One of my customers got one today. Very impressed with it, but only used it for an hour. Great with notams, havent tried weather but if it is anything like the Met office's accuracy why bother.
Flymap will not accept os grid references. Doesnt tell you where you are in relation to towns cities vrps etcetc.
Looks tacky compared to skymap. Like the idea of route planning on PC and then loading on to box in ac.
Let you know more as get used to it - very expensive though
