Re: RER software update to 2.402 (Fixed iphone issues)
Yes...There is a certain sequence you have to follow in order to upgrade...some versions cannot jump to others without an incremental update. This website is your friend:
According the site:
NOTE: You do not need to install these updates in sequence. One update completely replaces your version.
I'm a bit confused though. Why does the version go from 9.807 to 1.220? My '08 Grand Cherokee appears to be running 9.713 (which the dealer supposedly upgraded it to in August), should I be moving to 9.807 or to 2.402? Thanks!
