Will Pay For Info Delphi Nav Install

I Have An 04 Silverado Ss That Came Stock With The Six Disk Indash Dose Unit With The Amp And Sub Junk.....anyway Decided To Add The Nav Unit That Comes In Denalis And Caddi....installed Umit Today. All Nav Fetures Work Great Voice Promts And Stuff ....but There Is No Other Audio ...cd,xm,fm If Anyone Has Successfully Completed This Install Please Reply ....i Would Even Be Willing To Pay For This Info

Thanks,
Dave

well, i know this sounds stupid but did you plug the speakers into the unit? this kind of stuff is the reason why i get pros to do all that..if i do stuff like that i screw it up and have no idea whats wrong...in other words take it to a pro..if you had a pro install it take it back to them yell at them and demand they fix it for free

without looking at it i can not give you a good assesment.
I would say you do have the speakers hooked up or you could not hear the nav.
There must be a data or audio cable to the other components. Are you getting the menues for the xm etc. or not?
If so there is an audio cable/ link somewhere not connected properly.
