I installed an android (Bosion maybe) head unit after the stock unit's bluetooth system was being a bit janky.
I have made a video and put it on my youtube channel if you would like to watch it.
The clip goes for just over 31 minutes, however hopefully it helps.
One thing I have noticed, when I turn the dash brightness dial all the way down it cuts power to the radio until I increase the brightness and it turns back on.
It's a handy little feature if I need to reboot the radio, however I'm not sure why it does that.
Anyway link to the vid if you would like to watch:
