Don't think that's possible with the Garmin stuff, but if you are

In the current version of the software, it only uses ARCS british admiralty

Color me naive but 400 bloody pounds for the SW then more for the charts
seems a bit expensive when one can buy equivalent land navigation SW for
$39(US) that includes maps.
