Hmmm that's what I thought :(... I wonder what Garmin was thinking? For my sailing app which is wet (doesn't like touch screen), rugged (gets scratched) and in the sun (needs a transflexive monochrome screen), the Instinct would be a great platform. Have they decided supporting their developers is just too hard??
It may be a price point thing. CIQ might need more as far as memory etc.
And the display would be interesting. Monochrome, not so bad, 128x128 interesting, but the secondary round display, a challenge for CIQ!
Have you looked at Fenix devices? The monochrome bit is up to your app, and with the f5x and plus devices, your app can use the mapping API and pull up device resident maps in your app with your own markers and track.
