For reference here is my other vehicle:
https://yabb.jriver.com/interact/index.php?topic=90991.0I run JRiver on a surface Go straight to amp. I have bluetooth volume/track control for the PC on my steering wheel. I use MO 4Media windows app as the touchscreen interface for MC (on the same tablet). It sounds great and is easy to use.
My new vehicle has USB input and bluetooth. Audio over bluetooth is easy and works well. I can select music on my DAP, the control play, pause, skip track, and volume on the cars interface.
Android Auto (AA) is a whole can of worms that can be summed up by saying JRiver did a great job with their app, but Android Auto is garbage from some sort of dystopian nightmare future.
My Hiby Dap with AA:
I managed to get my Hiby R6 DAP to work. Previously I think my cable was no good. It only works wired which means it will be continuously charged with a non pure sine wave current. It should destroy the non replaceable battery on my 1000 dollar DAP in no time. I do not know why it is wired only, it could be the android 9. i had to install Android Auto, Google, Google Map, And Google text to speech through the play store. The DAP does not have GPS, I was told my new car has no GPS when I specifically asked, yet Google maps works. So my car has GPS tracking. I tried a mock GPS position for multiple reasons which I will mention later. Errors followed, this is forbidden and will not work. JRiver on AA works great, first impression was good. Sadly google has some issues.
The Problem:
I have 500 GB give or take of music on my DAP. When browsing this on AA I can only touch the screen 6 or 7 times before the screen turns black for 7 seconds with a message that says "Safety Pause". This is mental, but OK whatever. But the "feature" that is unforgivable is that when this happens a beep comes through the speakers and the music goes quiet for a few seconds. So to pick a song I need to go through this process a couple times. And in exchange for this privilege I must share my location. If google maps is disabled or mock location is used there is no AA.
Note that you can use side loaded apps in AA. To do this Open AA app on phone/device (which has no app shortcut so does not show in app list), in AA app enable developer options (click version number many times I think), the in AA go to developer options and check unknown sources.
I tried connecting a Samsung tablet with Android 13 and this was a no go. Play store would not allow AA app so I side loaded it. There was some error about unofficial install.
My wife's phone with Android 13 which is not privacy oriented does connect wirelessly. Location and wifi turn on automatically. It also has the 7 tap rule which makes it unbearable to use.
it appears any device that is used has to have the capability of AA build into the OS. There is no side loading the google stuff onto a device.
If there was not a safety pause nightmare one could buy a cheap device like the Hiby 300 and just not put any personal info on it. It would be a good way to get AA functionality without too much privacy invasion.
So I will be using bluetooth, no more AA. I would have been happy with a volume knob and an aux input.
More fun discovered when testing:
I went for a drive to test this stuff. My wife drove while I messed around. We also learned that when the car thinks we are not centered in our lane it also turns down music and beeps, and actually turn the steering wheel automatically. Next weekend will be turning this junk off. Note that we do not have road lines so I do not know what it was using to make its decisions. We drove about an hour each way to a lake. On this drive we saw 3 other vehicles. It is quite normal to not stay centered in your lane, partly because there is no one here, partly for safety. While driving this evening I dodged deer, pot holes, elk, wild horses, and piles of buffalo dropping. While dodging obstacles the car thinks you are falling asleep and starts beeping and telling you to take a break. The theme of the car is lots of beeping and punishments by turning down music.
I do not think I have it in me to install another custom stereo, but it is very temping. The car needs punched in the face. I own it, but it does not seem to understand this.
For anyone wondering how I make phone calls when driving. I don't.
