Yeah I don't know about that. I am running off my limited memory at best but I will say with a collected amount of mind power we should be ok but I will try my best.
Hand helds will be fine. There were some guys last time that had them.
Just being able to have some decent communication between vehicles, other than flashing lights and horns, is good to have.
I would say that lets save the horns for stops in a 911 situation or a mechanical failure.
By the way, anyone going know how to do the zero point cal on 4th gens?
I sure could use one.
