Yes, well sort of via Garmin on line. I have the 555s version. The numbers for Europe
and the US are always slightly different but underneath its the same basic Ford.
The problem I had was the Vision 2 card (499mb) that I bought separately from the Garmin was too small for the updated chart (526mb) bought on line from Garmin. So I needed to buy a new 2Gb SD card (anyone one will do), but the 555 operating software
had to be updated first to recognise 2Gc cards, using the new SD card. Then format the SD card and stick it in to download a XML file so the on line system knows you have a Garmin and are not counter fitting etc. Then you can download the updated chart and finally install it in the Garmin. Needless to say the manual doesn't tell you to do this or the web site and it took weeks of back and forth to the boat to finally get it sorted with Garmin's tech help.
So this is what the SD card should look like once the XML file from the Garmin unit and the downloaded files from on line with the new Vision chart.
The small Garmins will show tracks and if connected to AIS
your future course and that of the courses of any other AIS
targets which are on a collision
course as well as firing off the alarm
showing impending your impending doom if you don't do something.
