Hi there everyone, I just got the 140bh installed and am driving to use it but all of the functions are greyed out and will not allow me to even use them. IF I go to try and mess with the system settings all grey. If I click the navi button I have no option to enter address bc its all grey. It will allow me to click poi and tune the radio that is it. Any help very frustrated here Thanks.

All the options will be greyed out if you don't have the parking brake wire connected or bypassed properly.
