I read many posts on this great forum and few others and will share my experience in hope that folks who have the same or similar tomtom device find it helpful.

Its regarding the Toyota Yaris 2008 built in TomTom TNS400.

Very surprised that tomtom home is still selling and offering maps for this old tomtom for UK it offers the latest 1135.12487 - no meta available.

I have settled for UK map version 1110 via the TTActivator-1.20 (Thank you for this amazing tool). I tried to download 1135 to 1115 but message popped up and said no meta so only 1110 has the meta.

Map kind/Generation: arm9-mnt, Map Version 1110, Map country: United_Kingdom_and_Republic_of_Ireland

Its a lower end satnav so think above is the lowest map it can handle.

I downloaded the map to a folder and then transferred to the unit also downloaded the Safety cams direct to the unit and they were automatically activated but for map I selected and clicked activate on lower right on installed content tab.

Last thing was postcodes so version 1110 and chose just Great Britain.

All seems to be working inside, will test outside later in the week.

Did it work for you ? Doesnt work for me eastern europe 1gb.
