For some reason today my Starmate 4 cut out and now there is a constant "Acquiring Signal" message. I have tried multiple stations but the message stays on and there is no sound. The weird thing is, the signal indicator shows three bars of signal strength, and when I looked at the signal strength through the menu it showed full strength. I unplugged all of the wires from the car cradle and then plugged everything back in with no success. I then, as much as I didn't want to, restored defaults. Still nothing happened. I have a radio at home, but I won't be able to try until later. Any help will be greatly appreciated.
