Does anybody know if it's possible to load the 07 Nav/Voice Recognition software into an 08 which is missing commands that an 07 has?

I don't see why it wouldn't work since the hardware would be the same.

There missing commands aren't major, but I know I personally would like to have them back.

I asked my salesman about it, and he said he would consult with the service guys, but who knows when he'll get back to me

 

I doubt it, they wouldn't likely have a code for that in their consult III computer.
