I got this Maylong for dummies unit for my birthday and am very happy with it. It is a little smaller that other units that I have seen, the garmin nuvi for example, but I was surprised that the small size packed such a powerful punch! I recently went on a trip to San Antonio and we got out of so much trouble that we would have come across had we not had a GPS. I have been to San Antonio numerous times but the GPS unit showed us lots of places that I did not even know existed. Startup is a breeze you just press the power button on top of the device. After a 5 second bootup their is a screen with three option. One is View Map which is the most important as it allows you to see where you current location is. The next option is Lets Go which allows you to customize and put in the directions to your destination. The last option is the Settings which allows you to customize the sound brightness, screen, and other options. Ths GPS also has an SD card slot for pictures which I have never used as it would probably drain my battery. The Let's Go feature allows you to put in directions by address, state, city, intersection and street number. I did have a bit of trouble at first because you have to first put in one thing at a time. I found myself having to go back again and again because I made a mistake on the letter or number. This is another frustration is that screen keyboard is to small that I ended up pressing the wrong keys so that the GPS takes it times trying to find the wrong address only to say that their is no such location. Other than that I have to say that unit has saved me so many times. Just this past week some family member came over for a soccer tournament and we had no trouble finding the location to the park, a location that would otherwise have been very difficult to find without the Maylong GPS for dummies!
