I heard from ToyotaNation that there is a guy who sells Auto-Dimming Mirrors with a homing device and compass on EBay. His name is WembleySells and he can be found through ebay or at his website, . He is willing to do "group buy" at a group rate if enough people are interested in buying them. Check them out on his page on EBay and let me know. They're already at a good price, but what would it hurt to try to get it at an even better deal? He also does them for Honda's, Nissan's, Mistubishi, etc..
