Help Bluetooth problem

[MAK37]

Hello, I'm new to the forum and need some help. When my wife's F3 (Virgin Mobile) connects with her car GPS/radio it connects as both a phone and media device, even when the "Media audio" selection in the bluetooth settings is unchecked for that vehicle. Anyone have any ideas about how to make it connect only as a phone?

Thanks
