I completely agree with your comments as regards the map colours and layout. I find the roads are too small and thin so you can't, at a glance, see what is going on and the colours are very muted.Had the 2021 update and was charged £40. The colours and presentation of the maps have had a major revamp. In my opinion, a backward step as the presentation is terrible and very hard to follow. No different colours for different class of road so no difference between motorway, trunk, major or minor. Whoever signed it off as 'fit for purpose' needs a real kick up the backside. Had I seen it beforehand I would not have had it installed. Save your money and wait to see if a later version reverts to the previous easy to read format.
