Sorry if this is already answered somewhere else, but I've been searching for weeks!
My dad recently got a 2005 A4 cab and he has the standard radio, but he's wrecking my head to get him an aux input for his iphone! Can anyone help me by telling me where to look/what exactly to look for, or better still, a link. I'd really appreciate the help.
Same thing goes for retro fitting cruise control.
