Just ok

Bobby, Amazon
31 December 2012
  • Summary: Battery has a very poor lifespan. Good marine and land GPS so it works well on my boat as well as in my car. Screen is more than big enough for my 28 foot express cruiser. Sometimes the display dims out.

Nice GPS

Gary, Amazon
6 December 2012
  • Summary: Can't go wrong with a Garmin product. I received mine with no coastal maps loaded on to it and called Garmin about the issue. They had the maps to me right away and I was ready to go. Their customer service is excellent.

Three years in car and boat

Dave Sea, Amazon
5 May 2011
  • Summary: Got this for my boat 3 years ago and use it in my car too. I interfaced a Garmin echo sounder for depth in my boat and it works great. Very happy with the durability, not much corrosion after from the boat use. Great unit.

great gps

B. Hardy, Amazon
5 October 2009
  • Summary: This is a wonderful gps-very accurate. This is the first one I have used and it is very easy to understand. I wish I had read description better-there are no fresh water lakes included. The value is great for this product.

The added "Lakes" chip

John E. Backman, Amazon
21 September 2009
  • Summary: The 478 is perfect for roads and coastal waters. However, the chip available for additional information regarding inland lakes does not include the Army Corps of Engineers flood control lakes in the Northern PA area.

Garmin GPSmap 478 GPS Receiver

Gary Toth, Amazon
10 September 2009
  • Summary: Much better than I expected...I wish I had it 2 months earlier. The mapping details are excellent...it has street maps & coastal charts. The screen size, coloring & resolution makes it quick & easy to read at a glance. It is user friendly. It is much more than a GPS.
