It's a 50r/s, but not the firmware, it only uses mesh 2 for now. V1.1 is the latest. The wheel works but only if you disconnect the headset from the phone. The way I do it is use the app if I need to set anything up, but once it's done I seldom need to change anything, can change mesh channel from the buttons if you need to. So the just 'forget this device' then all's good, it's a good unit. I find I need to do this with the 50c and 50r too though.
I also use Chigee with CarPlay.
Just another thing I've found, you can't use the wheel for volume if NAV is selected, it has to be TFT. If I remember right I could with NAV6
