No sound with Google Maps/Navigation using a Droid Razr Maxx HD to a Clarion CX501

I have both soundabout apps, upgraded to pro for greater flexibility and still no sound using Google Maps/Navigation. To my knowledge I have the settings correct. I sometimes hear one direction before the phone and vehicle system sync and that's a maybe. This app can't be that difficult to figure out. Any suggestions would be greatly appreciated. Thanks!

Got it working. I set the media audio to "let app decide" and the audio output to "Bluetooth mono". The only downside is the these settings cause radio volume to go silent, as it acts like an incoming phone call. Once the directions stop radio volume comes back. Not perfect, but better than no sound at all while using Google Navigation.

That's normal.  The only way to quiet the radio in the back ground is if the navigation and radio are from the same source, (when you have built-in navigation and radio in the car).   If you are streaming music from the phone to the car, there is a setting in TTS Behavior to allow the music to keep playing in the background.

Also, that Beta is going to Google play in a few hours.
