As reported, I have the same (or at least very similar) issue with my Toyota C-HR resulting in the same error message. In the meantime I have tried to download the update, expand it and transfer it to another USB stick, inserted that. Now the nav unit is stuck in a loop, which tells me files are getting downloaded, "remaining time minutes" (without any number provided). I waited for three hours, but to no avail. Today I went to my Toyota dealer, who also had no idea how to solve the problem. Resetting the multimedia unit again didn't change anything, nor did disconnecting the 12-volt starter battery. I wouldn't be surprised if the only solution here would be to replace the unit - hopefully under warranty. After all, I got the update from an official Toyota website and not somewhere on the darknet. Apart from the fact that everyone was extremely polite and friendly as always, my 3.5-hour visit was not really successful. It hope it at least is another tiny step towards a solution. My contact promised to get in touch with the central technical department of Toyota in Germany to ask for a solution and get back to me as soon as possible. Keep your fingers crossed.

This is anything but reassuring news. 😱 I have a workshop appointment tomorrow. At least the problem has been fixed for you. 👍

I don't drive a Lexus, but basically have the same issues with the same map update, which I wanted to share with you: My Toyota C-HR (GR Sport, first registration 9/2022) uses the same multimedia unit "Toyota SMART CONNECT Plus (EU)" and the same map system. After buying our car in 2022, the map update menu showed an error and asked me to contact my dealer. The dealer installed the latest map update then, but could not solve the problem with the error message in the menu. As I live in Germany, I contacted the Toyota customer service center in Cologne and was told that an update would be released "very soon, probably in March 2023", provided as an OTA installation. This should resolve the error message. As I bought the Premium model, all map updates would also be carried out via the DCM digital communication module. Neither ever showed up. As the multimedia device was still displaying a software version of 2022/2023, I started googling and found the "Map Update for EU (MM21)" at https://www.toyota-tech.eu/. I downloaded the 21GB zip file and unzipped it onto a FAT32 formatted USB stick. I also entered my device ID and service code into the form to receive a licence key, which I then had to enter into the media unit to start the update. The licence key was accepted and I was then asked if I wanted to update the maps. No problems so far and also no hint, I might install a wrong software version. The upload took about 30 minutes and after driving for 25 minutes, I waited for the entire download to complete. The car was in READY-Mode the whole time. After the upload I got exactly the same error message with the same error code as shown in the first post in this thread. I tried restarting the multimedia unit by pressing the volume down button for several seconds and I also tried resetting the multimedia unit completely, but to no avail. I hesitate to do a hard reset by disconnecting the 12 volt battery but also believe, this wouldn't remove data from a non-volatile memory. The built-in navigation system has been unusable since then. My dealer has given me an appointment for 27 May to "re-upload the map material". Keep your fingers crossed.
