Saw this uint demonstrated at a retail outlet and went on line to purchase. Price was competitive and shipping was very fast. Installation was easy since i was replacing and older Garmin fish finder with what i thought was a chart and fishfinder. today, i powered the unit up and took it out for a spin. To my surprise there was no chart data in the unit. Call Garmain and was told that i needed to order a SD chart card (another $160.00) for this uint for the area where i would be using it. To get a uint loaded with nautical charts you need to purchase the 500 series. So for all those pretty nautical pictures in the users manual and on the outside of the shipping box are just that. You certainly want see one of these on you 421S withour shelling out another $160.00
