Mixed. Some owners prefer the Garmin interface while others feel the maps are too "cartooney". Being a lower priced unit the screen resolution is not as sharp as the RER, but overall people are happy with it. Many Jeep owners are awaiting the new RER replacement that's due in January (model RHR). It will continue with the Harmon based nav, but will also have some new and updated features. Too bad they won't be offering the new 8.4" radios in the Jeep, strange that they didn't design ahead for it. I would expect by mid-cycle they will do a dash refresh to allow for the fitment of the larger radios.
who build the new 8.4" units, Harmann?
