Hello,
I purchased an AVH-P8400bh a few months ago. So far, I'm really happy with it. However, I primarily bought it to use with an app called 'Waze' which works pretty well with the unit.
My only question is: when I switch the radio to appmode so I can use waze, it stops playing the music from XM or FM. Is there a way to switch to appmode, but continue listening to the XM radio? Have I just not stumbled across it yet?
