I have a 04 coupe and am currently using 6.1(?) version of the navigation disc. I plan on updating the disc and to my knowledge the newest version of the disc is 7.3. Does anyone know where I can get one below retail price?

 

you can't go from 6 series to 7 series. I think the latest for you is 6.6

 

members sell them on the marketplace "chicklet" is the name you need

 

you can get it a lot cheaper by PMing vstypicals and ask for v6.6
