See commend :
I previously had a Magellan Maestro from 2006 but it recently was stolen. I loved the unit and wanted to replace it. When I found this RoadMate for under $200, I thought I would give it a try. I have several observations:
1. 2010 maps provide a lot better navigation experience than the old ones from 2006.
2. RoadMate has a comparatively huge display that is very appealing
3. RoadMate does not support voice command, while Maestro did/does. However, I was never able to train the voice command system to consistently accept my voice commands. Not only do I not miss this feature, I somewhat prefer not having voice command, obviating any temptation to use it.
4. RoadMate traffic alerts work well, especially since unlimited usage is included at no charge, ever. A small triangle display shows a red border when an incident exists en route or near. There is no audible announcement. One must tap the icon to see a summary. Often but far from always, at least one alternative route will be offered. Simply tap the appropriate "detour" icon to change to that alternative route. One must tap the "Report" button from the summary screen to see a map indicating all incidents. That is slightly tedious, but I cannot think of a more efficient way to do it. The major downside is that sometimes I have run into traffic jams that were not reported. I don't think I can legitimately blame the unit for that. Overall I find the traffic feature useful and intuitive.
5. This unit gives audio directions along with the visual. The audio is much less verbose than the Maestro, and therefore I find it greatly improved. It also is a lot smarter about calculating routes. Older maps often routed me circuitously. This unit almost always chooses sensible routes.
6. Use the auto-expand feature to better select the proper lanes through an intersection, turn, or other situation, such as a freeway split. This is a big improvement over the older models.
7. Overall, navigation is greatly improved. The timing of audio cues is much more appropriate. For example, the chimes indicating a turn come only after passing the last possible wrong turn. Still, they keep up. For example, I have made three quick freeway ramp changes, one after another, and the lane directions were still in time to be followed.
8. Magellan and AAA data bases for "points of Interest" are separate and often must be queried separately to find all "hits". This is only a slight inconvenience, noticeable mostly when using "Search by Name". The "one touch" feature is nice, but actually I have little use of it. If you have many many addresses, it could be very useful. I also like the address book having a lot of new features where a lot of information can be entered. All good stuff.
Overall, I rate this an excellent unit at the price point of under $200. I would purchase it again preferentially over the $350 Maestro. Then again, I don't use voice command.
