I have the exact same problem.

Looking at the wiring diagram of the serial connector something doesnt
look right with how mine is currently setup. I have the same stick- one
PTT wire and 4 coloured wires going into a canbus and then into the
serial port.

Any ideas?

I heard that the new remote stick doesn't need a sepeate wire for the

best to ask LXNAV.
