This is not a Genuine GM Part as the title says it is one of the cheep aftermarket mirrors. It also makes an annoying whistling noise as you drive down the road. Its so loud that I can hear it with my windows rolled up. Its bad enough that I'm going to order an actual OEM mirror. This one will end up on eBay or in the trash. The worst part is that I paid an additional $220 to have this painted, so in the end this piece of junk cost me over $300 plus my install time and it was all for nothing. Total waste of money.
