I have a 2006 LC. I'm thinking of buying the BT35-TOY Bluetooth to stream music mainly. The vehicle already has handsfree calling of course, so do I have to install the mic that comes with it? I would think not since I already have HF calling stock. I assume that I can hook it up to the sat radio spot in the back of the unit. Sorry to start a thread on this, but I couldn't find anything about the mic hookup anywhere. I don't want to mess with it if I don't have to.
