Recently purchased an 08 Elanta, and since I added XM radio, I'm CONSTANTLY changing stations. Honestly, its beginning to hurt my arm a little. My car isn't equipped with with the steering wheel audio controls, but I was wondering how much (or where, or even if) that can be reasonably installed. I looked online fpr kits but didn't see anything. About how much would that be with parts/installation?

Have your local parts guy look in his computer to see if your car is pre-wired for that option. If so, simply buy the parts to convert to wheel audio controls. If the car is NOT pre-wired, it'd be cheaper to trade in your car for one that is equipped the way you want.
