2015 GTD - Sat nav update possible?


New member
Jul 27, 2020
Hi, I have the standard Discover media unit fitted with 2015 / 16 maps on.
I can't seem to get a straight answer from the web as to whether:

I can download the latest maps from VW themselves onto an SD card & just stick this in the slot in the glove box?
Some sites are saying 3 years of updates, some 5...

I've also read that I must use the original SD card supplied which is no problem but I'd be nervous of messing the currently working (although out of date) SD card up & having no sat nav at all.

If there's a recommended supplier of SD cards the forum approves of & they're not silly money, more than happy to go down this route too.

Thanks in advance for any help here. (Did a search & couldn't see an answer to these specific queries).
