[GUIDE] HowTo Make a Mazda RX8 Streak

This guide represents a current WORK IN PROGRESS. Development is currently underway for Streak 7 OTG functionality including consideration for FTDI Serial2USB kernel module and HU Integration via custom Android Activity & Service, and breakdown of the Home Dock for stealth installation and OTG support.
While this guide focuses on Streak integration with a Mazda RX8, the concepts, tools, and many of the components can be utilized for a multitude of other platforms.
MODS: If you'd rather this be in General or Apps & Themes, feel free to move it. Simply bear in mind that I plan to provide source and binaries for a custom FTDI kernel module (if necessary), steps for installation, as well as source and binaries for any Android Activities and Services I build for Integration.
I've been running a Windows 7 mini-itx carpc for quite some time on my RX8. The system consists of a ITX case I keep mounted in my trunk, USB GPS, RS232 to OBDII wired connection, a Grom Car2PC HU Integration adapter with a bunch of custom code for HU and Steering Wheel controls integration, and a Lilliput 7" Resistive touchscreen mounted in a Mazda Japan Retractable Navigation tray.
I deliver clean power to the PC using a Carnetix P2140 power supply with a bit more custom code for ignition synchronized hibernate and wakeup.
For the past year I've been waiting for a good Android tablet replacement and have landed on the Streak 7.
Dimensions wise the Streak 7 matches the typical Lilliput 7" exactly.
This project requires the following additional hardware for your RX8
JDM Retractable Nav Tray
SlipGrip RAM-HOL Mount
Streak 7 Dell OtterBox (Commuter)
Streak Home Dock *
3.5mm Audio cable (possibly with MIC splitter)
Grom Car2PC Adapter
Here is a picture of the Streak running OBD2 and HU Audio integration via the Streak audio out jack and a bluetooth connection to a generic ELM OBD2 reader.

Post #2 illustrates adapting the Mazda Nav Tray and SlipGrip mount and dash installation.
You need to mark and drill two holes on the JDM nav tray's center plate for mounting the SlipGrip Streak holder. I also used a wood shim to provide a solid mounting surface between the center plate and the holder.
Here's a shot of the Navigation Tray fully assembled, ready to be installed in my dash.
Remove all Center Console components.
Wiring and Mounting complete (temporarily using the Streak 3.5mm audio plug for HU integration to my Car2PC module).
And all stealth like when not in use.

If you're planning on taking apart a multimedia dock, I'd be interested in high/higher res scans of the pcb and the wiring diagram of it for the wiki.
Some of it's pins are known, but the info is all over the place

I've got a DLSR so no problem. I'll be out of town for the next couple days. Should have an update by next Friday.

Nice work so far; looks very clean and professional. Are you running Torque app in there?

I have torque lite installed... Have been using dash command too.

Sorry for the delay... finally got to dismantle my dock and take some pictures.
Hope to have it integrated this weekend.

Very cool. This is almost exactly what I wanted to do except I was thinking docking the tablet directly into the dash but that works very well too
I am interested in the pin out as well. I am going to be swapping the stock PDMI connector for a micro USB soon. My PDMI connector bent a pin inside and is now shot...

I had originally wanted to use the dock too but have been unable to source a PDMI extension cable. Even unboxed I dont have the real estate to mount to it directly.

I will be mounting the dock into the center console of my dash. The dock will be mostly hidden with just the front end and pdmi pins sticking out enough to set the SD7 directly onto the dock and sit flush against the rest of the dash. My local audio shop is comming up with some interesting ideas on how to secure the dock and then have some way to keep the tab secured.
The dock will then connect to an after market head unit through the 3.5 output in the back of the dock and connect as an six input in the back of the headunit. Dock will be hard wired to the battery so that all wiring will be hidden in the dash.
Then I will chose option to "keep screen on while charging" so that when I power on the car and power is fed to the dock the screen will automatically power on. The head unit also has a usb for a flash drive worth of music when the streak isn't being used, as well as ipod input and built in control and ill have the ipod wire run to the glove box.
Essentially, tethered to my cell, the streak 7 will act as a secondary removable HU, internet ready for things like navigation, add free Pandora with unlimited skipps, I've got grooveIP working flawlessly to make and receive phone calls through my Google Voice, I plan on adding a Bluetooth obd2n unit to display car info in real time through something like torque, I'm waiting for the GoPro WiFi bacpack to be released this summer and ill have a front or back end cam displayed through the stated GoPro control app comming to Android when the WiFi backpack is released. I've even got two headrest monitors that will eventually be fed by the hdmi output from the dock.
I am excited, been a long work in progress(with no work taking place lol) and the set up gives me tons of input options and allows me to pick up my ds7 and go just like any removable face HU, except I get to play with mine when its detatched.
Any other ideas for apps or what not, I am all ears. Something that isn't working on my streak right now is voice control... That will be needed while I am driving! Check the beta4 thread

Does the Dell dock have any sort of remote control? It would be awesome to set up your steering wheel controls to function with the DS7. Another possible option would be to use a bluetooth keyboard wired up to your steering wheel controls and then a programmable input in the Android system such as a game controller app allows programing of simulated keys.

my vehicle is a '06 Mercury Mariner... basically a nicer version of a Ford Escape.
there aren't any steering controls, i'm not to concerned with that as of right now, but i do like the idea of a Bluetooth keyboard. I was looking at some mini keyboard options from amazon/ebay/dhgate. one with a built in track pad or some kind of mouse pointer control perhaps?, I could just pass the keyboard around the car and let my passengers have some fun(browser and app input? search for an app or music selection?). but I do like that idea of perhaps assigning key presses to do things like volume control or to jump to a particular app like maps?
the dell dock has no remote control options. I am curious how many different Bluetooth pairings I can have before causing issues: headset first for use with GrooveIP for incoming/outbound phone calls-next would be keyboard-then OBD adapter.
I plan on strictly using ICS on the streak. I'll need to make sure I will not have any compatibility issues with anything I do. I've also never attempted to pair a keyboard with an android device... but I guess Ill buy one and ask questions after and return it if it doesn't work.

I personally have not used a keyboard either but I know people use them and a mouse all the time on Android devices. I like the ideas you have. One question, what is an OBD adapter? I might know but am just not getting the acronym.

Plugs into the cars CPU and transmits information. Look up "torque" in the market. Basically sends data to an app that will display real time on an android device..... think guages

I have full HU integration with the Grom BT adapter and have developed my own communications library (and front end) for interfacing with my car's ECU.

Awesome. I follow now. My aftermarket ECU for my Mitsubishi allows for a laptop to do the same thing plus obviously change the program. That is really cool that you can monitor you vitals using an Android tablet now.

I'll have to set aside some time to update this thread at some point. There's a lot of stuff I've implemented that I haven't captured here yet.

New and Complete Car Installation

After mainly lurking on the forums for a while, I decided to embark on a Nexus 7 Installation as I wanted to have to same features found in newer vehicles in my 2000 Mazda Protege. The only problem is I didn't want a permanent installation and didn't find previous posts to be complete enough other than to get some ideas from. I didn't like the fixed installation because the screen in most setups doesn't face the driver and doesn't appear to be useful. In addition, I wanted to be able to remove it especially in the summer when conditions in the car may be dangerous to the device itself.
The goal of this post is to give very detailed account of the setup up, how it works, and what my future plans for improvement are. I would also like to try and answer as many questions as possible for people considering doing the same with their own devices.
Video
First off, we'll start with a quick video of the installation in action. It may seem a little low in volume in the video but all of the sounds and music are playing through the car's speakers. As such, you can make it as loud as anyone could possible want.
Pictures
First up is the view from about where the driver would see. In reality, the steering wheel does not obstruct the screen.

Next is where the hub is currently placed. I don't yet want it completely hidden because the signal strength is displayed on the freedompop stick. It can be pushed down and out of sight from here.
And the hub in all its glory.
This is the view from the back where you can see the fish eye lens protruding from the trunk lid.
And now with the lens removed. Its still unfinished but I wanted to get a working prototype. I just need to sand down and seal the opening to prevent rust.
The MIMO antenna for data connection is just attached to the passenger's headrest for now. The wires are pretty short so it may end up staying here for now.
The FM antenna is currently placed in the back by the rear window. I live pretty far from the station so I needed something bigger for a clean signal.
A view of the power inverter. The hub takes up the plug while the Nexus is powered via the USB port.
And finally, a diagram showing the buttons of the bluetooth remote and what they do.

Software
Here is the complete list of the major software components used in this installation.
USB ROM for Nexus 7 with Timur’s Kernel
Webcam Hotswapping by redeyedjedi
SDR Touch
Torque Pro
Backup Cam (Mirror)
Tasker
Spotify
iHeartRadio
External Keyboard Helper Pro
Assistant Event for Tasker
Hardware Set Up
The Nexus 7 is mounted on the dash with the tablet mount, facing the driver. Its placement allows for easy viewing while not obstructing vision. From there, a 3.5mm audio cable runs for the headphone jack out into a PAC Ground Loop Isolator to eliminate the alternate whine and other electrical interference. This finally plugs into the AUX input of a cheap aftermarket radio I installed to replace the stock.
Coming out of the micro usb port is a Micro USB OTG Cable with power which connects to a powered USB Hub. The hub and device are powered by a 12V Power inverter. Everything should be able to be powered just through the OTG cable but I was having some charging issues early on which I rectified by disabling some apps from logging and constantly using the GPS but I kept the setup as it worked well.
On the hub are the Freedompop Bolt, RTL2832U dongle, and USB extension. The Freedompop Bolt I got a deal on over the summer which gives me a gig of free data every month which the Nexus used for its primary data connection. The signal strength can vary pretty dramatically out in NC where I am so I also installed a MIMO Antenna to improve reception and also have cell tethering as a backup in a pinch. The RTL2832U dongle is connected to the passive antenna for better FM reception which required some adapters listed in the Hardware Section. The USB extension cable runs from the dash, under the seats into the trunk where it connects to the USB webcam mounted in the trunk lid. I drilled a hole through which a fisheye lens attached to give me the backup cam.
Connected to underneath the dash is the bluetooth OBDII adapter which feeds realtime data to the Nexus and is displayed on Torque Pro. I enjoy knowing as much as possible about the car and actually end up using this display over the instrument cluster.
The final piece of hardware is the bluetooth remote mounted on the steering wheel. The buttons are remapped to various apps allowing complete control of the Nexus just using the left hand. It only took about a day to completely memorize everything which allows it to be operated without taking my eyes off the road.
Software Set Up
On the software side, The Nexus is running USB ROM with Timur's kernel which provides a fantastic base to start from when it comes to car installations. In addition, redeyedjedi's mod was installed which allows for hotswapping of the webcam as long as it was plugged in at boot. This means once everything is set up correctly, I can remove the tablet for whatever reason and when I plug in the USB again, everything works like it did before without any reboot needed.
Torque Pro is used to read and display all of the realtime information as mentioned before. SDR Touch taps into the RTL2832U dongle to give me live FM radio which is controlled via the bluetooth remote. I have the mainstays of Spotify and iHeartRadio for music in case I have poor reception of radio or just feel like something different.
Getting the webcam to work was tricky because most apps have the display rotated 90 degrees are have too low a refresh rate such that the feed to too choppy to be useful. I ended up installing Mirror because it gives me the correct orientation of the image and has a high enough refresh rate.
Like any good setup up, the Nexus is used for Navigation which is quite nice on the large, 7'' screen compared to my HTC One which I used to use. Google Now can be launched via the bluetooth remote allowing for voice commands to be given to set the location. Having all of the media run through the Nexus means that when navigation is speaking, the other sounds are muted and the directions can be heard clearly. This eliminated the problem of having the GPS drowned out by the radio which happened all too often with my old setup. It should be noted that I cannot yet get SDR Touch to muted or lower its volume when Navigation is speaking yet so that can be a problem sometimes.
Anyways, this is meant for people to follow along if they would like, get some inspiration for their own projects, as well as get some feedback on my own and how it can be improved. As of right now, I'm not looking to completely hide everything because it's all still being tested. I am, however, looking for some thing which can be added on to possibly make it even better. Some things I have already considered are putting a bunch of music on a flash drive for another source of music in case of poor FM and data reception.

Awesome work, i'll try to follow it. thanks for this guide

Is the dash mount sturdy enough to reduce vibrations/shakiness from driving?

Yep! I love this mount. It is solidly stuck to the dash and the Nexus doesn't move at all even when you hit a pothole or something.
Also, if you are using this guide as a reference, I am testing a new radio antenna setup. The dipole I was using was too directionally dependent and I would lose signal depending on the car's orientation. I'm testing a set up where I splice into the car's antenna and so far it seems to be working well. Once I finalize the setup, I'll update the OP.

This is awesome. In the back of my mind I've been thinking about doing similar, it's so awesome to see it in action. Good work!

Interesting setup with all the extra antennas!
Question about the cam...
You mentioned refresh rates and all. What about lag or delay? Is there a delay in the video when it hits your screen?
Or was that fixed with the Mirror app?

Nice setup. I have a question about your FreedomPop dongle. When your Nexus comes out of sleep mode, does it automatically reconnect to the dongle/4G? I have one as well, and it worked fine when I tested it on my bench but once installed it doesn't seem to want to work.

Backup Cam (Mirror)
Can you please post a link to the Backup Camera App you have used... After much searching I still cannot find it...

This is the ugliest car install I've seen, obviously aesthetics aren't an important factor for you.

That's the ugliest comment I've seen. Obviously, reading the post wasn't important to you. There's no reason to hide it and make it look good if it's still in a testing phase for different items.
Great post aviola, interesting choices in parts and a very good breakdown for people to gain ideas from. Very good point about keeping it removable, because summer car heat can really obliterate pieces/devices that are out unprotected.
:good:

thanks so much for this guide. :good:

Sorry for the delayed responses. With the semester finishing up, I keep forgetting to come back to this thread

I have no real issues when it comes to lag. Initially, when I was using camera applications, there was a good 1 second delay between what the camera saw and what the screen showed. Installing the mirror app reduced the lag to a point I don't notice it anymore.

Here is the link for the Mirror app I have been using:
https://play.google.com/store/apps/details?id=com.yuvalluzon.mirror
In terms of updates, I have successfully tied the tuner into my car antenna for the best reception. I installed a splitter so that the car radio and usb tuner can be connected simultaneously. SDR is good but doesn't do as well with poor reception and there are some times I would rather just use the radio rather than the whole setup.
I'm still having power issues where the the screen on max and GPS navigation use more power than the tablet gets. I'll probably do some testing with a multimeter to see how much power is actually getting to the tablet but for now I have to take the Nexus in about once a week for a full charge up.
Aesthetically, I don't have any plans as of yet to hide all of the wires. I'm constantly swapping stuff in and out and don't want the hassle of dealing with running them through the dash or anything. As the majority of people have correctly observed, this is a proof concept rather than a formal installation. My objective in posting this was not to provide a complete step by step guide for people to follow as there are already several excellent threads devoted to this. This was meant for people to get ideas from so they could build their own installations with their own equipment.
Thanks everyone for all of the positive feedback. For anyone with questions, feel free to continue to ask and I will do my best to be more timely about answering them. If you need more in depth or specific information, that's really what this thread is all about. I anticipate changes to my setup will come slowly but I'll try and update this with the ones that have been proven to work.

Hello, Huawei E3276 works with Malaysk's rom.
I have a Huawei E3276s-150. First I'd accidentally updated it with the HiLink firmware (22.470.13.00.00), but I've found a post where people said if I navigate to 192.168.1.1/html/switchProjectMode.html I can switch it back to normal mode. (You may have to try the URL a few times, if it doesn't work for the first attempt.) In normal mode I was able to flash the 21.491.03.00.00 firmware. I think it might be a solution for people with E3276 HiLink modems. Then I'd set modem only mode with AT commands, using Tera Term. (Check this out for modem only: http://superuser.com/questions/586049/how-to-force-a-huawei-e3276-lte-modem-to-only-mount-as-a-modem)
Now if I connect the modem to the HU it connects to 3G network in a few seconds.
About unlocking huawei modems, well, google it, it costed me a google +1. Totally worth it.

This quote is from the Uber Mega Huge Thread Huifei
I can't make mine work as it came to my hand, I still don't have the modem symbol as @dsa8310 so many times said. Already installed PPP Widget, PPP Widget 2 and Mobile Network Settings. All of them alone, or together with each other or all, with or without Externally powered Belkin F5U404-BLK USB hub in all USB ports from the radio. Does someone knows something that might do this or other hub not work with the radio?
Next step is the dongle's firmware... The quoted above post points to a link that might not be avaiable in the future, so I'll also quote it.
How to force a Huawei E3276 LTE modem to only mount as a modem?
I have a Huawei E3276 LTE USB-modem and I need to force this modem to only mount as a modem when connected to the computer. Per default, the modem also mounts as a CD-drive and a USB mass storage device, which is fine when used with a computer, but a problem when connecting it to a router or similar.
What I've read so far is that you can use PuTTY or similar to connect to the modem over the COM-port, and then send AT-commands to it to configure the modem to only mount as a modem. The AT-command mentioned for most Huawei modems is AT^U2DIAG=0 but when sending it to my modem I receive ERROR in response, which doesn't give me much to work with.
I've also tried AT^U2DIAG? which is said to work for some Huawei modems to display the possible values for this property, but that returns ERROR as well.
I've tried other AT commands, like ATI to get information about model, IMEI etc. which work just fine.
Is there some other command I can use to do this, or is there something else I need to do in order for this to work?
Click to expand...
Click to collapse
You can use these AT-commands:
AT^SETPORT? - show current mode
AT^SETPORT=? - show available modes
AT^SETPORT="A1,A2;1,2,3" - set "only modem" mode.
Make sure you write down the current mode (using the first command), just in case you want to revert any changes at some later time.
After sending these commands you have to reinsert your modem.
Click to expand...
Click to collapse
You should use this command
AT^SETPORT="FF;1"
This command disables all ports excepting the modem port.
I guess you have already solved your problem but I hope this will help other users having the same problem, since I have spent a couple of hours trying to find the solution.
I have a HUAWEI E3131 modem (issued by RCS-RDS in Romania) and now it works with a Edimax 3g-6200n router

@anyuzo do you have recommendation before I start playing with the dongle's firmware? Mine is already unlocked. Do you think I might have benefit in test it first, in modem only mode first? What's the difference between Hilink and Normal firmware? I found a page that has a very nice amount of Huawei's firmware but it doesn't have the version 21.491.03.00.00. Do you still have it? Can you share it? Google only points to Russian or Polish sites... I can't read cyrilic alfabet... yet

I screamed victory to soon, the connection falls after a few seconds. Adding the USB hub make the radio not recognize the dongle... I guess I need a different hub...

Because ultimately the objective is power the USB ports with a Dc-Dc 12v to 5V converter, and my ports connect to the radio by this cable
My idea is power the USBs directly in the cable; disconecting it on the plug, and connect the wires to the converter. 3A should be enough to the dongle
Here is the one I bought

Ok, after dismantle a 700 mA car cigarette adapter to directly power one of the USB plugs I arrived to the conclusion that it's almost the same ending. Even with the dongle directly powered, 2 things usually happen;
1 - The dongle's blue light stays fixed saying the dongle is connected, but google chrome says no internet.
2 - The dongle's blue light stays fixed saying the dongle is connected, but after a couple seconds the connection falls to blinking again and the reconnection doesn't occur.
Before I wasn't able to add an APN, now I can. ( Apparently it means the HU already detects the modem. )
Any input?

700mA might not be enough power to run the dongle. I would use at least a 1 amp or 2 amp power source and try again.
The dongle should only draw as much power as it needs.

You are completely right. I had to tear all apart again, and again cannibalize other 1A adapter but even tough it's not perfect. PPP Widget is unable to auto connect and the connection lots of time must be restarted, not sure if is lack of energy of it's a network issue.. I'm waiting for some ebay 12 to 5v converters with 3A to try it again.

For any one who wants to do the MTC Sound MOD on the KD-C0250 here is how I got it to work.
MTC Sound MOD:
This option removes the resistors and can be undone by the adding the resistors back in place and retuning the headunit back to stock.

WOW!
Excellent drawings.
Can you do the same drawings for 7floor's original mod? This would make the picture so, so better to understand.

Searching the terms "MTC Sound MOD" only returns this thread... so the question is:
What is the MTC Sound MOD?
Thanks

Use of SPen on Dex Mode

Hey everyone, i have an issue with my new Note 9 and its Dex mode. I've contacted Samsung's reps but no responses after 1 week now.
My issue is: if i connect my Note 9 to Samsung's Dex Hub (1st Gen) OR a 3rd party usb c to hdmi adapter (the Meopolow one) i cannot use my Spen to control the cursor on the screen or write on the phone's display and see it on the TV.
I've seen now more than 5 YouTubers doing this on their Notes.
I even have a visual clue about this missing feature - after i connect my phone, in the notification area i get a different notification as opposed to what i saw on YouTube. I will provide 2 photos for you to see what is different. If anyone can help i would appreciate it, i really need to make this work.
PS: the screenshot with blue annotations is on my phone, the one with the green band is from YouTube. Look where it says "use your phone as a touch pad

Works on mine, but it still kinda sucks. It asked me to turn my phone sideways to use the S-Pen. The best way I've seen is to connect a Bluetooth mouse to your phone.

I am switching to landscape and i tried with and without keyboards or mice. The thing is .. and you can check... You wont have that text in the notification area whether you keep your phone in portrait or landscape

Were you able to figure out what was wrong? I have the exact same issue you describe and nothing I've tried seems to work.

Yes I did.
The issue is with the Samsung's Dex Station (1st generation, the one like a hockey puck). It will not work with it.
Samsung's techs argued this: "since 1st Generation Dex Station is intended to be used with the phone in portrait mode, and the use of Spen requires landscape... it will not work".
To which i replied: "But we do have the possibility to run in landscape, if we double tap de "icon" in the top right corner it switches to landscape... also this can be verified by pulling down the notification area, which now comes down from the power button and not from the sensors side; also i even switched to landscape the whole thing, dex and phone....still no go".
They replied back: "It doesnt matter that you switch to landscape, the function needs to work with a device that can have landscape capability, and Dex 1 doesnt". The tech guy who called me, while on the phone, tested 2 Dexes himself and confirmed it will not work... its not just a tale"
I was about to accept this, but i told him I have a 3rd party usbc to hdmi (Meolopow) and it doesnt work with it either. He said, unfortunately its not Samsung, so from out point of view the reasons can be different, we cannot offer support for this.
So, i went and bought myself a Samsung adaptor (1x usb 3.0, 1x Gigabit Ethernet, 1x Hdmi, 1x UsbC) usb to hdmi.... and it works. So...it does seem that they are right. All those who bought themselves 3rd party adaptors... and have this thing work... they should consider themselves lucky... it seems its not guaranteed.
I chose the adaptor instead of the Samsung Dex Pad (2nd generation) as it is smaller and more versatile. On top of that... it doesnt require power to work... works fine without charger...and... i dont have to remove the flipcase or bumper.

Personally, I'm using 3rd party adaptor and the S-pen works for me...

Does the s-pen remote function have to be enabled?

No

Wireless Android + Chrome Cast in car Now

Most car models produced don’t come with wireless Android Auto functionality. So what do you do if you’ve got an older model, or a new one that doesn’t come with wireless connection built in? This wireless dongle running perfect on my 19' E350.
The benefits I got from AACarPlay
Wireless Android Auto/ CarPlay
Add Chrome Cast to car - allowing watch TV with Car Screen

For sure it's true, before I considered Ottocast which supports wireless AA/ CarPlay, I choose this cause it added ChromeCast that allowing project Videos to Car. It's cool! right?

The screen mirroring feature - are you sure it's "Chromecast" and not "MiraCast"?
I ask because android phones such as Samsung phones support "Miracast", but Google Pixel phones can NOT do "Miracast" - they can only do Chromecast.

That's cool! this means I can cast TV from phone to car display. So how can I do it? connect via lightning cable or Bluthooth?

Your car needs to support Android Auto via a "Wired" connection, then it looks like this gizmo will allow you to connect your phone to your car using "wireless" Android auto. And it looks like it will also allow your car's screen to mirror your phone's display.

I have a question, when it is mirroring the display on your phone, does the car touch screen allow you to interact with your android phone?
Meaning, if your phone is displaying your home screen, and your car's display is also displaying your home screen (via the screen mirror feature), can you tap on an app icon on your cars display (not your phone's display) and have the app launch on your phone, or does the touch-screen on your car display do nothing when in "mirror" mode ?

As you can see on the screen, there're 2 entrances, one is "mirror" and one is "Cast"
Mirror is the entrance that allows you mirror your phone screen to car display, this static, that only show your phone screen on car display.
Cast is that you can project TVs, like YouTube or any streaming media from phone to car display, and you can also tap on icons on cars display to speed or back to home screen.

Does it support all Android apps in cast mode?

The cast mode may supports all video streaming apps, like YouTube, TVs, etc.
If you would like install all Google play stores apps to your car, the aacarplay pro box should be the right one for you! I don't need that much apps so I pickup the standard one, cuz aacarplay pro costs $100 more.

Hi. does wireless android auto work stable? I am looking for another one called AI Box from aacarplay, no limit to down apps.

Can someone test this for me...
Does "wireless" android auto work while the "hotspot" feature is turned on your phone?

Same question!

For the first time setup, keep Bluetooth and phone's hotspot on, after connecting with Android Auto, I can see the the hotspot is off, paired with Bluetooth.
It still using your phone's date while connecting android auto, just keep your Bluetooth on, it will be automatically connected. No need to open phone's hotspot.
