I got this transmitter for another car a couple months before purchasing this one and loved it. I bought this one for another car thinking it was a great device. What a disappointment, as every 20 minutes or so, the bluetooth disconnects and you hear "waiting for pairing"... This did not happen with my other device, and is not worth even trying anymore. I thought it may be an issue with the phone, car, or the radio frequency; however, the problem persists in all cars, with different phones, on all frequencies.
