i bought this ipod adapter and connected it to my pioneer deh-p2900 mp and it works great. I was hesitant to buy at first but took a shot and it payed off . It was extremely easy to install the hardest part was taking off the radio. To install it all you have to do is find the power and the ground which is labeled and tape it up. I plan on buying a cd changer in the future to connect to the free ip bus port.
