I have a small cruiser and on board is this Garmin
551s plotter. I use the cruiser in Poole harbour Dorset UK a lot and am a bit confused about updates. My questions are:
1. Poole harbour is known for its shifting sandbanks and the plotter shows the various deep-water channels. Does my plotter update the map showing the latest surveyed channels all by itself everytime I turn the unit on and there is a new update?
2. If not then can I get a free update via the web?
3. If not then can I buy a current
map showing the recently surveyed channels and download it to my PC. Assuming the answer is yes then can I use the SD card from my camera
to upload the plotter?
I have downloaded a copy of the “Garmin Express application” but cannot make any sense of it.
I wold be grateful for any advice. All I want to end up with is a map that has the latest information on Poole harbour channels dredged or otherwise.
