===Navigation Data Standard (NDS) ===
The [[Navigation Data Standard]] (NDS) initiative, is an industry grouping of car manufacturers, navigation system suppliers and map data suppliers whose objective is the standardization of the data format used in car navigation systems, as well as allow a map update capability. The NDS effort began in 2004 and became a registered association in 2009.<ref>{{cite web|url=http://www.nds-association.org/wp-content/uploads/02_NDS-20120919-Short_History_of_NDS.pdf|title=Short History of NDS|access-date=2012-11-05|archive-url=https://web.archive.org/web/20160304084643/http://www.nds-association.org/wp-content/uploads/02_NDS-20120919-Short_History_of_NDS.pdf|archive-date=2016-03-04|url-status=dead}}</ref> Standardization would improve interoperability, specifically by allowing the same navigation maps to be used in navigation systems from 20 manufacturers.<ref>{{cite web|url=http://www.nds-association.org/partners/|title=NDS Partners, NDS Association|access-date=2015-02-13|publisher=NDS Association|url-status=dead|archive-url=https://web.archive.org/web/20150213192303/http://www.nds-association.org/partners/|archive-date=2015-02-13}}</ref> Companies involved include [[BMW]], [[Volkswagen]], [[Daimler AG|Daimler]], [[Renault]], ADIT, [[Aisin AW]], [[Alpine Electronics]], [[Navigon]], Navis-AMS, [[Robert Bosch GmbH|Bosch]], [[DENSO]], [[Mitsubishi]], [[Harman International Industries]], [[Panasonic]], Preh Car Connect formerly [[TechniSat]], PTV, [[Continental AG]], [[Clarion (car audio)|Clarion]], [[Navteq]], [http://www.navinfo.com/en/index.aspx Navinfo] {{Webarchive|url=https://web.archive.org/web/20200801115841/http://www.navinfo.com/en/index.aspx |date=2020-08-01 }}, [[TomTom]] and [[Zenrin]].

====Media====
The road database may be stored in [[Read-only memory|solid state read-only memory (ROM)]], optical media ([[CD]] or [[DVD]]), solid state [[flash memory]], magnetic media ([[hard disk]]), or a combination. A common scheme is to have a base map permanently stored in ROM that can be augmented with detailed information for a region the user is interested in. A ROM is always programmed at the factory; the other media may be preprogrammed, [[download]]ed from a [[CD]] or [[DVD]] via a [[computer]] or network connection, or directly using a [[card reader]].

Some navigation device makers provide free map updates for their customers. These updates are
often obtained from the vendor's website, which is accessed by connecting the navigation device to a PC.
