Hi Dale,
Good to meet you at the meeting, chatted keepering briefly. I have had Navionics on my phone and Ipad for a few years and it is a real game changer. I have just last week managed to download Navionics onto my Simrad plotter on the boat, but it has taken me a long time, however i am a techy dinasoar!!!! All the above posts are great advice, hopefully see you out on the water when the weather decides to sort itself out.
