2005 Chevy Malibu Base, Stereo Wiring

Hi. I have been searching but cannot find a wiring schematic for my factory radio/CD player in my 2005 Malibu. There is a place for two plugs to go in but only one is being used. I cannot find a wiring diagram for it anywhere. the radio is Delphi electronics systems....Delphi part no. 28000623.......RDO Assembly.....GM Part no. 22734877.........thanks for any info. I attached a pic of the plugs.....large slot is used for factory plug...the small one on the right is not used at all....what is this for??   thank you

CD changer/sat radio port I would imagine.

IF that's what it is....can a changer be purchased after and added and if so would i have to flash the cd player to be able to control it?

I'm not 100% positive because I don't work for GM. But whenever we do sat direct installs all you have to do is supply power for the module and plug it into that port. No flashing of factory radio required. So basically, yes if your CD changer has the same pin-out. But i am not listing an ipod/sat module that will work for that vehicle.

sorry for late thanks...but thank you both for your help one more question... if i wanted to install and aftermarket in-dash CD player...is there a separate component i can purchase that will give me the gas mileage, trip, oil life, and all the other options that i would lose???

Night_1,

check out metra's 99-3303 dash kit, it includes a digital screen that will still allow you to have the features of your factory radio.
