The new FICM MCU doesn't fix BT issues...
Not for me at lease !

I finally got R67. No more BT issues. Glad they finally fixed it.

Yep, agree. I got my R67 upgrade first week of Sept and have had zero issues since.

Have you still got the slider to adjust battery charge limit now R67 is in?

I do

I can confirm, that SE R40 is pretty good on bluetooth as well! Hopefully it stays that way.

Yep because MCU was 68.4.7.0 but upgrade to 68.4.9.0 anyway.
R63/R67 required at least 68.4.7.0

You can use ABRP without a dongle. If you have homeassistant (or any other linux based server) you can install saic-mqtt-bridge and feed your car data directly to ABRP via it's developer id. Much more reliable and convinient than a dongle.

And to top it all off, you can map ABRP to one of the steering buttons and you have a seamless experience (for the most part).

And honestly, apart from tesla, ABRP is pretty much the best and most accurate routing app. If you give it the right data and train it enough, it becomes really accurate. Certanly much better than what most OEMs build into their cars.

Hey mate. I live in Türkiye but I am using EU version of i-smart. When I launch the saic-mqtt-bridge on my home server it says registiration is not found but I double checked credidentals all is good. Also app is working I can connect the car. What might be the issue?

looks like maybe the dealer didn't complete the update process using SIPS.

Reckon so, it is booked to go back in.

Hello everyone. I just tried updating from R46 to R67 on my 2022 Luxury using the file from the OneDrive link a few pages back. After the AVN MPU update, the system booted up as expected. However, the Infotainment System ECU update failed, and now it tries to run the update again every time I start the car. I also noticed that the slider for setting the charging limit is not functional. I then tried to revert back to R46, but that doesn’t work at all — the entire infotainment screen turns grey, and on the second page, I can only access the settings menu. Does anyone know this issue and how I can either complete the ECU update or revert back to R46 if necessary?

Maybe unplug the battery for 10 minutes.
That solved a similar problem for me.

after the R67 Update?

I’ve never come across the update failure issue…

Could you post a few photos?

With R67, the MCU should be updated to version 68.4.7.0 or later. That explains the problem with the slider, though it does not account for the other bugs you’re experiencing.

Yes, you’re right the MCU software version on my system is lower, as you can see in the picture. How can I update it, or is that something I can even do myself? In one of the photos, you can see the message in German saying “Update failed. Please reinstall.” And as shown in the other photos, the slider doesn’t work properly. I don’t have any photos from after the downgrade to R46, when the entire infotainment system stopped working, and I won’t have time today to reproduce it. But maybe you can help me get R67 running properly.
