Just did a test. As she entered her car the Promate unit said "Connected!". So far so good, as the Promate bluetooth managed to turn itself off when she parked her car in our driveway a couple hours ago. I spoke with her for awhile as she went 50 kph on city streets. She answered my call by saying YES. Road noise at my end was minimal so the noise suppression was good. Volume at my end was good and same for her in the car; the Promate specs have the speaker volume rated at 3w so it should be OK.
