This interior looks 100x nicer with the NAV unit. Unfortunately my car didn't come with it and I'd like to add it if possible. I have read that I need a pink harness also, for the GPS antenna, correct? Does this need to be routed through the car at all?

I'd also like to be able to use my iPod, I know the iSimple adapter is out there, but could the video inputs in the console also work if an adapter is purchased? I'd prefer not to lose XM.

Lastly, do I need to purchase a NAV unit from an 05-07 STS, or will an 08+ also work?

Anything else I should know? I've seen the YouTube video about the swap and some people had issues after the install.

Thank you in advance.
