ive been reading various posts for several hours now and havent found an answer, so please dont say "read the posts". several options on my screen are faded out and cant be used. these options used to work, but no longer do. my system settings and gps address are 2 of the ones not working, and yes, i do have my parking brake on. i recently had a rear view cam installed and my stereo guy said he updated my system also, so maybe one of these things caused the problem??? please, anyone know what would be causing this? i dont want to go back to my stereo guy if its a little quick fix i can handle
