The BMW navigation system is based on the CARiN
TM
system developed by Philips
Electronics. CARiN
TM
= Car Information and Navigation System.
The BMW Navigation system is a CD driven, on board, active route mapping computer. The
driver can enter a destination through the On Board monitor and the navigation system will
select a mapped route, from the current location, to the destination.
The route maps are stored digitally on a
navigational database CD that is installed in
a dedicated CD drive in the navigation
computer.
The U.S. is divided into 7 mapped CD
database areas ranging from:
Area 1- California and Nevada, through
Area 7 - Covering the South Eastern States.
In addition to the digitized route maps, other information such as hotels, restaurants,
service stations, dealerships, points of interest and local sight-seeing attractions along with
their addresses are stored on the database CD.
The map CDs are currently being updated twice a year. As the updates occur, more streets
and roads will be added. In addition, more local information will be added with regards to
businesses, hotels, motels, local attractions, etc.
