It's really pretty easy.
First! Download your Settings file so if something goes wrong, you can recreate your system easily.
Second - I do these Firmware updates using External Power hooked up - I'd hate for the length of time the system is powered to run the battery down below some critical voltage and have the system crash and abort the update. The upgrade can take some time.
Third - Download the Firmware Update from the Dynon website and transfer to your thumbdrive.
Fourth - With Skyview powered up - insert the thumbdrive - press keys 7 and 8 to go to the Setup Menus. Toggle the left control knob to the right and select the top item - System Software. BTW - that top item is shaded out unless your have a thumbdrive installed.
Fifth - The first item after toggling right will be:
UPGRADE SYSTEM SOFTWARE
Select that item by toggling right.
It will then find the new Firmware version on your thumbdrive, or display a directory of the thumbdrive files (I can't remember - some selections require you to find the file and some find the file for you.) Better write down the File name in case you have to find it.
BTW - all SV files have to be in the thumbdrive Root Directory.
There will then be some "Are you Sure? safety questions - select - YES, and sit back while it updates. It may take quite a while. I think it may reboot the system at the end - I don't recall.
In any event, when you're done, you'll have the new Version installed and you can enjoy the new goodies.
This is also covered in the Dynon SV Installation Manual - Page 3-10 Rev"O". Also on the Dynon download page:

FYI - Version 7.0 is on the verge of release. It is due for release in September, and I have been checking every day. I want to be the first kid on the block with the new toy (I'm a techno-junkie), and need to be fed these goodies on a regular basis. The new version will add more great features - like Airport Diagrams. My mouth is watering.
Version 6.2 is the current Firmware. I don't know which version you are running - assume it's earlier than 6.0 - maybe 5.0? If so - you might want to download 6.2 and upgrade your system to get the hang of it. Then, when 7.0 gets released you'll be a Pro.
Don't let fear keep you in the past - the new features are really great - and easy to install.
BTW - I installed my USB drive port on the front panel above the Ignition module and I'm really glad I did so. I use my Thumbdrive on virtually every flight - either to Load Flight Plans, Download my last flight Data Files, Update the Nav and Terrain Databases (monthly), or update the Firmware - as we are discussing here. I don't know why Vans installed it on the bottom of the panel shelf.
Hope this helps,
