I have a 2011 Mazda 2 Touring and I was just wondering if there are any products that would allow me to use the steering wheel audio controls to navigate through my iPod? Maybe like and ipod interface or a USB port that I could add on to the factory radio. Also, I was wondering if there is any way to add satellite radio to my factory radio without having to use one of those aftermarket ones that mount to the windshield with a suction cup. Does anyone know if these products exist for the Mazda 2? Thanks.
