Understood. To be honest, I would probably be the same way, up to a point, and especially if I weren’t experiencing any major issues. After a career in IT I am somewhat “programmed” to obtain software updates as soon as available due to potential security ramifications. This predisposition makes it harder for me to wait, but I have been stung by a few software rollouts that weren’t fully baked so there are arguments on both sides of early adoption. To your point, I would also like to verify the OTA works as expected so I understand if there is a need to monitor the website for future releases.

Nope, very frustrated here too.....!

Per the bulletin, this one is intended to be installed primarily via WiFi, and in fact they recommend against the USB approach for some reason. In theory it rolls out via cellular and WiFi, but they suggest WiFi as the first choice.

Here's the recommendation against the USB:

NOTE
 The USB method should ONLY be used when the head unit is five or more versions out-of-date or if the Wi-Fi/Cellular method of updating is unsuccessful.
 Multiple files can NOT be on the same USB flash drive, if there are two files on the drive beginning with "rb_update" the software installation will not begin.

Here's the version table:

Table 1. Software Version Information
TYPE PREVIOUS VERSION CURRENT VERSION
HU Version 1002, 1005, 1007, 1020 1025
VD Version 1001 1010

Thanks for sharing those details. That strategy definitely represents a shift from older generation models. Now I see why owners are just waiting until a notice appears on the screen.

Got mine yesterday over cellular (OTA). The download took very little time and about 10 minutes to install. Restart and done. No issues.

Toyota/Lexus has really had a grab bag mix of approaches over the year, I've downloaded and installed many myself and had to practically beg dealers to install them in others (I usually just tell them to check at every service, and that I'm having Bluetooth and reboot issues, which is typically the case). I just wish they'd post the details somewhere customer could see them as I'm generally more interested than the typical service folks.

It is a little frustrating not to have gotten this one yet, the rollout has been going on for weeks now....I probably should just stop checking every day and it'll just show up.

Okay finally got the update.
however immediately afterwards my phone wouldn’t connect via Bluetooth. This was happening sporadically before. It connects after switching profiles/rebooting the console. So basically although they say they have addressed connectivity issues I don’t think they have fixed them all.

I’ll report on whether they have improved the “profile not loaded” issues.

I imagine they will continue to ship updates every six months as needed.

I would disconnect/remove your phone from car and add it back and try.

Always good especially after a software update be it for your phone or car to remove/add it back especially if you have issues

After reading this update I went to my 450h+ and was prompted to update. Despite checking the new iPhone app before and during the update saying no update available, the car report an update, downloaded and applied it! No issues to speak of post update.

Finally got the new software update this morning via OTA. So far don't see any changes.

Yep, this first one might be a smoke screen to buy some time until they can get the cats herded ( memory, profiles, smart keys, wallet keys, phone apps, etc. )

YMMV,

Sorry if this is a dumb question, new Lexus owner here. How do you check for update through the app?

NX450h

Oh I’m certain they fixed some bugs, probably not all of them and probably introduced some new ones. Such is the lifecycle of software. Will take time. I’m actually glad they aren’t making drastic changes (ahem Tesla) that disrupt things like muscle memory etc.

midcow3

@NX450h I agree small changes fixed. The problem with profiles/apps/smart keys/memory NOT FIXED - That is the current BIG issue, Lexus doesn't have a cat herder solution yet.

YMMV,

P.S. - Tesla is a software company and thinks and implements like a software company. Lexus is a customer oriented car company and not a software company; completely different update philosophy

nx450hfspt

Agree. Tesla's UI (both in-car and iOS app) is much more polished and smooth. I believe Toyota/Lexus outsources their software development or licenses from third party.
