In Reply to: 1993 525iA with no OBC..just a plain clock/date?? posted by Kiser on November 22, 2000 at 14:11:13:
Does anyone know if I can upgrade it to the On Board Computer without any major problems? Can I just buy a OBC and plug it right in to the existing spot or is it more complicated than that?
Thanks in advance,
I was at the BMW dealer last week. I only have the clock, also, but one of the elements is burned out which means it is difficult to tell the difference between a 5 and a 9. The BMW parts man told me that I COULD NOT replace the clock with an OBC; that the car was not wired for it. I would be interested to know if anyone else has better knowledge. Also, I was told that I couldn't fix the bad element and I would have to buy a new clock for $250. That's why I asked about the OBC.
