hi every one new to the forum ,and i'm wanting to ad the gmx-322 to my '08 nbs d'max it has the rear dvd, nav ,sunroof and power sliding rear window any one install one of these yet? i want it to be able to unlock the nav part and also add the backup cam. I've read ll the posts about adding a back up cam.called gm can get the tailgate bezel in 2 days ,but need to know if i install the cam there can you see the railer hitch? and what cam should i use? thanks for the help. this site has been alot of help already,and there is alot of realy nice and knowledgable people here thanks again

 

Backup cam feature has to be added by the dealer (software upgrade). OE bezel for backup cam on 1500/2500/3500 does not aim at hitch. You will have to either get a fish eye camera or angle your camera for it to view the hitch ball and stinger.

 

ok thanks for the info,i thought if i got the lock pick from coastal tech i could add an aftermarket cam, just want a back up cam so i dont have to back up ,stop, backup ,stop...... you get the idea...also want to unlock nav so i can change destination or poi while driving
