I bought the GARMIN n?vi 260W to help with work and family travels. After extensive research with Magellan, Mio and Tom-Tom, I bought the Garmin for three reasons. 1) Ease of use. 2) Screen clarity. 3) Amazing accuracy. And no, despite where I live, I have no affiliation with Garmin. I don't even know anyone that works for them. I am in the architectural business.
I have tried several GPSs while traveling with business associates, friends or in rental cars. As such, I have seen them in real world action. All of the devices saved me time and most found the place I needed to be. I could used any of them and been somewhat satisfied.The problem: I am a perfectionist. As such, I want the unit to be the best. So, after using a text-to-speech Garmin GPS unit earlier this year, I knew that was one feature I could not live without when I pulled the trigger on a purchase. Text-to-speech is a must have on GPS. A MUST. If you have never used a GPS, trust me, you have to have text-to-speech. It eliminates the frustration of urban driving and having the non text-to-speech units tell you to turn right in 200 feet, only to find two roads that are 200 feet away and have to pick one and hope it is right.
