When my system comes on and i hit phone, settings or navigation I can see the buttons but I am not physically able to hit them to get taken to the next screen. I can see that the options are there, but I am not able to set my phone up or even change the settings of the navigation system. Please help! I bought this car used and this unit was in there, so I am very unfamiliar with it. Its happening with the address book for navi, and all the phone options.

Pull the parking brake.

or do the bypass
