I have Rio Nitrus (1.5 GB) and I have been using it a lot lately. I just purchased a FM Transmitter from Best Buy so I can use it in my vehicle. It is pretty cool, but doesn’t work as good as I would expect. You tune your radio to 88.1, 88.3, 88.5, or 88.7 and then set the switch on the transmitter to match. In Saint Cloud, 88.1 is KVSC, so that setting doesn’t work at all. 88.3 also picks up some of KVSC, so that is out too 88.5 and 88.7 work, but crackly. Sometime it works ok, but sometimes it doesn’t. I guess it works good enough to listen to songs. I might need to make a mount for it and the player, so I can get it in a good position and it will stay clear.
