Another newbie here...
I just got a 1995 540i a month ago. It has a hands free phone system installed in it. The phone is missing. I was wondering how I could tell whether it is a BMW integrated system or some other aftermarket system?
Just as you mentioned, I'd like to get the integrated system in my car (if it is indeed the BMW system) to work with my digital phone.
I can't be certain, but it looks like the system in my car was designed to work with some sort of Nokia phone. In fact, some of the hands free kits at www.connects2.com look similar to the one in my car. I've not been able to find a picture of the BMW system.
In any case, the Nokia phone I have now (3100) is way to small for the cradle and none of the plugs match. I was hoping that I'd just have to replace the cradle and everything else would work. But from other messages I've seen on the web (www.expansys.com, et. al.) it looks like there are some voltage differences, too. It seems that there is some sort of control unit that would have to be replaced also.
BTW: what functions does the integrated BMW phone system have?
Thanks!
