Meant to insert Self updateable
You will buy a simple mod Say VV/VW 10 watts 6 volts.
You want 20 watts the upgrade software will cost X$
Temp= X$
100, 200 watts = X$
You will end up ordering the Items you want at a cost for each. Just like computer programs. You will have to have a key to make them work and you will pay for that.
Just my 2cents
