I have a 2005 Prius that has bluetooth capability and I am looking for a compatible FM transmitter or car adapter. I used to have a very inexpensive cassette adapter that worked beautfiully with my ipod and does not work at all with the iphone. I tried to other products over the weekend with no success. I suspect that I will get the airplane mode notification and it will still work (did with my logitech stereo system) so that's fine. One of the products I tried played through the radio ok, but did not allow for the bluetooth to take calls. I have a very long commute and I NEED to be able to use it in the car.
