I need to have my navi unit looked at. I installed it the other day, but the unit does not read the navi DVD discs. I am wondering if I have to program the unit or whatnot. This is on a 2005 GMC Sierra which did not come with a navi unit, but the unit should work the vehicle. Its the Delphi touchscreen navi unit.

Thanks in advance.

 

Damn, no one wants to make a few $$$ or help a fellow enthusiast out?

If you do not have a tech2, just chime in with what you know, if anything. So far Im thinking that not too many people have been exposed to this, and then again this is an fbody board not a truck board.

 

no idea what a Tech 2 is, but what is the error it gives you when the disk is inserted?

 

Were are you located i have a tech 2 i'll help you out
