For a number of years, top-of-the-range cars have mostly been equipped with a head-up display as standard. A head-up display shows you all the relevant information in the field of vision and gives the cab a slightly futuristic look. Especially those who have never seen the gimmick will be thrilled. This feature is actually known in aviation. Although you always have all the information in view, you do not have to take your eyes off the road. If you have an older vehicle, you can have a head-up display installed later for little money, thereby increasing safety and comfort.
Functions from a head-up display
Head-up displays will also be HUD displays (or OBD HUD, OBD 2 head-up display) called. The small device projects relevant vehicle data onto a specially machined surface in the windshield, so you always have it in view. The advantage is that you do not have to turn your eyes away from the road, for example, to be able to read the speed or details of the navigation. You will be less distracted and safer with your mobile pedestal on the way. Apart from the driving speed, you can also display additional data, such as fuel consumption and engine speed. You can buy head-up displays for retrofitting for less than 50 Euro. Depending on the model, the devices offer different information and of course it is also more expensive.
Here are the most important details:
- Fatigue protection (long driving without breaks)
- Display of time and date
- Diagnosis of vehicle damage (Infos)
- Output of error codes
- Information about cooling water temperature, tire pressure, battery voltage
- Information about security cameras
- acoustic and visual warnings at too high a tempo
- Distance and total travel time
- Direction and position information
- Information about current and / or average power consumption
- current engine speed is visualized
- Visualization of the driving speed
As you may know, instant sleep can be fatal. To protect you from this, head-up displays have been developed. The HUD, in combination with other monitoring systems in the interior, creates a steering profile during your entire journey. This serves as a comparison pattern until the goal is reached. Both the steering speed and your steering movements are constantly monitored. As soon as deviations occur, your head-up display warns you visually as well as acoustically.
Operation from a head-up display
Do not worry, your new head-up display is easy to install and use. After installation, your HUD display is ready to use. After turning on the ignition of your car, the information will be projected onto the windshield. Depending on which model you choose, you can choose from different variants and switch between display values. Switching takes you, depending on the model, by means of a switch on the steering wheel or via remote control.
Advantages and disadvantages of a head-up display
- easy handling
- Information directly in the driver's field of vision
- compact dimensions
- little need for space
- increases safety while driving
- Eyes are less stressed
- Time savings compared to the reading of the onboard instruments
- completely switched off if required
- no reading problems with dirty windscreen and sunlight
- in combination with a navigation device, space in the area of the center console can be saved
Disadvantages of the retrofit devices
- not usable with polarized sunglasses
- sometimes very expensive
- often Bluetooth function can not be used simultaneously with HUD display
- also with good orientation often difficult to read display
- necessary reflective films often weather and become unsightly
- at night every now and then too glaring
- Ventilation and storage compartments are partly covered
- Start-stop automatic can disconnect the power supply to OBD devices
- Values of vehicle tachometer and HUD differ in some cases significantly
Retrofittable and affordable HUDs have been available on the aftermarket for several years. Used car drivers can thus enjoy the technology. Many devices use the on-board diagnostic interface (OBD) as the data source. However, products with GPS receiver are also available. And even a smartphone can be converted via APP to the head-up display. Common sizes are from 4 to 5,5 inches and so there is plenty of room for many display options. But is the battery voltage and motor load in the field of view really necessary? Everyone has to decide for themselves. Functions such as taking a break after four hours of driving time are quite useful as we find. In any case, it is important to have a good readability so that the readings are not unrecognizable even in the case of a few rays of sunshine. Many apps and devices are at night due to the colors and effects more than pinball machine to recognize which of course has nothing to do with improved security. Especially the mobile phone is in our opinion not very suitable.
It heats up very quickly, which almost always means the end of the battery at values higher than 35 ° C. This requires an anti-slip mat or a special holder so that the smartphone is not a bullet. Next you almost always need special slides on the disc to improve the reflection. The installation is quite difficult and partly incomprehensible because the display should not radiate directly from the car of course. As so often help here the reviews of customers that should be read BEFORE the purchase necessarily.
