I've been looking at the Garmin Colorado 400c as GPS handheld. I need a GPS for boat use (charts is a bonus and the 400c comes with Aussie charts) but I'd also like it to double as a car nav when I'm off the boat.
For the boat I would like:
- waypoint/route stuff (preferably with VMG (Velocity Made Good) displayed)
- chart display
- download/upload of data to PC
For the car:
- route navigation
- voice directions
I think the Colorado has all of the above except voice navigation, can anybody suggest what else I should consider?
Thanks v much
