Car navigation won t turn on? What should I do if the car navigation system can t be turned on?

General navigation does not need to install any key to boot, because navigation is connected to the key of the acc, as long as you play the daoacc file, the version can be turned on, can not be turned on, the problem of the machine, the protocol or the core module is broken, find the manufacturer to repair it;

If your machine is garbled, press the reset button to try;

If you have an electric pen, you can disassemble the machine, check the power cord behind the machine and the power cord of your original car, red (acc), yellow (constant electricity) these two wires, to see that there is no electricity, the power cord of the machine is out of power, just see if the power cord is broken, reconnect. If the power cord of the original car is out of power, it is the safety burned.

The reasons for this are as follows:1If the screen is black as soon as you turn it on, it may be that there is a problem with the navigation host, and the navigation host program cannot be started when you boot it.

2.Because there is a white screen when the boot is turned on, it turns to a black screen, which preliminarily indicates that there should be no problem with the power supply of the car circuit, and it is powered on, but it cannot be started. 3. If there is a problem with the navigation screen, the screen will be black, and the navigation map voice prompt should also be there, and it should not.

1: The battery feeds, the starter consumes a lot of power supply, and the power supply voltage drops when starting the engine, resulting in navigation not working. The generator is damaged and the battery cannot be charged, the battery has no power to replenish, the voltage drops, and the capacity decreases;

If it is a powered car navigation, it may be a short circuit in the circuit and the resistance wire needs to be replaced. If it is a car navigation system without power, the voltage may be unstable, and this kind of need to go to the maintenance center to repair the voltage.

Update 3-5 small video screens every week, mainly for household appliances, electronic technology, circuit principle analysis, electronic DIY some practical things to show everyone, so that everyone can learn together, grow together, progress together, and learn a skill!

It may be out of power, try charging it overnight, and if it doesn't respond when you connect the external power supply, you can only flash it.

The car navigation system can't be turned on:

Black screen on startup: In most cases, the battery is exhausted, many people have a habit of using the navigator is, in order to facilitate the use of the navigator, often do not turn off, the use is to let him default standby, which is convenient to open the speed of the navigator, but the navigator is in the standby state, it will slowly consume the power of the battery, and the power will not be turned on naturally.

After powering on, the screen is powered on, but the screen stays on the boot screen or the white screen is not messed up, and the book can enter the system.

This situation generally occurs in people with strong hands-on ability, most of the situations in a navigator are caused by the failure of the brush APP or OS system, it will become the so-called brick of the fierce hidden, if you have a strong branch on hand to accompany the hall to make the software of the machine, just brush the machine again, if not, send it to the merchant to brush it.

1. Charge the navigator, charge the navigator according to the usual charging method (it is normal to charge normally, you can rule out the possibility of the wrong charging method), wait for 3-5 hours (if it is out of power, you need to charge to activate the battery), and then press the power button to see if there is a response.

2. Failure problems, including damage to the power button, damage to the charging head, damage to the battery and damage to the internal hardware of the navigator.

3. The power button is damaged. When pressing the keys, see if the keys are different from usual, whether there are signs of looseness, if there is no abnormality, you can temporarily rule out the possibility of damage to the boot button.

4. The charging head is damaged. Observe the charging head, charging cable, and charging port to see if there is any abnormality.

5. The battery is damaged and the internal hardware of the navigator is damaged. In both cases, you will need to go to a repair point and check before you can confirm the specific situation.

Consider that the navigation software needs to be upgraded and the navigation software is corrupted. Just reinstall the upgrade. It can't start, it may be a motherboard problem, so I can only send it for repair.

Car navigation is composed of a simple mp4 and navigation software. The car navigation system is powered by the car's internal battery. When the battery is almost empty, the navigation will not start working.

Normal charging is sufficient. Navigation runs for a long time, the internal storage space of MP4 is too small, there are too many fragments, or too many caches, which will cause navigation to fail to start. Just clean up the cache.

Consider MP4 failures. Just replace it. Car Navigation Extended Material:

Car navigation is able to help the user accurately locate the current location and calculate the trip based on the established destination.

The driving aid equipment of the instrument that guides the user to the destination by map display and voice prompt; The operation of car navigation mainly relies on the global positioning system; Car navigation is mainly composed of chips, antennas, processors, memory, and screens.

There are many factors that affect positioning and navigation, Shanchang invites you to try the following methods to check and confirm:

1.Influencing factors such as magnetism, metal phone cases, magnetic brackets, etc.

Metal or magnetic materials will interfere with and shield GPS signals and affect the reception of signals. If you're using a metal case, magnetic case, magnetic stand, or magnetic chuck, we recommend that you remove it and reposition it. For example:

If the center console of the car is interfering, it is recommended that you change the position and move your mobile phone to the window and other places to check.

2.Location: Piedmont simulation software impact.

The location simulation software uses a virtual location, so when it is opened, it will affect the real positioning results, and if the location simulation is not exited normally, it will always show that the GPS signal is weak.

3.Reasons for geographical location.

1) Towering buildings, dense buildings, roofs, and walls will affect the reception of GPS signals and lead to inaccurate positioning. We recommend that you enable Wi-Fi or move to an open area.

2) The signal is usually poor in tunnels, viaducts, mountainous areas and other heavily obstructed places or high-speed driving scenarios, and the GPS signal can be recovered when you go out of the area. If the GPS signal has been poor, it is recommended that you try restarting your phone.

4.Whether the position switch and location permission are enabled.

Please check whether the navigation software has permission to read the location information. Steps: Open the phone settings, enter permission management in the search bar to enter the permission management interface, click the app that cannot locate the navigation, and turn on the location information permission.

5.Please check if your phone settings are correct.

1) Please make sure that the mobile network connection is normal and the location information is enabled in the drop-down notification bar.

2) Please confirm that the location service settings of your phone are correct. Steps: Pull down the notification bar, press and hold the location information icon to enter the location service interface, click to improve accuracy, and enable Wi-Fi scanning to improve the accuracy of network positioning.

If the above methods still do not solve your problem, we recommend that you back up your data in advance (third-party applications such as QQ and WeChat must be backed up separately) and bring your purchase voucher to a nearby Huawei Customer Service Center for testing.

Make an appointment for service. Boarding service.

Repair spare parts** inquiry.

You can take a look at whether this navigation is out of power, you can connect the wire first, see if it can cause the screen to light up, if it still can't be turned on, you can only choose to repair it.

There should be a particularly small button on the navigation panel, with a logo starting with the English letter R, which is equivalent to the restart button of the computer, and you can press the button once.

You can press the switch to do a reboot, and there may be a short circuit on some circuit board. If it's a battery, you can also replace the battery.
