- Many such thin clients simply do not include enough memory and/or resources to store all of the map information which may be necessary for navigation over an extended route, for example.
- a PDA or cell phone might have some fixed small amount of memory, say 8 megabytes.
- navigation or position determination in any desired area may require much more than that limited amount of resources.
