Hi, I have a 2013 Mk7 Golf with Discover Pro sat Nav. I wanted to update it, as it was 2013 software. i managed to get 2024 software, unzipped it and moved to an SD card. I then followed the update process and the car seems to say it has the new software but doesn't appear to be using it. Is there anything else which has to be done to install it? The version information now says V03959821DK0350 ECE 2024 . Other information is Part Number 5G0035020H Hardware H41 and software 0179. Does the firmware have to be updated at the same time? I've tried factory reset of navigation unit and powering off and on, but still it appears to not be using the new map. Thanks
