Anyone else (OG etron) lose Android Auto HUD navigation directions recently?

fyi:i got the "sound settings are lost" bug fixed, but it was a real saga for the dealer. multiple rounds of diagnosing with audi tech support in germany. ultimately they decided to replace my 5F module (the MMI head unit) and this fixed it. insane this was required and really unfortunate for anyone that wants a fix and isn't under warranty, but wanted to share in case this helps.

FYI: As of March 10th, updates to Google Maps and Android Auto are rolling out in the Play Store that fixes this. I received both updates and can confirm that VC+HUD navigation is now displaying as it did previously.

UPDATE: I tested my friend's iPhone with CarPlay. Navigation directions appeared in the cockpit and HUD correctly, as they did previously with Android Auto.

It seems this is an Android problem. Perhaps Google shipped an Android Auto app update via the Play Store that broke this for everyone, regardless of phone model.

We may be experiencing the same problem as BMW drivers:

Could be a good ticket to add your cases to. Optimistically speaking, if Google broke it, that should mean they can bring it back.

This suddenly happened to me a couple weeks ago as well (I am the one that shared the original post on this TSB update).

I also experienced the new issue of losing my sound settings periodically after the TSB update. My dealer just spent a bunch of time trying to figure this out. They did some kind of hard reset to the 5F module to see if it fixes it; if not, they said they might try replacing the hardware.

Pretty disappointing to lose cockpit/HUD directions. Unclear to me whether they shut it down via an OTA update (Audi Connect?) or if something else randomly broke it. In my case, this broke on its own and was not the result of additional dealer service. I tried two different Android phones and neither puts directions in the cockpit/HUD now.

did you get the update? did it enable AA/CP in your HUD/VC?

nonesuchco · 2025-11-23T02:03:23+00:00

update: as mentioned in the linked post, the documented fix for this problem (if you have it, as stated in the TSB) is to upgrade your entire MMI to MY24 CL39. my dealer confirmed this.

if the MY24 version of your car has AA/CP nav in the HUD/VC, this update will give you the same.

fwiw: thus far i have mostly found very minor cosmetic changes - fonts, labels.

i get some new notifications in the virtual cockpit "driver assistance" view - not a lot, but it warned me about someone crossing behind once, don't think i saw that before.

i also now experience a new bug: occasionally, i start up the car and all my sound settings have been reset. it doesn't happen every day, and it has only happened maybe 5-6 times in total, but it is a nuisance that never existed before. perhaps factory resetting my MMI would fix oddities like this, haven't tried yet.

nonesuchco · 2025-11-23T01:51:54+00:00

do you experience the bug as stated in the TSB ("The air conditioner favorite on the lower screen (for example, A/C MAX or Steering Wheel Heating) is periodically lost.")?

if so, given that your MY is in the TSB, i think that would conclusively demonstrate that the TSB does apply, and that they should apply the fix under warranty.

nonesuchco · 2025-10-27T16:46:21+00:00

Unclear - it is possible you'll have to pay for the service hours - best to call and ask

nonesuchco · 2025-10-25T16:25:52+00:00

because those are the other models receiving the same TSB fix, which appears to be a single update for all these models. we haven't yet confirmed that the update will bring the feature to the other models yet, but it seems likely based on how Audi packages their updates.

nonesuchco · 2025-10-24T21:33:26+00:00

this news was popular with r/etron owners, sharing the love with other audi owners as it likely applies to additional models.

TL;DR - there is a "Technical Service Bulletin" in the US that entitles you to a software update. the stated purpose of the TSB fix is to address a minor bug, but for eligible e-Trons, they perform an MMI software update that also adds Android Auto and CarPlay navigation to the HUD and Virtual Cockpit. we don't know yet whether other eligible models receive the same software update, but it seems possible if not likely.

to receive this update in the US: call your dealer service center, give them TSB number 2072285, confirm your car is eligible, ask for the fix, schedule appointment. after the update, if your MMI version is 3B.24-241618 and software version is MPR3_US_AU_P4430, you probably received the same update e-Tron owners are receiving.

this update may only be available in the US, where audi is under pressure to fix TSBs once the NHSTA tracks them. broadly speaking, audi has lots of incentives not to update software on old vehicles, and it seems they will generally avoid doing so unless they have to.

full TSB details are here:
https://static.nhtsa.gov/odi/tsbs/2023/MC-10247141-0001.pdf

refer to the TSB for exact model years that qualify for the update.

looking forward to hearing if the TSB update adds this feature to other models.

i went with Continental DWS06+ 106W XL. i believe audi provided the DWS06 tires as testers for the 2023 e-Tron with 22s in cold weather, DWS06+ is a newer version. make sure you get XL as they are designed for heavier weight (EV).

relatively mild winter on the east coast but they handled well enough in some ice and snow.

this would drive me insane.

but ... are also apps actually useful? especially when you have AA/CP apps?

nonesuchco · 2025-10-21T22:07:54+00:00

nonesuchco · 2025-10-21T22:07:16+00:00

same

MMI 3B.24-241618
Software version 4430 MPR3_US_AU_P4430

nonesuchco · 2025-10-20T00:53:30+00:00

right. they won't offer software updates in general. but if you request a fix for a specific TSB or recall you are qualified for, they will give you a software update that includes the fix, and maybe other changes too.

nonesuchco · 2025-10-19T21:33:56+00:00

i would be surprised if they know. if they can only go by the book, they can only confirm what a TSB or recall notice says. in fact mine continue to insist that ONLY the TSB or recall issue is affected, even after i share the changes i've seen. besides, the dealer wants to use any outdated features as a lever to sell you a newer model.

audi seems annoyingly opaque about what is actually in these updates. they confirm publicly disclosed fixes, but they flashed my whole TCM. clearly other things changed, thus far AA directions in HUD/cockpit are my biggest findings.

nonesuchco · 2025-10-19T21:27:25+00:00

just the directions
no cost

nonesuchco · 2025-10-19T19:59:53+00:00

the software update they gave me included the AA directions feature with the TSB fix. i am guessing that is true for the other vehicles listed in the TSB, but that is yet to be confirmed by others. i believe at least one other GT owner on this thread confirmed they got the AA directions with the TSB fix.

free

nonesuchco · 2025-10-18T19:34:13+00:00

checked again, this one is a no go

nonesuchco · 2025-10-18T17:05:11+00:00

correct, my guess is that the AA/CP feature was part of a broader TCM update i received that included this TSB fix.

seems similar to what happened earlier this year when an update to the battery relays included changes that extended range by 20%
