Has anyone upgraded the Nav unit to the newer one starting in the 07 models? I have an 06 and the nav and unit are ancient looking.

Has anyone done this?

Would you just replace the head unit, or are there other components and wiring too?

Would be nice to do this.

I believe it is everything including the unit under the seat. Others have tried to use updated disc without success, It just gives updated info not updated graphics. I would love to do it too, Let us know how you make out.
