57.42 ? From the GS2 manual, radar calibration section: If this value is 57.42, you are directly feeding GPS radar signal. Ground based radars will display approximately the same values when connected.
Yes a value of 57 gives the same result as most radar guns would. Generally the devices receiving the signal have a calibration number themselves. You can adjust the number on the 250 or the number on the other device.
The bottom line is that the speed that the other device displays should agree with the GPS speed shown on the 250. Starting out with 57 should give very acceptable results.
