Please do report back. I'd like to give this a try. I didn't see anything in here about fixing Zlink not running in the background. This has been my biggest gripe all along. When I put the car in-gear and the front camera display comes on, Zlink stops. Or in the rare case of it continuing to play music, etc., When you manually or it automatically switches back to the Zlink it stops and you have to wait for it to reconnect. This is more than a small nuisance. I use Android Auto to close my garage door, so I cannot just pull out and close the door. I have to wait until it reconnects.
Sorry about that. I had to get that off my chest!
