I have a ProClip mount that fits all W124 models. This clips onto the dash by the center air vents and allows you to mount a cell phone, iPod, or similar device. It clips on in about 30 seconds and won't harm the interior. I bought it but have decided not to use it. It's brand-new and still in the orignial packaging. New it's $30; I am asking $20 including shipping. Please contact me at mcloffs@mac.com if you have any questions. For more information check the ProClip website: http://tinyurl.com/4ce8w
