How to use the LCD TV in the rear of the car

The rear LCD screen is placed behind the headrest of the front seat or the LCD screen behind the armrest of the front seat, which is mainly used for ****, TV, game entertainment and other purposes, which is convenient for rear passengers.

1. Under normal circumstances, the navigation on the car comes with a digital TV function, which can automatically receive terrestrial digital TV signals and watch digital TV programs. However, because the terrestrial digital TV signal is controlled by the local radio and television management department, the equipment cannot receive the digital TV signal at will, and the digital TV set-top box of radio and television needs to be purchased to receive it normally.

2. Therefore, even if the navigation on the car comes with digital TV function, it cannot receive digital TV signals, so it cannot watch digital TV programs.

Check whether the icon of the TV on the main interface of your navigation is lit up like other function icons, if it is dark or gray, it proves that your navigation can't watch TV, if you want to watch, you have to add another TV module on the navigation amplifier board to watch.

1. Because the output voltage of the car power supply is only 12V; The standard input voltage of the LCD TV is 220V, so the LCD TV cannot be directly installed on the car.

2. In addition to the problem of voltage, space is also a problem: the size of the LCD TV is large, the internal space of the car is small, and it cannot accommodate the normal installation and placement of an LCD TV, even if it can be installed, the effect is very poor; At the same time, the question of whether or not you can receive the program channel should also be considered.

3. If the size of the LCD TV is small, and the car space is enough to install the LCD TV, the user can buy a 12V to 220V inverter to invert the 12V voltage of the car power supply into 220V, so as to ensure that the stable input current to the TV can solve the problem of mismatch between the car power supply voltage and the input voltage of the TV.

Power inverter! Through the cigarette lighter 12V to 220V, the wattage is also available. You can just choose a 200-watt one! Generally, the computer city will sell computer supplies and car supplies! Generally sells for about 200 oceans!

It doesn't seem to work, but the one on the car seems to be specially sold.

There is that kind of 12V to 220V transformer, you go to the ingenuity ** on the look,** you play "universal car charger".
