E 34 rear view mirror upgrades
If someone knows which rear view mirrors can be used as an upgrade, I'd appreciate knowing. My E 34 is a 5/95 build and has a nine pin connector in the roof. Currently, I have an auto dim mirror that operates off of three of the nine wires ( I de-pinned the connector), but I have heard that this connector can support more sophisticated mirrors like ones with compass and homelink functions. Anybody know for sure...?
