Standard test and finalization of on-board navigators

One of the essential tests: a full range of professional testing tools
After the product design, the use of spectrum instruments and other professional tools, high standard darkroom and other environment for electromagnetic interference testing and improvement of products. With a top 12 channel GPS signal transmitter, this is the highest industry standard and has an independent source test tool.
Essential test two: road test
And by testing each test process is completed, each product must go through more than 24 hours of practical application test (i.e. road test), highways, tunnels, construction intensive road, crossing edifice viaduct, EMI interference sources in many areas (high pressure line, GSM transmitter station).
Essential tests three: buttons, interfaces, and reset and Hibernate tests
The sensitivity of buttons and interfaces and the reset and hibernation test of the machine is one of the key points in the navigator test. Test the highest standards of the industry on the two aspects of the quantified strict rule: each button must be pressed again and again after 1000-1500 times; all the interface must be more than 1500 times the plug to ensure its stability and compatibility.
And the necessary test four: SD/ TF card, Bluetooth compatibility test
In the SD/ TF card compatibility test session should try to meet the needs of multi brand testing, ensure the test of different capacity. The industry's most stringent standards require that all Bluetooth devices must be compatible with mainstream Bluetooth handsets.
Essential tests five: Flash performance testing
Not rigorous flash performance testing, many products will not be stable, it is easy to not boot. The industry's highest test standards are required in the flash performance test this link, after more than 72 hours of repeated reading and writing, equivalent to 10 years of normal use.
