I have three GPS’s - A Tom Tom one, a Magellan 4250 and the Magellan 1212. The 4250 is updated with the latest firmware (4.6). The 1212 I guess is a new model with much better hardware than the previous generation.
Much to my surprise - the routing logic on the 1212 is the best of the lot. For example, both Tom Tom One and the 4250, give me highly suboptimal routing when I ask it to take me to the nearest Wal Mart in Mountain View from Sunnyvale without taking the freeway. I’ve given then identical starting co-ordinates. Only the 1212 gave me directions that were optimal (taking central expressway almost all the way) - and matched the directions from google maps. The 4250 had me take “El Camino Real” instead which would have been “Really Slow”..The Tom Tom one had me take Central expressway half way and then took me to Wal Mart using a mysterious detour.
The 4250 had rev 29 maps while 1212 had rev 33 maps. I think it is unlikely that the map revisions would be a factor in the routing logic, since these area’s haven’t seen new road construction in decades.
Another area where the 1212 excelled was in reception sensitivity. While the 1212 found 8 satellites (marked in green) inside my house, the 4250 kept next to it - found 3, but both were marked in orange and not green (un-usable data) (see posted photo).
I found the smaller screen of the 1212 to be a bonus. It occupies less windscreen area - and hence does not hinder your view as much. It is also lighter and easier to carry around.
