I just got my canvasworks heatshield for my 2004 Prius. (This is the silver thing that goes behind your windshield to block the sun). The company has templates for all sorts of vehicles, including the 2004 Prius. It's a great fit; perfectly covers the windshield. I highly recommend this product. I bought it for $29.95 from their website (www.canvasworks.com), but I hear you can get it cheaper elsewhere.
