Diligence quality first
Hualingan latest Audi A1 car DVD navigation system evaluation
Hualingan car navigation systems as the industry 's most innovative automotive companies , uphold innovation, beyond the concept of a highly tailored to their owners , non-destructive in-car navigation systems, this new Audi A1 car navigation set it to 7-inch HD display , car dvd player the same footprint size , 7-inch screen with a super- narrow border of fashionable Audi A1 will show most vividly , clamshell design adds full dynamic.
Reserved lossless upgrade the original car CD in the true sense
New Audi A1 car DVD navigation system with dual display connected entertainment , Hualingan to preserve the essence of the original concept car , the installation of the storage box position and achieve synchronization with the vehicle information display screen vary significantly , car gps DVD players
creating automotive industry precedent.
Hualingan latest Audi A1 car DVD navigation with the original car vehicle information display can be switched by the steering wheel / Navigation System Menu button , you can automatically delay set by the display or navigation screen navigation system power switch is turned off , full of humanity , and can effectively reduce the number of displayed inside the display, increase traffic safety at night . Hualingan latest Audi A1 car DVD navigation seamlessly use the original car audio ,android dvd navigation multimedia sound can be emitted from the original car stereo, do not change the real line non-destructive installation.
Original car style interface height harmony and unity
Highly uniform style of the original car design , simple interface, original car design in black and white tone , simple visual effects, does not produce visual fatigue , the pursuit of stable and efficient A1 car owners, this is the most suitable.
Compared with the traditional navigation , among other features , such as using the system : When pictures, video , DVD player , music and other functions, and fully meet the owners concerned navigation , Bluetooth phone , MP3, MP4, MP5 variety of functions , can also support the original car trip computer display , to cooperate fully with the original car features dynamic fashion , allowing owners to enjoy a safe and comfortable in every way . Also effectively address the needs of the relationship between the driver and passengers in the drive in the music , enjoyable.

Car dvd navigation inertial technology explain ?
Car dvd navigation inertial technology explain ?
Some frequently asks: previously bought a car known as inertial navigation technology , is interesting that not too many cars in the tunnel where the vehicle stopped , the icon shows still moving forward , is that true inertial navigation technology it?android dvd navigation
Re: Actually , GPS has occurred because the signal is weak or inaccurate interference obstacles arise. Not only in the tunnel , we often encounter in downtown , GPS signals are lined with tall buildings refraction, reflection can also occur when the drift .
In addition, the complex viaduct or in the shade of dense track, the signal will be masking live , GPS signal also appears disorders.car GPS dvd navigation system
Currently effective solution to this problem is popular inertial technology on the market.
GPS inertial navigation technology in the field of a wide range of military applications, such as in 1958 , the U.S. " Nautilus " submarine relies on inertial navigation sailing through the Arctic ice in 21 days . Now, the civilian inertial navigation products with precise gyro and vehicle speed pulse projection system , and the formation of vehicle location latitude and longitude information, and locate and map matching .
In the process of moving , always based on inertial navigation signals will be mainly fusion , GPS satellite signal is only secondary correction , when the GPS signal is lost GPS signal or a bad case , the navigator can continue to navigate , good inertial navigation technology can be sustained ten minutes , or even longer.
You said that the situation is the moment you enter the tunnel extrapolated speed , so your car parked it continues to go this inertial technology is not in the true sense .
