Other apps???
This little dongle can only run
android auto (also claims support for
Apple car play, but I can't test that).
No apps other than
Android auto are supported!
I use Spotify, Waze, and occasionally Google maps, + voice calls via the
android auto wireless interface. No lag whatsoever thus far.
I also tried this the other day, while navigating with Waze, I turned off the GPS on my phone, and navigation continued to work accurately, so I can only presume that
Android Auto uses the cars integrated GPS antenna.
I was pleasantly surprised.
