I'm looking to purchase an android head unit. I've been focusing my attention on the PX5's from joying but open to other options. I've been trying to figure out what issues these units may have and what they are capable of. I've tried to read as much as I could but not I'm not 100% on a few things.
Can an arduino programed as a HID be plugged into them to pass keyboard presses to android? The point of this would be to have external buttons sent to the arduino which would pass those to android as keyboard keys, in the hopes to map them (with tasker?) to move around the interface, skip songs, shortcuts etc. With this plugged in, will this cause any issues with the on screen keyboard.
Can a bluetooth OBD2 adapter and a phone be connected over bluetooth at the same time?
I also have a usb OBD adapter, any reason that wouldn't work?
Any issues with "ok google" working?

I recently bought a bluetooth steering wheel remote control in hopes it would work with my android HU since my truck does not have steering wheel controls.

This particular BT Remote does not work with android HU's, my HU will not even recognize it. When I do a BT search it doesn't appear in the devices section. It connects to my phone and tablet easily, so that tells me that our android HUs are missing a BT profile that allow HID (human interface devices) to connect. Definitely not a limitation of android, the BT profiles were just left out. Unfortunitely I cannot root my Eonon with Android 7.1.2 to solve the problem.
I saw where Car Joying was selling a similar BT controller but it only works with Joying Launcher and a special BT App that I could not get to work on my Eonon.
So beware of these BT controllers for now, until either you can root your HU and install the BT HID profile or the manufactures start adding the profile into the ROMS.
I have the same problem. I ordered with this part directly in China. Can't get it connected to my Isudar radio (link in signature).
Okay, I got root on the device.
Do you have a tip or link what I need to do?
have you tried this app https://play.google.com/store/apps/details?id=com.brachcon.btautopair&hl=en ?

I was able to pair TPMS, keyboard, etc using this method(s)."
maybe in combination with "Modified stock bluetooth app to allow connection to all devices" https://forum.xda-developers.com/showpost.php?p=71280945&postcount=88
Thanks for reply.
Okay i'll give it a try
i have the same bt remote steering wheel....has some user solved the problem? I have the PX5 (GS) with Oreo
tried a lot of BT app of Playstore but nothing ..the "X09" won't connect or is not recognized by the PX5... i'm very disappointed...i don't want install a control box wired to battery.
Chinese law is very different than western law, especially when it comes to goods for export.
They actively and aggressively engage in what western law calls "anti-competitive" practices.
They do this by intentionally disabling devices that are sourced from someone besides themselves, by intentionally mislabelling things, and doing their best to lock you out.
Hi guys
I just bought a Android HU (PX6, Pie, for BMW E90 with 1280x480 display). I'm pretty impressed with the out-of-box functionality and possibilities you gain with this, but there are some little culprits.
I noticed that steering wheel controls (prev/next track) only work in MTC/builtin apps, but I wanted to have them control other media apps like Spotify. Since every attempt I tried through software didn't work (changing MCU settings, key remap apps, mymtcservice, mtce-utils, modify key config files), I was left with waiting till the software solutions get updated for PX6/Pie, or making an own CanBus to USB-HID-converter with an Arduino and others. While i may go that route someday (would love to use the iDrive controller in Android Auto), I found an alternative way/workaround to achieve what I want in the meantime.
What you need is a Creative BT-W2 adapter. It's a standalone bluetooth adapter which gets recognized as a USB audio card and also a HID device, since it supports AVRCP. I'm basically using this device as a AVRCP to USB-HID converter.
First you need to disable USB audio routing in Android developer settings. Then I connected this thing to an USB port of HU, and connected it also through bluetooth with HU. I did need several tries to pair them, since the device somehow doesn't show up in HU bluetooth settings, and it also states "not connected" while it is. After that SWC buttons already started working.
How does it work? SWC next track button pressed -> recognized by MTC bluetooth/music app -> sent through AVRCP to BT-W2 -> emulates USB-HID media key press -> gets recognized by Android system -> gets sent to the media app.
It may be a bit overkill ond also not that cheap, but if you only want working SWC in media apps without fiddling and stuff, this may be a useful way. Probably there are similar devices on Ali which do the same and are cheaper. Together with Automate to autoplay Spotify on boot and Android Auto in standalone mode I finally have a nice integrated Spotify setup in my car, without having to connect my phone.
Hope this helps anyone.

That sounds very interessting, i`m looking for a working "open" BT since long time.
what i don`t understand is, what do you mean by SWC ?
And with what do you control the spotify app then ? you have connected an external hardware ?

I have a Seicane (Chinese-made) head unit with no hardware buttons. It has 2 USB ports that I can use to connect hardware to it. I'm looking for a keyboard/keypad that I can either attach through USB, or connect through Bluetooth to the phone. They already sell round "media" remote controls that connect to the phone through bluetooth. I don't need that because I get media controls already using the steering wheel controls.
I want to be able to navigate android auto without having to touch the screen, so ideally I would like a "d-pad" (up, down, left, right) that connects through USB.
I've looked, and the closest thing I find is a numeric keyboard, it's full size, so fixing it somewhere in the car could be difficult.
Any suggestions? Thanks.
Modify Android 8.1 head unit for better menus & easier BlueT controller compatibility
I bought an iMars 7 from banggood, I believe it’s called a “Android Head Unit AC8227l” but from reading on here it could be a YT9217 or a YT9218 (?)
The menu systems I’ve seen running on these online, on pics or YouTube videos vary. But my menu system is quite clunky and limited.
I can connect a phone via Bluetooth for calls or on-device music controls, but I can not connect any Bluetooth controllers (I’d like a Bluetooth control for music and calls since using a touch screen and driving is a no-no). But I would also like to connect a Bluetooth games controller for my girlfriend to be able to play on it when we’re driving on long journeys.
Also, some better menu controls would be useful as the settings are limited at brightness, WiFi, and a few other minor things. Some display settings, better sound settings, and some others would be really useful.
I havnt wired the radio antenna in because of a lack of a female to female jack, and the reverse camera hasn’t been set up yet so their compatibility isn’t an issue right now!
Is there a way of modifying the software to allow for what I’m after? I’m decent with tech, but rooting an android device (even if that’s the correct terminology) is new to me!
Thank you for any help or advice

Sorry to say, but forget about all your wishes. BT is not available for other devices as phone and OBD.
Modifying the software to get this fixed... good luck...
Hi all,
I have an old school CarPC that I'm looking to refresh with Android Auto. The system in my car has a head unit and a somewhat unintegrated GPS system (separate screen from the headunit, which has no screen at all, only dumb controls). The way it works presently is my CarPC video is tied into the GPS screen and the audio is tied into the headunit Aux input.
You can see some of the details here if itnerested:
CarPC with stock Nav - RX8Club.com
Series I Interior, Audio, and Electronics - CarPC with stock Nav - hey gang.. just picked up an 05 ti grey rx-8 a few weeks ago, came with the full GT package, MS front and rear spoiler. still have the rear and side skirts to go. in the meantime, i decided to get going on the interior, adding a...

What I'm looking for really is any hardware device that:
1) can run Android Auto
2) outputs video to VGA
2) accepts a USB controller for capacitive touch screen
3) accepts a USB controller for Car2PC/Aux input -- devices like these allow a standard audio jack plug into the Aux port, and then ALSO enables steering controls to work (volume, next/previous track, voice control prompt)
4) accepts a standard jack microphone
5) not critical but ideally accepts a radio antenna to integrate OTA radio signal into Android Auto
I *think* raspberry PI is my best option at this point, but it seems like it doesn't have all of the kinks worked out as of yet. If there is something I could install on the bare metal of my car PC, I think that'd be most ideal.
I'll appreciate any expertise on this!
