Ok, so, got the nav radio in and programmed to the truck, put an OEM gps antenna in and that works. Since the radio was unlocked and programmed to my truck, the clock did'nt show. I found after googling it a hidden menu and the code to open it. I was able to get the clock to show. The only thing left now is the CD/DVD player (map reader is fine) won't read any disks music or movies. So either I have a bad drive or something else. Now, when I was in the hidden menu, it had an item listed as DVD reset. I don't know if that is for the map reader or the DVD/CD player? Anyone know and can give me some advice?
