I want to download the Australia maps for my Navman S70 3D. I need to purchase an SD card to put it on ( I don't want to overwrite my UK/Europe maps already on the unit itself).
I was wondering what is the actual size of the SD card do I need to buy to fit on the Australia maps. I'm aware that the unit only takes a maximum of 2GB, but I have a 512MB SD card lying around and was wondering if this would be sufficient?
