I do have the map certificate for my vehicle and the new 2013 usb stick with the map data. When I entered the release code with the usb stick in my vehicle is giving a message telling me the release code is wrong. The release code part number I have is 65902181721. Do I need to get a new code now. I thought this code was an unique alpha numeric code for your vehicle. Can anyone help with this?
thanks
