GTA Car Kits Honda-Accord-2003-2007-iphone-kit AUX and iPhone Car Kit for Honda Accord 2003-2007
I used the kit from GTA Car Kits. It was about $100 from them and then I had to order an adapter from apple to use with my iphone 5. All said and done about $160 but now I can use the car's audio controls to adjust volume and skip tracks etc. It only took about 30 minutes to install too; simple plug and play. I could have gotten a new deck for a little bit more money but I love the stock look. Be careful before you order though. Honda randomly installed 2 different types of stereos in the AP2. If yours is like mine (XM radio capability) you have to order the kit for the '03 accord.
