TrakNav is the result of combined development between Siemens VDO and CSE.  TrakNav offers Vehicle Navigation, Vehicle Tracking and Job Despastch / Messaging in one superb product.  TrakNav has real-time / historic tracking, dynamic ETA notification and two-way messaging with automatic routing to received addresses.  Fleet operators can now empower their mobile workforce with navigation and their office staff with dynamic ETA's, free text messaging and comprehensive vehicle tracking.

The Pro version of the Siemens Dayton MS 5400 Navigation system has been enhanced to allow the colour screen to be used for two way messaging and automatic routing to downloaded addresses. Route ETA and distance to site data is communicated to the Host system automatically while the vehicle is en-route, keeping operators up to date on the progress of each vehicle.
