2015 Model S Nav Map SD Card Swap?

See attached, was quoted $200 for replacing my 2015 MCU1 Tesla Model S Nav maps GPS Micro SD card because my NAV keeps acting up they believe the memory card is going bad.

I know some forum members have done the swap of the sd card, I am struggling to find the best youtube videos on which specific trim pieces I need to remove to get to that 1 side of the MCU exposed enough to swap it out(I think its top right side of MCU1 when its held in place on the dash?)

I imagine I can get another 16GB or maybe better yet just get a 32GB micro sd card. Any recommended best SD cards that will last longer than this one did(6-7 years) before dying out on me and has fast I/O? I guess it really won't matter though because I doubt I will be in this car another 10 years but I guess ideally if I could buy a card now that will last 10 years. Looking to go grab a card this PM. Walmart or Target or Best Buy should have some decent ones.

Any suggestions or videos you know are good are appreciated!

Thinking this card would suffice? Buying now I think.


All that is left is knowing which trim to remove to expose that right hand edge of the mcu unit. Likely will take popping up more trim than I would want to knowing Tesla. I took a bunch of trim off last time swapping from wood to carbon fiber trim so I imagine its the same process again. Wanted to get away with not popping off that top trim and such but doubt I will be able to.

Edit:
Good video to show where part goes:
, just wish I understood the guy haha.

Final update. The SD card I mentioned earlier did work.

Thoughts: I heard newer versions don't have this luckily, but boo Tesla for using a random SD card to store nav data on separately. And double boo for putting it in an inaccessible area easily on the car. Seems very much like a design afterthought. Maybe they expected the SD cards to last longer than 6 years? Idk.

Buttt. Yeah you can get away with the fix by just removing the right hand side trim pieces. Cutting the plastic housing a bit to make that USB slot in the back upper right on the MCU1. Note inside that little slot there will likely be a little tape covering the SD card you will need to break through w your tweezers to push the SD card in to then get it to pop out and pull out w tweezers. I was so worried I would drop the new card trying to put it in too, because it was super hard to angle my head to see it easily and finding a pair of tweezers to get in there was a nightmare too. I had to use some weird acne tweezer kit thing I had that was thin enough to get in to access that SD card slot.

But generally the pictures show it. I replaced the sd card without even moving my MCU. Rather just got through a chunk of plastic housing and touched it up with some HVAC duck tape stuff to handle the air conditioning variable temps.

I had a friend help me copy an img of his existing SD onto my new purchased SD before plugged it into car. But TBH I think you can just plug the SD 32 gig in as is ootb and the car should pickup on it when your on wifi and start downloading nav data onto it. Otherwise you may need to reach out to Tesla service and have a tech remote initiate nav data dump into the new SD.

Hope this note helps someone on the internet do the repair themselves if their nav starts acting up.

After the recent map update I ran into the same issue with my 2016 face lifted model S : Navigation initializing forever!

Before ordering a new SD card, has anyone successfully installed an even bigger than 32GB microSD card, like 64GB or 128GB?
You see, i want to drive the car for some more years!

As a side note:
last fall Tesla replaced the eMMC due to the well known problem!
I do not understand, why they did not also replace the SD card knowing it will fail eventually
 
Jeremy0916. Thanks for the posts. Mine keeps giving an error code MCU_w007 Navigation database not loaded. Connect to WiFi. Doesn’t download anything. I got Tesla estimate for the fix at $285 labor and $20 Micro SD card. Just wanted to say thanks for the posts as I plan on figuring out how to get to it myself.

Replacing the SD cards sounds tricky. I'll check the SD card on my aunt's 2015 Model S tomorrow when it returns from the installation of the new set of tires from 4Wheelonline plus the alignment.

The navigation on my car is not working. I think the SD card is broken and needs to be replaced. I bought a new 16G sd card at Tesla for $20. I'm going to replace this card myself this week. My question is: Do I need to turn off the power before replacing this card ? Thanks a lot for your answers !

Thanks for the info, do you know if there was anything special about copying over the files? i heard its formatted in lunix.
