I can't believe I'm the only one with this issue. Just bought a Pioneer NEX4100 and I've had my LG for about a month. Its running the latest version of Lollipop. I keep getting incompatible USB. I have tried multiple USB cables (Including the one it came with), I've tried with AA in developer mode. THis is without a doubt one of the MOST frustrating things i have dealt with. Between this and the hoops I had to jump through to get my wife's DA120 to work with Android I'm almost done with Pioneer.
Important Info:
4100NEX firmware rev. 1.08
Android Auto ver. 1.2.084954 (2166577-relea
