Flymap F7/F5
Hi All,
I've searched everywhere on PPRuNe for info, but with no luck.
I'm looking to purchase a GPS, preferably with CAA VFR maps, and after a bit of reasearch I've narrowed it down to either the Airbox Foresight, or Flymap's F7.
Has anyone had any experience of the flymap at all? It seems the better out of the two, but I can't find any information about it, apart from a promising review;

Out of the Airbox and flymap, I decided to try out the Flymap F7.
It came yesterday, I'll post a reply as soon as I've used it in the air, but on first apperances it seems like an extremely slick bit of kit, which responds well.

I have no idea why those raster map based devices have anything other than a north up mode on them.

Because, if a map is to be rotated meaningfully, the text needs to be on a separate layer, so the text remains upright as the underlying map is rotated.
Moreover, the text needs to be not just one layer but each piece of it (e.g. each airspace label) needs to be "attached" to a particular piece of airspace so that as the map is rotated the label can be redrawn in the right place.
And the CAA does not publish its VFR charts in a layered form. They let them out only as a single-layer flat graphic, and that is how Memory Map resells them.
Companies which produce rotatable aviation maps are Jeppesen (whose maps are used on most GPSs), PocketFMS, and I think 1 or 2 others. But I don't think any of the national-CAA-produced VFR charts are available in a layered form suitable for rotation.
There is a separate issue with rotating a graphic in that there is an inevitable loss of resolution - unless the rotation is 90/180/270 degrees in which case you can do it precisely. But I don't think that is the major issue here.

Ah I see. The question you quoted was about resolution, rather than things being upside down.
The resolution issue is solvable simply with a higher resolution image and some half decent anti-aliasing.
Agreed though, you can't turn the text round!
