New NAV DVD Instal
 

In the last month I received 2 separate shipment of new discs for my navigation system. Very nice that they give you these free. The rub here is that they are not identical. They each have different part numbers and map numbers on them. When I called my local dealer they said I would have to bring them in to tell me which one is the most current version. That seems a little dumb to me, but that would not be the first time I have thought that with this dealer. Any help out there?

Also, It appears to me that there is no separate navigation DVD drive as I had in my Acura. Do I just insert these into the CD slot opening?
