Buetooth car kits

Tell me about them.

I know you can get these installed professionally and tied into the radio - that's not what I'm looking for. I'd like a clip-on and glue-on or whatever module with its own speaker that I can just slap on the dash/leave in a cubbyhole/drop on the floor/whatever. Voice dialing and good battery life would be nice. Does this exist? Most of what I've seen either clips onto the sun visor, which looks retarded, or needs a cable to the cig lighter which is worse.

My dad has a pretty good one built in to his rear view mirror.

He finds it pretty handy and most modern phones have voice dial. Hope this helps.
