So, I have an older version of P2V+ and wanting to get the newer remote with left dial

Will they work together??

Thanks,

Yes it will.

Dear wayneho000,
Since the old version of remote controller is also 5.8 Ghz. So the newest remote controller could match with old phantom 2 vision +
what's more, we strongly suggest update the hardware to the newest version, the same as Remote controller.
