At least for North America and Europe, the MG, CS, and CN maps and POI
data all come from NavTeq and are identical across all three products.
Where they differ is in the routing capability. MG only supports auto-
routing on your PC, it doesn't transfer the information necessary for
routing by the GPS unit. CS and CN both do allow you to transfer that
information (there's a checkbox to let you choose when you do the
download), but differ slightly in the quality of the routing data.
CN gives somewhat longer descriptions for some turns that more closely
match the actual wording on exit signs and has some additional routing
data such as time-dependent turn restrictions and the area of London
that is restricted with the "congestion charging" arrangement.
So if your GPS doesn't support auto-routing (Legend, Vista, etc.) then
MetroGuide is the best choice (least expensive and gives you all the
functions your GPS can use). For most auto-routing models (60/76c/cs,
LegendC/VistaC, V, iQue's, Quest, etc.) the CitySelect is recommended
since it supports that feature. But it is more expensive so you'll have
to decide whether the auto-routing support is worth the added cost.
A few models (SP III, SP26x0) can take advantage of the relatively
slight routing enhancements of CityNavigator - but they'll also work
pretty well with City Select. Again you'd have to decide whether the
added functions are worth the added cost.
Note that in some areas, like Australia, there are other differences
between the products, so the above comparison is just for NA and
European areas.
