I've used SKU creator from this forum, and updated my maps to latest.
But I just noticed now I get main speed limit sign in km/h and below there is small mph calculated speed limit.

How do I change it to be mph all the way ? I can't see there being different maps for UK only with mph speed limits, or maybe there is ?
Rlink2 does not have such a functionality itself to change it, so there is no way to do it from the unit, so i must be something to do with the map file ?

Edit:
Solves - I've installed Here maps instead of TomTom maps. tom tom maps work fine
