TomTom .itn files... which device?

[Johnny]

Hi

My TomTom 930 has just decided to die on me and needs to go back for repair... I need it for the TiTT 3 tunnel run on Sunday morning as i have the itinerary loaded on it.

I was thinking of buying a TomTom One as it's pretty cheap and just using that until mine comes back. But after looking online it seems that certain versions don't allow you to upload .itn files.

Does anyone know which versions will? Or which model above the One in the range will?

Any help and advice very much appreciated!

Cheers,

Johnny
