2006-07 NAV system is garbage
By paul brenner on
2007 Jeep Grand Cherokee Limited 4dr SUV (4.7L 8cyl 5A)
Bought a used Jeep Grand Cherokee Limited- under warranty, and the DVD nav system is pretty poor. the maps loaded up from factory doesn't show neighborhoods that have been in use since the 80's, new roads since the 80's, etc. The Dealer update DVD -$200 doesn't guarantee the date of the maps either. The Ebay version - watch out! IF they're selling the original OEM, it still doesn't help. I have the SUV under warranty and the maps are not covered! I can't warn you enough about how poor Chrysler/Jeep did with this arrangement - customer is always cheated -no complete maps when new, $200 update has no guarantees! My $80 Tom Tom surpasses this junk system.
proven wheelbase. if the NAV Support/Downloads were better, I'd really enjoy this SUV.
Update all maps before end of warranty. Make CURRENT maps downloadable from web site - either mopar or ?
