FAQ: Which maps can do autorouting on the Quest?

Autorouting on the Quest can be done with a couple of maps.

First of all the (fixed) basemap of the Quest, but the basemap only contains major highways/roads.

Secondly City Select, all versions, which have much better coverage than the basemap. The US City Select 4.00 has limited rural coverage, US City Select 4.01 is much, much better. The European City Select has 100% coverage in a large part of Western Europa and limited coverage in other parts of Europe (version 5 has even better coverage than 4.00, smaller map chunks and also recognises roundabouts correctly).

Thirdly you can use City Navigator, which essentially is City Select with some more road properties (like roundabouts) and designed to be used on the StreetPilot 3. The Quest cannot use the extra road properties, so this essentially is a waste of money in most cases. City Navigator Australia will autoroute on the Quest. It has excellent metropolitan area maps but only main highways in rural areas.

Last, Metroguide US 4 can be used for autorouting on the Quest and has better rural coverage than US City Select 4. It has comparable coverage to US City Select 4.01, but uses maps from a different vendor so coverage can vary greatly between them.

You cannot autoroute on the Quest with map segments loaded from Metroguide Europe or Metroguide US 5, but you can on the PC and load routes from the PC into the Quest. No autorouting at all is possible with other maps, like Roads and Recreation or Worldmap. Metroguide Australia has identical metropolitan area maps and good rural area road coverage as City Navigator Australia, but will not autoroute on either the Quest or PC.

When no autorouting maps are loaded, the Quest will use the underlying basemap for routing, which may result in a route that doesn't quite follow the roads of the loaded maps. The same principle applies to routes which go from one autorouting capable map segment to another. In between the Quest uses the basemap for routing.
