How to refit the Android screen of the car's console
Because my car is old, I don't have a large central control screen. When I need navigation, I always put my mobile phone in the air outlet bracket. The magnetic suction bracket sometimes falls off when it vibrates through the deceleration bar. I don't want to stick anything on it. So I just spent hundreds of yuan on a central control Android screen that can insert a mobile phone card.
Now I will show you how to replace the old headunit with new Android screen.
Before installing the large screen, you should remove the original radio. Before dismantling, you should find out the tips for dismantling your car. If you are not familiar with it, you can search the relevant vehicle forum. When you formally dismantle the screen, you can just squeeze it in from the plastic fastener plate of the interior with a plastic screwdriver, and then open it with ingenuity.
First, remove the accessories under the large screen.
Then take out the air outlet and the central control radio, squeezed the whole air outlet with a plastic driver, and then removed the four screws that fixed the radio. After removing the four screws, you could take out the old headunit, which was a big lump and heavy. Basically, the original things were removed.
Next, we start to install a new headunit. First of all, straighten out the cable so you can clearly distinguish what kind of cable it is. On one side of this kind of wire, it can be divided into power line, audio and video cable, and signal line. According to the interface type, they are connected with the headunit, and all the sockets are plugged in regardless of whether they are useful or not. Now the Android screen design is more humanized. All the wires and headunit interface are unique, basically there is no possibility of wrong insertion, if the interface is not on, then it can not be inserted.
Next, GPS antenna and 4G antenna are arranged. In order to avoid signal interference between 4G antenna and GPS antenna, we arrange these two antennas on the A-pillar on the left and right sides. Before wiring, remove the plastic protective shell above the A-pillar. Just squeeze in the plastic clamp through the gap, slightly tilt it and then put the antenna in from the position of pillar a, Stick 3M glue on the metal part of the A-pillar, and then buckle the plastic shell back.
Now I will install my 4G card in this slot and power on the headunit. Let's test it first to see if everything is normal, and then we can carry out the next installation. If it is not normal, the maintenance is convenient at this time. After the car is powered on, the positioning is basically OK, the music sound is OK, the radio is OK, and the map guide is also OK After confirming that there is no problem, we will turn the central control screen back in the order of dismantling.
Since the base of the air outlet is connected with the large screen, there is no isolation sponge for the new base of the main engine air outlet. In order to ensure the effect of the air outlet, I use 3M double-sided adhesive tape to stick a circle of bubble film to the outer ring to prevent air leakage of the air conditioning pipe. Next, you can check the air conditioning pipe one by one according to the order of financial management It's OK to buckle the interior panel. When you buckle it, don't use brute force, but use clever force. Finally, put the plastic buckle in the air conditioner outlet adjustment, and the installation of the large screen is basically completed.
The whole installation process lasted about two hours. Of course, it included the time I spent shooting the video. If I put my heart into the installation, it could be completed in an hour. Since it's dark now, the camera can only be installed tomorrow after reversing. The whole installation process is actually relatively simple. It's just that when you disassemble and assemble, you should use hard work, don't use brute force, you must use skillful force, and do not damage the clip of the car interior panel.
Of course, if you plan to install it by yourself, it is recommended that you prepare a plastic crowbar and a clip commonly used in the car before installation. Do not use a metal driver to install it. It is easy to pry the interior panel out of order. In that case, you will lose more than you gain.
