Installation was easy, but calibration was anything but easy. I drove in circles a few times, initially I was too slow, but it worked at medium speed. The compass reading drifts for some unknown reason. A search on the internet (which I should have done beforehand) shows that others are also reporting drift. After almost exactly a year it died and I had to unplug it from the bus. The installation location was under the bench seat in the salon, dry and there were no disturbing devices or metal parts nearby. A software update/programming is only possible using a Garmin plotter, no PC software is available. The low price compared to other products is therefore in line with its quality. Conclusion: keep your hands off it!
