[Android Head-Units] amw2320:
Playing around with my new unit to try and get it configured. I thought I would share what I have done so far and issues I am having.

Root:

I tried creating my own flashable image, but it did not like my 6315_1.zip file, even when signed with SignAPKv2. I was able to decipher my way into 4PDA where a user had submitted a working boot image patched with Magisk (attached). I updated to Magisk 22 from the Magisk Manager after install.

Android Auto:

Three ways to do it.

CarLink (aka ZLink)

This has worked quite well for me, but only supports wired connections. Hopefully they will update soon.

HeadUnit Reloaded

Wireless Android Auto (Note: phone calls not at 100%)

You need to be on the beta version of HUR which supports wireless android auto.

For Joying to support it, you need to change the config.txt build prop to sys.fyt.bluetooth_type=0 (you can flash link below bluetooth0.zip).

Phone calls do not come through the stereo. In HUR I get the error "Bluetooth is not connected." The phone shows an issue with bluetooth connection and says to try rebooting.

I don't know if this is an issue with the unit and it's dodgy BT or if it is the beta version of HUR.

I'm trying others to see what happens with different settings

0 = Wireless AA, unreliable phone over BT

1 = Factory default, no wireless AA

2 = Bluetooth cannot connect to anything

3 = Bluetooth cannot connect to anything

4 = Bluetooth cannot connect to anything

***Potential workaround

Phone seems to work again if bluetooth is turned off then back on. This does not seem to affect AA since it is running through a direct wifi connection at this point.

I have set a tasker task to turn bluetooth off then back on when it sees the wifi direct connection made.

The phone still says "Bluetooth is not connected" during calls, but the

Base HUR settings to not take advantage of this really nice display. I set the following in HUR's graphics settings for a big improvement:

Resolution: 1240x720

DPI: 200

Render surface: SurfaceView.

Android Auto for phones

Looks pretty good. I'd love to be able to use it for other drivers

Problem

Cannot reliably connect to other apps. NPR One and Pandora both say "there is a a problem opening....."

These apps work fine if they are playing before you open.

Adding apps to skipkillapp.prop does not seem to help

Tasker:

Difficulty reading bluetooth connections. May be related to sys.fyt.bluetooth_type above.

Prevent force close when turning car off:

Added net.dinglisch.android.taskerm = -10 to skipkillapp.prop.

Seems to be working. More to come...

Other Issues:

Deletes all google contacts:

Well known issue, remove syncing google contacts under settings -> users -> accounts -> google.

To get contacts back:

Go to contacts.google.com

Select Settings (gear icon in upper right) -> Undo changes

Go back however far you need to when you still had contacts

Recently I reset to factory defaults which killed the ability to connect to google play

Fix found in Joying forums (here).

Download firmware and place on flash drive

Go into app setting and wipe storage for Google Play Services

Immediately plug in firmware USB and let it reinstall

Magically works again after reboot

FytHWOneKey

Doesn't seem to work on this unit. Developer previously mentioned mute button (seperate in other units) was a direct android call which could only be captured with Exposed?
