Unrelated Audi question;

[Michael Stricker <stricker@ll.mit.edu>]

I installed an alarm in my 4kq this weekend and disconnected the power 
while doing so.  When I reconnected the battery, everything worked fine 
but the radio...a SONY  CDX-4050.  It just flashes when I power it up.  I 
suspect it is part of their theft deterrent system but am not sure.  I 
bought the card from a used car dealer and they don't have any info on 
the radio.  Does anybody have one of these or any suggestions?

Thanks in advance.
