Play Android Big Screen 2-Solve the problem of multi-function steering wheel failure and the original car settings APP lost

September 24, 2024

Foreword—-My model is a 2017 Langhang 1.2T. This car did not have a 187 when it left the factory, only a radio.
Under the sales recommendation, I installed a ten-inch Android large-screen navigation.
It can be connected to mobile phone hotspots and can be opened or searched by voice control, similar to “Siri”.
It connects to the Internet and can watch movies, listen to music, and navigate.
It can also be operated with a multi-function steering wheel, driving records, and reversing images have traces.
I highly recommend the 187A or B, but in terms of car intelligence, Volkswagen is compatible with Android’s large-screen navigation, which is also a good choice.

Due to a misoperation, I deleted the original car settings APP in the car, and found that the multi-function steering wheel could not operate the page turning and mute functions of large-screen navigation. I contacted 4S at this time and found that the worker who installed the large-screen navigation for me had opened a business and opened a shop. There will be a charge to go to the store yourself, because there will be a charge beyond the one-year after-sales period. In desperation, he could only do it himself, and it worked.
This article describes restoring factory settings and restoring the vehicle-machine connection protocol. It can solve the problem of losing your own APP, solving the failure of the multi-function steering wheel, and solving the problem of jams that may occur after a long time for large-screen navigation!

Clean up the large-screen navigation APP and delete the original car settings, resulting in the multi-function steering wheel failure.

This APP couldn’t be found in the app store that came with it. I was going to go online and look for it, but the result was like looking for a needle in a haystack.

You can’t use the large screen of the multi-function steering wheel, you can’t switch to the next song while driving, you can’t adjust the volume, and you can’t flip the radio band.

At this time, I realized that I could retrieve the APP by restoring the factory settings.

Restore factory settings directly.

Remember not to power off when restoring factory settings to prevent file loss.

After waiting for a long time, this page popped up. This page is a desktop and needs to be purchased for money. If you don’t buy it, the original interface will be automatically used.

After restoring the factory settings, the original car settings APP appeared. At this time, the car is not connected yet.

Use the password directly to enter the factory settings. You can try the factory settings yourself, go to Baidu, or consult the store staff. The password is 8888.

Enter the factory settings, which is the important function of setting up large-screen navigation. Try not to modify it.

What I need to set up here is the vehicle-machine CAN connection. Several, I try one by one.

Finally I tried it out. This protocol allows navigation to connect with my car.

Let’s take a look at other functions. It’s best not to mess around here, and don’t mess around if you don’t need to.

The vehicle is connected to CAN, and the vehicle parameters are displayed normally.

Check again whether the APP has been affected and everything is normal.

Delete apps that you don’t need to use. This can help reduce the weight of the car!

Let me remind you here that some people left a message in the last article “Playing Big Screen Navigation 1” saying that the Android big screen will get stuck for a long time. If you learn this method to restore factory settings. If you are stuck, you can also give it a try.
