I am soon going to be in possesion of My families old car, a 2005 Mazda 6, with the stock 6-CD changer, and BOSE audio system. I was looking online on how to remove the head unit, because it is completely integrated into the dash! I found a website called metra online, and it has this unit for my specific car, http://www.metraonline.com/part/99-7523S, But when I click to buy it I can't because i don't own a business. So i was wondering where I could possibly find something like this online, or where I could find a kit such as this: http://www.metraonline.com/part/AX-FM01++++++++ to just add an audio jack and ipod dock, toggled by a switch when you want auxillary.
