Since you have a Pioneer unit like mine I have a question.
On the drive home was I was running the WAZE app on my phone. I noticed if I had Pandora running, or selected Bluetooth Audio on the Pioneer unit, the WAZE instructions would come out of the car stereo speakers.
However, when I had the Radio or USB selected, the WAZE would not cut into the music and come out over the car stereo speakers.
Is that a limitation of the unit, or do I have some setting wrong?
I need to do a test tonight with making a phone call to my cell phone while I have the different functions up and running on the Pioneer to see what is happening.
