I have read info for a SD card but my Tomtom has a sticker over the sd connection saying no SD required. I wonder if I do need one as my tomtom did not have any POI's in it when I purchased it and the ones I do have I got from a web site that tomtom tech support gave me. With the download from the web site I do have some restuarants but not many and I not sure some are even in the area I live in.
