my friend you are one lucky guy..u have a GT..assuming you don't have any premium sound system which i tink you DON'T..head over to wal-mart pick up some for 6-8bucks..or go to circuit city, bestbuy, or any stereo shop near you..they all have them for 10 and above..or get them online at crutchfield.com they have it and it comes with instruction on how to install, which you don't really need because it's very basic to install..oh yeah if you gonna get harness you might as well get the installation kit, or the double DIN..get them at crutchfield.com it's 5 extra to have them shipped, I think..check them out or call, or call around local stereo shop to get an estimate on prices..
