On my canyon bike i use the karoo with an Garmin Speedsensor (010-12103-00) because the GPS signal is sometimes to weak (or the speed on the karoo shows 30-34 kph (for example) by constant speed, especially when there is no free sky (under trees etc.).
On my new bike i have a second garmin sensor but the following problem: the sensor is 'connected' with the karoo - but the speed depends from the gps-signal. The only difference between my old and my new bike is the garmin sensor.
Can somebody help me to fix the problem ? What i want is that the speedsensor on my new bike works like the one on my new bike!
