Guidance in non-digitized map area, function - GF82.61-P-4001GI

MODEL 163 as of 1.9.01 with CODE (522) Modular control system (MCS) radio USA with CODE (357) Navigation system - additional unit with CODE (818b) Single CD player - additional unit with CODE (491) U.S. version 

When traveling outside of the digitized map area (e.g. company grounds, parking buildings, dirt roads,...), however still within the CD-ROM map boundaries, the navigation processor  switches over to " Guidance in non-digitized map area  " .

The following message appears on the display of the radio and navigation module (A2/56)  :

"OFF ROAD " 

In this case only basic location finding (dead reckoning) with correction by the GPS  data is performed (no map matching  )

After reentering the digitized map area, the system automatically continues with " Guidance in digitized map area  ".

With the aid of the GPS  position the possible roads, on which the vehicle could be located, are determined. However, this can result in temporary delays in the guidance function.
