If the current unit is a Harmony, it will have a BMW connector. If it is a Symphony, it will have ISO connectors.

You can see in the picture of the BMW to ISO adapter lead, there are 3 connections missing in the ISO power connector, two are for the steering wheel controls, (which can be retrofitted) the other is for the phone mute, which would not be needed.
