they are all double din radios to they are physically the same size. should be fine in a chevy,
For what it's worth, Crutchfield's website said that my AVIC-Z150BH wouldn't fit in my 2005 Grand Prix.
The "double DIN" refers to the radio opening size. Length and width should be fine, it's depth that may get ya.
The best thing to do is to take your OEM radio out...don't unplug it or you may trigger the Theftlock feature...then measure from the lip of the radio opening in the dash to the closest obstruction. Make sure you allow for cooling, wiring bundles and any adapters you might need for steering wheel controls and whatnot. My Grand Prix has an about 1 1/2 by 6 inch opening between the radio and the side of the dash that goes all the way back to the firewall. I can shove that stuff back as far as the harness will allow me.
Your mileage may vary.
