Hi all, I have the factory stereo, no navigation, etc. To my knowledge, it's bare bones. But like many, would like to get an AUX input unit, or somehow be able to control the iPod/iPhone through the car stereo. Since there's many products that have been out there, was just wanting to do my homework to see what people's best experiences have been? USA Spec? DICE? Trying to stay under $200 if at all possible. Thank you in advance!
