Im new to this whole Navi DVD system stuff. All I have done is hooked up the Unit. I havnt messed with the Navi wires such as the brake switch or speed sensor wires yet. But shouldnt the player still play regular CDs? All that works right now is the radio and when I put in a CD or DVD it says "NON-PLAYABLE DISC". Can anyone walk me through the installation process. I dont even know If I have all the right cables. I would also like to hook my Ipod up and be able to play through the AUX but dont know how.

are they original cds or dvds and not copies? the pioneers read "+" format only. try putting in an original dvd and see what happens.
