If you have the small blue plug on the back of the radio (or the port is empty on the radio but will accept it-most likely the case with what you have described), you could use a Peripheral plug-n-play harness and auxilary box similar to the ones above. It will allow full seamless stereo sound integration through the factory system. If you are mechanically inclined, you can do this project for under $100 in parts. We do lots of this type integration and it sounds tons better than FM Modulation (that is a last resort if no plug-n-play options are available).
