This unit will convert ANY Brantz Tripmeter to a GNSS Trip. It calculates a superior three-dimensional ground speed/distance output with an integrated antenna. You can retro-fit to any Brantz or Retrotrip using the wiring provided and place in the vehicle's windscreen. 

This unit simultaneously tracks many different satellites such as the Russian (Glonass), Chinese (BeiDOU), European (EGNOS) and American (GPS) systems, giving connection in the most testing environments. If however satellite links are lost (maybe in a tunnel) then it will calculate and recover the distance lost as a straight line.
 
NOTE: This unit is available as a Plug & Go Item, see the International GPS Bundles
