Hey all,

Got an 05 SUT with the OEM NAV system installed. Tried it for the first time tonight in Calgary, AB and noticed that the system needs some serious updating. Will newer system disks work with older NAV systems ??

Is the Canadian sold trucks sold with different NAV disks than USA ?? Has anyone encountered this problem before ??

Thanks

 

The Nav discs are the same for all of North America.

Which Nav do you have and what is the VERSION of Map Disc???
