I have a 2015 Skoda Octavia with the Amundsen unit. Whenever map updates become available I delete the old map from the SD Card and upload the new map. It has always been problem free. However, on trying to upload the recently updated maps I find that they don't work. I tried to revert to the old map which I had stored on my laptop but that won't load on the unit either. I tried VW maps, having read on the Forum that this could be a solution,  but still no joy. I am getting an error message saying "Please insert a data medium with valid navigation data" I'm beginning to think the SD Card might have been corrupted. Can I use a non-Skoda SD Card?

Sadly not. The SKODA card has a security partition. 

 

Did you delete the files or format the card?

 

Deleted it first of all but then, subsequently, formatted it thinking that would clear everything.

Format will clear card.

As Amundsen doesn't has its own memory, it uses just this Škoda card. 

 

You don't need another card or USB stick to upload, although it is possible. It is easier if you remove the Škoda card, connect to your laptop, format it and directly unpack the map archive you get from UPDATE SKODA portal. Simply plug the card next time into Amundsen, should be recognized and work.

 

What is good to know, it is actually possible that someone who has proper medium and software, to write Škoda's CID (this code which protects other card to be used, but only OEM) to another card, bigger, faster, so the device accepts it. I did it for myself, read CID from my OEM 16Gb Škoda card, and used it to put to another 32Gb card. Now both work.

 

Thanks for that. I go through the process of connecting the Skoda card to the laptop and downloading the map to it directly from the Update portal but it's not recognizing it. My technical expertise doesn't stretch to writing Skoda's CID to another card I'm afraid! I'll persevere and see how I get on.

What did you format it to?

This may be a stupid question but did you download the map directly to your SD card or did you extract the files to your SD card?

 

The maps from the portal are compressed files and need to be extracted to the SD card.

Hi. I downloaded the map to my laptop then extracted the data to the SD card. Should have made this clearer.

If its any help I ordered a new (2 year old) card from ebay, I tested that, it worked. I downloaded the update and unpacked it to the Ebay card so I still had mine to fall back to if the update failed or anything. It did work fine. 

 

My point is that the Ebay cheap cards from Czech seller was a genuine card and did work, £20 I think, not too bad - I just didn't want to risk my Nav by formatting my only card. 

 

When I do the next update I'll use my own card so the map info is never more than a year old even if I mess it up. I'll leapfrog card use. 

You may freely format Škoda OEM card. I did it many times.

 

If you're afraid, you can delete all data, instead, but it is slowed and it is consuming life out of your card more then just  a format (it deletes just file allocation table). 

 

OP should try some card format software, maybe it will fix the card. It is also possible that card is faulty, it happens. SD cards aren't the most reliable media in the market.

Could you please explain how to do this?

@MichaelTL, yes, for me it is a black box, but someone I know has access to such cards for different purposes and a device which can write as a CID whatever he wants. It is black, noname card. What is the market price I don't know, but I have given you at least a point of thinking, search in UK if someone offers same.

 

Just to bring this tale to an end, I concluded that it was the SD card itself that was the root cause of the issue and so followed VRS_White_Hatch 

and purchased a new 32gb SD Card loaded with Europe map. I didn't have his confidence to buy it from Ebay and so paid more and got it through Amazon. Outcome is it works perfectly. I'll keep the old SD card just in case it can be revived at any point. Thanks to all.
