So Jeep just sent you these out of the blue?! I got my limited in March, haven't received anything?!
I got MY Limited back in September last year, and so far have received a model Willys Jeep with a flash drive on a chain (made to look like dogtags), and another model Willys Jeep with a adhesive button/badge.
Admittedly I had to email them to tell them I hadn't received any welcome gifts after joining JOG.
Maybe this is their way of saying sorry because of the lack of map updates/TMC/App Connectivity for the 6.5" UConnect system.....
