Haven't found anyone that attempted to upgrade the software that actually worked. Ya, they had mine for about 10 days. Gave me a 4 cyl. Jeep loaner. Thank God I didn't buy a 4 cyl. Jeep Cares is the best! They helped so much in dealing with the service department. I had other work done (death wobble) and Jeep Cares tech wanted pictures of the repair, talked service through the whole procedure. Can't say enough about Jeep Cares.That was good advice. Took it to the dealer today and same thing happened. They said the update locked up the radio and they were unable to revert it back to the prior software version. New radio ordered - guess I'll be meditating during my drives for the next 10 days.
