Sony XAV602BT TomTom website error update corrupt
I am trying to update the maps, they are 5 years out of date, I have followed this webpage.... https://uk.support.tomtom.com/app/answers/detail/a_id/18390/~/downloading-and-installing-a-map-on-sony-xav
BUT when you click that link to download the maps, you download them, then when you come to unzip it, you get an error message
Then you can't unzip it, winzip says it's corrupt.
Why??? What's the point of putting links to download corrupt files that won't unzip?
