Your old SD card failed because it got too many writes. Your replacement card will last as long, which is likely plenty of time. The MCU1 memory replacement was also for this same reason, it got too many writes and started losing its useable space, just like the SD card.I considered the SanDisk extreme but don't think it makes a difference as the ultra is also rated for high/low temperatures. The only real difference I saw was the extreme is "gopro approved". I reckon gopro charged plenty for that endorsement explaining the higher price.
As for high endurance it doesn't apply for this application. It just means it is made for many write cycles such as dash cams. Maps are rarely updated and a specific sector on the card is only written every other map update.
But we'll see. If my new card dies I'll be sure to update this thread. Considering the original 2013 card lasted 9 years in Texas heat I'm pretty confident the new one will be ok for a while.
That's why I drop the back of the shelf under the screen. The inch gap helps, milking it as long as possible.Navigation card is only written when there is a map update, so only a few times a year. So write endurance is not an issue, they simply die because of the heat.
Navigation maps are cached for the areas you are driving in. So the display refreshes quickly as you are driving. Also past NAV destinations and likely some route info are dynamically cached. The card is constantly written to and changing.Navigation card is only written when there is a map update, so only a few times a year.

Interesting. I am surprised the failure rate is so high based on age and environmental conditions alone.No. You can try remove the card, it will contain exactly the same data that you have initially written.
Nav card uses squashfs filesystem. From Wikipedia: "Squashfs is a compressed read-only filesystem for Linux."
All caching takes place on the main emmc.
Yep, and the whole point of the large, once a year, map download is that you have the entire area stored/cached on the SD card.No. You can try remove the card, it will contain exactly the same data that you have initially written.

I assume you were actually talking about caching the satellite view maps that are downloaded over the cellular network in the area you are driving in. And yes, those are cached but on the main eMMC. But those have nothing to do with navigation.Navigation maps are cached for the areas you are driving in. So the display refreshes quickly as you are driving.
Yes, and all cars earlier than 2018(?) would have free unlimited cellular data connections to support google earth maps. I am very surprised this is not stored with the other map data. Must have been too slow to read from the SD card on those earlier SD cards, so they used the MCU memory.I assume you were actually talking about caching the satellite view maps that are downloaded over the cellular network in the area you are driving in.

I suspect that Google has conditions on how many satellite tiles can be cached and for how long, and since they use a compressed read-only file system to store the files on the SD card it makes no sense to try to store data that is changing on almost every drive there.Yes, and all cars earlier than 2018(?) would have free unlimited cellular data connections to support google earth maps.

I just finished replacing my Nav SD card today. I tried using a SanDisk 32GB card first and asked Tesla to have a remote tech partition and format it, but nothing happened since Friday and today they responded that I was in the que, but it could take 2-3 days. They had ordered a pre-loaded card for me last week and it arrived late today, so I got it and pulled the MCU again. Nav routing worked again immediately and a 2022 update is downloading now. Unless you can partition and format a standard uSD card for Linux, using the Tesla SD card for $20 is worth it.Is there an update on buying a pre-formatted card at this point?
OR
can i just install a new SD card out of the box and have Tesla remotely initialize and push out the updates to it?
That's great! Curious, did you pull the entire MCU out of the dash or do the HVAC duct hack? Is it bad to remove the MCU? I tried watching a few YT videos but most of them require removing both of the dash trim etc. I'm pretty handy but a bit intimidated with all those clips etc. and something breaking.I just finished replacing my Nav SD card today.

If you ever played with LEGO you can take the Model S dash apart. Seriously, it's simple. All the screws are identical except two which are a different color so easy to tell apart. No need to disconnect any cables from the MCU, just remove dash on both sides and tilt the MCU forward enough to get to the slot.That's great!
