Have a factory radio and took it to the dealership to get the code but they cannot find the S/N on the radio. It is from a 1992 318I. The only numbers found on the radio are KE-92zbm, Made in Japan. On the metal case it has inscribed PI 92xx C OO29279 (Bottom portion of the metal case) and in the back (net to where the antenna goes on) it has 1147-1 inscribed on the case. On front it say's BMW Bavaria C Business RDS. Any help would be appreciated! The easy way out would be to buy another radio but I'm trying to keep it as stock as possible.
You can't break what's broken you can only fix it!!!
