I bought my Rubi in late June 2011. It was on the dealer showroom floor and it had everything I wanted. I LOVE IT. My "significant other" bought a 70th Anniversary Jeep Grand Cherokee from the same dealer a month later. It has the same 430N Navigation/Media center.
I noticed that the 430N in the slightly newer jeep worked better. Also it had something called Sirius Travel Link. Mine did not. I researched this on line at Jeep.Com and found out that the early jeeps made before mid 2011 needed a software update to the 430N system. There were TWO updates. One to update the 430N system, and another update to load the Serious Travel Link SOFT KEY. I was subscribed to the Serious Travel Link, but was not getting it because my software was bad from the factory.
Travel Link does the following things:
->Satelite Weather Update where you are or where you are going
->Nearest Gas Stations sorted by PRICE and Distance
->Nearest Movie Showtimes
->Local Sports Scores
->Nearest Ski Conditions
I know - this is unmanly jeep extras, but it is kind of cool, and you paid for it.
If you have an early 2011 Jeep with a 430N. check this out. ALSO there is a separate Jeep Owners Manual for the 430N or 730N systems. This is how I realized there was something missing on my Jeep.
I took it back to my dealer, and they had never heard of this issue. They said no one ever returned their Jeeps to get the upgraded software. They took care of it for me, and it works now!! I like all the features! It is nice to be able to check local movie schedules when you are off roading and knee deep in MUD!
