when trying to use. "Mic not working", (something like that).
The mic works normal on the phone and the voice memo apps.
The same happened on another new unit.
4. It seems like there is a limited memory for apps. Can't seem to change where they are stored.
I got about 6 apps totaling around 600mb. And it ran out of storage.
Other things like no AM Radio.
The screen only folds up to 90° angle exactly, so if it's low down on the dash, it may be an issue.
No mic on the dvr they provide,* or the app doesn't support it.
The Satnav could do with having the speed cameras info. But It didn't,* it does have the option to warn for it and others, in the settings though.
The WiFi works well if very close to the antenna otherwise seems to go weak very fast when creating a small distance.
I tested it with a new extended wifi antenna, and actually got a slower speed, but that could be a faulty lead!
I actually was able to test 2 units as I wanted to make sure that my initial unit was working as it should.
And it was. So I returned the second unit after extensive comparisons on data speed and app response times etc.
Despite the problems, I am sure I made the correct decision.
Amazing piece of kit considering I'm updating an old double din of 10 year old with satnav etc.
I use it via a "hotspot" , from my phone. Works really well.
Memory locations and availability work well.
Sound is great.
Ended up costing me £215 after I complained about the mic thing.
I'm sure that another app is blocking the mic from working on the Google thing and other voice apps.
Any or update would be really appreciated to help with my issues above.
I hope I have been of some help.

Is this a MTCB unit? Can I install Malaysk ROM on it?
Hi guys,
I have thoroughly searched the forum, but I could not find an answer reffering to the use case of the car running android auto on the phone, not on the head unit.
Summary: is there a way to reproduce the rear camera functionality of a headunit running android auto in your phone instead?
I am aware there are video WiFi transimiters, also available apps to go with them, pick a rear camera from amazon and off you go, by launching the app on your phone, you can now see the rear camera.
HOWEVER, if android auto is running I would like this app to launch automatically as I put the rear gear in (hence, enabling current to the camera and having something to look at). For the apps and wifi transmiters, it seems they are built to just be continually run, not only on rear mode. See on youtube "DIY Inexpensive Digital Wireless RV Backup camera- Review EC170 and 903W TrA" (can´t post a link since I am a new user!)
It seems like the apps available are linked to a particular wifi transmitter? Or are they available for any device?
Do you know of an app that as soon as current is given to the rear camera, it will launch the camera app (overriding android auto typical screen, just like it happens in AA headunits with rear camera), and as current is cut from the camera, the app will shut down and let AA continue its business? (all of that without shuting down AA in the first place, just overlaying the camera view).
In case an app like that was not available, how difficult can it be to program? I could potentially be willing to pay.
I am not sure if I explained myself correcty. Let me know if you have any further questions, thanks in avance!
I doubt it. Head units which support cameras do so outside of AA (the camera simply takes the screen away from AA). And they have a wire connected to the backup lights to signal when to switch to the camera. And I'm not aware of any backup cameras which use WiFi or Bluetooth (which doesn't have enough bandwidth anyway) - they're either hardwired or use a proprietary wireless link to a dedicated receiver which connects to the head unit.
So, there are three problems to solve. How does the phone know the car is in reverse? How does the video get to the phone? Even if you found a WiFi backup camera, you'd need to be running a hotspot on the phone, and the time it would take to connect would be unreasonable - head units only take a second or so to display when you start backing up.
Finally, what's the app which ties it all together? Even if there were solutions for the first two, simply buying an AA head unit would be cheaper than paying for an app to be developed. So, why not just buy a head unit? Or even just a backup camera solution with its own screen?
