I just purchased a used 2005 Honda Accord EX V6 Sedan and the Navi DVD was missing, I really don't want to pay the $191.00 + tax asking price. What versions of the Navi DVD's will work on my vehicle? I have a friend who owns a car salvage yard with several 05 Accords, but the Navi DVD's are all different, what version's will work on my Navi system? Thank You for your help it is much appreciated.
