Alright, I tried hitting program and "minus" on my HU to see what radio I had. It said "BMW Alipine3".
What's that mean? It's a '94 325i if that helps.
Maybe we should compile a FAQ after we get input from other folks as to their model #s and what their radio readout says...
<span style='color:green'>1994 325i </span>- - - 75,000 mi.
No mods - - - very happy as is!
<span style='color:green'>1995 525i </span>- - - 154,000 mi.
No squeaks or rattles... unreal!
