I can not seem to connect to the Pandoara app on the Pioneer NEX 4100 over bluetooth nor connected to USB2 with my Sam S6 Edge. This was the case with both the Android 5 and 5.1 OS on the Samsung. I have the 1.3 Firmware on the NEX 4100. All I get is an error message "Unable to connect, please try again"

 

Android Auto/Google Music works fine while connected to USB2. I am able to play Pandora when executed from my phone over bluetooth but then I lose the capability of navigating the app from the head unit and steering wheel controls.

 

Any suggestions?

Make sure you Pandora app is up to date. If you have not done so, turn the phone off and back on again.

 

Try turning off Android Auto on the phone. I've got problems with Pandora when my iPhone is connected and CarPlay running, so it might be the same type of thing.
