Summary: Garmin 440s installs easily and was easy to set up. very simple to use with basic set up. advanced features are available and they are easy to program. The display is a little small but very clear and viewable in bright daylight.
Summary: The unit was just as advertised. I installed it with no problems. The only issue I'm still having is that I can't seem to set it up with my VHF radio to utilize the DSC function. That's the function that allows you to place or recieve a distress call and see your/their position on your GPS screen.
Summary: Garmin is so easy to use I really do not look at the other brands.Customer service is a phone call away with people that really know what their products and are willing to answer any questions. Durable , easy , with great quality.
