MM17/19 Nav map update 2020v2 released


Recommended Posts

According to the tech website, the next version of the navigation maps for newer navigation systems has been released. 
2020v2 is now available. 
 

I may try doing the update directly in the car rather than downloading onto USB. A job for the weekend...

I had some time this evening so I've done it already...

Pretty straightforward but took much longer than I expected.

Once I asked the car system to check for updates I was presented with this screen.  The download size is quite small (must only contain changes rather than the whole map) and it is for GB and Ireland only:

The download then started with the % completed showing... It took about 15 minutes to download - my WiFi signal is quite weak outside so it was slower than expected:

Once downloaded the installation started.  I expected this to be quite quick for such a small download.  However it took around 40 minutes!

Once complete the 'Current map version' screen reported the following:

Note: the main software update screen still reports the Nav software to be 2020v1

 

No codes / payment / activation needed.  My infotainment system already has my lexus.co.uk login details programmed in.

 

Hope that information is useful.

Thanks Phil - really helpful.

I'm not sure if I will go to the bother of doing it as I rarely exit out of Android Auto into the Lexus system now.

Thanks for the update.  Just doing my RX now OTA.  4 minutes to download followed by 30 minutes to install.  
I should add that the update was done using the car’s WiFi router.  It had a better strength than that on my phone even though I was parked on the drive just a few feet from the house router.

I noticed, after updating the RX nav software, that my firmware page has a greyed out ‘Update software’ button on the bottom right of the screen.  Is it like this on the NX?  I know my firmware is probably out of date and it would have been useful to do the update OTA like the maps.

It’s the same on my NX. The update software button only lights up when a USB stick with new software is detected. The firmware can’t be updated over the air.

Thanks.  Back to Lexus Tech then.

Folks help requested

 

Just tried to download the latest upgrade maps. Do these file sizes look good?

I am aware we are only download updates this time for GB and Ireland so the file will be smaller.  

Also I tried to do an OTA upgrade but that option is greyed out in the car even though I have an excellent WiFi signal - I'm what am I missing?

 

Thanks

 

Dennis

The files you have downloaded will be the full Europe update - no issue using them via USB in the car. I actually did the full update over the weekend rather than keep just the UK update I’d previously installed. 
 

Is your car system logged into Lexus Online (have you entered a username/password in the past)?  That’s the only reason I can think of for the option to be greyed out.

Another thought - if you mean the ‘Update Software’ button in the ‘Software Update’ screen, this isn’t the correct button for OTA updates. This is the USB firmware updates only. 
 

You need to access the ‘Online’ section from the menu down the left hand side. I think it is underneath WiFi.
