Pre-installed soft
The navigation programme, originally installed in the navigator and sold with it, in other words, a set of maps available to the user “out of the box”.
Most modern navigators are equipped with such programs (although the name of pre-installed maps is not indicated for all models). Note that the functionality of complete programs in different models may vary. Most often, these are the simplest maps of the world or the region in which this device is sold. However, there are exceptions: there are models with detailed maps, programs with advanced functionality, etc. Such exceptions are especially common among high-end specialized devices, in particular marine and aviation (see "Scope"). And for some navigators, there may be several options for pre-installed programs and even the ability to select such programs at the request of the user. All these details should be specified in each case according to the manufacturer or seller.
It is also worth considering that the characteristics often indicate only the general name of the cards. At the same time, the same card can be available in several versions that differ in functionality and, sometimes, terms of use (paid / free). However, the main features are basic capabilities, interface device, etc. — usually, are common to all versions. Therefore, by the name of the complete programme, usually, one can quite accurately determine the general capabilities and features of the card's functionality.
Map coverage
The region of the world for which map data is available on your navigation device. Map coverage determines which geographic areas and countries can be displayed and used for navigation on a specific device. Note that coverage may vary in detail and content: some preset maps may contain detailed information about roads, landmarks, shops, gas stations and the like on a global scale, while others are often limited to the basic road network for a particular country or region .
To make it easier to find a suitable solution for map coverage, registrars can be divided into several subcategories based on territoriality:
Europe,
Africa,
the whole world.
