Garmin Montana 600 Not good for marine navigation
Garmin Montana 600 for Marine Navigation is not good for Marine navigation. If using the routs it decides which order you go in not the way you select. This can be dangerous as you might want to navigate around an a hazard and it overrides by going 1st to the closest waypoint. Furthermore you cant jump a waypoint on a route. Rubbish. The old 276 and 498 were much better.
