Here is someone who installed it.

I am in the process of doing exactly what you are thinking of doing. (I returned the 50-GENK40A and am waiting on the cheaper 50-GENK41A, both include Homelink.)I'm thinking of buying a Gentex rearview mirror to replace the stock one on my 2010 Jetta Sportwagen TDI. It is self dimming and includes Homelink. So far I've found only one local shop that can install them.
Does anybody on the board have experience with this product? Does it work as advertised on your VW?
