Installing Software Update
Hoping that I might tap into the collective wisdom/knowledge for some help with installing the latest software update on my 2020 Defender 110 D240. I bought the car 2nd hand in May 25 - the last update was installed in Dec 24. Each time I turn off the car, it tells me that the latest update has been downloaded and needs to be installed. I have tried repeatedly to install it by selecting "Update now", ensuring that there is a good connection to my home wifi and double locking the vehicle - but with no luck. I have tried charging the battery fully and that didn't work - I have tried to install it with the battery charger connected - no luck either.

I understand that it needs a good battery to install. The "Stop Start" doesn't work - is that an indication of a weak battery and might that be the issue stopping the install? I suspect that the car still has the original battery but before I replace the battery, does anyone know of anything else that I can try to make the install work? 2020 LR Defender 110 D240

Thank you and if you mean activating the alarm by locking the vehicle and then pressing the lock button again within 3 secs - then yes - I think so! 2020 LR Defender 110 D240

I think double pressing the button on the key fob should be enough.

Don't forget the BCM needs resetting when the new battery is fitted.
