Difference Between 6.1 Navigation System And 7.1 Navigation

[The Big D]

What is the difference between the 6.1 Navigation System and the 7.1 Navigation System ? Is it just a Disk or is there a hardware change as well ?

Aside from the newest mapping, there's a change in the firmware. You no longer have to push the "I Agree" button when you first turn on the Nav. You just get a "Caution" screen for about 5 seconds, and then the map comes up on the display.

Besides the map updates, there are alot of new POI's.

Can you directly update from a Version 2/3 to 7.1????

I think you are confusing the generation (2/3) of your navigation hardware with the most current version (7.1) navigation software.

But the answer would be yes, you can upgrade directly to version 7.1 on your generation 2/3 system (doesn't matter your current software version).
