Cable Running To Rear View Mirror

[Alkatraz]

So I have been meaning to ask this for a while. Does anyone know what the cable that plugs into the back of the rear view mirror of my 370gt is for?

Auto tilt for headlight glare? That's what the Euro cars do.

No idea, but I have one to - I have a 350GT Series 2.

Think it's the auto dim mirror you have. My mum lexus has it too.

I had the same question about 4 years ago...pretty sure its immobiliser related...unplug it and see what stops working. I remember unplugging it and something stopped working can't remember what now.

Huh? What could the immobiliser possibly take from a rear mirror? Anyway, the cable in my car does not offer a connector (from roof cavity into the back of the mirror). I could pull the mirror apart I suppose, but then with my luck my brakes might just stop working instead. And I think I need those...

[n15m0]

well I just popped into my garage to confirm this...unplugged it and my intelligent key/immobiliser would not work. Couldn't start the car. So I guess its only for those models who have the intelligent key ie: series 2 v35 and v36. Alkatraz - just unplug it and test my theory.

it is the antenna for the smart key. no antenna = no code = no go.

Thats the scientific translation to my version

Wish my 06 coupe came with one .

[MikhailV87]

I checked my car today and I actually do have this wire. How does one turn on/off the smart key feature?

[Namgun]

sorry for such a noob question but what is this smart key you guys are talking about?? I have an 06 coupe but my key looks pretty standard to me... was the smart key an option?

p.s from my understanding a smart key is like the one in infiniti or E class merc, BMW 7 series etc.... keep the keys in your pocket or inside the car but u can still turn the engine on without plugging the key... am I right??

[MikhailV87]

You are close. From what I understand you can keep the keys in your pocket and when you are close enough to you car you simply open the door (that was locked).

[Alkatraz]

Yeah, car can be opened and started without taking the key out of your pocket. Its pretty cool but takes a little getting used to.

Mine has the cable on the back of the rear view mirror, but I don't have the intelligent key?? Could it also be used for the normal lock/unlock remote?
