Default Question about GPS / Chartplotter maps
I have a Humminbird 786ci Chartplotter. It comes with Humminbird Unimaps installed on it but you can upgrade to the Navionic HotMaps Premium by purchasing a SD card. Has anyone ever bought these upgraded maps? Are they much better than the stock Unimap?
