Hi Steve,
As you are running 20190621, you
can update to the latest 20201101 version by .pgp from
https://pilotaware.lode.co.uk using a USB stick (for clarification you add the .pgp file to the memory stick, NOT directly to your microSD card). Anyone running anything older than 20190621, however, needs to do a full manual update.
As Alan has already said, you could also update by the App if you can persuade a friend or colleague with an up-to-date iPhone or iPad to help. Alternatively, if you have your PilotAware out of the plane, you can also connect it direct to your home (or airfield) router with an Ethernet cable and do a direct update via the router.
All these methods are described in detail in the in the Knowledge Base section of the PilotAware Website, (
https://pilotaware.com ) though for some mysterious reason ‘Update by Memory Stick’ isn’t listed in the Software Update Options, though it
is detailed in the full user manual for version 20200906 - obtainable on the same website (an updated manual hasn’t been released yet for 20201101, but the changes from 20200906 are relatively minor).
Hope this helps
Regards
Peter
