I remember reading the in the manual, that there was a factory fitted optional extra that went up by the courtesy lights in the front headlining. It was basically some buttons that can be programmed to emit a signal that opened electric gates/garages etc.
I don’t have this option

and I did not need it

but now we have had a security gate fitted at work, and they have given us a ‘fob’ but I don’t like extra stuff, so I thought it would be cool if I could use the ‘thing’ to open the works gate…
Trouble is, I can’t remember what the ‘thing’ was called (manual is too far away to fetch to be honest)?
Can it be retrofitted easily, IE will the wiring be behind my blanking plate?
Anyone know what BMW reference number the part was listed as, I have looked on OEM BMW but I cannot find it, I have tried all the obvious routes, but I can’t find it (wish it had a search engine)
