I think I may know what your problem is... Sometimes when the cars arrived at the dealerships, they opted to install the navigation on site. If they did, chances are, they did not wire it properly because the instructions that are provided to the technicians are incorrect. Please tell me exactly what is happening with your unit. Can you input the destination and then it just doesn't recognize where the unit is? Does it show a road that is completely incorrect and will not recalculate as you drive?
