Map update error!

Vangelis82 · October 13

Hello everyone! Having the car two weeks now and loving it, but I made a mistake. I followed the instructions to the letter from the Lexus website to update the maps by myself. I began the procedure and at the very end it showed me that an error occurred and that I should contact my dealer. The onboard navigation is not working since and also the street sign alerts. I inserted the usb again and also restarting the car but nothing. Anyone any ideas?

The “Map Updates” topic has a lot of information about this issue. Basically you need to ensure that the USB drive is formatted to FAT32. Most people have resolved this issue by using the formatting app Rufus on a Windows computer.

I had exactly the same error, took it to the dealer and after four days of trying they failed to recover it, they ended up replacing the sat nav unit under warranty.

Unlike AWC, I just reformatted my USB drive to FAT32 using Rufus, put it back in the USB socket, and the update completed in less than 15 minutes. And I had the same error screen as you.

Hi Eddie,

Yours is not the same error code as the one Evangelos and I had, see my image:

So is it not safe to update map through USB pendrive? In the e-store inside MyLexus website i see there is an update available (my LBX show a "contact your dealer" in the update section of menu), but i'm not sure it's safe to update through USB.

Vangelis82 · October 14

I don’t think it’s safe. I tried a different usb but nothing… it’s shows the same message. I ‘m so disappointed because I didn’t deviate at all from the official instructions. Guess I should contact the dealer. But to reach to the extent of replacing the whole module of the screen has me seriously worried…

Aelod · October 14

What size USB are you using? Have you made sure it is correctly formatted to FAT32? Neither Windows nor Mac OS will correctly format to FAT32 if the USB is larger than 32GB. You need to use a 3rd party program to format larger USBs.

Vangelis82 · October 14

It’s a 64gb usb that I formatted it on a windows pc using rufus…

I also had this error and my nav is bricked for the moment. I used a 32gb usb 2.0 stick formatted for fat32. I have my NX booked into the dealer for next week. I hope it’s a quick fix. Agree this is very disappointing as I was told the car would get updates OTA then found I had to download them myself and then the update bricks the system. Stunning, Lexus!

I now have a major problem with my sat nav since the update. Getting the update itself was a big hassle as I posted in my thread.

However, my system totally crashes after about 10 miles into a journey. It goes into a cycle of updating itself and then all the map and voice direction disappear leaving the arrow icon on a blank page. A quick reset push on the button doesn't work while driving. I am emailing Lexus CR today but wondered if this happens to anyone else?

Suggestions to use Google maps etc don't appeal to me. Paying over £36k for a car that has such issues is annoying to say the very least!

Get the dealer to do it, they don't charge!

There wasn't a satnav unit in the country so I had to wait 6 weeks for one to be shipped in.

Given that your car is brand new, you should be able to use Android Auto or apple CarPlay. Given that Lexus navigation is usually rubbish and also out of date, why not use AA or ACP and use Waze (my personal favourite) or Google Maps, or Sygic, or TomTom, all of which are better than the factory offering?

Waze and Google Maps are updated (free of charge) on a daily basis and even 'on the fly' in the case of Waze. If you approach a traffic jam or roadworks for example, you can push a button and the info will be uploaded and pushed out to all Wazers within minutes.

Having experienced OTA Lexus Up-dates in 2018 that reduced the Alert volume for speed cameras I could not wait for ACP.

ACP in the LBX is instant/rap[id If you have an Iphone.

I did the map update and got the message that all was good from the car 🙂

Untill I drove the car with the updated navigation system. Since the update the systems starts after a short drive restarting the navigation and after a couple of re-starts it even resets the complete multi media system during driving. Unfortunate it doesn't connect with my profile but just connects as a guest.

Luckily is driving not affected but navigation doesn't work properly (and your settings are of course not loaded). 😞

I will contact the dealer later this week, this is very strange..... More people with this problem ?

Had the same issue after a succesfull map update. I did a soft reset which solved the problem (press and hold the volume button)

@rpad, thanks for your reaction. Did this help to prevent re-occuring of the issue ?

thanks.

They didn't reply to my question (email) anymore (really poor aftersale service). I'll try asking Lexus directly as the dealer is quite far from me (80km).

A short update.
For me, it happened again. It got worse, after a couple of minutes driving with the navigation the system get's into problems.
Driving with Android Auto navigation looks to be functioning flawless. But I hate if systems do not perform as they should and like the directions in the HUD during navigation.

Therefore I tried the factory reset option. All settings are lost (except the milage) and the connection to the app has to be re-initiated.
This looks to be solving the problems. The navigation was functioning fine during a short test drive (about 20 minutes drive) 🙂

I keep my fingers crossed and hope this will be the solution for my problem. Otherwise I have to go to the dealer.

Vangelis82 · October 26

Just to keep you updated… I contacted the dealer and send them the error codes. They didn’t have a clue… I drove there and they did everything I’ve already tried such as resetting the settings. I left without a solution and yesterday the informed me the they forwarded the issue to Toyota Motor Europe for further investigation. So we wait…

Unfortunate is the problem back.🙁
I did yesterday a longer drive (longer then one hour drive) and the navigation system started to recalculate, dropped the screen, recalculated after 2 minutes, black screen, reset of multimedia system with Lexus logo and shows the map without the programmed route (and in guest mode so kept no record of the drive in the app).

The Multimedia system looks to be stable while not using the navigation actively. Also using Android Auto (Google Maps) works good. So the problem is with the calculated route in the Lexus navigation.....

guinchy · October 26

Exactly the same for me last night just as the entrance to the A1M was closed and the diversion signs were useless, the system did the same and the screen ended up showing as attached.

I had reported this to Lexus (no confidence in the dealership from previous issues with this) but they back heeled it to the dealership who called me on Monday. After detailed explanation, he said he would contact Lexus Multimedia. Heard nothing back yet but both will be hearing from me on Monday.

I had the same error code as Vangelis82. Trying to resume the update with a different memory stick didn’t help. The dealer responded quickly to say that a “module” needed replacement. There’s a month’s wait for the part.

The good news is that while the satnav is down I don’t get any speed limit warnings! The car is much nicer to drive because I’m focused on the road (including speed limits) instead of looking at the HUD continuously to try to keep my speed 1mph under the limit. apple CarPlay navigation still works, including directions on the HUD. If it weren’t for the permanent error message on the dials display, I’d be tempted to leave it unfixed :-).
