Problem copying SAT Nav to SD card

[riggssuzuki]

Hi. I have a 2011 A4. I am trying to get the Sat Nav to run from SD card. I tried to copy it using the car system but kept getting failures. I therefore did the copy on my PC. I have checked all of the files are copied across. However when i put the SD card and try to run sat nav from it i just get something about the medium authentication being invalid. WHat is the best way to get the SD card working and how do i do it? Thanks peeps.

I've done it 2 or 3 times, I used a 16 GB SDHC card and it worked perfectly everytime copying to SD card in the car.

How did you actually do it? I pløace the SD card in the slot and used the 'copy to' option but it didnt work. Then i formatted the SD card and tried via the laptop. It copied across fine but wouldnt work in the car.

I just inserted the SD card and used copy facility, that's how I did it.

Is there a specific requirement for SD card type?
