I am considering a bluetooth receiver for my car. Right now I'm using a cable but that is annoying and gives the car a cluttered look. I looked on Amazon and the Mpow seems very popular and well rated. The only negative I could find is that it does not automatically turn on and pair when the power comes on (car starts providing power via usb). I would have to push the "on" or "pair" button I guess. It is very inexpensive but before I buy I'd like to know if there is something better. Let me know what you use. Thanks!
