1. Hook up speedometer power requirements as shown above.
2. Plug GPS receiver antenna into back of speedometer.
3. For best performance, mount GPS antenna with as much view of sky as possible (preferably on the roof of the vehicle). The GPS antenna is waterproof and magnetic.
If the car’s roof is not accessible then mount the antenna on top of the vehicle’s dash with as much exposure as possible to the sky through the window.
(Antenna is able to receive signal through some thin materials i.e. wood, glass, fiberglass, and plastic. All types of metal will block the signal.)
4. Hot start feature is optional. Hooking up the Hot start wire to constant +12volts allows GPS to quickly acquire satellites in less than 2 seconds. This feature saves your
current satellite position within the speedometer enabling it to quickly restore your position on power up.
Please note that if the speedometer has been powered off longer than 4 hours, it could take up to 1 minute to acquire signal due to the satellites moving significantly from
your location. This is normal.
The current draw is extremely low and will have virtually zero impact on a car battery’s charge.
Hotsart wire should be connected directly to battery +12voltage and should remain powered 100% of the time.
