Stereo & Electronics - Question bout a head unit in 03 truck

I HAVE BEEN DEBATING PUTTING A NEW HEAD UNIT IN MY 03 GMC TRUCK.FROM WHAT I HEARD IS THAT THE ONLY WAY I CAN DO THIS IT TO RELOCATE MY OLD HEAD UNIT SOME WHERE ELESE IN THE TRUCK.MY BUDDY JUST HAD ONE PUT IN ON HIS NEW TAHOE AND THAT IS WHAT THEY DID.WHATS THE DEAL.THANKS :confused:

Do you have factory bose and onstar?

most new GMs have a data serial wire that is in the head unit , it has different functions including driving some of the warning lights , (example: you have use the head unit to turn off the" change oil light" in new Impalas) . Metra now makes an adapter that allows you get rid of the stock head unit. before (especially if the radio said RDS) you had to relocate the old stock unit to retain those functions. the adapter is not cheap but neither was the relocation harness. you can check it out at www.metraonline.

Metra's harness is nice but if you speak to one of their techs they will tell you it is better to keep the factory radio somewhere in the car because certain people have found out that the car will not comunicate right with the diagnostics machine if the car has to go back to the dealership.

Yeah The Truck Has That Rds Shit In It But As Long As I Can Take The Old Unit Out That Is Fine.it Shouldnt Make The Truck Run Shity Or Any Thing Like That If The Stocker Is Replaced Should It. No I Don't have the bose,onstar.Thanks for the 411. :)

If you don't have OnStar or Bose, you can get a Peripheral GMCO adapter and everything will work perfectly.

what if you have Bose?

Not a problem..........just requires a different adapter. The Peripheral part number if you have Bose is GMAH24B.

SO THEN WITH THAT OODAPTER I CAN REMOVE THE FACTORY UNIT ALL TOGATHER

That is correct!!

Thanks For The 411 I Will Have To Check In To That Harness. :) :) DO YOU HAVE THE PN FOR THE HARNESS FOR NON ONSTAR/BOSE
