Hello. Spent 3 days searching the forums for this one. I have RNS-E in a 2004 allroad. I have a sandisk 512MB card which works fine. I also have a 2GB Sandisk Extreme 3 Card which won't work. Both have been formatted on the same PC, with the same tracks added to them. Both cards work in my camera. Extreme 3 is not an SD-HC, simply a normal SD card with faster write speeds. What might I be doing wrong please, or do I simply need to go and buy the cheaper, slower cards? Sorry if I have missed the answer somewhere!
