Things to keep in mind when buying a navigation device for a car
Car navigation devices are available in many different types and models. In order to choose the best positioning device for the car, what factors should be kept in mind?
Today, with modern technology, cars are fully equipped with convenient systems to serve the needs of human use. Among them, it is impossible not to mention navigation equipment for cars. Current vehicles need to install standard positioning equipment. These devices need to meet the basic functional criteria of vehicle management cruise monitoring.
Types of car positioning devices and specifications
Navigation devices for cars are classified into two main categories, namely standard positioning devices and wireless positioning devices. For each device, technical factors, specifically the specifications will let the user grasp the basic characteristics of the locator. From there, you can choose the right equipment for your car.
For car positioning devices, the basic parameters that the user needs to understand include the chip and frequency band and some other types of parameters. Chip is a part integrated in a positioning device, also known as a GPS chip (short for Global Positioning System — a global positioning system). The principle of operation of the chip is to receive satellite signals and have the function of transmitting that signal. Based on the distance from the car positioning device to about 3 different satellites, one can determine the position of that device on the ground accurately. The acquisition of information from GPS positioning chip is held 2 times / day.
The band on the devices has the function to determine the positioning frequency and the frequency of signals emitted from the device, allowing the accuracy of the device’s position on the ground. Some positioning devices use positioning chip and band with different parameters. Example: Location device TG102E: using Micro SIM; GSM 4 bands 850/900/1800/1900 MHz; X7 car navigation device using GPS chip is MT600 with GPS sensitivity of -159 dBm; VT202 positioning device uses 4 bands 850/900/1800/1900 MHz
In addition to standard positioning devices, a car can also install wireless positioning devices. This device has the advantage of being compact and convenient for use, easy to move in the space of a car. In addition to the specifications of the chip and frequency band, users should also learn and grasp the other specifications of the car such as transmitting capacity, reception sensitivity, battery capacity, battery life …

Features integrated on the navigation device
Firstly, there are features that help determine the exact position of the vehicle, monitor the vehicle’s movement as well as the direction of the vehicle’s movement, the speed of the driver. In addition, through this device, people can also check how many times their car stops parked, how many times the engine is turned off and on. These features ensure the safe management and monitoring of your vehicle and a timely plan to handle emergency situations.
A car navigation device also needs to be connected to a fuel gauge to allow the operator to monitor the fuel level in his or her vehicle. When the vehicle has an incident or is in danger of being in danger, there are signs of being compromised, this device also helps the owner know those warnings and effectively prevents theft. All vehicle data such as the operating route will be updated and stored every 10 seconds and the driver can review it if desired.
Software package included with the purchase of the navigation device
For car navigation equipment, bundled software packages are divided into 4 levels including: FREE (from Free + 1 to Free + 4), CHEAP (from Cheap + 1 to Cheap + 4), BASIC (from Basic + 1 to Basic + 4), STANDARD (from Standard = 1 to Standard + 4) … Depending on your needs, you can choose a suitable package.
Product warranty period
The car locator is stamped with warranty, on the stamp is marked with the warranty month and year boxes and marked in the box. The warranty period of the device is from 6 to 12 months. Some addresses apply a 1-for-1 warranty policy if the product is not as committed by the sales agent (in the case the product is not repaired but only the problem is caused by the manufacturer’s fault). You should prioritize buying products that have as long a warranty period as possible.
Some other note
In order to ensure the installation of a good quality car navigation device, users should note the following points:
Equipment purchased must meet the standards of the Ministry of Transport and the Ministry of Information and Communications. The Ministry of Transport has specified 38 business establishments licensed to trade in car navigation products in Vietnam. Therefore, vehicle users need to find out exactly and go to the right reputable addresses to buy products. In addition, these positioning devices must ensure A — GPS function can work well and stably on the national telecommunications infrastructure of Vietnam.
The device should be stored away from high humidity, avoiding strong impact. You should also check your device’s SIM and network connections regularly to make sure the connection is stable and flexible. One of the causes of an interrupted connection could be lost power. Therefore, the connection to the car battery is also an issue that needs to be checked regularly.
Car navigation equipment (also known as black box) is essential and popular with most cars today. To ensure safety, the driver needs to carefully consider and select a reputable address to ensure the quality of the device.
