Retrofit F10 LCI Mirrors

I am thinking of retrofitting LCI mirrors, anyone done it?

are the connectors the same?
is it plug and play or is coding needed?

Just wondering how the car knows to send the signal / turn indicator over the LIN bus?

Thanks

I don't see how the connectors could be the same, the old mirror didn't have the signal light.

All the mirror functions in pre-lci work via a bus. there is only one wire which controls all motor functions, heater, LCD dimming, lane change warning, folding. So the blinker is hardly going to be an extra effort. Probably the control module (FRM) which sends the data would have to be different though and perhaps others.
My 2011 F10 has only a three pin connector to the mirror plus a four pin connector for the surround view camera. Three pins = 0v, 12v, bus

My thoughts exactly about all commands being sent over the bus. That is what I assumed. Although this applies to HIGH version mirrors only, LOW version is dumb and the drivers switch directly controls the motors in the that version.

I spoke to the seller of the LCI mirrors and he told me wiring was required to make the turn signal work on PRE-LCI, which surprised me. He sent me a pic and indeed it now has five pins so I was left thinking the extra 2 wires might be for the turn signal.

PRE-LCI
LO uses pins 2,3,4,5,6 (HEATER+, HEATER-, MOTOR, MOTOR, MOTOR)
HI uses pins 4,5,6 (GND, BUS, PWR)

LCI
HI uses pins 4,5,6,7,8

I cannot confirm, but would guess 4,5,6 are as PRE-LCI and 7,8 are now the turn signal.

This is pretty annoying I would have expected the signal to be sent over the bus and the retrofit might be easier then!
