dshogman and Rick Coleman:
I checked on the coach today in its storage location and foudn the model numbers on the Sony DVD Home Theatre, is that it's called exactly that -- a Sony DVD Home Theatre, model # DAV DX-150.
For what it's worth, that's what WRV replaced my Kenwood with, and it works well, other than the fact the controls are on the top of the faceplate which sometimes requires me to stand on the driver's seat to see what each button says (because I am short). But the remote control for it works seems to to work reasonably well. At least it stays in place, doesn't smoke, smell, or fail to work for me.
