Avant factory radio

[PeterBergin at aol.com]

Hi guys, any one know much about the stock Audi radio from my Avant (non  
Bose).  It used to have an occasional problem where I had to turn it  off and 
on once or twice before it would work.  Now it seldom turns  on.  Multiple 
turning the off on know sometimes gets it to come on, however  it may shut 
off after some time.
 
The physical abuse method (tapping on it firmly has no affect).  Once  it 
is on, if I turn it off, it will not come on again.
 
I do not really want to invest in a new aftermarket stereo at this point in 
 my Avant's live.
 
Thanks, Pete
