The unit can remember up to 20 "favorite" songs, and then search all available chancels and play the song when it comes on. 20 favorites isn't really enough for me, and it's annoying to be listening to something and get interrupted to switch to something else. But I did like being able to set up to 18 station presets from the 120 or so channels Sirius offers.
Overall, the KT-SR2000 is a convenient way to get great quality sound wherever you are. It's simple to use and the setup straightforward if you are able to mount the satellite antenna properly. JVC says they will announce a 'boom box' option later this year, which will make the radio truly portable.
