I ran into all sorts of difficulties recently when I tried to update my Tomtom Go 610 sat nav. I ended up ringing customer support, and the helpful man explained that the problem lay with the antivirus/firewall built into my Windows 10 laptop. He suggested the easy way to solve the problem was use a Windows 7 computer which I happened to have but was thinking of dumping. He was right, but how do others with just Windows 10 manage?

I ran your issue past TomTom, who confirmed that the problem is directly related to the security running on the machine, rather than the Windows 10 software.
“There are a few elements which can cause problems depending on how the port configuration, https settings and so on are configured,” they said.
“Changing computers is a viable option but it would not really make a difference which OS [operating system] it’s running. People can always make exceptions in their security protocol but this is outside TomTom’s support boundaries.”
The good news is it should be fairly easy to adjust your firewall’s settings to allow your sat nav’s MyDriveConnect computer program to download and install the software onto your device.
“All the communication (inbound and outbound, local and remote) via the following TCP ports should be allowed,” the spokesperson said, adding that the TCP port was most important.
The main communication port should be configured to 80, HTTPS (required for logins, associations and all kind of encrypted contents) should be configured to 443, Internal communication ports should be configured to 3128, 3129 and the web connector port of MyDrive (to communicate with the browser) should be set to 4000.
Hopefully this is helpful and you’ll be able to connect next time you need to update your software without issue.
