Its not complicated. The developer didnt get bogged down adding useless features. It has been extremely reliable. It needs a $25 Bluetooth dongle that you leave plugged into your car. Used it now for years. It does need one feature : altitude so you can find your car in a parking structure. I think this is a limitation on gps not the app. Not sure though.
