 Installation:

• 1. Cut an Φ52mm (2-1/16") hole in the panel (II) and allow a clearance of 55mm (2 3/16”) behind the panel to fit the gauge.
  
• 2. Remove fastening ring (I), insert gauge through panel from the front. Tighten gauge (III) using fastening ring (I)from the rear.
  
• 3. Connect cables according to the diagram/label.
  
• 4. Connect GPS Antenna to the socket in the back of the gauge and put it in the good position pointing the sky directly.
  
• 5. After turning on the power, allow the gauge to search for satellite signal for 1 minute. The gauge will show speed in knots/km/mph. 

Function Select： “ODO”，“BUZZ” , “UNIT”

• Firstly, please use External Button or use a pin to press the internal button through the back hole.
• Press and hold on the button, then turn on the power supply.
• The LCD will show ODO, BUZZ, etc. 
• You can select the function after releasing the button.
• 1.“ODO”(change total odometer)
• After selecting “ODO”, the LCD will show “5000” (for example 5000 km) , press the button to change the flashing digit from 0 to 99999 to set up the target odometer value.
• 2.“BUZZ”(change overspeed buzzer alarm threshold value)
• After selecting “BUZZ”, e.g. the LCD will show for example “B 80” (buzzer will be on when speed over 80km/h), press the button to change the flashing digit from 10 to 240 to set up the target overspeed buzzer alarm threshold value.
• 3.“UNIT”(switch unit between km/h, mph or knots)
• After selecting “UNIT”, the LCD will show km/h, mph or knots. Please choose your favorable unit.
• 4.How to reset trip odometer to zero?
• Press the button at the backside of GPS speedometer, or the external button. Hold on for 2~3 seconds, then the trip odometer will reset to zero.
