Go730 obsolete

Today I connected my Go30 to TomTomHome in order to update navcore. Pop-up window stated because of age and limitations of internal memory I can't update anymore. After clicking Cancel and login I'm getting error connecting to server, error code 403.

How to update navcore now?

Thanks. I've seen that, however there's no setup. Should I just copy all of it to the Go730?

Before proceeding, make sure you do a full backup of your device in Windows Explorer!

Then extract the downloaded navcore *.cab file into your device's root overwriting the current files

Bear in mind that if you're using downloaded maps, you'll need to repatch the system for the maps to be usable
