Buddy of mine has an '05 sedan and would like to update his navi disc. Which version does he need, 6.7 or 7.4? I know the '06 is the 7.4, but I figured the '05 is the same style and closer looking to the '06 that it would need 7.4.

 

He needs the 6.X discs.

 

Gotcha. Thanks for response. Pretty weird/stupid that they didn't make them all compatible and that only the '06 was different.
