Not sure i know the difference between electronic and GPS?I considered a GPS speedo when I built my gauge cluster, but I settled on an AutoMeter electronic speedo.
It was my understanding that the the GPS speedo can be kinda' weird when you first start the car and you have to find a good spot for the antenna. Those issues might be overblown, but the electronic speedo was cheaper and once it's calibrated, it just works. Calibration just requires you to measure a two-mile long route, activate calibration mode, drive the route, then push a button.
GPS triangulates off of satellites, electronic requires a transducer on the trans or driveline. A nice feature of GPS is you can change to an overdrive, change the gear ratio or tire size without needing to recalibrate the speedometer.Not sure i know the difference between electronic and GPS?
You know he wants the GPS that the insurance companies can track how fast these driving so they can charge you more
