Blue Tooth and Google Map Commands

[ADKDogwalker]

When I use my iPhone 6 with the Jabra Freeway Bluetooth hands free device in my car it works wonderfully well with music and phone calls. However, navigation commands from Google maps are treated as a phone call. After each command, it announces "Call ended" and if I am on a phone call, it hangs up.

Any way to either:

1. Get the navigation commands to be treated like the music coming from my phone instead of as a phone call;
or
2. Turn off Blue tooth for Google maps navigation only while still using it for phone and music.

Thanks for any suggestions. Jabra was of no assistance whatsoever.
