I have my stock one still. It's in a box in the garage wrapped up and works perfectly. $250 and it's yours!

Only removed it for a DD DVD player.
If you get a replacement radio, you'll need the Pac Tato harness to connect to the factory amp and Pac Tato steering wheel adapter to retain your factory steering wheel controls. Both are about $100 each if purchased separately. That's not including the aftermarket radio.
If you purchase both adapters and radio from crutchfield, they offer a discount. It's worth looking into.
