Like Ive said a few times which may suit your needs I use a Icom 400 or something like that with a remote handpiece,
I ordered a RJ55 patch cord so I could fit the mike nearer the passenger side, By doing this it gives the passenger some imput
instead of just sitting there, allowing you to do what you do best and thats drive, we did this back in 83 going to the Cape have found it the best idea ever.
You could even fit you console patch lead in the A pillar on the Left hand side, worlds your oyster where you want it fitted console patch cords allow a very neat fit. come in heaps of sizes [lengths]
Mine is mounted left of the centre console and moke hangs on 2nd glove box door, just a thought lol
