Sat nav update

[JohnCalifornia]

Hi, anyone updated their sat nav with any success.? I’ve tried doing mine today and watched California Chris do it on Yuotube. The only problem is the video is 4 years old and the VW website has changed a bit. Basically I had no luck doing mine. I downloaded the updates but there was no options to do anything with them and it’s just a file that says maps. I double click it and nothing happens. I have a Mac so they can work in weird ways sometimes. When I plug my data card in ftom the Cali it’s just a file that says maps on it. I tried to drag the new maps file onto the file but it just says data card not large enough. I’m giving up tonight on this…….
Thanks for any replies
