I'm surprised no one here with their shiny new WK2s haven't been sold this by any of your dealers.
Chrysler DOES offer an On-Star like equivalent.
its called Mopar EVTS (Electronic Vehicle Tracking System). It's Chrysler's OEM lo-jack system that also has a call button to access functions and features similar to the services On-Star offers, only Mopar contacts you through your cell phone instead of the vehicle itself.
It also has online tracking (if a spouse is driving it) and will call up to 3 listed numbers if the vehicle is stolen and driven (or towed) more than 1 mile without the key. Best of all, its transferable to a new vehicle if you buy a new car/sell your old one.
I had this installed in my '11 Wrangler and quite like it, even though I have a droid with GPS, its nice in real SHTF situations.
