Anyone know if it is possible to add the bluetooth functionality to my '04 prius? I don't have the nav system or the bluetooth functionality currently. I saw something at coastaletech about a nav enhancement kit that allows a bluetooth cable to be connected that adds the bluetooth functionality. Since I don't have nav this doesn't seem like it will help me. Thanks, Mark
Yep, at this point you might be better off with something like a Motorola HF820; a simple BT speaker/mic that clips to your visor (or anywhere, really) and is available for around 70 bucks. I bought one for my wife and she loves it. She uses the voice dailing feature on her phone to place calls handsfree.
