Hello everyone i am new to this website and new to the pontiac i just bought a GTP and i love it but there is alot of cosmetic stuff wrong with it and some of the electronics are not working. I had to replace my radio already. I just put the same one that was in there becuse i want my heads up display to work i love that thing but its still not working right with a new radio. Does anyone know why my heads up display would fad in and out and sometimes never even show up? If anyone could give me some ideas whats going on with my hud that would be great. thanks
