Does anyone use Google Maps as a Car GPS? I do so and also have my Iphone 5 connected to my bluetooth car kit to answer and make calls. The problem I face is if my IP5 Bluetooth is on and connected to my car speakerphone unit, every single voice instructions will be annouced via my car speakerphone unit. this means I cannot get to enjoy listen to the radio or music on my car system. Is there a way to make Google Maps or IOS6 make app sounds go through the IP5 speaker via continue to allow the phone system to work via bluetooth?
