How to update an older Tesla Model S or X that only has 3G connectivity to the much faster LTE.

[@thomasnevels5376]

This probably the best UPGRADE ever ... I just did it and it only cost me 109. Thanks for the part numbers and all . .

[@workbirdygaming]

What's crazy is I'm going to Tony's shop next week for this type of repair 😂 crazy scrolling through KZbin and see him wow

[@jackgreenstalk777]

amazing breakdown. I am not even close to qualified enough to do this lol, I just paid $200 to have the professionals take care of mine. cool to see someone who knows what they are doing do it and give all the warnings how you can mess up and safety notes. amazing content 💚

This is the asian counterpart to Rich Rebuilds! Great Work

[@evfixme2816]

Rich has a bunch of great videos, I've learned a lot from him. I'm hoping to help put out additional videos and guides to help S/X owners!

[@PaulAndHarris]

@@evfixme2816 -- This is the first time I see one of your videos and WOW. How the heck did you learn how to do all this? You are brilliant.

[@WatchRichRebuildsChannel]

Great video.

[@evfixme2816]

Here are the parts you need: PCBA, LTE CONNECTIVITY, UBLOX GPS (1054968-01-B) - x1.0 SIM CARD, JASPER (1035347-00-A) - x1.0

Amazing content! Thanks for the deep dive!

Thanks David for this and all your other fine videos and Tesla forum contributions. I've actually gone a different route. I disconnected the wifi and GSM antennas on my 2014 P85 that are located in the exterior mirrors. I'm affected by ChargeGate but (so far) I've dodged more recent "updates" that would have other otherwise nerfed my regen. (Interestingly, I still occasionally pull a two bar GSM signal when parked fairly close to one cell tower). Of course, I've lost Spotify and real-time updates to the Navigator, but there are simple alternatives to these (apps on my ten inch Samsung tab that has cellular connectivity). My only regret is that I didn't disconnect the antennas about three years ago....

[@DavidDrivesElectric]

A trick is to have the car connected to a dummy WiFi hotspot that doesn't have an internet connection. As long as the car is connected to WiFi it will not use the cellular data at all.

[@TESLAPOPOLSCE]

Best regards form Poland.

[@teachingmaterial2011]

Thanks David. Sounds like you got a new LCD screen also.

[@DavidDrivesElectric]

No, that wasn't my car. I upgraded to LET a while ago (also with Tony's help) but we didn't make a video back then. I will do a screen replacement sometimes soon, though.

[@fulldecent]

Could you pls make a video showing how to disconnect all radio connectivity? This is a common question on forums (with lots of judgy answers) and no KZbin videos touch this topic.

[@mohammedbenmsila5559]

Hi can you help me with my Tesla S problem too many errors and doesn’t want to do anything

[@cdoublejj]

some people are disabling the sim cards all together.

[@WatchRichRebuildsChannel]

3g is free from the purchase of the car but now does the LTE SIM card have a monthly fee?

[@AI-Driven-Entrepreneur]

No fee

[@QAWSED2]

Great video David, thanks, how much does the extra pieces needed cost from Tesla

[@456gt59]

Tesla France made the modification for me for 220$ cause I didn't have the time to do it, and they didn't want to sell me the LTE card and sim without doing it themselves... as soon as I left tesla service center my GPS diidn't work anymore, they said just wait 1 or 2 days it will come back! It didn't come back! So I made a new ticket few days later complaining about my GPS! They answered me my SD card has died and now I need to pay 450$ to fix navigation! or 220$ just to check their work again.... I was sure it was not my SD, so today I took everything apart myself, and both my SD cards are perfectly fine! I cloned them and put brand new sandisk not to do the job again. Now I took apart the MCU1 and I can see J38 connected to J6, J7 to J34 and J37 to J5. What is the correct sequence please? J38 to GPS, J37 to J7 and J34 to J5??

[@delschier1419]

I had my 4/2016 Model S with 64K mi screen go black two days ago. There was no way I could re-boot it so I took it to Tesla service today. The said a rebuilt/exchange MCU was $1146 installed. They said I could have the HW2 Infotainment upgrade for $2250 and I told them to go ahead with that. Awhile later they said they couldn't do the upgrade only the exchange because my S didn't have electric trunk lifts and they weren't allowed to do the infotainment update on my car as the version for my car was not available. I wonder if I try to read the chip and do the BGA soldering and fail if they would know the difference. At this point I am waiting to see if they can restore the file system and bring it back to life without spending > $1000. For over two years I have been complaining that the web browser worked when I got the car, then it stopped playing my USB drive, weeks after that it would not re-boot until I removed the USB and now it just plain will not boot. I was surprised however that the autopilot worked perfectly on the way to Tesla service with the black screen.

[@speeddemon945]

Is it safe to assume that that eMMC chip or the whole MCU itself can use different SIM cards from one carrier to another even if someone decides to bring their Tesla outside United States as a Gray Import vehicle?

[@DavidDrivesElectric]

I believe so. The Sim card seems to just a standard one

[@speeddemon945]

@@DavidDrivesElectric the only problem is how to get the old sim card out and inserting the local new sim. 🤔

[@mykelsingleton]

How much would you charge to upgrade my MCU1 to a MCU2 plus LTE and FSD?

[@jonnupe1645]

I have two questions involving the connectivity of the Tesla series. Tldr; do you really need SIM card and how important is it? First one, will removing the SIM card prevent the MCU from working properly? ( ignoring obvious creature Comfort connectivity like GPS map downloads and music streaming). Second question, assuming that, yes the mcu would still work without the SIM card, can Tesla still send out updates or modifications to your Tesla. My gut feeling says no, considering the SIM card is literally for internet connection, but is there a secondary method of connecting to Tesla headquarters?

[@AI-Driven-Entrepreneur]

Yes you cannot swap

[@tristanskylark]

How much?

[@alexissantiago2895]

My cousing car.is already LTE how can he get you tube.

[@Xstevenn]

Great video sir! Tesla is trying to make me change my infotainment for $1500 rather just replace the 3g for LTE ($200) I also am getting my recall done at the same time regarding the slowed memory. They say for some reason the SD card will not read it when they try to complete this process so they are saying it will cost me $1200 to do or just go for the infotainment upgrade ($1500) and it will work fine. I find this to be total BS (excuse my language). I do not want to upgrade my infotainment because we are going to buy the newer X at some point. Do you think they are trying to pull a fast one on me?

[@Fhaldark]

ESD! =)

[@tristanskylark]

All the x’s have 4G

[@chrisashley1550]

Would be dope if you find a way to diy a mcu2 upgrade.

[@DavidDrivesElectric]

It's not difficult to replace the hardware. It's the software part that is not that easy.

[@chrisashley1550]

@@DavidDrivesElectric ok so you would be able to technically switch out the internal components. But the programming is a whole different issue. Heard that part is what takes the longest at the sc. Also heard mcu2 requires a differ wiring harness

[@chrisashley1550]

@@DavidDrivesElectric oh. Just wondering tho if you bought a used mcu2 and wanted to upgrade would Tesla actually install it?

[@bobafett5323]

How much are the parts total?

[@yardeechambers8158]

What’s the cost ?

[@ecsyntric]

i have 3G with free premium connectivity. how do i retain that with LTE upgrade

[@DavidDrivesElectric]

You can just get the 4G module and swap it out. I have a video about it. No need to update the MCU or software

[@matchke7054]

Can I use my own SIM card? Like a data plan from my mobile operator?

[@AI-Driven-Entrepreneur]

No

[@azriaziz]

I have a X 2020 raven thats already on LTE. Is there an exposed sim card slot (like the M3)? Or do i have to open up the MCU as in the video?

[@JonathanShyhJangNyau]

Hi, did you ever figure out if a Malaysian Sim will work on your Model X?

[@azriaziz]

ive got a UK raven X 2020 in Malaysia. is this the location of the sim card if i were to install a local one? at present, LTE doesnt work and im running thru a hotspot

[@DavidDrivesElectric]

Yes the SIM card is on the board. But if you swap it out, you have to updates some settings in the car which I believe either needs root access or Tesla might do it.

[@kimsrensen2982]

No coding needed for the new modem?

[@marcannemariebintner1473]

I have a message telling me I need to replace my SIM card on my model S: what do you suggest?…

[@janbrndum7629]

my sim card is located outside the emcu. which 4g card / module should I use then

[@speeddemon945]

What Tesla do you have if you don't mind me asking.. Can I like pull out the SIM card and use the local sim card of my local carrier in another country?
