The interior rear view mirror in my wife's V70 is badly streaked internally and getting worse. The coating on the back of the glass is fading and it is almost unusable. I've been looking at mirrors online and there are several options. Most seem to have a series of vertical slots on the left side (rear) along with the other sensor on the right rear. Hers does not have the slots. Are they compatible?

Hers is auto-dimming, has the compass, but not the rain sensor. There are humidity detector options too that I'm not aware her's has.

Even searching by VIN on Volvo parts sites brings up all options.

Confusing.

Thanks,

Erwin
