Yes i have a suggestion, First are you using the stock radio? If you are, they sell ipod interfaces on the net for the cx7 stock radio,Also on U tube look up ipod interface installlation for cx7 and you will get a video of how to install it,Also a local car stereo shop can set you up with one, They are about $150.00 installed,You can also find the interface adapter for ipod on E-Bay, I have a pioneer nav stereo in my cx7 and i installed the ipod adapter but had to get a special two wire cable to make it work correctly, wasnt getting sound just video, a local stereo shop knows what you need they can set you up..
