@widowmaker: TTactivator worked fine here with the map you need (just checked, 1,1 GB worth of files). Check your Internet connexion.

I have trouble getting the map V1155-12874 working on the ARM9-mnt with navcore 7.8 tomtom... cant activate the map... anyone has a solution ??

My internet connection is OK, the problem was antivirus.

Hello @bobracing,

Last known arm9-mnt metacodes are for 1110 maps.

Is there only a metacode for that 1155-12874 map ?
Have a look at full set of metacodes
