Can I ask any owners with gen 1 NX or gen 4 RX or any vehicle with MM19 infotainment if they have been forced on to the new app, whether anything still works? The original app has at least some functionality but the new version essentially has none. Trip data does not even update. Is this a problem specific to me, or is everyone (not on MM21) seeing the same? Paul

Ahhh.... Sorry for the misunderstanding. Removal of the hotspot subscription capability unfortunately does not make it free (that would be nice). It has simply stopped the hotspot working altogether!! At least it has in my case....

I know a lot has been written on here about not being able to rewrite the CAN software but I understand this is exactly what JLR has done? I think I read that they detect the intentional bus errors caused by the CAN injector within some time window and apply a timeout... At least I have not just taken delivery of brand new, and still CANbus vulnerable, LC500 ultimate edition.... You guys must be even more furious than us RX4 owners.... Paul

So no actual fix on the CANbus? After all this time? It can't be? Paul

I believe mobile phone hotspots are not very well compatible with MM19 systems anymore with up to date versions of android. I mean, it should connect the first time, but the car will not reconnect without you typing in your password each time so it cannot be automated as you require. The internal hotspot will work without retyping the passwords but Lexus Link "plus" (which I think we are now all forced on to) removes the hotspot subscription capability. Paul

absolutely agree

So this will not stop them opening the doors with the CAN injection?

MultiMedia system release, with the number nominally being the year of release. For example the new NX and RX have MM21. Paul

Totally agreed, Ronnie.

MM13 and MM15 have the post code entry on page 2. MM17/19 have postcode as part of the address section (which must be what you have, Paul). I think OP's 2018 RX will have MM15? Paul

I was rather hoping it would be a fix to the CAN injection issue directly, and hence stop thieves opening the doors. An immobilizer will not stop them unlocking the car using CAN injection, will it?

Interesting. I have a very old version of the MM19 audio software release on my MY21 RX because the newer releases exhibit exactly the same issue you have described with MM21. I spent ages trying to help Lexus debug it but in the end they never fixed it. I remain astonished at the lack of regression testing performed on their software releases.

They may be able to do what the call a "glue pull" where they do not need to get behind it.

Yes, I hope so, Al. It's just that this morning the lift gate worked ok at the dealer! (typical!) Thanks, Paul

Hi All, The power lift gate has been sticking on our 2015 NX and was unable to close by itself yesterday. I'm not familiar with the level of granularity of OBD codes that may be generated in such a circumstance. Does anyone know if a broken or sticking motorized strut would generate an OBD code? Many thanks, Paul

It's odd that it worked on an IS but not a facelift NX. Does any other stick get recognised in the car? You have two sockets in that gen of NX I think in the centre console, both of which should support data. Have you tried both sockets? How large is the stick? I believe an MM17 or MM19 (if you have car play or android auto) should support 128GB minimum, but must be formatted FAT32. I'm hesitant to say, because it's easy to blame the car, but as the same stick worked in an IS300h (with probably MM13?) perhaps the USB ports in the NX are broken because MM17/19 should be able to read anything that MM13 can read. Please check these things and let us know. Paul

I remember reading something else on here that there was indeed some conflict between android auto and the some notifications. So I guess that is the problem, not the wiring. Paul

Katrina, I think you need to go into general settings and turn off "auto change to screen". Slightly cryptic labelling of the function but I think that is the one that causes it to go back to map view after 20s or so. Paul

Did they say which year?!! 🙂 Paul

In my case map updates are still free (that may be the last one that is though) so no point in not updating it. It also integrates with the HUD (which on my vehicle AA and ACP do not). You are correct that on MM19 systems the map data is 6 months old when released. Paul

I was at the dealer yesterday and the new fix mentioned by Lexus in March is not yet available. (All that there is currently is the RX CANbus plate) Paul

You should be able to download the updates from Lexus Tech and do it yourself. https://www.lexus-tech.eu/ Just beware that if it goes wrong, it may cost you a new multimedia unit.... (if it goes wrong with the dealer doing it then it would be up to them to put it right) Paul

Just to let everyone know - for MM17 and MM19 systems - 2024v1 maps have been released (based on Q3 2023 map data) and when loaded via USB stick they work fine (as do speed camera alerts - which may not work if on OTA update is done). It took the usual 65 to 70 minutes to complete. Paul

Interesting that all the user comments and Lexus replies from that Lexus magazine web page have gone missing!

Unfortunately this looks like scratches rather than the coating lifting off. Not sure if you can get a new plastic cover? (Issue is it may only be sold with the screen as one part). Paul
