Same issue here, Installed the WW-BT VC-V2 and like Wylie said, the pairing of 2 wont work. I did notice there are 2 un-used connection ports on the back of the Supreme Control Screen, I've been searching for information on what those could be, Really disappointing that there is no Aux or USB connection option on the Supreme Control device. I agree, having to navigate screens wile towing or even moving is a pain in the A** everything else on my boat is outstanding, seems like they thought of everything just not this issue.
