What do these different symbols mean: a tick in full green, and a tick in light green?

The colors are explained in the lowest 6 lines of the chart.

Thank you so much. After years of using your (and your predecessor's) Compatibilty charts on this excellent site, somehow I misled myself this time! I should'n't have been so hasty to post my question.
The colours of the backgrounds to the ticks and crosses have no relevance to the colours in the lowest 6 lines of the chart (which only apply to the Equivalence area and Maps nos area of the chart). It's just unfortunate that green backgrounds are used for the ticks...I guess that an alternative suitable and distinctive background colour is difficult to find in the palette!

What should I click to download NAV2 maps for a XXL ?

Fixed, must be high-level-u

Sorry Fredderf I missed your reply

It is all explained on the chart. Study the top part of the chart to decide what features you're looking for...once you've decided on a partiular map, look at the bottom part to find the map number and you'll see the map designation on the far left. If you want a map with all the extras...high-level-u

Thanks for the info 'what's the difference' between nav3 and nav3 - Strasbourg? Thanks.
