Found the idea with the combined transmitter and receiver function brilliantly. Unfortunately, my unit does not retain the last paired Bluetooth counterpart. In practice this means that, no automatic re-coupling of special cumbersome process of Erstkoppelns must be repeated each time. Is useless so and returns. Unfortunately, not directly from Amazon, but at resellers (lets companies) purchased. Does all the settlement expensive (shipping costs) and more complicated. Happens to me also a second time.
