How to get Tesla's latest software update

November 12, 2019

Over-the-air software updates are great... but you never know when you’re going to get them. We’ve all been there waiting for the latest software update while others are already talking and sharing pictures about it on Twitter. Here's a few things you can do to make sure your car is ready for new Tesla updates.

Tesla 2019.36.2.1 Update

November 11, 2019

Version 2019.36.2.1 started being rolled out again on Friday Nov. 10th. [2019.36.1](/whats-in-tesla-software-update-2019-36-1/) had been stopped shortly after being released. Here you can read the main differences between the two versions and an updated chart with which models are getting what features.

What to do if Tesla update release notes are blank

November 10, 2019

It's been a while since, every time there's a new software update, I get blank release notes. I've seen quite a few people asking about this on social media, so I wanted to share how I do it to see the release notes after a software update.

What's in Tesla's software update 2019.36.1

November 5, 2019

During this past week, Tesla has started rolling out the software update 36.1. We’re not amongst the lucky ones who got it and it seems like now they’ve stopped distributing it. My guess is that they have found a bug and that we’ll see a .2 or .3 version being released in the next few days. 36.1 introduces some very attractive updates...

5 things to know before buying a Tesla

October 23, 2019

When I took delivery of my Model S, the very friendly and knowledgeable person who walked us through the ins and outs of the car told us 'Remember, a Tesla is still a car'. Every time I talk to someone new to Tesla I use that piece of advice. This post is about things that are fundamentally different in a Tesla car from any other car. Things about both the car and the experience of buying one.

2019.12 - Updated browser, software on demand, new games and more

2019.12 has been released to a few cars - surprisingly 2018.8.X is still releasing - and it brings a tesla browser, more Atari games, and the highly expected feature to download new software on demand. Honestly, reading the release notes we can’t tell if going forward we are going to be able to ask our car to download the newest software or if it would need Tesla to stage it as they do now. If is the later, I guess this is useful for folks not always on wifi or to know if something is wrong with your car and you should call your SC, but if is the former, we are really looking forward to it!

2019.16 is scheduled to be pushed on today (Thursday May 16th)

According to a support representative, 2019.16.1 should start releasing by the time you get this newsletter. Thanks to our great verygreen we know what is coming with 2019.16.1, and while it brings a lot of good stuff, it’s introducing some limitations for Tesla owners in Europe. According to the release notes:

  • Due to new local regulations, the limit of how far the steering wheel can turn while Autosteer is active has been adjusted. This may reduce Autosteer’s ability to complete sharp turns.
  • To initiate Auto Lane Change, the turn signal must be engaged to the first detent (held partially up or down) and the lane change must start within 5 seconds of engaging the turn signal.
  • Your phone must be actively connected to your car via Bluetooth while using Summon.

You can release the rest of the release notes here. Honestly, if I were in Europe I would wait to see what great things 2019.16.1 brings before updating.

2019.16 release notes

The release includes several goodies, I would recommend you to read the whole thing, but here are a few highlights:

  • Sentry mode has a new setting to keep it always on and exclude places
  • Set your software update preference and let Tesla know that you want them to send new software updates to your car as soon as they become available for your car and region
  • Conditional Speed Limits are now displayed - if they apply to your current road - under the regular speed limit sign. I assume this still doesn’t include cameras recognizing the speed limits but who knows

Do you need wi-fi for downloading new firmware?

There are a bunch of theories about what is necessary and what is not to download new software. Thanks to dennis_d and XXX - who have root access to their cars - we got some insights about how downloading new firmware works. Here are some of the details:

  • Tesla pushes a job ‘ firmware update’ to your car, the job says that it needs to wait for wifi to start the download process, the job usually says for how long it needs to wait for the wifi to start the download. After that date, the firmware can download over LTE.
  • If ‘Energy Saving Mode’ is enabled the car needs to be charging - maybe plugged does the trick? - or it would only download data 1 hour at the time, we assume to let the car sleep in between downloads.

Note: Map updates are different, they require wifi.

How to tell your car to check if there’s an update available

Some people say it’s a coincidence, but hundreds of people have reported this tip from Zack to actually work. If you want to help your car checking if there is a pending update, just tap a few times on the ‘Advanced’ button in the software menu. This only checks if the update is there, which in theory the car should be checking anyway. However, I’ve seen that not being really accurate, instead Tesla has to have approved your car configuration and region to get the update.

Is this the end of 'where is my software update' obsession?

Many of us feel FOMO every time that we get the notification that there is a new software version out. However, it seems like Elon wants to finally help us with it: «We will add a feature to allow request of latest software version».

When will we have it? Only Elon knows :P

New Software Update 2018.28.1

The release notes don’t include anything exciting but according to dennis_d - who is famous for seeing release notes that people can’t see - it includes the AP trial that Elon mentioned a couple of months ago, fixes traffic rendering on MCU1 as well, and seems to be unlocking the new navigation for all remaning MCU1 cars.

We assume Tesla is keeping the big guns for v9 we don’t expect the versions between now and the release of v9 to have many big improvements but even the small updates are welcome!

Software update process from the app in V9

Explained by beastpilot: «You get a normal notification, then in the app you can trigger it. Once you trigger it, you get ‘cancel update’ for 2 minutes, as well as a notification that a SW update is about to start. Once it starts the ‘cancel update’ goes away, and then you get a notification it finished once done.»

The new neural networks (really well) explained

Jimmy_d made an awesome job at explaining to us mortals how the new Neural Networks pushed on 2018.10.04 work. The three main types he observed are called main, fisheye and repeater. «I believe main is used for both the main and narrow forward facing cameras, that fisheye is used for the wide angle forward facing camera, and that repeater is used for both of the repeater cameras.»- he says.

What's in Tesla's software update 2019.36.1

Tesla started (and already stopped) releasing 2019.36.1. This release is one of the biggest in terms of excitement about the features being made available, but it’s also quite complex to understand who gets what since different motors, AP hardware, and other stuff play an important part in it. We created a comprehensive guide to summary what is in the release and what your Tesla will get, we hope you find it helpful!

What's new in beta 2018.21

Tesla release versions odd numbers have historically been betas only pushed to a handfull number of users (3 - 5 according to Teslafi) under an NDA. Last time that a beta was rolled out was a few weeks before the NN rewrote, so we have high hopes that this one includes something big as well. The lucky ones who have rooted their Tesla are dropping some bits of info on TMC, see below (Thanks BigD0g and dennis_d for all the info!):

  • Screen showing blind spot messages and detection (read more)
  • Improvement on how AP handles road dividers (read more)
  • AP2 running 2018.21 showing cars in adjacent lanes (ala AP1) (video)
