Deck was installed today by a reputable installer.

Once I arrived home I activated the Sat radio and then wanted to get into the setting to make some changes. I'm not able to access any of the menus - not for the Nav, BT or Audio.

Am I correct in my thinking that they may have made an error and that the deck isn't seeing the truck in park?

Vehicle in question is a 2008 GMC Sierra.

Any input is appreciated.

Thanks.

very good chances the installer did not hook up the Parking Brake properly

and that is whats going on

first thing in the AM i would call and notify them or better yet drive there and let them know you think they did not hook it up properly that way they cant tell you on the phone they have no time now

Problem solved.

I was correct in my assumption.

I tore that apart and decided to do the bypass while I was in there. Everything is working now!

So far I like it!

i would still call the shop and let them know what was going on maybe they should refund some of your install labor cost since they only did part of the job

did they not hook it up at all, or did they hook it up to the actual parking brake, and you just were not setting the brake?

wow that a pretty big epic fail since almost all parking brakes only have one wire coming off of them.
