Honestly, I prefer the map on the 5131G as I have spent my whole life in Asia and Europe. Also there is snow on the 5131G, a feature which I feel adds to the contrast of colours. I would be thrilled to be allocated a 5231G even if I do not receive it soon. I would be grateful as I can imagine the list on this watch. Which is why I would be happy with the new 5230P if I am unsuccessful with the 5231G.
