I saw someone had a post a few months ago on this same topic, but no replies so I want to pose the problem again. I'm new to Droid and have had the Maxx for a few days. Took it on a road trip and used google nav. It worked great, however when bluetooth was connected to my car the voice guidance stopped. Nothing through car audio and nothing out of the phone itself. If I disconnected bluetooth voice prompts came back out of the phone speaker.
