I have a 1995 Mazda Millenia, and my stereo is flashing error...?

The engine went out a little while ago and when getting it replaced it unplugged the battery of course. It's a Bose stereo. And when getting the car back on the road again it asked for the code, and after three tries it kept blinking "ERR". Does anyone know how to reset it??? PLEASE AND THANKS IN ADVANCE!

I've searched everywhere and don't wanna get slapped by big fees at a dealership!
 
Bummer, well I don't know what to tell ya. There aren't many Millenia owners on this forum so I doubt you'll find anyone with first hand experience of this issue.
