Updated my 2 to 3.4.4 with Vida
It was a little tricky but went well over all. Make sure you have a power source connected to the 12v battery.
My initial attempt was yesterday but the 12v drained to much before I could start the update, once you're too low vida won't let you start the update. Today the IHU updated failed but it automatically tried again and was successful.
Vida access and licenses ran about $85.
