How can the owners buy a qualified and suitable vehicle navigation product? To this end, we specifically consult a number of senior automotive electronics industry, summed up a few of the experience in the purchase of vehicle navigation, I hope these will help everyone.
Choose navigation skills: choose regular manufacturers produce
As a high-tech product, vehicle navigation system involves many high and new technology fields. A fully functional and high-quality vehicle navigation product needs strong technical and manufacturing strength support. Because the market is in a period of rapid growth, now the domestic navigation products manufacturers large and small have no less than 1000, but most of them are small factory or workshop manual, and the true formal large numbered, which is why many domestic manufacturers, but the quality sampling pass rate of only 30% of the reasons. At present, the scale of the car navigation products manufacturers, Topband good helper, a few songs. Another reason for choosing regular manufacturers is that they usually pay more attention to after-sales service and perfect after-sale service system. Listed companies in particular, at any time to accept the supervision of the public and the Commission, when problems arise, often have the courage to play, rather than shirk responsibility. Small factories because of limited strength, simply can not provide perfect after-sales service, there is no after-sales support, once the product problems, consumers can only bear the corresponding losses.
Select navigation skill two: software upgrades are important

GPS is the core part of the navigation map, generally speaking, most maps need to be updated once a year later. At present, many GPS brands offer free upgrade services, but some companies do not update the map commitment, or to charge fees, consumers must understand clearly when buying.
Select navigation tip three: signal reception capability requires good chips
As a navigation product, what we are most concerned about is its ability to receive satellites, that is to say, the ability to receive signals. The car GPS on the market most will adopt the third generation of SiRFStarIII chip, the chip is in the advantage of the mask and the weather conditions can capture and tracking signal and reduce the interference brought high-rise buildings. In addition, the quality of the chip is directly related to the fast and accurate calculation of the path of good or bad. Going to the same destination, the chips may vary in different ways, and we need the best route
