## Customer Reviews

### ⭐⭐⭐⭐⭐ What a great product.
*by G***R on June 14, 2007*

I love this GPS.The Con's are, it would be great to include inland lakes and ocean on one GPS, did garmin ever think that someone may actually want to take their boat on both or is this a ploy to make you purchase memory and an additional CD. The second downside is the menu's can be confusing and if you are at sea and dont remember what keys to push and are constantly going back to the quickstart guide it become irritating. This issue may not be relevant if you are a prior garmin user or once you have used it for a while and get used to the menus.The Pro's are numerous, for such a small screen it is incredibly bright and easy to read. The detail is extremly good. The battery life is at least 4 to 6 hours if you dim it down.Overall a good product.

### ⭐⭐⭐⭐⭐ Ship to Shore
*by C***T on August 11, 2007*

Yes, all products have a learning curve and the Garmin GPSMap 478 is no exception. This said, the 478 is a very useful tool in any environment. It will guide you to roadway destinations with precision and charm (using the voice feature) and plot a course through nationwide costal cruising. Add on features expand its use to enhanced weather data, depth sounding, fish finding, satellite radio and more. I have only had the unit for a short time and already see it as a great asset in the car and essential on the boat. Coastal cruising here I come!

### ⭐ Quality Control???
*by J***. on August 6, 2009*

I bought the unit NEW from Amazon and received it on Jan 3 2009. The sound didn't work, so after dealing with Garmin's customer service I sent my 12V cord/speaker to Garmin waited three weeks and received a replacement. Still no sound. Garmin then told me to send the unit back to them for replacement. About three weeks after sending the unit to them, I received a replacement, only this one had a loose antenna. The GPS worked fine at first, then it started having trouble finding satellites. Garmin then told me to send the GPS back to them for inspection and sent me a replacement about three weeks later. Now this GPS does not charge. The battery is dead.All of this within seven months of spending close to $700.00 for a NEW GPS and an additional $30.00 in shipping and insurance.
