Hi All,

I have a 2003 Tahoe with a Non Lux Sound System ( which I think is correct as my truck does not have the Y91 or Y92 option although the speakers says Bose on them) I have bought recently the navigation non lux head unit with the GPS antenna and the version 3.0 DVD disk. The problem I am facing is that when I insert the DVD Nav disk the system starts up fine but after about 30 seconds the system restart by itself it shows the Chevrolet Logo and goes back to the navigation point, this happens regularly every 30 seconds also same happens when I try to enter a destination every time I press to enter the destination it restarts again, but when I dont use the DVD disk the system works fine even when I insert a CD I can listen to music no problem. Any suggestions, I will appreciate any help I can get on this matter.
Thanks
