To control the NEO the click on the SWC is different than for the CDs and radio, the typical CD and radio click is: press, release.... with the NEO to advance once you set the CATEGORY to TRACK is: press, hold, release... you need to hold for a second before releasing, if you hold it to long you will skip 2 or 3 songs. It takes a little practise.
By the way, today I tried the press, hold, release from the SWC before waiting for TRACK to appear next to the time and temperature on the digital display and it worked, but always press, hold, release.
