Thank you for viewing. This is a smartphone holder specifically for the ND Roadster from I.L.Motorsport. I am selling it because I am changing vehicles. In addition to the smartphone holder included at the time of purchase, a separately sold iPhone Magsafe holder that fits the ball joint of the mounting base is included. The usage period was 6 months, and there are no missing parts or damage. Installation is basically possible by lifting the dashboard from the passenger side towards you. For more details, please refer to the YouTube video in Japanese that explains the installation process. Regarding the Magsafe holder, it has never come off even when accelerating from 0km to full speed or going over large bumps at high speeds. However, since I was using a Magsafe compatible case, I cannot guarantee its performance with non-compatible cases, so please be aware of this. Please note that I cannot accept price negotiations. Thank you.
