ljd51 Posted July 30, 2010 Report Share Posted July 30, 2010 I had an x920BT installed by a local shop with no apparent problems and the unit works fine except the screen does not dim at night. I have the Day/Night Display set to Automatic but the screen never changes; it's always bright. The installer says it's because the car's CAN doesn't use 12v power to the auto dim functions. Suggestions welcome. Quote Link to post Share on other sites
