I am an Autocom fan. Still have a Super Pro Avi, and keep spare coiled leads and a spare mike and headset under the seat.
I have tried Bluetooth a couple of times and I have not been convinced. Fiddling around trying to get everything paired up is a pain. It should just do it, but if you then start 'playing' and pairing with other devices, re-establishing the correct configuration can be awkward.
My most recent set up is to have wired rider to pillion. We have music from the Zumo if we want it, and we had rider to rider communication when riding with the club such that we could both take part in the conversation. We had a cheap 'thickphone' connected by Bluetooth for a while and this allows both of us to take part in a conversation if necessary. There was a time when we wanted to be available if members of the family needed help, and this facility was important to us.
Recently I have got a smartphone, and I link that to the Zumo by Bluetooth. That gives data (such as traffic and weather) displayed for the route ahead, provides the same phone link for both of us, the same audio for both of us, and music, if we want it can be controlled from the satnav - either by using the onboard MP3 files, or accessing Spotify on the smartphone - which can be controlled with voice commands. Not that we listen to music much. It can be distracting.
We have just bought a Zumo XT - which doesn't have wired input or output - so we are stuck with Bluetooth for sound from the satnav. I was keen to have sound and phone going to and coming from both rider the and pillion headsets. I was sold a BT device that plugs into the autocom to allow all two way communication between the Autocom and the Zumo. I have yet to test this out.
The inability of any BT headset (that I have researched recently) to allow rider and pillion to communicate with each other and also satnav / music / phone to communicate with both headsets makes them not suitable for our needs, and the wires - they are just part of the ritual of getting onto the motorcycle.
