Hello I have a Audio 20 fitted in my new B Class. I was disappointed to see that my iPod Classic 120gb would not behave itself when connected via the MB supplied iPod interface cable. This after 4 years of trouble free operation in an A Class also via a MB After some research I found a compatibility list at http://www.mercedes-benz-mobile.com/ My 120gb Classic iPod and firmware combination is not listed, but the Classic 160gb with firmware 2.0.4 was listed, so I stumped up for a new Classic 160gb iPod, only to find the same problems. And these are as follows: 1. iPod goes 'offline' frequently, particularly at the start of a new track. Audio 20 screen reports 'No device connected' or similar, then it comes back on line after a few seconds. After a while it gos off and does not come back on for 30 minutes or so. 2. The first second or 2 of the first track is not played. 3. Even though an album has been selected, pressing next track just replays the first track. Having said that, this particular fault does seem to be intermittent. 4. Album art does not display on the Audio 20 display. Having stumped up for thr Harman Kardan option and a new iPod I am not happy. Any advice before I try an effect a fix via MB directly. Many thanks in advance.
