Received my 20S on Friday and started to pair them with other 20S's and SMH 10. Did not go on the road to test them but things that I am not satisfied with: The FM Receiver suck (one of the reasons I took the 20 and not the SMH10. What stupid idea that the last unit to pair with moves in the number 1 slot. At the end you will come to the point that the person or unit that you pair the most often with ends up in the last slot and is more difficult to connect with that person. Can you change the software so that the first person you pair with stays in the top position????
