Sat Nav updates

[Keith Lester]

I have a 63 plate A6 that currently running sat Nav from the original SD card from 2012 - part number 8X0 919 884. 
looking around, there are many SD Cards available but I imagine that I can only use the original PN but the latest level , which I believe to be 8X0919884L 2018. 
Any advise would be gratefully appreciated

Part numbers will change. You could speak to Audi to see what the current part number is. Or alternatively have a look on eBay and ask a few sellers.
