Does anyone out there have an extra Navi/GPS antenna that i can purchase?, or does anyone know where i can purchase one besides the dealer? please help.
Thank you.

gmpartsdirect.com or newgmparts.com or Luke at Lindsay Cadillac.

newgmparts has a phone number you can call if you want. Luke at Lindsay Cadillac soetimes has better prices than the online GM parts sites.

Or if you want a used one try Ebay or car-part.com. If looking on carpart try looking under antennas and under GPS navigaion/radio.

I paid $60 shipped for the one for my STS. Got it from a place on carpart.

Thank you, i tried car-part, newgmparts & gmparts but did not find one, i will try luke @ lindsay cadillac and ebay...thanks again, hope i'll find one

Luke will find one for you but they are on newgmparts and on gm parts direct. They have every single part. It is the same catalog as a Cadillac dealer uses.

Its on there you just have to find it. If you get the part number from your dealer you can just put it in. Or you could call newgmparts.

Luke is good too, just saying.
