| | Adding cell phone to hands free e39?
I've searched the forum, but can't seem to find info for adding a cell phone to my '98 540. It came with a pre-wired "brick" phone with the hands free setup. Is there any way to adapt the wiring for a newer cell phone? I know that I can use a bluetooth adapter, but that's a bit pricey ($600+). Can anybody point me in the right direction? Thanks.
