I just got off the phone with Bose tech support. They say that they have a known software problem with the V20 in software level 01.01.02 and are working on a fix which will be available at some unspecified future time!

You can get the current software level for your V20 by:

1. Shut off the Bose
2. Hold the center button on top of the display down until "House Code" is showing.
3. While holding the center button down, keep pressing the on/off (leftmost) button until the software level shows on the display.
