My 2001 A4 auto-dimming rear view mirror leaked out all it's lcd juice, and no longer auto-dims. What are my options for replacement?

I'm not too keen on buying a used auto-dimming mirror from a B5 in fear that it will fail also. A new one is ~$235.00...ouchie.

I looked at the Gentex brand units but it looks like they are not direct fit.

Does anyone know if the newer B6 auto-dimming with compass are a plug and play installation?

Any other options I should look at?
