Summary: This is a great tool, one of the best GPS i have, you can go from your car to your boat thanks to the features of this GPS, all USA city maps came with it and also the USA inside lake charts, no need to buy any extra maps. XM radio...with a subscription you get XM music, is great ..!
Summary: Versatility of the 378 with it's XM weather was the reason I bought it. I haven't used on the lakes and rivers in Minnesota. I've used the automobile GPS and it works great. The screen size is perfect for my use.
Summary: The 378 is first and fore-most a marine chartplotter. With the exception of radar, the unit has every feature found on the much larger units we use on-board a 32' research vessel. Display is readable, even in direct sunlight; screen regeneration is very fast.
Summary: The unit arrived in good order. Am still working on the operating manual. This GPS has many options to set up and different ways to connect to a vehicle. It will take some time to take advantage of all it has to offer.
Summary: Loaded with lots of information. Would be easier to use if touch screen. Marine lake detail did not include my favorite lake which is the second largest in its State (44,000 acres). Bummed since I could not find a list of the covered Lakes at the Garmin site.
Summary: I purchased a Garmin GPSMAP 378 in June 2006 and paid about $1300 for the unit and some extra maps. Really liked the unit until I went to update it in Apr 2010. The only map updates available from Garmin are over two years old. Garmin will sell you this old update for $70.00.
Summary: This is a great product displays road maps and marine charts.Voice turn by turn driving instruction. Bad weather ? No problem you can subscribe to XM and also have live Radar Overlay which is great for navigation.Fishing is a breeze with the built in fish sounderand while you're Waiting to catch the...
Summary: I love my gps. It does everything I need it to. It is very expensive, but youknow that before you buy it. I travel a good bit, and use it daily. You do need to read about it and learn all the benefits, and use them.
Summary: The 378 is great gps, suitable for both car and motorcycle. It can so many things with many options or you can ignore all the complex features and set it up for simple operation. The high resolution screen is easy to see if in bright daylight and its larger than most other units.
