marine & hiking GPS'

JM stated earlier in one of his posts that the 2720 may retain some of the functionality that the smaller Garmin units used to have. I've used an eTrex for several years now and it allows both auto and marine navigation, but it's got none of the bells and whistles of the new models that are out today. I'm bummed because I purchased a Magellan RM 3000T for that purpose, to have for both the car and the boat, but it's practically useless on the boat. I'm still researching and if I find something I'll post it here.

The 2720 has no battery, so it is not useful for hiking or kayaking.

oops

You might want to look at something like GPSMAP 60Cx or GPSMAP 76Cx. They wouldn't be as capable as your nuvi for automotive navigation, but they're waterproof. Maps for driving are sold separately.

If there is a "lock on road" setting it might help to turn it off.

I picked up the Mio C310x today and it has settings for hiking built in. It's not got any "boat" specific settings, but has a setup for use as if you are taking a ferry across water. However, big however, it has a feature that I can't find on most of the more expensive automotive GPS units and that's a track back feature where you can store your track along with waypoints, so if you're going "off road" you can navigate by your track via the breadcrumb trail that it stores. The documentation is vague as to how many tracks it will store, and not sure if the unit goes past the five displayed blank fields or not, but I'm going out this weekend to test it and find out.

So far I'm in love with it!!!
