Garmin 278C Question

I have looked at the manual for the 278 and i am still confused Just exactly what does this GPS do that the cheaper models do not do that makes it suitable for offroad/touring riding Hope its not to silly a question.

Here's some advice on that subject:

The main points:
- Bigger map screen resolution shows more map details, more interesting trails, fire roads etc. for the gravel-adventurers
- Better track handling capabilities
- Better user configuration possibilities - you can tailor-make your own user interface/display more than the newer, simplified units
- the x76,x78 series are primarily made for marine usage, where trees and other terrain don't interfere with sat reception
- the x76, x78 series have older technology ( less sensitive sat-reception, more expensive proprietary memory modules )

For offroad/gravel you may want better oversight over potential blind ends and zoom out to greater scales than the ordinary tarmac/main road travellers - thus making the x76/x78 series the better choice. The Zumo 550 has a different customer base targeted - smaller screen and less offroad capable with less user config possibilities. For example autozoom cannot be turned on/off like you can on the x76/x78 series.

Thanks for the info. Had a quick look at the new Garmin 620 as an alternative but cannot believe they have left out tracback on Auto mode. Talk about dumb ass ideas, guess the adventure travel community is not big enough.

It shows a very detailed map that is readable in all wheather conditions. Including direct sunlight.
