Hopefully this fixes some of your issues? This was posted on the Facebook group called "Lexus NX Group." I have no idea where the person got the picture and information from as I cannot find it online. Maybe it's something only Lexus owners can retrieve.

I just checked for the update in the head unit and it says there is no software update. I also went the route with the USB and it said my head unit was up-to-date.

A few things about this concern me. First of all if there was an update and my unit auto updated in the background with no notification, I am not too pleased with that. I like to know when my unit has been updated and there was no indication that this happened in the background.

also if it did automatically update in the background, this update did not fix any of the issues that I have been having.

software updates don't roll out all at once... it's generally done in phases once it hits production where they push out the update to some devices and then more and more etc as time passes... the reason is ensure sufficient bandwidth/server capacity and also to hedge against any issues that didnt' show up in testing, so that if an update causes an issue, they can pause it and figure it out/fix it and not have all devices affected

this is standard procedure

no different than cellphone updates, software updates for computers, websites ..updates are rolled out in phases and not everyone will get it at sametime

Haven’t notice anything yet on the NX.

My 2018 ES Navigation Head Unit takes updates automatically.

A bigger issue for me has been when Apple rolls out a new iOS version on my phone and causes issues with my car. I’ve had to work with Apple before and then mysteriously within days it’s all fine.

I worked in software for over 40 years. Making different software compatible with everything else can be a nightmare.

some companies do roll out their software updates at the same time and others don’t. Microsoft and Apple drop their updates all at once. It’s up to the company and whether they have the bandwdith to handle it or not. Companies like TiVo and Nvidia stagger their updates. I honestly don’t know how Lexus/Toyota stages their updates. At this point in time I don’t think Lexus has a big customer base with the NX 350 to worry about bandwidth concerns.

[/QUOTE Found this and did the steps. My NX has the latest software. https://www.lexus.com/firmware-updates/usb-steps

when I had my Toyota forerunner, there were a few times where I was prompted that there was a software update and it asked me if I wanted to apply it or not. I hope that Lexus gives us the option and doesn’t automatically force it.

I just checked my head unit thru the USB and the following link. Nothing is available for vehicle yet.

And Microsoft doesn't roll out update all at once either
eg windows 11 update

I'm guessing it requires you to accept it.... This is based on the maintenance guide "Check for available Over The Air updates and update upon customer authorization"

I seem to remember Toyota/Lexus forcing an update on folks once some years ago, so they probably have the capability to do so in case of "emergencies". Google has done the same thing on my phones over the years, most of the updates require me to accept them, but every once and a while they push one quietly.

I wonder if the update notice was posted prior to sending out the actual OTA to give dealers time to prepare for any calls. Also, I haven't found the website to be very dependable, I've gotten infotainment updates from the dealer that never showed up online for prior cars.

Don’t make the same mistake I did the last time I updated my RX. Make sure the USB flash drive is formatted as Fat32, otherwise the car won’t recognize it and will simply state “no updates available” or something to that effect. With past Lexus vehicles, you also could only use certain ports so make sure you aren’t plugging into a “power only” USB port.

i’ve never gotten them automatically on day one but I consistently get them proactively on day one.

when I said Microsoft rolls out updates all at once I was referring to what is commonly known as “patch Tuesday“, Not OS upgrades.

I worked in a large corporate data center and our whole business revolved around patch Tuesday.

Here's the detailed list of fixes in the patch, I've encountered several of them already:


The following conditions and performance improvements for Lexus Multimedia are addressed with this head unit software update:

• Abnormal Apple CarPlay® operation when multiple phones are connected via Bluetooth®.
• Unable to switch users when not in Park, the button is not grayed out.

Evidently they don't suggest using the USB method unless you're 5 or more versions out of date, not sure why.

Sounds like we'll need to use the local WiFi connection option to download this one, anyone want to give it a shot? You go to settings, Data/WiFi, then WiFi (not hotspot) and connect to your local WiFi network.

You then go to Software Update and it should work. My car out for the day, so I won't be able to give this a shot till tonight.
