Whoaaaaa 1999 for the medium line of that unit. I paid $800 and 23 for the harness. I did the install myself. I even jumpered the unit so that I only have to ground the mute wire along with the ebrake wire. You should look on Avic411.com. That site has everything from hacks to installs and map wiring for certain cars. Anyhow I got it all set up and working..
Ooppps forgot to mention I have the f90bt. So its one up on the f900bt. Slightly more powerfuyl, Power amp outputs and ipod cable comes with it.
