Specifications Mark 2 Tourer V: what you need to know before buying

Model Mark 2 Tourer V It is positioned as a universal car TV, but its capabilities go beyond standard functions. Let's look at the key parameters that influence the choice:

• 📺 Diagonal and resolution: 10.1–15.6 inches (depending on version) with support 1920×1080 (Full HD). It is important to check compatibility with the resolution of your signal source - for example, a rear view camera.
• 🔌 Interfaces: 2×HDMI, 1×USB 2.0, AV-in/out, antenna connector DVB-T2. Missing DisplayPort, which may be critical for connecting some laptops.
• 🎵 Audio system: built-in speakers 2×5 W + output to external speakers. There is enough power for the interior of a car, but large minibuses will require an amplifier.
• 🔋 Food: works from 12V/24V (car cigarette lighter or direct wiring). The maximum current consumption is 3.5A, which must be taken into account when choosing a fuse.

One of the key advantages of the model is support automatic switching to rear view camera when engaging reverse gear. However, this requires proper connection to CAN bus vehicle or using a separate trigger wire. If this functionality is important, check with the seller for the package contents: the basic version often does not have a cable for connecting to CAN.

Parameter	Meaning	Notes
Processor	Rockchip RK3128	Legacy architecture, but sufficient for multimedia
RAM	1 GB DDR3	May slow down when playing video and navigation at the same time
Built-in memory	8 GB eMMC	~5 GB available to the user (the rest is occupied by the firmware)
Format support	MP4, MKV, AVI, JPEG	No support HEVC (H.265) - important for modern video files

It is worth noting that Mark 2 Tourer V not equipped with module Wi-Fi or Bluetooth as standard. To connect wirelessly, you will need an external adapter (for example, TP-Link TL-WN725N), but its compatibility depends on the firmware version. Before purchasing, check with the seller whether your specific device supports OTG function for connecting peripherals.

Connection Mark 2 Tourer V to the on-board network: diagram and errors

Incorrect connection to the car's electrical network is one of the main reasons for TV breakdowns. Let's consider two main options: through the cigarette lighter and direct connection to the battery.

Option 1: Through the cigarette lighter (simple, but not reliable)

The fastest way, but it has limitations:

• ⚡ Maximum current of the cigarette lighter - usually 10A, but in some cars (for example, Lada Granta) it is limited 5A. This may cause the fuse to trip during peak loads.
• 🔌 The quality of contact depends on the connector. In cheap adapters, heating often occurs due to poor soldering.
• 🚗 The TV will turn off when the ignition key is removed (if the cigarette lighter is powered from the ignition switch).

If you choose this method, use fuse cable 3–5A, built into the plug. For example, model Xiaomi Roidmi 3S has protection against short circuit and overheating.

Option 2: Direct connection to battery (optimal)

For stable operation, it is recommended to connect the TV directly to the battery through a separate fuse. You will need:

• 🔧 Cable with a cross-section of at least 1.5 mm² (for currents up to 10A).
• 🔥 Fuse 5A in a holder installed as close to the battery as possible.
• 🔌 Shutdown delay relay (optional) so that the TV does not turn off immediately after turning off the ignition.

⚠️ Attention: Never connect the TV to CAN bus or other vehicle signal wires without using optical isolation. This may cause malfunctions in the machine's electronic systems (e.g. ESP or ABS).

To connect a rear view camera, use a separate video input AV-IN. If the camera is analog (composite signal), you will need an adapter RCA → 3.5mm jack. For digital cameras (e.g. with BNC) you need a signal converter.

Check battery voltage (should be 12.6V–14.4V)

Install the correct fuse rating

Insulate all connections with heat shrink tubing

Check polarity before switching on

Test idle operation (no load)

Firmware update: step-by-step instructions and risks

Firmware Mark 2 Tourer V may be required to fix bugs, add support for new formats, or improve stability. However, the process is fraught with risks: if there is an error, the device may stop turning on. Let's look at two official update methods.

Method 1: Via USB drive (recommended)

For this you will need:

• 💾 Flash drive format FAT32 up to 32 GB (it is better to use a new one to avoid reading errors).
• 📁 Firmware file with extension .img or .upg (download only from the official website of the manufacturer!).
• ⚡ Car battery charge is at least 70% or connected to a charger.

Instructions:

1. Download the firmware and unpack the archive. The file must be named strictly update.img (rename if necessary).
2. Copy it to the root directory of the flash drive (not to a folder!).
3. Insert the flash drive into the slot USB TV (usually located on the side).
4. In the TV menu, go to Settings → Software Update → Local Update.
5. Confirm the start of the process. The TV will reboot 2-3 times - do not turn off the power!

Method 2: Via SD card (alternative)

If the USB port does not work, you can use microSD-card (up to 32 GB, FAT32). The algorithm is similar, but the firmware file must be in the folder /update/ on the map. This method is slower, but more reliable if there are problems with the USB controller.

⚠️ Attention: If after the update the TV is stuck on the logo or does not turn on, try resetting the settings to factory settings by holding the button Menu on the remote control when turned on. If this does not help, you will need to reflash it via UART (for advanced users only!).

Download firmware only from official sources. Files from torrent trackers or forums may contain viruses or incompatible software versions. For example, firmware from Mark 2 Tourer IV not suitable for model V - this will lead to an error ERROR 0x102.

What to do if the update is stuck?

If the update process has stopped at 0%, 50%, or another value for more than 10 minutes:

1. Turn off the power to the TV (remove the plug from the cigarette lighter).

2. Wait 30 seconds and turn it on again.

3. If the device does not start, try repeating the update from another flash drive (preferably a different brand).

4. If this does not help, contact the service center: you will need to reflash it via JTAG or memory replacement.

Typical faults and repair methods

Even with careful use Mark 2 Tourer V may fail. Let's look at the most common problems and options for eliminating them.

1. Does not turn on (no response to the power button)

Causes and solutions:

• 🔋 Eating problems:
  • Check the fuse in the cigarette lighter plug (it often blows during power surges).
  • Measure the voltage at the TV input with a multimeter - it should be 12V–14.4V.
  • If there is voltage, but the TV does not respond, there may be a malfunction of the power supply (replacement of capacitors or microcircuits is required LM2596).
• 🔌 Power button malfunction:
  • Try turning on the TV using the remote control. If it works, the problem is in the microswitch on the panel.
  • Disassemble the case and check the soldering of the button (the contact often comes off).

2. No picture (the screen is black, but there is sound)

Possible reasons:

• 📺 Backlight problems:
  • If you see a dim image on the screen in bright light, the backlight LEDs or inverter are faulty.
  • For repairs, you will need to disassemble the matrix and replace the LED strip (for example, with SMD 3528).
• 🔌 Signal source connection error:
  • Check that the correct input is selected (HDMI1, AV etc.) in the TV menu.
  • If used HDMI - try a different cable (cheap cables often do not support Full HD).
• 🖥️ Firmware failure:
  • If the image disappears after the update, flashing is required (see previous section).

3. Sound doesn't work

Diagnostic algorithm:

1. Check the volume level (sometimes it gets lost after the update).
2. Connect headphones to the jack 3.5mm - if there is sound, the problem is in the speakers or amplifier.
3. If there is no sound in the headphones, the audio codec may be faulty (microcircuit WM8960).

To replace speakers, impedance models are suitable 8 ohm and power 5–10 W. For example, Visaton FR 10 or Dayton Audio PC83-4.

Setting up picture and sound for your car

Picture and sound quality in Mark 2 Tourer V highly dependent on the correct settings. Let's consider the optimal parameters for automotive use.

Image Settings

Recommended settings for day and night use:

Parameter	Day (sunny)	Night
Brightness	80–90%	40–50%
Contrast	60–70%	50–60%
Color temperature	6500K (cold)	4500K (warm)
Sharpness	50%	30%

To reduce screen glare, use anti-glare film (for example, 3M Vikuiti). It reduces reflections by 90% without compromising color reproduction. You can also install the TV at an angle of 10–15° to the vertical - this will reduce direct sunlight.

Sound settings

In a car, it is important that the sound is clear, but does not drown out the road situation. Optimal settings:

• 🎛️ Equalizer:
  • Increase the mids (1–3 kHz) for better speech intelligibility.
  • Reduce bass frequencies (60–100 Hz), so as not to create vibrations in the cabin.
• 🔊 Balance:
  • If the TV is mounted at the front, move the balance slightly forward (+2 dB to the front speakers).
• 🎧 Connecting external speakers:
  • Use an amplifier with at least 50 W per channel (for example, Pioneer GM-A3702).
  • For bass, connect the subwoofer via RCA-output (if it is in the model).

If you hear background noise in the cabin (for example, from a car generator), install surge protector to the TV power line. Suitable model Schurter FMAB NEO or its analogues.

Connecting additional devices: camera, navigator, game console

Mark 2 Tourer V supports connecting various gadgets, but there are compatibility nuances. Let's figure out how to integrate the device into the car's multimedia system.

1. Rear view camera connection

For the camera to work correctly you need:

• 📹 Analog camera:
  • Connects via AV-IN (yellow connector RCA).
  • If the camera has a connector BNC, use an adapter BNC → RCA.
  • To automatically shift when reverse gear is engaged, connect the camera wire to +12V, which appears when reverse gear is activated (usually the pink or purple wire in the tail light harness).
• 🎥 Digital camera (AHD or CVI):
  • Requires a signal converter to CVBS (for example, KTB-4CH).
  • Connects via HDMI (if the converter has such an output).

If the camera image is blurry or noisy:

• Check the integrity of the cable (especially if it is laid next to power wires).
• Use shielded cable with ferrite beads.
• In the camera menu, disable the function WDR (high dynamic range) - it can create artifacts on cheap models.

2. Connecting a navigator or smartphone

There are three main ways:

1. Via HDMI:
   • Suitable for smartphones with support MHL or SlimPort (for example, Samsung Galaxy S5).
   • An adapter will be required (eg Google Chromecast or Miracast set-top box).
2. Via USB (in OTG mode):
   • Works only with some firmware. The mode must be turned on on the smartphone USB debugging.
   • Applications like: CarWebGuru or MirrorLink.

Wireless connection:

• Install Wi-Fi-adapter (for example, TP-Link TL-WN725N) and use DLNA or Miracast.
• The delay (lag) can reach 0.5–1 second - critical for navigation.

3. Connecting a game console (PS4, Xbox, Nintendo Switch)

To do this you will need:

• 🎮 Power supply:
  • Set-top boxes consume 50–100 W, so you can’t connect them through the cigarette lighter - use an inverter 12V → 220V power not less 150 W.
• 📺 Connecting to a TV:
  • Use HDMI-cable no more than 3 meters long (longer ones may not transmit 4K-signal).
  • If the image blinks, try turning on the mode in the set-top box settings RGB Limited.
• 🔊 Sound:
  • For surround sound, connect the set-top box to the amplifier via HDMI ARC or optical output.

⚠️ Attention: If after connecting the set-top box the TV starts to overheat, install an additional cooler (for example, Noctua NF-A4x10) to the processor heatsink. Mark 2 Tourer V does not have active cooling, and under high loads (for example, in games) the temperature may exceed 70°C, which leads to throttling (automatic decrease in performance).

Cleaning and care: how to extend the life of your TV

Car TV is susceptible to dust, moisture and temperature changes. Proper care will help avoid damage.

1. Cleaning the screen and case

Recommendations:

• 🧴 Screen:
  • Use a lint-free microfiber cloth and a special monitor spray (for example, Karcher Display Cleaner).
  • Do not use alcohol or acetone - they will damage the anti-reflective coating.
• 🧽 Housing and vents:
  • Remove dust with compressed air (a can) or a soft brush.
  • To remove grease stains, use a damp cloth with a small amount of soap solution.
• 🔧 Connectors:
  • Clean your contacts HDMI and USB with a cotton swab dipped in isopropyl alcohol.
  • If the connector is loose, bend the contacts with a thin screwdriver (carefully!).

2. Protection from moisture and condensation

Humidity is the main enemy of electronics in a car. Tips:

• 💧 If the TV is installed in the trunk or minibus, use silica gel bags (moisture absorbers).
• 🌡️ In winter, warm up the interior before turning it on - this will prevent the formation of condensation inside the case.
• 🛠️ If the TV was exposed to flooding (for example, after rain with an open window), immediately turn it off and dry it with a hairdryer on cold air mode for 12-24 hours.

3. Storage and transportation

If the TV is temporarily not used (for example, in winter):

• 📦 Store in original packaging or in a polyethylene foam case.
• 🔋 Once every 3 months, turn on the device for 10-15 minutes to prevent the capacitors from discharging.
• 🌡️ Avoid storing in an unheated garage at temperatures below -10°C - this may damage the liquid crystal matrix.

If “dead pixels” (constantly burning dots) appear on the screen, try “treatment” using the program JScreenFix. Run it for 10-15 minutes - sometimes this helps to “unblock” stuck subpixels. However, if the defect is associated with physical damage to the matrix, it will need to be replaced.

FAQ: Frequently asked questions

Is it possible to connect Mark 2 Tourer V to the solar panel?

Yes, but must be used charge controller with exit 12V and a voltage stabilizer. Solar panels produce unstable voltage (from 14V up to 20V), which may damage the TV. Recommended controller EPEVER MPPT 10A with voltage limiting function.

Also make sure that the panel power is sufficient: Mark 2 Tourer V consumes up to 40 W, so the panel must be at least 50 W (including conversion losses).
