Fixing DVR Xiaomi 70Mai: how to glue correctly and for a long time

The Xiaomi 70Mai DVR is a popular solution for fixing road accidents, but its effectiveness depends on the quality of the installation. Incorrect attachment can lead to a device falling during movement, distorting the angle of shooting or even damaging the windshield during dismantling. In this article, we will examine all the stages of installation, from selecting the adhesive base to checking the reliability of the fixation.

The 70Mai model (including the Pro, Dash Cam 2 and Omni versions) features a compact body and magnetic mount that requires careful first installation, and we analyzed the feedback from owners, the manufacturer’s technical recommendations and the experience of the auto electricians to create a step-by-step guide without risks. It is important to note that the process is different from the mounting of recorders from other brands (such as Garmin or BlackVue), which use vacuum suction cups or other types of double-sided tape.

Selection of the installation site: where to glue the registrar

The optimal position of the Xiaomi 70Mai is behind the rear-view mirror, but not all cars allow you to place it there without interference.

• 📏 Viewing angle: the device must capture at least 120° roads ahead, including markings and verges, for wide-angle models (70Mai Pro 140°) allowable shift closer to the center of the glass.
• ☀️ Lighting: Avoid areas where solar glare hits the lens (especially for versions without a polarizing filter).
• 🚗 Availability: the recorder must not interfere with the driver's view or the operation of sensors (e.g. cameras) ADAS radar).
• 🔌 Wires: if you use wired power, lay the cable along the rack or under the ceiling skin, so as not to spoil the interior.

Owners of Xiaomi 70Mai Omni (with circular shooting) often make the mistake of placing the device too low, which leads to the hood being hit in the frame. The optimal height is 5-7 cm from the top of the glass. You can check the correct location using a test recorder: turn on the recorder, take a picture and assess whether important elements (traffic lights, signs) are closed.

Surface Preparation: Why the Registrar Falls Off

More than 60 percent of the Xiaomi 70Mai crashes are due to improper glass preparation. The manufacturer completes the device with 3M VHB double-sided tape, but its adhesion depends on the purity of the surface. Even invisible contamination (fat, silicone lubrication, dust) reduces the strength of the attachment by 40-70%.

Step-by-step cleaning of glass:

1. Remove old traces of glue or tape with isopropyl alcohol (concentration 70%+). Acetone or solvents can not be used - they damage the tinting and anti-reflective coating.
2. Apply a degreaser (like Liqui Moly Silikon-Entferner) to the glass and wipe with a lilac-free napkin. The movements should be circular, center to edge.
3. To remove static electricity, use an antistatic spray or wipe the glass with a dry microfiber.
4. Do not touch the treated surface with your hands – even fingerprints contain fat, which impairs grip.

If the glass has a tinted or anti-reflective coating, check the compatibility of the glue. Some films react to aggressive adhesives, forming bubbles. In this case, it is better to use a suction cup mount (for example, Xiaomi 70Mai Suction Cup Mount), it is less reliable in frosts below -15 ° C.

Fixing the registrar: step-by-step instructions

The Xiaomi 70Mai comes with a magnetic mount with double-sided tape pre-applied. Don't remove the protective film from the adhesive until you install it! Unpack the mount and follow the following steps:

1. Apply a magnetic platform to a selected location on the glass and circle it with a marker (e.g. Edding 800) to avoid bias when fixing.
2. Take the protective film off the tape and gently press the platform against the glass. The effort should be uniform - press on all corners for 10-15 seconds.
3. Do not turn on the recorder for 1 hour - the adhesive should be polymerized. At temperatures below +10 ° C, the waiting time increases to 2 hours.
4. Mount the recorder on the magnetic mount. Make sure the charging contacts match (for wired models).

For additional fixation, you can use Loctite 406 glue (applied on the edges of the tape), but this will make it harder to dismantle. The alternative is heat glue, but it loses its properties when glass is heated in summer.

Common Mistakes and How to Avoid Them

Analysis of forum reviews (4PDA, Drive2) showed that users often make the following mistakes:

Pay special attention to the first switch. If the recorder starts to warm up (the norm for 70Mai is up to 50 ° C when writing in 4K), check if the case blocks the vents. Overheating can melt the adhesive base.

💡

If the recorder is installed correctly, but the image is shaking as you move, check the rigidity of the mounting, sometimes it helps to additionally fix the power cable to the rack of the car with the help of screeds.

Dismantling the Registrar: How to remove without damage

To remove Xiaomi 70Mai from glass can be two ways: mechanical and thermal. Mechanical is suitable for 3M VHB tape, thermal is for cyanoacrylate-based glue (for example, Loctite).

Mechanical method:

1. Subdense the edge of the scotch with a plastic card or mediator.
2. Pull the mount parallel to the glass (not up!).
3. Remove the glue residues with alcohol or a special cleaner (Autoglym Intensive Tar Remover).

Thermal method (for persistent glue):

1. Heat the fastening with a hairdryer (temperature 50-60 ° C).
2. Move the platform carefully to the side.
3. Clean the glass from glue residues without abrasives (for example, a Microfiber Madness napkin).

⚠️ Warning: Do not use metal scrapers or knives, they scratch glass and anti-reflective coating. If the glue does not lend itself, contact the car service: masters use professional tools (for example, Permatex Gasket Remover).

Alternative fastening methods

If standard Scotch is not suitable (for example, due to severe frost or uneven glass), consider alternatives:

• 🧲 Magnetic mount with suction: suitable for Xiaomi 70Mai Midrive D06. Minus - can fall off with a sharp braking.
• 🔗 Rubber belts: lock the recorder behind the rear-view mirror, not spoiling the glass, but limiting the angle of view.
• 🛠️ The dashboard bracket: attached to the ventilation deflectors. Requires drilling (not suitable for rental cars).
• 🧴 Moment Montage: Reliable, but Undamaged.

It is important for Tesla or Autopilot car owners to avoid metal mounts, which can interfere with radar systems, and then use transparent gel cushions (such as the Gel Pad for Dash Cam) that are metal-free.

💡

If you often change between cars, choose a suction cup mount or rubber belt, for permanent use, you prefer double-sided 3M VHB tape or Loctite 406 glue (given the complex dismantling).
