Here is a compatibility chart I found for Navionics cards for the various GPS chartplotters FYI

It even has the Elite 5 DSI listed. The Navionics Plus card is kind of cool because its downloadable and allows you to pick your lake regardless of what state its in rather than have a region with lots of lakes you might not even be interested in.

Another useful like for your computer that allows you to look at lakes and rivers at home before you go out is Navionics Webapp Some may already be aware of these so Sorry if I am duplication info.
