Just a heads up for people living in rural areas - check the Sprint coverage map @ Sprint Coverage
for 3G coverage in your area. You will not be able to activate Uconnect without it.
I purchased a 2014 GC Overland from a dealer 250 miles away (yes, I live in the sticks, and this was the nearest dealer with the configuration I wanted, and a very good price. Too impatient to order). Anyway, fantastic truck, no complaints with the mechanics or the paint, interior, radio, etc. I didn't activate Uconnect while I was there, waiting until I got home.
When I tried to activate it, I got a fatal error with a message about an invalid VIN. When I called Uconnect to work it out, I found out that I am in a Sprint roaming zone, and the nearest native 3G Sprint service area is 2 1/2 hours east of me. I will not be able to activate until I am within a Sprint 3G area.
Now, I haven't yet called the closest dealer (do they really tell customers they have to take a road trip in their brand new vehicle for activation?) so perhaps there is a work around. I will report back.
Hope this info is useful to someone out there
