C4(100,A6/S6) Retrofit auto dimm rearview mirror

[Joop]

Hello fellows,

i would like to upgrade my current interior mirror with auto dimm.
I found A8 D2 would be the closest choose.But normally it has a
metal console which i don't belive i can integrate it in C4.


I am interested in your openions.

Get mirror from C5 A6, it's direct fit. Same mirror can be found on B6 and maybe others.

Okey thanks for advice.I will give a try.
Do you think that i can connect the wires of the ceil lamp ?

Yes, C5/B6/B7 will fit. You need to trim the cover piece slightly but it looks OEM when done. You can wire into the roof light, but it's better to go from switched ignition. US models have an integrated compass too - it is completely useless but looks cool

quattro20v (Sean D) on my home forum made that change on his 97 UrS6 sedan. He says:

"I have the compass/auto-dim mirror, its PNP, but need to draw power from the sunroof area. One of easiest and best mods I have done."

unfortunately i don't have sunroof but i guess i can get from the roof light too

IIRC C4 A/S6 has ignition 12v at sunroof. Mirror also has a wire for reverse lights but thats not necessary for basic operation.

you mean it is pre-cabled even there is no sunroof?

No. You posted while I was only writing my post
If you don't want to run a wire to drivers footwell to get ignition 12v, then there's permanent 12v at roof light. Mirror shouldn't be power hungry enough to drain your battery.
