Jeep hasn't seemed too forthcoming in providing notice of updates, either through the dealer network or via the owners web site. The unofficial MyGig website is a shadow of what it once was in terms of updates. Versions I am aware of are:
2.126 (newest reported version
If it weren't for the generosity of Sox the 2.120, 2.169 and 2.126 updates would be unavailable.
Please post what version your RHR 730N arrived with. Hopefully we will be aware of version changes as they are released in manufacturing, even if we aren't informed of what's new in each version.
My Jeep, built 11/8/11 shipped with 2.116
Updated to 2.126 via update posted.
