You will need a wiring harness for the model truck you have, plus a filler kit. The filler kit is what the radio will actually attach to and fill the space left by the factory radio. Follow the diagrams for wiring from the harness and the aftermarket radio. Generally, there are 8 wires to be connected for a four speaker system. In addition, you will connect a ground wire (black), a yellow wire (constant power), a red wire (this is to turn the radio on and off with the ignition), and a solid orange wire (illumination). Because you have a GM product you will also need an antenna adapter. All these things can be purchased at Best Buy, or WalMart.

You should check with Car Toys or Best Buy but you will probably need an adaptor and a wiring harness. If your doing it yourself your going to need to know how to get the stock radio out and the wiring diagram for the Aveo. Sometimes you can find the wiring diagram on Google by searching for it but usually finding diagrams for 2008 vehicles takes a year or two before it becomes available.
If your CD player has a tuner in it already you shouldn't need one. If it doesn't have one, that presents some other options.
The wires coming from the radio should be this:
Yellow = 12v constant
Red = Ignition
Black = Ground
White = (Left?) Front +
White w/black stripe = (Left?) Front -
Gray = (Right?) Front +
Gray w/black stripe = (Right?) Front -
Green = (Left?) Rear +
Green w/black stripe = (Left?) Rear -
Purple = (Right?) Rear +
Purple w/black stripe = (Right?) Rear -
Orange = Illumination (DO NOT ATTACH THIS WIRE)
Blue = Power Antenna (only attach if you have a power antenna)
As for going to the chevy, the wires vary by the specific vehicle & I wouldn't want to guess. Also note that if it has a factory amplifier, it'll be a bit harder. I suggest he gets a wiring kit from Circuit City. It's about $15 or so, but well worth it.
