I installed the avic-N1. at least i think thats right. It had the fold out screen and all the options like nav, xm, av inputs, back up camera. well it wasn't too bad the key was to get the rigth parts like the onstar interface module and the correct pocket to hold the unit in the dash with out looking like dunn. I also had to modify there wiring due the onstar module. let me know if I can help.
