I had mine in the dealership getting the window fixed and an update done a couple months ago. I think you needed a certain update to be able to do them in the future over your Wi-Fi. Does anyone have a pdf or guide on how to setup the Disco to use house Wi-Fi to do updates? I just installed a mesh Wi-Fi system so I have access out in my garage and want to let it do it’s thing.

on a complete other note... where is the second battery for this vehicle and how often does it need to be replaced? She’s starting to sometimes crank too long and I think I might need a new battery.

 

There is only one battery. Behind the right hand side panel in the boot / trunk area
What's the voltage level when engine is off?

 

Set it up to connect to your wifi network under settings and connectivity

Once on the wifi you can go to settings and I believe updates. The latest I was able to install was 19C, had to be on 19A or 18D for SOTA to work.

 

...or if you have active 4G service you pay for, it will update over cellular.
