2006 Audi nav plus sd card

[djt100]

Hi just bought an Audi a4 cab with a nav system in, behind the screen there are 2 sd card slots. Does anyone know what size sd cards these will take?

Thanks

4GB SD (SDHC/XC doesn't work)

Max number of readable files per card is 512 I think (from very distant memory!)

Excellent thanks
