How to unplug the DVR Xiaomi: all the ways for models 70Mai, MiVue and Redmi

Xiaomi DVRs are some of the most popular on the market, thanks to a combination of price, quality and compact sizes. But sooner or later, owners are faced with the question of how to carefully remove the device from the glass or panel without damaging either the mount or the surface of the car. The problem is complicated by the fact that the manufacturer uses different types of fixation, from standard double-sided tape to magnetic holders and 3M adhesive bases.

In this article, we will discuss 5 proven methods to unstick Xiaomi DVR (including the 70Mai Dash Cam, MiVue 796, Redmi Smart Dashcam and others) without leaving any traces on the windshield. You will also learn what to do if the glue is still there, and how to properly prepare the surface for reattachment. It is important to consider that improper removal can lead to loss of adhesion of new Scotch or even cracks on the glass due to uneven tear.

Why Xiaomi DVR is difficult to unplug: types of fasteners

Before we get to the instructions, let's figure out what type of fixation you're dealing with, and it depends on the choice of removal method:

• 🔹 Two-way Scotch is the most common option in budget models (for example, 70Mai Lite or Redmi Smart Dashcam C100). Usually it is a tape based on acrylic glue, which eventually loses elasticity and "stick" to the glass.
• 🧲 Magnetic fastening – used in quick-removal models (such as the MiVue 796) is not the problem with the glue, but with the possible oxidation of magnets or dirt between surfaces.
• 🏷️ glue base 3M — It is found in premium devices (for example, 70Mai Pro+). This glue is characterized by ultra-strong adhesion and requires a special approach.
• 🔧 Vacuum sucker is rare, but it's used in some versions, and the key here is not to damage the rubber membrane when you remove it.

If you’re not sure what type of mount your model has, check the documentation or inspect the base of the registrar.For example, the Xiaomi 70Mai Midrive D06 uses a combined mount: magnet + double-sided tape to fix the holder.

Preparation for removal: what will be needed

To unplug the Xiaomi DVR without consequences, prepare in advance:

Plastic card or mediator (for scotching)

Hair dryer (construction or household) for heating glue

Flour or dental floss (for "sawing" of the base)

Isopropyl alcohol (70% and higher) or glass cleaner

Soft cloth without pile

Glass scraper (plastic, not metal!)

Microfiber wipes

-->

If you have a magnetically fastened model (such as the MiVue Juefang), you may need WD-40 or silicone lubricant to treat magnets. For 3M glue devices, you’d better use specialized tools like the 3M Adhesive Remover, but you can replace them with acetone (caution — it can damage the tinting!).

Important: Do not use metal objects (knives, screwdrivers) to smear the recorder - they scratch the glass and can damage the anti-reflective coating. Also avoid aggressive solvents (such as white spirit) on plastic cabin panels.

Method 1: Heat-off peeling (for double-sided scotch and 3M glue)

This is a good way to do it for most Xiaomi models that use adhesive base, and the principle is simple: when heated, the glue becomes elastic and moves away from the surface more easily.

1. Heat the base of the recorder with a hair dryer, keeping it at a distance of 10-15 cm The temperature should be 50-60 ° C (not higher so as not to damage the plastic of the case!). Heat evenly, driving the hair dryer in circles for 1-2 minutes.
2. While the glue is warm, gently tuck the edge of the recorder with a plastic card or a mediator. Don't force it -- if it doesn't, warm it up again.
3. Once the edge has moved, slowly pull the device parallel to the glass, continuing to heat. Don't pull up, so you risk tearing off some of the glue.

If the recorder doesn't unstick, try the thread method: floss under the base and saw it with glue while heating the surface, a technique that is particularly effective for broad-base models (such as the 70Mai Pro Plus).

💡

If there is no hair dryer, you can use hot water: moisten the cloth in water (60-70 ° C) and apply it to the base for 5-10 minutes. The effect will be weaker, but the glue will soften.

Method 2: Removal of magnetic mounting (for MiVue and 70Mai with quick removable)

Magnetic holders (such as the Xiaomi MiVue 796 or 70Mai Omni) are usually easier to remove, but there are some nuances: the main problem is the oxidation of magnets or the entry of metal dust, which makes the connection too strong.

Instructions:

1. Clean the surface of the magnets with a dry cloth. If you see rust, use WD-40 (spray on a napkin and wipe the magnets).
2. Take the recorder body and pull it up with a little bit of scrolling (clockwise) and don't pull it too hard, because you can damage the power connector.
3. If the magnets are "rimmed", heat the holder with a hair dryer (as in the first method) or wrap it with a cloth soaked in hot water.

After removal, check the magnets for metal chips, which can interfere with reliable fixation when re-attached. Use a dry toothbrush or compressed air to clean.

Method 3: Removal of glue residues after registrar removal

Even if you've carefully unstuck the device, there's often traces of glue on the glass or panel, and they need to be removed, otherwise the new mount will not hold well.

Important: Never use metal scrapers or knives - they scratch the glass. For persistent contaminants, it is better to repeat the cleaning procedure several times than risk damaging the surface.

⚠️ Warning: If there is a greasy trace on the glass after cleaning (for example, from vegetable oil), wipe it with acetic solution (1 part vinegar to 3 parts water). This will remove the film and prepare the surface for a new fastening.

Method 4: Removal of vacuum suction cup (rare models)

Some Xiaomi DVRs (such as the 70Mai Midrive D07 in the early versions) were equipped with vacuum suction cups, the main advantage of which is the ease of installation, and the disadvantage is the risk of falling off when temperatures drop, to remove such a suction cup:

1. Find a vacuum lever or button on the holder (usually marked as OPEN or RELEASE).
2. If there is no lever, gently tuck the edge of the suction cup with a plastic card to let air through.
3. After removal, check the rubber membrane for cracks. If it is torn, the suction cup will not hold - you will need a replacement (article for D07 - VAC-07-RB).

Vacuum suction cups are sensitive to contamination. Before re-installing, clean both the suction cup and the glass with an alcohol solution. Do not use a suction cup on a dusty or greasy surface - it will last no more than a week.

What to do if the registrar does not unstick: emergency measures

If none of these methods worked and the device needs to be removed urgently (for example, to sell a car), resort to extreme measures.

• 🔥 Strong heating - warm the base with a hair dryer at maximum temperature (80-90)°C) within 3-5 minutes Risk: plastics of the shell may be deformed.
• ❄️ Freeze -- put ice wrapped in a towel on the base for 10 minutes, and the glue becomes brittle, but the glass can crack from the temperature drop!
• 🔨 Mechanical impact - if the recorder is no longer a pity, put it in a screwdriver (not from the glass side.

⚠️ Warning: If there are microcracks left on the glass after removal (they look like a spider spider in certain lighting), do not install a new recorder in this place. Vibration from the device can lead to cracks growing.

FAQ: Frequent questions about the removal of video recorders Xiaomi

💡

For models with 3M glue (such as the MiVue 796), always use the original 3M Adhesive Remover cleaner - it will not damage the glass and completely remove traces. Analogs (acetone, white spirit) are risky for tinting and anti-reflective coating.
