Hi,
sorry for the noobie question, but I don't seem to be able to find the answer:

I would like to install "Garmin BlueChart G2 Vision VEU704L France" unto a Nuvi 550.

I saw that the map is available to download from maps/105110-garmin-bluechart-g2-vision-veu704l-france.html, but how can I install it once i have downloaded it?

Many thanks in advance
