| Aftermarket Navi Installation Hi everyone, I'm New to the site... I own a 2005 CTS 3.6, Non Bose system, Non navi.
I'm trying to upgrade my audio system. One of the things that I'm doing is, changing my stock head unit and swapping it out for a Pioneer Z1(upgrade z3). I have searched around and found no write-ups on installing aftermarket navi, I've only found the one on cadillacfaq.com on doing the factory Navi.
Know my question is. What harness do I use? Can I use the VW01b Or do I have the buy the really expensive PAC OS-2CTS?
Hopefully you guys understand what im trying to say. |
