I would also make sure that they disclose upfront that you will loose about 40-50% of sound volume from your ipod. I just had my ipod kit installed on slk 55 and I just took it back to the dealer when I noticed the major difference in volume between the ipod and the radio and cd player. It was very upsetting having spent about $900 to get this extra for the crapy sound quality!!!

Hope this helps you!!!
