my dad has had a similar problem with his truck. If he is listening to the radio the truck wont pass the nav app's instructions from the phone to the stereo. This is because the truck treats the nav app the same as it treats streamed music from the phone. If he was listening to music stored on his phone instead of the radio he'd get the nav voice over.
I think i explained that kind of clumsily.
edit: basically the stereo treats the bluetooth signal as either Phonecalls, which overrides everything, and Media, which it will only play if you've told the stereo to use your phone as the current media source.
