What are the hidden cost if I want to use GPS?
GPS is a toll-free resources around the earth and there’s NO charges to use GPS, but however there will be a cost for the GPS receiver paid to manufacturers. It also requires a software if you plan to use it for NAVIGATION purposes. There are some Opensource software on the net and there’s also some commercial softwares like Mapking, TomTom, Agis or iGO, but most of them are one-time charge and there should not be any hidden cost running a GPS.
