How to replace side mirror?

someone hit my 01' tiburon and broke my side mirror... i'm a novice and am not sure how to go about replacing it. what should I do? goto a junk yard and get another mirror, or get the whole assembly? how do you pop out the old one and pop in the new one??

If you go to the Hyundai Webtech site you can choose your model from the menu and be able to view the Shop and Electrical manuals on line. The instructions would be available there. I believe if you go to the dealership it would probably cost you more than getting the piece at the Auto shops/Junk yards.

to get the whole thing off, i think all you need to do is pop off that triangular peice inside. there should prolly be something there.
