Interior auto dimming mirror question

[Mikey4996]

I fitted a auto dimming mirror to my 08 plate vectra a few weeks ago and its brilliant, however it dims with the interior light on and when in reverse.

Is there anything i could do to stop this? As far as im aware the roof loom was out of a preface. Would this be the problem?

Cheers.

You need to us Tech2/Vauxcom/opcom to activate the autodim function. The car needs to know its there so that it doesn't dim in reverse or when the interior light is on.

aright mate.

I've had a look at opcom but cannot find anything to activate it.

But i have looked ay the disscussion for the how 2 and it appears there is 2 different looms, one with 3 wires (which i have) and one with like heaps more.

Just noticed you have fitted one, which loom did you use?

Mikey I take it you ment Vaux-Com as Op-Com cant be talked on here.

Lee genuine opcom units costing £700 can be talked about.

But on some cars.. it just dont want to know that it has rear reading lights.. so cant change that option on some, even that it has rear reading lights, that then dims the mirror (like my car does.. but dont dim when in reverse or with a door open)

I thought it was only people looking for help and support that the admins didn't like about this. I will know for future. Cheers.

Have you programmed the REC to say you have the mirror fitted?

yep.. but on mine also if i turn on the front reading light it still dim..

With the programming tool that i have i cant change that setting or it says "not available"
Edit: my rec knows it have auto dim mirror, but cant tell the car that it has rear reading light/interiur light

Same as mine so looks like i'll just have to leave it the way it is.

Cheers for the help though guys.
