Do what centerpunch and I did. Folow that link, take apart your belkin dock and hardwire it adn put a ground loop isolator inline with it. I actually soldered the belkin kit to a ground loop isolator I had, and then put a 1/8" jack on the end of it. I wired the power into the accessory plug underneath the center console. My belkin white cord just comes out of a hole inside the center console armrest area. It's great, pure line-out sound with no noise, and when the car is turned off, the iPod pauses automatically. MUCH cleaner sound than the stock belkin plug/amp thing.
