Do any chartplotter/gps units have these Nobeltec PC software
features?

I'm looking to replace a Garmin 168 chartplotter/gps for use on a
small open boat. Space is limited (the Garmin unit only had a 3.3
inch display, I think I can go as high as 5" or so).

I'm spoiled by the Nobeltec PC software and would like the following
features, which I have not seen in the Raymarine, Garmin, and
Northstar GPSs I'ved used:

• A "predictor line" that shows where the boat will be in 5 minutes at
this spead and course
• The "highway" display on the same page as the map, so I don't have
to switch "pages"
• The boat normally positioned at the bottom of the screen, so I don't
waste half the screen

If anyone knows of any products that do all this (or at least a few of
these things), I'd like to hear from you. Ideally I'd like a color
display, and ideally would like to use the C|MAP NT chips I already
purchased for use with another GPS.

Please post to the list instead of replying by e-mail.

Thanks!
