Does anyone have an idea how to fix the following problem. I've updated my GO40 to nav4 and when I try to update map v10.30, it starts downloading, then installing untill 100%, then checking and then I get an error that not everything is installed and the map isn't installed. I'm using a fixed cable internet connection, i don't use a proxy, don't have antivirus program running, already removed the temporary map ( so it downloaded again and tried to install it, no luck) I've restarted both pc as go40 a few times. tried different usb ports, and my SD card is the one I've always used for 3 years now.
I hope you guys have some tips or solutions.
Thanks in advance.
