Tom Tom not allowing proper postcodes
It's almost new, wide-ish screen but I don't know the model. Trying to program a postcode into it today did not allow the space - well, there was no way of putting the space in. Also it referred to the code as the zip code which of course does not have a space. Okay, wrong map? Showed the route through Essex, and indeed, showed a Union Flag symbol. Just borrowing this one tomorrow, but don't know TT 'OS' techniques.
Any obvious things I'm missing or have TT just goofed with their put in Post Code mode?
