   Back in the olden days, pre-Bluetooth, there were hands-free car kits   
   that had to be wired into the vehicles, complete with an antenna on the   
   outside of the car, a separate speaker, and a separate microphone. There   
   were different "cups" to fit different phones.   
      
   I put a Motorola one into one of my vehicles. This was back in the days   
   of AMPS analog phones and the range was very good and the coverage was   
   excellent. There was no amplifier but one wasn't really needed with the   
   external antenna (but you could buy a 3 watt amplifier). I kind of   
   became the source for information about the various Motorola models of   
   these systems and had a web site about them, that's actually still up   
   .
