I have been trying to get the system to download updates via a external wifi connection, but after a few minutes with the engine turned off the Sensus system stop and turns itself off, presumably to prevent draining the battery.
I found a web page about downloading apps (https://www.volvocars.com/uk/support/ar ... 51726d91dd) that says
I've tried connecting a battery charger but it appears to make no difference, anybody worked out how to keep the system active while downloading and applying updates - without keeping the engine running?Updating tips: An update takes about 15 minutes and the infotainment system must be on. Use a battery charger or keep the car's engine running while the update is in progress, for example during a journey.
