Ummm...of course. How did we not all think of this?

Thanks Ted.

I feel stupid now after overlooking something so obvious.

I can't wait to hear if this solves the problem for anyone else.

Also, what other problems might it solve?

Ted, care to share what clued you in to this?

Mine went super smooth. Did it while the car was running and driving it. Took about 25-30 minutes, had no maps or access to the infotainment system during the update. Last part is it has to reboot, and then takes a while (10 minutes or so) for everything to come back on as normal. Advise, don't turn the power off till its updating. Plus, be outside where it can get a signal.

NooYawkuh

That's how it went for me. I Started it when I left work the day it came out. At about 20-25 minutes, it was the longest OTA update I've received yet. Just finished as I pulled down my street. I would not dare turn the car off until it rebooted. With all these updates, whether map or infotainment, it's best not to get cute or clever with them. I do them all while the car is running and I don't shut it off until it's done.

RDX-Rick

A month has passed since this question was asked.

I have not received the notification yet. Have any other Canadians completed the update, or has anyone even received the notification on the screen?

EDIT: When I owned my 2016 RDX, there was a recall (around 2017-2018) to replace the communication module (TCU) because 3G was being shutdown here. Perhaps, because of that, all 3rd GEN models built in Canada already met the new standards and the upgrade is not required.

YES IT WORKS! Thank you so much as you saved me my second trip into the dealership. On the first visit they spent a couple hours trying to get the update to take, and then told me I had to come back and leave it there.

Bigwam111

thanks a bunch worked for me as well

Do you really think I could have thought of that myself! I actually just sent a chat to Acura online and then went through a couple of escalation and finally got to someone that understood the issue and they had a procedure to go through. I even ask the rep how they came up with this and they said "No clue! It was just something in one of our databases from one of the engineers"!

I was able to complete the OTA update to 1.6.2 back in November. Now that the February date is approaching is there any way to independently verify that the 3G to LTE firmware update is successfully completed or is the fact that the infotainment system shows that the current Acura Software Version on my car is indeed 1.6.2 sufficient for validating that the 3G to LTE firmware update was successful also?

Thanks!

arjaykay

According to JAGjr in another thread in this forum, after contacting Acura support, the 3G->4G update is totally separate from the 1.6.2 update and hasn't been pushed out yet to the vehicles that require it.

See TSB 21-029 - Product Improvement Campaign: 3G TCU VoLTE OTA Update in the 2019-2021 TSB threads for instructions on how to verify the various software versions installed.

ARNY

Thanks! Indeed it looks like there is a step in there to see what the TCU software version is. I'll check that on my car.

arjaykay

Just checked my RDX and it has the update. 2019 RDX Advanced. YAY!!! Thanks for the information on how to check for the update.

RJRDX

I just checked my RDX and it has the update. Thanks EE4Life for the information on how to check for the update.

I too am waiting for an over-the-air update. If we put the update on a USB key and update manually will it work? Is USB update country specific? Has anyone tried for Canada. I still have occasional Apple Car Play dropouts due to USB port not initializing due to me backing out of garage. Thx

russianDude

lol, i hate to disappoint you, new software does not fix usb initialization due to backing out

I contacted Camco Acura in Ottawa,ON last Friday and they have no idea when an OTA update to 1.6.2 is coming. The service advisor had no clue what I was talking about…had to go ask someone else. Typical Acura of Canada. Mickey Mouse operation.

westonc

I am in northern Canada. Started my car and saw the little red « ! » in the infotainment screen up beside the cell strength area so checked and it said update available. Started the update and it was successful.

Checked About and it shows Acura Software Version D1.2.1. Is this the correct place to look?

westonc

So per my post above it seems I went from D1.5.1 to D1.2.1. Odd

itsardx

Thank you!!! This worked for me, and save me all sorts of trouble. Mine was stuck at Step 6 as well. It is updating from Step 3 now.

I am in Canada and got the update today for my 2020 RDX.

itsardx

It is VIN/car specific, so if you get one for your car, it will work. I have done this in the past.

I am in Canada and got the update today for my 2020 RDX.[/QUOTE]

what version did yours change to?

I am in Canada with a 2020 as well and mine went from 1.5.1 to 1.2.1.

itsardx

1.6.2
I also verified the TCU update for 3G to LTE (from diag screen), it all looks good.

Your case is strange, as it seems like it rolled back the software. I would do a USB update to the latest.

I lost all my settings doing the update (probably because I got stuck), but I usually perform a factory reset after any update, so it didn’t bother me.

RDX-Rick

Another Canadian here.

It looks like the update for us has finally arrived. I went from 1.5.1 to 1.6.2 today with no problems.

FYI I was driving while the update took place. The progress bar had stopped when reaching the very top end in step 6 of 6, but after 15 minutes of it not progressing, I finally got he completion message.

itsardx

Yeph, USB issue is still there. I had issue with my USB stick with the 1.6.2, drove without waiting for Infotainment to boot, had to remove and plug the USB stick to fix the issue.

russianDude

so you were able to resolve it by simply plugging and unplugging? Mine goes dead and requires reboot

itsardx

Yes, in my case it says 'initializing' for ever, till I unplug the USB and plug it back, then it works.
For me, it happens, if, I do not wait for the infotainment to completely bootup before I start to drive (does not have to be reversing).

All these USB issues are probably due of the choice of USB 2.0 port, which will have a lot of compatibility issues with the USB sticks/Phones, we have these days (Most of them have to work in backward compatibility mode).
They will never be able to fix the USB issues completely.
But, I am glad that it somehow works 80% of the time for me.

PRM-RDX-3G

Thanks for the clarification RussianDude !

I'm struggling with the TCU software version validation. For the life of me I can't get step 5 on page 7 to work. Is the car supposed to be on or off when you do this? I've tried it both ways and pressing the back, home, and cards list buttons simultaneously isn't doing anything at all. What am I missing?

gtssenior

Step 5 on page 7 starts the verification that you are at the 4G/LTE level required for the TCU to keep working past Feb 22. Step 5 says to press the three top buttons Back, Home, and Cards List at the same time at the top of the touchpad. It does not say that you need to hold them down for a few seconds before releasing. Is that your problem?

Monster_HK

I received email for the urgent update for the Acura infotainment system. Is D.1.6.2 the latest software version? I don't see a icon on the update.

I think these were the exact same steps Marty McFly followed to get the Flux Capacitor to work again in the DeLorean.
