I see I wired and installed my new C97 chartplotter. I placed the navionics silver Sd card that came with the unit into the slot and turned on the C97.I was told the silver card was UScoast including Chesapeake bay.I expected to see chart details like I had with my previous Garmin 740 including showing my boat in its slip etc in 2D. I repeated the process a couple of times. I am in the lower Chesapeake. No chart details.I expect to see details, depths, channel markers, etc.It shows no depths or channel markers, nothing at all , just the Chesapeake and land masses. Appreciate feed back.ThanksSee More
