Is there a handheld color GPS with C-map cards?

[Jonas Lonnroth]

I've been using a Magellan NAV6000 for years. It uses C-map which I prefer
to Garmin Bluechart. However, slow redrawing of screen and monochrome
presentation makes me look for a more modern replacement. A large screen
would be a great plus.

Thanks
