the additional idatalink features are actually huge for those of us that have the ability to use them, I was running a Kenwood dnx890hd in my 2011 Mustang with the Maestro rr module, and their MUS1 dash panel with integrated climate controls and OBDII data which was amazing, I just didnt like the Kenwood, so I stepped up to the 8100nex, but I lost the climate controls and OBDII data, which now the 8200 has, Im kinda pissed now! but I couldnt be happier with the 8100nex over the Kenwood, I just dont get all the bitching some members do, the Pioneer is far and away better than any Kenwood offerings imo
