Radio problems

[Levolorman at aol.com]

I'm new to this, so...
 
Anyway, my daughter just received a 1991 200 Quattro Turbo Wagon as a gift  
(from her Grand Aunt).  The car is pretty good for 165,000 miles, with the  
noticeable exception of the radio (which is currently worthless).
 
I've been told that the radio is rather special, and that either the car  
must be totally rewired for new speakers and radio, or the original radio should  
be replaced with original equipment.
 
I have an acquaintance who works for a local VW dealership that tried to  
order the radio, however, says it's no longer available.
 
Anybody know what the truth is and how I can hep her rectify this  problem?
 
Thanks
