Its not even a software update. The call Jeep and get a code (I think its like a 13 to 15 digit code) and then go into a service menu and punches in the code which activates the NAV portion.
I saw them do it on Saturday. Wish I watched how to get in to the service menu.
I activated the Nav myself (with dealer supplied code).
See my thread:
Anyone know how to get in and back out of dealer mode?
