So I have a 16GB SDHC Card and when I use the car on my C300 on each folder each song is duplicated and will only function the 2dn copy... so if I have 10 songs on a folder the car will make 2 copies and it will start skipping songs 1.2.3.4.5.6.7.8..9.10 and only when it gets to 11 it will start playing I have tried formatting the card but I still have the same problem....

 

Very odd. I just bought a 16GB SDHC from eBay, and I haven't had that issue. How many songs do you have on there? Maybe try just putting a few and see if it's that? I haven't really had time to load mine up, so I only have like 100 songs, and I haven't had any issues. You know anyone else with a C-Class? maybe you can figure out if it's your car or the card that way...good luck.

 

Dumb question, but how do you use an SD card?

 

You have to have the MM system it has a PCMCIA slot and you need an adaptor to take SDHC cards.
