As you already have the November update installed, you would be much quicker updating via USB stick. Go to PilotAware.lode.co.uk from a laptop or PC and download the update file. Copy it to the root (top level) of your USB stick and make sure it is still named 'pilotaware.pgp' (without the inverted commas). Power up our PAW THEN plug in the memory stick. Leave it a few minutes and when you check for updates you will see the new file. Simply click install and within a few minutes it will have loaded, then unplug the memory stick. If using the same stick for the next update, don't forget to delete the 'old' file first or Windows will rename the new one and PilotAware won't recognise it.
