i want to pull the stock 6 disc in my P5....but cant figure it out. I know i need a tool or something from Mazda...but i know of people using other things like coat hangers. There is a few holes after i get the little trim pieces out of the sides, but i dont know which ones do what. if anyone can help it would be great. I want to wire a system i have in my new car but dont want to pay for a bad install job some sketchy car audio place will do. Thanks.
