How can i get my stereo working?

Hi, I didn't use my '97 Z3 for a while and battery went flat. Just wondered if anyone can tell me the 4digit code. Its a BMW Business RDS, serial # PH7850V1248846. I hope this is right as its very faded. Cheers in advance, Paul.

Try 1903..(Just in case it doesn`t accept a first digit of 7 ...which some radios do not).......If not then ask a new question quoting ALL the SERIAL numbers on the radio casing , especially the MODEL number beginning with 7 *** *** ***

Hi Reg, many thanks for the swift reply. I tried the above code this morning but to no joy.
Cheers for your time. Paul.

I think this is the BLAUPUNKT make so try 7903

Please post back here whether this code was successful or not.(in order to confirm the calculation)
