Using this OLM dash mount is a breeze. First, pair it with a magnetic mount. Then, simply place your device on the mount, and it'll stay securely in place. When your trip is over, take your device off easily. Remember, the mount and the magnetic mount are sold separately. If you use the Scosche Magnetic Flush Mount, check if your device needs the mounting plates it comes with. Some devices with enough metal don't need them. For installation, you'll have to remove the center dash trim. There's also a self - tapping screw you can drill into the plastic. Look for online guides about dash removal and radio installation for your specific Subaru model. Many vehicles have screws on the sides of the radio mount, so you'll need to remove some trim panels and use socket extensions. To maintain the mount, just clean it with a soft, dry cloth regularly. Avoid using harsh chemicals that could damage it.
