Just bought my 2015 2500hd 4x4 and i was driving on Friday when the radio screen went black. Has anyone else had this problem. Only 2200 miles. Bought 6 weeks ago
assume you checked for blown fuses, otherwise make an appointment to have it looked at.
On the HID there lots of kits out there.
Just make sure the instructions are carefully followed including disconnecting the battery before doing anything.
