Just to re-iterate, seeing as this thread has revived!...

2. C-MAP support.

3. Touchscreen interface. OS X is an incredibly sexy UI, and very intuitive. However, when you're being tossed around on deck, and you're trying to select menu items on your 8" touchscreen, with Musto sailing gloves on, it can be a tad tricky! A full-screen finger-friendly interface a la MapTech Offshore Navigator would be so useful. Also, slightly larger icons would be useful

4. A zoom / chart select toolbar where you can either increase / decrease zoom, or select larger scale / smaller scale charts of the current location.

GPSNavX has already included a lot of the features requested by users. These are the ones that I honestly think are missing.

C-MAP: could we hear from GPSNavX what's involved (technically: the SDK; financially:licensing from C-MAP, were they willing; etc.)?

Tossing around on deck: if it's that bad, and you're single-handing most of the time, then you need a seriously waterproof [sunlight-readable in a storm? :-)) ] larger screen, in other words, expensive, and you might as well go for a proprietary solution with a marinized unit from Furuno, etc. As we 've seen, the sunlight-readable, water-resistant screens come at a price that puts you in range of the proprietary units, touchscreen or no.

I do think mirroring a below-decks display to a usable cockpit screen is a fine solution (after all, you can replace parts of a setup like that rather than the whole unit if something fails) but we're still getting into major Euros/$$/££/CHFfor that.....
