I am now watching this thread with more interest than before. My Impreza got destroyed this past Saturday morning by another car whose driver didn't notice his red light until wayyyyyyyyy too late.

I've retrieved the empeg from it, but fitting it into the latest vehicles looks much more difficult than it was in the 2013 Impreza.

It's likely to end up under a seat, and having a BT connection might make it easier to access for the driver -- passenger can of course just use the Android empeg app from a smartphone.

EDIT: Say.. I wonder if "Android Auto" can run/display the empeg app on the in-car display?

Cheers
