Hello, I finally discovered a reasonable way to get the old Comand to play MP3s. You can refer to the “Mercedes Player 040” here: www.mercedes-player.com The player is simply connected instead of the CD changer. It is equipped with 2 SD and 2 Compact Flash card slots each, in which you can plug all cards, also and especially cards with high capacity. The operation is extremely easy – the player holds every card slot for a CD, so that the complete operating functions of Comand and steering wheel keys are completely preserved. The attached images show how the device looks like in the built-in condition – for the sake of simplicity it was simply fixed with Velcro tape on the CD-Wechlser, the cables were removed from the CD-changer and then plugged back into the Mercedes-Player (one needs patience and slim fingers, if one does not want to expand the changer!): Advantages: Extremely good sound quality, overhaup t no comparison to the futzel with FM transmitters. Also an iPod connected via dock connection to the AUX socket in the glove compartment cannot keep up. With the Mercedes player the thing is again really fun because of the comparatively really good sound. Vibration-insensitive – no more dropouts on bad roads. Uncanny fast track, folder and media changes. Disadvantage: No display of the contents of the ID tags, however not the Mercedes-Play It’s his fault, but the comand, logically. The costs are really within the scope with approx. 230 euros, especially if you look at the alternatives on the market. I bought the device directly from the manufacturer, who was extremely hard-working and helpful, even helped with the installation and that even on the Pentecost weekend – hat off. Previously we had 4 gigs and 8 gig SD-High Capacity cards to report no problems.
