Actually Cuba does
appear in one of TomTom's maps but there is only 19% coverage:[Please Register or Login to download file]
Good find, fredderf!
Unfortunately it appears that no such map has been available with meta code. Bit of a theoretical practice.
Also TT indicates that this map is only compatible with new models (GO 40/400, GO 50/500/510/5100/GO 60/600/610/Mobile Corfu/Rider 40/400).
That's a shame. Would be nice if it would pop up soon for other devices. Especially if TomTom would drastically improve the coverage of Cuba and other areas.
By the way, next to hating what TT has done with the European Zone maps I also hate the new map shop on which you can no longer look for maps starting with your own device model.
