The introduction of Bluetooth to an amateur transceiver will have long-lasting effects on safety, if nothing else. However, in this case there are several drawbacks, and one of those is the requirement to use VOX.
Whether it is mounted on a motorcycle (which it was designed for), or in a convertible sports car (your case), don't expect too much from the Bluetooth in VOX mode. As a wired unit, it is on par with the rest of the Yaesu line.
