I drive a 2007 S350, European model. I am planning on getting a Compact flash card in order to use with the PCM slot, as the local dealer still does not offer ipod integration kit. Anyway, I was just wondering what is the maximum MP3s you can put on the CF card, so the S class could read them all and play? Because I saw a couple of times on the internet, people saying it is up to 1500 songs? I just want to know so that I can decide what size card to buy, as if there is the restriction, I won't be needing the 16 or 32 gb cards.
