Tablet as in-car head unit able to connect reversing camera? - Android Auto General

Hi,
I am restoring an older Mercedes and am considering using a Samsung Galaxy Note Table in my dash.
It would be nice to connect a reversing camera, but is this possible? I have found a reversing camera that uses a wifi connection.
But the problem with that is that the tablet drops any existing internet connection when it then connects to the wifi signal from the camera.
Ideally a wired camera connection would be best because it would show an instantaneous image.
Other than buying a head unit with camera connection, is it possible to wire in a camera to a tablet?
I could then use all of Android Auto Apps etc as well as a reversing camera all on the one screen.
Any suggestion?
Cheers
Rod

Bluetooth through walls?

Hello.
Does the bluetooth on your Kaiser or Tilt work through walls?
I have a mac pro which has a very good strong bluetooth signal and I can connect to it via nearly all of my other PDA's however my Tilt cannot see the mac pro through any walls.
I have tested the range of the bluetooth by placing the Tilt on a table and playing an mp3 to my Jabra BT620s's and in direct view of the phone I can get about 25 ft from it which I believe is quite acceptabe but the minute I try to connect or maintain a connection throught a sheetrock wall it cuts out.
Does anoyone elses unit do the same thing? Or do I still possibly have a defective unit?
Any ideas?

Am I the only one who notices this?
BT uses the same 2.4 GHz frequency range as 802.11b, so it should theoretically work. However, BT uses somewhat less power than WiFi, so you may not get the same range.
I have a Sony MEX-BT5000 radio in my car, which is paired with the phone. My garage is about 20 feet from my living room, with one wall between the two rooms. Sometimes, when I forgot to take my old Wizard with me, I would notice the Sony pairing with the phone, only to lose the pairing as soon as I back out of the garage. So it is possible for BT to connect through a wall. However, I haven't forgotten my Tytn II yet, so I haven't been able to test its BT performance.

Thoughts? Erisin 3090A - Single Din, quad core, 4.4, 1024x600

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?

Rear camera view on PHONE running android auto

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?

Reverse parking camera has no signal - please help

Hello my friends,
My problem is simple, I have installed Android head unit to Opel Insignia 2010.
After connecting the rear parking camera, the unit always says just "NO VIDEO SIGNAL"
Here is what I have tried:
1. Connecting via cable: "yellow (video) in" to the unit, "yellow (video) out" to camera + power (black) ... after that I have tried all video settings: PAL NTSC .....
2. Connected same way with wireless signal transmitter. Power was connected correctly (led indicators was on).
3. Repeated point 1. and point 2. but this time I have connected an additional video input to the head unit.
This leads me to two options, brand new camera is broken, or there is needed an additional software or software settings.
Maybe I need to check the car fuse? Is it needed to have connected also the button for parking sensors ON-OFF?
Please let me know if you have some experience.

Android audio

Hi, first post so bare with me.
I have a android head unit in my vehicle and a samsung s10 5g phone.
Every time I switch the ignition on and they try to connect the android audio on my phone never seams to connects. It seams to be continually searching for a connection with the head unit.
This blocks the phone from connecting to anything else. I.E maps.
Wifi and Bluetooth both connect with out any problems.
Photo of Head unit system attached.
Any suggestions on how to fix this problem would be appreciated.
Thanks Andy.
