I installed auto-radio DEH-P700BT in my car with Brodit support for Iphone
It works well.
But when i am using Navigon and listening Radio Navigation notifications cannot be hear.
It works fine if i select USB source on radio.
In this case ipod music is muted when Navigon notifications are here
I have the same problem after connection Tel and BT Audio through Bluetooth
Radio is only muted when i get a phone call

Any idea ?

Thank you
