Looking for new GPS Combo Down Imaging

The one I just ordered has gps, so I would assume it has speed. I sent a question to Cabela's which is on the listing on the 597 ci HD DI, etc. along with other questions. I know I asked about water temp, but I can't remember if I asked about speed. The answer to whatever I asked was yes.

yes speed and water and temp. but if you need the ethernet you will have to go to the 788 and up series

If I had an ethernet, I would have to get my wife or kids to do it.
