Thanks x2, jrb1.
Does anyone even know for sure where we would look for the update once it's released? Would it be at www.garmin.com/chrysler?
I may try to set up some kind of RSS feed from that page to alert me when it changes. If any of the moderators here have the technical ability to automagically monitor that page and the unofficial mygig site, that would be a big service.
Frankly, I'm not losing sleep over the update, but it does have me intrigued. I probably won't even be in a hurry to install it once it's available. I never apply brand new patches to production machines on my desktop or in my garage.
