A. Navionics is now "A Garmin Brand", as is so evidenced by those exact words said underneath the Navionics title on the Navionics website. Also, "Raymarine’s Axiom and Element-series displays are compatible with Navionics electronic charts." I wasn't suggesting that the OP go to the Garmin website and get the Garmin specific Navionics, more along the lines of getting whatever Navionics+ card that is compatible with his unit. But you knew that already...
Navionics offer detailed offshore and inland marine mapping content with rivers, perfect for planning your cruising and fishing adventure. Compatible with Raymarine Axiom and Element-series chartplotters.
