upgrading to navigation questions

mattsworld · #1 (**permalink**) 06-24-08, 07:33 PM

I am contemplating just buying a navigation unit and replacing my stock radio. What all would that include me doing as far as the install? Would it use my existing onstar antenna(it's mounted on the hood)? And would all the information still be displayed on the new unit?

You need to splice in one wire for the VSS, and add a gps antenna. The rest is plug and play, after you get the theftlock cleared from a dealer.

It's pretty easy once you get the hang of prying off plastic bezels and if you know how to use wire taps.

easy = yes, expensive = yes, i want factory nav something awful, but cant imagine spending that kinda cash for it

It's worth $1000, if you like navigation. If you rarely travel to new locations, I wouldn't bother making the purchase.

Be careful what you wish for.

There are much better systems that are easier to use.

Installation is a bitch though.

well carputer is on the list, but the price of it versus navi is roughly the same with less work.

ive got a gps unit i use, but tired of it and my radar detector on my dash, need to install my xm radio and kinda want it on the dash, but jeez three things in the window....

Hi everyone.

know my question is, What if your upgrading you non navigation CTS to and aftermarket Navi like Pioneer. What harness do you use? can you use the VW01B? Or do u have to buy that very expencive (PAC OS-2CTS)?

everything ive read you have to use the Pac harness

Not to steal your thread, but I recently purchased a used 05 CTS-V which previously had the navigation system and 6 disc, it now has just the single disc. I was wondering how much work would be involved in swapping the navigation back in there? All the wires and everything should be there no?
