Useless app unless the bluetooth volume control issue is fixed

I use this app with my iPhone 6+.

When driving, the phone sits in a holder to allow hands-free usage while also being connected to my radio / hands-free system via bluetooth.

Because the phone is connected to my radio via bluetooth, I cannot listen to the radio while listening to the gps instructions. I would have to switch my radio to mp3 mode to listen to the gps instructions, but then I lose the radio. I could disconnect the phone from the bluetooth connection with the radio but then the phone becomes useless in the car.

The previous version of the Tomtom app add the option to disconnect the Tomtom app only from the bluetooth to solve these issues

Please copy-paste this functionality from the previous app on in the new app, otherwise your new app is useless in many-many-many cars in North-America.

The rest of the app works great. It is just this small detail that is missing as a key enabler.
