We've been scheduled to get yet another refurb 730N media center because satellite presets continue to disappear on ours, even though it has firmware v2.120.
However, our dealer called today after speaking with Chrysler. They won't be sending the radio after all because they (Jeep) insist they will be releasing a TSB with a "software solution" specifically covering disappearing satellite presets on the 730N. ETA not yet nailed down, but they're currently estimating 2-5 weeks.
No further details, but it would seem that this would be either a dealer-installed patch to v2.120 or elsewhere in the Jeep system, or a new firmware version altogether. As we've heard nothing about this from Sox and his contacts at Harmon Becker, which issues firmware updates, odds are it'll be a Jeep-centric patch unless Harmon Becker issues new 730N firmware very shortly. (Harmon Becker issues new firmware weeks before Jeep gets around to making it available.) However, if it is new firmware there is reason to believe it will have a number of fixes and enhancements.
I'll believe this when I see it through the mists and vapor . . . and whether it actually does what it's supposed to!
