Having issues getting my LG G5 to work with a Pioneer avh 4100 NEX stereo. I have the phone paired but have been unable to get it to work like it should. Had to change the USB connection several times on the phone. I believe File transfer was what it was on when I was finally able to acknowledge the safety warning on the stereo screen. The connection type defaults back to charging only every time even if I select Always for the connection type. If/when Android Auto home screen does come up, it does not acknowledge anything I touch on the screen i.e. maps, Google music, etc.
I know it is not an issue with the stereo as it worked fine when it was paired with a Verizon Samsung Galaxy S4 and have Pioneer's latest firmware installed on the stereo. I have uninstalled an reinstalled Android Auto from the phone as it was shared from my old phone as well as tried forgetting all cars on the LG G5 and paired it again. Any ideas or suggestions on what to try would be helpful.
