I'm curious if this is possible in my VW Tiguan:
Listen to AM Radio
iPhone connected to bluetooth of the Tiguan
Apple Map Navigation running and audio from the iPhone interrupts the AM Radio from the Bluetooth connection.

I can't seem to find a way to make this happen.

Alternatively, is it possible to only connect the phone connection for the iPhone but the Audio (non-phone) component not connected. Therefore, phone calls are routed through the VW, but non-phone calls (Apple Map Navigation) comes through the iPhone speaker.

Any help would be greatly appreciated.

Thank you!
