Been using the Navionics maps in my Lowrance HDS 5 chart plotter. Like them much better than the Lowrance charts.
Well, broke the chip! I don't like leaving the chip in the machine, so remove it when leaving the boat. Well, I was pawing at it, the micro SD got half-way out of the carrier, and I pressed on it and cracked it. Went from chart data to junk in a dt! Navionics says 'Sorry, warranty doesn't cover physical damage'. Sure wish I could find a way to back up those things!
