Problem with Car Dock and Navigation I just got the Motorola car dock for the Razr Maxx and I'm having a problem with the navigation. I first turned on the navigation and put the phone in the dock, it worked great. Then I took the phone out (with navigation still on) and the next time I put the phone in the dock to use the navigation, the navigation screen was completely blacked out. My husband has the same phone and it did the same exact thing. Any ideas on what could be going on?
