This is the worst piece of equipment I have ever purchased. It is not user friendly whatsoever. Impossible to figure out how to use it. Whoever designed this device should be fired. I give it a MINUS ZERO as a rating. When you buy an apple product, it is absolutely user friendly and you look forward to using it. This product, the GARMIN 840, you want to throw it in the garbage. It is also extremely complicated to find out how to even start it. Beyond ridiculous. Stay away from it!
