As for the failure of reason, experts say, many products are clearly identified in the technical requirements for the positioning accuracy of detection is lower than the actual technical indicators; some are equipped with the GPS Power supply Adapter failure; even the product has not been interference suppression processing. These reasons will not only result in inaccurate results GPS Navigation, Radiation may also cause other pollution on human health hazard. Positioning capability is not reliable If many Chinese car GPS navigation is not accurate because there is due to China Car Navigation Industry still in its infancy, the product modules, chips use Can not ensure the quality of products, which in GPS navigation technology has been very well-crafted the United States should not have any problems.

In general, some manufacturers of genuine map to genuine memory card and body encryption map, while equipment products are marked with signature and activation code. The market, more than one card diagram of the machine, basically pirated map products. More exciting, rushed back to automotive supplies information station “”
