I purchased the Magellan Maestro 4000GPS Navigation System last year while deployed to an unfamiliar city...just to assist me in easily getting around the city. I love it! It is easy to use - even the most technically-challenged person would have no problem with it. Most of the times, (at least 99% of the time) there are no problems with the directions. However, on occasion (1% of the time), when there are new streets, you may find yourself at the wrong place! But, those times, for me, have been very few and far between!
