3. Safety Information
- Do not obstruct your view of the road or vehicle controls when installing the holder.
- Ensure the holder is securely attached to the air vent before placing your device.
- Do not attempt to adjust the holder or your device while driving.
- Keep metal plates away from sensitive electronic devices or medical implants that may be affected by magnetic fields.
- This product is not compatible with MagSafe without the included metal plate. Wireless charging may be affected when the metal plate is attached directly to the phone or case.
- After attaching the metal plate, wait 24 hours for the adhesive to fully cure before use.
4. Setup Instructions
4.1 Step 1: Attaching the Metal Plate to Your Device
For optimal magnetic hold, a metal plate must be attached to your smartphone or smartphone case.
- Clean the back surface of your smartphone or case where the metal plate will be placed.
- Peel off the protective film from the adhesive side of the metal plate.
- Carefully position the metal plate on the back of your device or inside your phone case. For wireless charging compatibility, place the metal plate away from the charging coil area.
- Press firmly for 30 seconds to ensure strong adhesion.
- Important: Allow 24 hours for the adhesive to fully bond before using the holder.

4.2 Step 2: Installing the Car Holder
- Identify a suitable horizontal air vent louver in your vehicle. The holder is designed for horizontal louvers with a thickness of 9mm or more, and vertical louvers of 18mm or more. It is not suitable for circular or irregularly shaped vents.
- Gently push the silicone clip of the YOSH car holder onto the chosen air vent louver until it is securely fastened. The military-grade silicone provides strong friction to prevent slipping.
- Ensure the holder is stable and does not obstruct any vehicle controls or your driving view.
