Sat Nav Cocked Up. Help

[rover220]

Tried updating the nav on SD card with discovercare but at 90% it said there was an error on the card and it failed. Nav now doesn't work obviously.

Anyone got any decent suggestions for a fix?

Discovercare automatically does a card backup before updating so don’t worry the original data is in the backup file on your PC.
I would format the SD card to completely clear it and then run the process again.
If that doesn’t work then post here again.

What he said above....... ^^^^^^^^

moving forwards Get a second SD card so you can always have a spare/backup Navi Card.

I’m afraid a standard SD card will not work with the T6 media, it has to be a VW card as they put some hidden files on it to prevent piracy.

It will look the same if you clone it..

I tried and failed, I guess VW have some pretty decent hidden files locked away on the card somewhere. The last thing they want is a 65 card bring copied and flogged on eBay for 10.
Or perhaps my cloning software wasn’t man enough?

You need a low level block copy clone so that the disk is a bit copy of the original, it will then be a copy.
One way to do this is to make am iso of the original and then "burn" the iso to a new card, that will blow away the new disk and re-image it as a copy. On a PC try using "Rufus" it support most disk types.

It would be nice if it worked, but I doubt it will. Some very clever people have tried to clone cards for marine chart plotters & failed. There's a "hard" serial number burned into the card at manufacture, the satnav/chart plotter does a checksum check before it will load the charts/maps, if the checksum fails, it spits the card out.

I wonder how the original poster got on?

 

[Dellmassive]

i must say i tried a normal copy/paste on the pc and it didnt work...

havent tried the block level copy yet.. seems the OEM card is a 16Gb SD

ill have to get a second 16Gb card and give it a go just for giggles.

having a HARD CODE burnt into the OEM card is a possibility to stop cloning.

@Loz is a techno wizard I think he should try it out for us so we know for sure one way or the other !!

Even if that is the case (and I am not doubting you as TomTom do this with a custom CID) if you make an iso of the original card before you upgrade it you can put it back as it was..

I did the exact same thing. So I popped into my local dealer and told them my sat nav had stopped working. They checked it and gave me a brand new card under warranty. The new card also had the new update.

 

[Pauly]

Do you still have the old card ??

No, they kept it and gave me a new one.
