New software update from Lowrance for the Mark and Elite series. Installed it tonight and it looks like it has a lot more fine tuning options for the charts. Hope it speeds up the Navionics map refresh, actually had to stop in mid-lake at Bridgeport today to let the map refresh, couple of humps just under the water out there that I wanted to keep an eye on.
