Dose anyone here know what the latest update cd is? i just took a trip this weekend and
my nav. kept telling me to turn on roads that were not there.

 

The RB4 NAV system is worse than the worst nav system on the market. Any possible Upgrade CD's, which Chrysler knows nothing about, are made by NAVTEQ, who won't sell them to you, because they only sell thru Chrysler, who gets them from Alpine. Believe me, I went thru all of this already and my RB4 is now a $1500 paper weight, replaced by a real NAV system by Garmin.

05064142AA is apparently the newest.

I read somewhere else (cant recall now) that this is the last disc they will make, no more updates.
