If you have a packtalk on the 2020 firmware, you can pair 2 devices via bluetooth. Put your bike on the other bluetooth channel. Sure you'll lose the ability to tether a bluetooth comm into the mesh network but....so then i just do phone to comms, and i still get everything i want except turn by turn on the screen. whatever.
