I cannot figure out how to access the in trunk 6 disc changer from the deck, plus I would like to see what all this stereo has. It's an after market stereo with a stock Honda changer that I'm not sure works because I think the power comes on when you want to use it but i can't figure out how to access it. Please help me, all I need is the manual and I should be able to figure it out from there. Thank you, Steven
