latest release Dec2016 still not solved huge bugs or low features like map dissappearing when Zoom In under 200m scale and low visibility GPS prompt on map I bought it with all extra parts as I intensively use it for much more than simple map. It has video notes geo-integration. However latest release has low readable  too small gps point and too small size poi names and a defective pois selection/disabling mode and hardly to remove/cancel navigation of previous route annoying current map...Even Worse...when Zoom In under 200m scale  Map dissapear unexpectedly...
