I've copies a large number of MP3's to the card and was hoping to access them in my vehicle. Any suggestions would be appreciated. I am also curious how to update my address book via the card as well. It seems that it is possible, but I'm not sure what format the information on the card needs to be in (eg. vCard, comma, outlook, etc..).
I am having the same problem. My new ML comand with SD slot can't read SD memory cards. I tried with different SD brands, capacity, HC, and the only one that worked is a very old one (1 gb).
I will appreciate if someone know the possible reasons and why it happened. Before this mercedes I owned an AUDI with RNS-E navi system and I never, really never had a problem like this.
