I can, no problem, I'll even do it for you...you will need to bring a laptop with Basecamp loaded.
yes you can or could use basecamp without a garmin i found a way a few years back and it should still work. Download osm maps then you will have a fully detailed map to use in base camp. osm maps seem popular with certain groups and do appear to be quite detailed.. as with all these things there was a draw back once i started loading maps of more than one country etc you could only have one at once open least i only got that far. in the end i just plugged a garmin in but your stuck with the maps in that garmin but most can be upgraded. osm maps worked without the need for an internet connection and ran as replacement for a garmin unit.
not tried this for a while now
