I bought a hands free kit for my Yaesu FT7800 in my Volvo.
Very simple to install, it just plugs into the Microphone socket and replaces the fist mic.
It has a Microphone which clips on to the sun visor, and a ptt swtich, which I’ve cable tied to the gear stick.
It’s surprising just how much easier driving is with both hands while operating the radio..
