Hi Rog, Agree dump Avast as it's been not much good since ver 4.also try getting hold of SD Jukebox ver 5 This has non of the limits to the number of transfers back and for to the SD card also you can edit some of the sound effects such as reverb and surround sound simulation. I have found it works very well with the KN7 even as it was set to work with Panasonic's SD type of IPod,and it is much easier to use than the one supplied for the KN7000 I believe ver 2.4
One bonus is that it works with any type of SD card reader.

Best regards John.

PS. this version also will export WAV. files to the KN without prior need to convert to MP3
