The Family Traits
The major differences between the Magellan Maestro GPS models are in the display sizes. All the devices have a color touch screen that acts as the interactive interface, but the 5100 device has a 5-inch screen, the 4700 model has a 4.7-inch screen, while the 4370, 4350, 4250, 4220, 4210 and 4200 devices all have 4.3-inch screens. The 3250, 3225, 3220, 3210 and 3200 only have 3.5 inch screens, but the 3200 is often considered one of the top three affordable GPS systems.
All devices in the family use the SiRFstar III integrated chipset and this provides the fastest GPS acquisition on power up, as well as when coming out of GPS black spots. There are several modes available for route selection such as fastest time, shortest distance, least or most use of freeways, and avoid toll roads modes, but these are common to all GPS models. While the number of POI in the map database may vary depending on the model, the POI icons are interactive. Upon choosing them you get to see the name, address and the phone number of the services stations, restaurant or hotel/motel, and a route to the same point. The smart detour feature allows automatic detour suggestions if faced with sudden slow traffic.
"Say Where" is a useful feature on some Magellan Maestro GPS models, and it allows the devices to speak out the street name on each turn. While the Quick Spell feature lets you enter destination names with very few touch inputs. Look at this article to see what can be expected with the best touch screen devices.
