iSimple announced that its GateWay iPod and portable media integration system is now compatible with more than 30 model-year-2009 cars and trucks, including ones from Ford, Honda, Hyundai, Lexus, Lincoln/Mercury, Nissan, Pontiac, Toyota and Volkswagen.

iSimple's gadget lets car owners hook an iPod, iPhone or other portable audio source directly into their vehicle's factory-installed entertainment system—which sounds better than a wireless FM transmitter and is static-free. The system also lets users browse the contents of their devices right from their car's built-in display; there's also an optional HD Radio tuner for the thing.

iSimple said in a statement that its products can be purchased at Best Buy, Crutchfield, and other specialty electronics and car audio retailers. There's no word on pricing for the GateWay system yet—and the company recommends a professional installation—although it did post a complete list of compatible vehicles.
