I purchased a car dock for my droid razr. When it was new it connected to my phone and gave a "car dock" screen. However this is no longer working for my phone. I just use the mount to hold the phone, I have not connected the charger or anything. It worked for 2 weeks perfectly, but now nothing...
I have tried a reset of the phone, as well as clearing data on the dock program under applications. I have an HD dock that does still work with the phone.
