Now Cane I know you have a bunch of these smaller memory card stuffed in a drawer somewhere in your house. Also check your camera boxes as they sometimes come with a small memory card to help get people started. I use GPS track maker but any converter will work.

Make sure to down load the latest operating software also from Lowrance.

I have card reader also. If you want to borrow it just send your SI unit to me and I will hold it for you until you return it.:D

Or.... If you can find a smaller SD card w/ your waypoints you can mail it to me with a return envelope and I could send it back with the converted waypoints and the updated version software. Your trying to go HB to Lowrance format right?
Frogger is right. A 256 is plenty big enough.
