My Urban Rider is mounted in a Active Dock with power supply. After riding in about 15 minutes the GPS signal momentary starts falling out for 5-10 seconds - getting the signal again and then loses the signal momentary again - Very annoying I've tried turning off the power supply and then it seems to be better ??? Someone who got an idea how to fix the problem. My Urban Rider is brand new and already changed once because of the mentioned problem!
