Remember when finding your way around meant buying a map and learning how to read it and then of course, there was figuring out how to fold the stupid thing back up.

Well technology has changed all of that, today a little box mounted on your dash will not only show you how to get somewhere but would if you turn by turn directions.

There is not much chance of getting lost in are technologically advanced world. Little devices like the Garmin 478 will make your next vacation trip much more pleasurable.


  • built in marine detail charts of the U.S.  Coastline
  • Preloaded with city navigator
  • Detailed street maps of U.S., Puerto Rico and MEXICO
  • W A A S enabled
  • 12 parallel channel GPS receiver
  • 3.8 display with 480 x 320 resolution


If none of the above was enough to make your vacation sweeter the Garmin 478 also comes with six million points of interest. Never worry about finding a hotel, convenience store, restaurant or attraction again.

You might have been wondering why you would need marine detail charts of the U.S. Coastline, well if you’re lucky enough to have a boat the Garmin 478 can quickly and easily be transferred from your automobile to your boat. What could be more fun than that?

In some aspects, that Garmin 478 is smarter than we are. It can quickly keep up with the acceleration of your boat or car and can even tell you how fast you were walking in between the two. That is a little eerie if you stop and think about it.

The Garmin 478 is also fast when it comes to acquiring satellite signal.  Not only is it fast but it is very accurate this little baby can tell you what part of your driveway you are parked on.

The unit has an excellent screen size with nice resolution making it easy to see even in bright sunlight. Even with this large screen the unit itself is small and portable a definite plus if you will be moving it from one vehicle to another very often.


On the downside of the Garmin 478 is XM receiver, you would have thought that it would include up to date traffic information. The capability is there however this software is lacking, had it been installed this unit would be a must have.

The proprietary memory is also lacking, you cannot use SD or mini SD and the memory cards from Garmin are a lot more expensive.


The world has changed a lot over the last few years, technology is constantly changing the way we live our lives. Your car can talk to you and you can talk to your computer, so it is only natural that a talking box can give you directions. 

Although these are becoming quite popular the Garmin 478 is still relatively expensive, a new one will cost you around $600.
