has anyone installed an aux converter in their car? and if you have, what kind was it and did you run into any problems? i have a ford fusion 06 and i do have the aux button but in need of the input. i have been searching for days for a device and there are so many out there that i dont know what will work for my car and for the touch 2.2. im just confused i guess and in need of some advice on what to do. ive also searched through some car forums but i haven't had much luck with any clear answers. if anyone has experience with this sort of thing please give me ur feedback on what to do. thanks!
