I would say this depends also to the bluetooth logic in your car. In my car a can select "Audio" (A2DP) or Handfree via Bluetooth, which means that my car will play audio from either selected source. So if i disable A2DP i can still use the phone for telephone functionality, and vice versa. If done so, direction come through the phone speaker. Maybe look for something like that.
I cannot use Copilot with my Bluetooth enabled car if I want to listen to the radio or a cd.
I have another satnav app (Here) which allows me to deactivate Bluetooth within the app but phone calls work fine and I can listen to the radio or cd whilst getting directions through the phone speaker.
Any suggestions as to how I can get around this?
Thanks very much
