You probably don't have enough charge in the battery. Hook up a battery tender to the terminals under the hood and then try the update. If that doesn't work, you might want to have the battery under the passenger seat replaced.

 

This happened when I first attempted updates on our 2021. Cell service is terrible at my house, so I suspect software downloads were incomplete or corrupt. I had to have the dealer go in and erase the downloaded update then download and install a new one.

After that I put an extra Wifi router in the room over our garage. I went into the Defender settings menu, turned off cellular data and turned on Wifi and connected the Defender to my home Wifi. Every software update has downloaded and installed since.

 

so after the update my engine light went on and stayed on for a few days.

i was hours away from setting up what would prob be an expensive service appointment.

Light went off this morning, and the app shows no issues.

Thanks, Santa

 

loaded mine yesterday...nothing noticed

 

It’s typical LR irritation. Dropped ours at the dealer a couple weeks ago for an oil change and asked them to download/install. Invoice shows it was done. It popped up on the screen again last night.

 

Like you, my download worked and installing failed several times, but today, it worked. No problems so far, and i'm really interested to see if it's corrected the diff 'jump'.

 

My CarPlay always works so I've never updated anything on my '24. Has anyone gone in for an oil service and asked the advisor to NOT update software? This is what I want to try but I'm afraid a random tech is just going to update it anyway.

 

Last week I got a 2020 Defender 110 CPO. The software update screen says the vehicle's software is up to date. It says it had version 4.0.1 installed on September 6, 2023. I have the vehicle connected to my home wifi network and it says it's connected to AT&T with it's SIM. I am also signed in to my InControl account on this vehicle and can use the Remote app to control the vehicle.

Based on this thread, it looks like 4.2.1 is the latest version and there have been several other releases since 4.0.1 in Sept 2023.

Any way to force it to try to update? Is charging the main battery the only approach to try?

 

Updated to 4.2.1, carplay works.
Go figure.

 

Despite my warning not to install it, my wife did. Stuff works but navigation on carplay repeats spoken directions three times. Highly annoying. Using my phone and android auto ...it doesn't do that. Not sure if it's pivi related or not.
