I own the original Motorola Bluetooth CarKit and had it professionally installed. I love having the handsfree operation regardless of whether my phone is in my brief case or elsewhere in the car. You can hear incoming voices perfectly but people on the other end complain that there is too much road noise and they have to strain to hear me. In looking at the newest model (Bluetooth Car Kit IHF1000) -- people who own it are still complaining about the same thing.
Can anyone make a recommendation for a bluetooth carkit that DOESN'T have all that background noise for the listener on the other end?
