[A4] Auto-dim mirror not workin

[Jonathan]

Hi,

Had to have my windscreen replaced recently. Asked the guy why he had a bbench 
grinder in his car, apparantly in their industry, it is common for the rear 
vission mirrors to come off with a huge chunk of glass attached. So... be 
careful!

Just out of curiousity, are the auto dim rearvision mirrors on Audi's any 
good? The only one I've used is on a Subaru forrester, and like everything 
else I've found on Subaru's it was completely terrible!

Cheers

Jon
