Well I downloaded the software update on my SD card. Powered up my unit and rest to default sttings before I put the card in. Shut the unit down and put the card in. Powered the unit on and had a screen prompt to confirm I wanted to upgrade software. Confirmed to proceed. The update took about 3 min. and when it was completed I powered the unit off and removed the SD card.

Powered the unit back up and ran it in simulator mode. Very nice!! Gives extra screens with a 3D down view. Scrolling thru screens will allow the traditional views as well.

Thanks for the tip bassman! All said and done though, the side imaging is probably going to be the most usefull tool on this unit. The 480 foot view under the boat is the reason I bought this unit. Nice to have more options though.
