I guess this has been asked and answered dozens of times but I've trawled and found nothing recent.

A few problems.

I'm really struggling to update the Nav system.

1. I only have access to a Mac, on OS 26 Tahoe.

2. Can I use a new card that IS NOT a Skoda original, or must I stick with what I have?

3. The Mac seems to insist on writing extra files to the SD card and messing up the install.

4. Can I simply 'unhide' and delete these files, or is something else needed?

Naturally this has all caught me out with 2 days to go before a big trip - when a Satnag would be very useful ...........

The Skoda Update Portal seems to say any SDS card will do - but it won't ......... unless I've missed something fundamental.

HELP!!

If you have Amundsen MIB2, you will need to use an official SD card. It may pay to get a 32gb replacement card if your original one is only 16gb.

Please explain. I'm O-L-D. 😁😁

What is 'Patch Unit'?

If using anything other than a Skoda original/coded SD card, is it possible to use a card larger than 32Gb? (I have several ......)

Yes

Amundsen maps need to be on an SD card that had the correct ID so it is (or looks like) a genuine Skoda card (or it appears you can hack the Amundsen to accept maps any card) - I use a 32GB genuine card I got off eBay.

Amundsen music can be on any SD card - I use a 256GB SD card.
