Thanks for the update. Took my jeep to the dealership a couple of days ago and they were unsuccessful, they told me that the updated firmware would stop at 80% and would take a dump.
They later told me that they were going to order another software CD from Chrysler and re-try the upgrade on my Jeep. They also mentioned that if they're still unable to update the firmware that they would need to remove the entire unit (Radio) and send it to Chrysler for repair. In the mean time I would be able to drive my Jeep without a head unit. That seemed to be a little strange.
Oh, well. I decided to take the update you have provided and do the update myself. It worked
, no need to deal with the pesky dealer!
