A good idea - I have a heating pad that would do the trick, if I can get it
wedged inside the dash ! ;-)  Seriously, I'll pull out the ash tray and see
if I can't get a good old incandescent light bulb in under the radio.  That
ought to warm things up in a few minutes. Thanks for the idea.

Actually, it probably has (gotten that cold).  You live in NJ, while I live
in VA.  I'm seeing the problem at temperatures above freezing.  A local Sony
factory authorized service shop is completely baffled (based just on my
discussion with them).
