Car navigation – the most common problems

Car navigation is divided into two types: pre-assembled, using a cockpit TFT touch screen and independent equipment, which can be fitted to any car. What are the problems?

Car navigation is a great help for the driver. The device makes it easy to reach your destination, also warns you against dangerous locations and speed cameras. Unfortunately, like any electronic device, navigation can fail. Sometimes at fault, sometimes with improper handling.

Independent mobile devices are much cheaper and can be repaired in the event of a malfunction, return to service or simply replace them with new ones. Update or change maps can be done by yourself. Factory navigation is often offered as an optional feature of the car, and you have to pay extra for it – even several times more than an independent device. Many problems also make the upgrade and repair. All this is because few technicians undertake the repairs of such navigation.

Already less than 200 pounds can buy a new device with legal maps. In many cases, they are not only maps of Uk, but also a few additional European countries. Importantly, some manufacturers offer an indefinite update of these maps (in practice, this means 2-4 years, because of the average lifespan of the device).

New car navigation with maps of high-end manufacturers known (AutoMapa, TomTom, Map Map, Garmin) costs an average of 400 to 500 pounds. Of course, you can buy a device without maps (the cheapest cost about 150 pounds) and buy an original map (for example, AutoMapa costs 179 pounds).

Now let’s look at the problems that are associated with car navigation.

Poor map quality in map devices: cheap navigation, with maps installed, in most cases do not impress with the quality of the latter. Branded products are distinguished by poorer voice quality (mainly using speech synthesizers, whose voice is unnatural) and less voice prompts. For example, navigation warns you by speed, dangerous location and speed camera with the same sound (and not a “speed camera notice” or “dangerous place” in branded products). This makes the driver have to look at the navigation screen with every warning to see what the device warns of.

Problem with loading another map: in case of weak maps it is, of course, a purchase of a new map of a reputable manufacturer and uploads it. This can be done on devices that are factory unlocked. It connects to the computer, installs the map in their internal flash memory (usually the navigation has a minimum of 4 GB of memory) and changes the path to the .exe initialization program in the folder with the new navigation. To change the path is a special option in the navigation menu, usually in settings. If the memory is not enough, you can always buy an extra microSD card.

Worse, if the device is not unlocked. Of course, there are ways to upload a different map to it, but this requires changes to the software (the directory names, the init.exe file, and the pathname are changed). In addition, such changes make the manufacturer’s warranty lose.

Difficult touch screen operation: some new navigation, touch screen, works exceptionally hard – initiating an option requires very strong pressure. There is nothing you can do about it, unfortunately, the products of some companies are already there. Their service is just not pleasant.

Touch screen problems: The same navigation screens use the same capacitive screens as typical tablets. The screen can be mechanically damaged, for example, when the navigation is down. In addition, it can also be exploited. In this first case, there is a risk of spillage or cracks. On the other hand, the device will not respond to touch, in some places or across the entire surface, which will completely prevent the device from being used.

In this situation, you have to buy a new touchscreen. Prices depend on the manufacturer of the device and model, the cheapest replacement can be purchased for a dozen pounds, but branded touch screens (digitizers) can cost up to 150 pounds. The best thing to do is call a specialist company (the one that fixes phones). The screen can also be replaced by itself – navigation usually does not require specialized tools to open the enclosure. Many of the cheaper products are not even twisted, only with plastic latches. When replacing the screen, remember to place the tape in the correct place from the display. In many devices, this is a simple process, because the tape is attached with a plastic latch.

LCD display problems: A display is also mounted beneath the touchscreen, which is also connected by a tape to the motherboard. Display failure is most often caused by mechanical injury. The display screen may break or spill. The device may stop displaying or partially display the image. Also, the display bars appear on the display, making it difficult to use the device. The replacement looks almost the same as replacing the digitizer. It is important to properly tap the tape.
