Tesla infotainment system upgradeable from MCU1 to MCU2

[chillaban]

that's an interesting problem (the software update) I hadn't thought of. Couldn't you go do it at Starbucks or McDonalds on their wifi instead? Or while you're parked anywhere where the car has internet for longer than 40 minutes? Seems to be how long those updates take me.

Captive portals do not work with a Tesla. The car immediately tries to fetch a few websites via shell script and if that doesn’t work it disconnects.

I can leave my tethering phone in my car, which is what I do sometime, but this is a high break in area so I don’t like leaving my car alone with a phone in it.

We have a Model S MCU1 and a Model 3. The Model 3 can finish downloading over 5GHz Wi-Fi in about 5 minutes. 10 at the most. The Model S takes almost a half hour to do the download and then another half hour to 45 minutes to verify the update before the alarm clock shows up.


So yeah one of us can easily get updates by tethering on the way to work. The other one circles around a parking lot if it looks like it’s still downloading because shifting into reverse disconnects the Wi-Fi.

I don't disagree with what you're saying. Just wondering what the chances were that they would let you upgrade for the difference between the two.

Verygreen s said there is a bulletin in tesla service to replace ap2.5 cars with mcu2

Anyone got a source/reason for this? I don't want to pay for this upgrade if it's free .

That's great if you have AP2.5. I have AP2

 

[⚡️ELECTROMAN⚡️]

AP2.0 is the red headed stepchild of Tesla.

Oh, I thought that was AP1

I think here is where people are hearing of this. green on Twitter

AP1 was left on in the wicker basket on the steps of a nearby orphanage.

Ouch! Lol.

I'd say AP2+ is the latest generation iPhone with Face ID, multiple cameras, OLED, etc., Whereas AP1 is a good old iPhone 5. It can't do any of the cool new stuff, but what it can do (make phone calls, send text messages, check emails) it does well. It just works.

Mine will update on LTE. Did it last week while shopping. 40 mins.

I’ve never received an update over LTE except when pushed. It’s always the day after a major update push I will tether and it suddenly starts downloading hundreds of megabytes.

Certain critical updates get pushed over LTE. The 2018.8.x updates close some rooting holes.

Other than that, they’ve been pretty stingy with LTE and don’t set the “download over LTE” date to anything in the next decade.

Your MCU (not just the screen) would have to fail first though...

Yes, or if you just missed the switch from mcu1 to mcu2 you could could wait it out until they run out of tegras. I mean how long can nvidia supply them with a chip that's 10 years old

Was just updated to 2019.12.1.1 and was told that this would solve the crashing McU1 issues, stuttering audio, etc.

Well, guess what? It didn’t do squat to fix any of it. Nada. Zip. Zilch. Zero.

This is why I’m upset about having an MCU1 car that missed the cutoff by a day. I now have a car that’s just over a year old and is randomly crashing while driving, the audio sounds like garbage when driving, homelink will occasionally stop working, text display issues, and on and on and on.

Get the retrofits going all ready. V9 continues to be a freaking bad dream.

There are thousands like you in the same boat with all the MCU/1 issues.

Here hoping the retrofit comes out by end of year. Anything below $3000 will be good for me.

I think MCU2 has most/all of those issues too. They’re just faster.

 

[⚡️ELECTROMAN⚡️]

Sounds like a Version 9 issue. My MCU is working fine on Version 8. I can't believe they haven't fixed Version 9 for S and X yet. We shouldn't have to spend money on a new MCU for our UI to work properly. That's ridiculous.

 

[Cheburashka]

The UI is way smoother now on MCU1 with 12.1.1

 

[KyleDay]

I also have mcu1 but honestly don't have freezing or skipping issues at all. My MCU is slow, obviously, and the web browser simply doesn't work, but everything else is usable.

I wonder why others have a hard time and mine is fine. I use it daily and am not ignorant- I use it to its fullest all the time. It's just solid usually.

 

[commasign]

Yeah, same here. MCU1 on my S and X work fine. MCU2 on my 3 works great too. Haven’t experienced any of the nightmare scenarios I’ve read about here or on Facebook. Knock on wood.
