First off we have the CVA-1000 alpine system control monitor/receiver with navigation input. Then we add the CHA-S614 12-disk cd changer that is controlled from the monitor and now you have the ability to play cds as well as am/fm. Then to top it all off we add the ERA-G320 digital sound field processor and a remote. Every piece of the system is in perfict working order with the exception of the cable that goes between the cd changer and the system control processor. Everything works real good. The monitor controls everything including the EQ. You can control the volume of each speaker and delay how long it takes the sound from each speaker to get to you that way they all reach you at the same time. There is one more upgrade you can do and that is to buy the processor to control the navigation system and that also would be controled from the monitor. I have a cord that will let you play Ps2,DVD,Vcr, or anything thats has a rca jack.It also comes with the Headunit controllor and a headunit cover.I do not have the manuals or digrams for this unit. Any other questions feal free to e-mail me. Ask for 700. Thats what i can get on ebay. All of this stuff is like a 1000 bucks
