this product worked very well for me in my jeep. it did take me a couple trys to splice it into the right wire, but it did work when i spliced the fuse wire into the main power wire on the back of my CD player with the fuse on it too. i also had to make the AUX function capable on my headunit by holding in some buttons while it was off. i had the guys at my local car audio store help me. they just told me what buttons to push, i didnt have to pay them to do it. i would recomend to get the adapter to charge your ipod as well though too.
