This is a used Chinese-made portable car stereo (Carplay/Android Auto). I purchased it on November 26, 2023, and used it for about two years, but I am selling it because I am changing cars. The arms in photos 4-5 are unused. The arms in photos 6-9 were only used at the top, and the dashboard mounting parts are unused. As shown in photos 8-9, I cut a part and attached it to a different arm. I cut it so as not to affect the installation of the original arm, but if you are concerned about the appearance, please use the arms in photos 4-5. The included backup camera is unused, so I don't know if it works. I will factory reset it before shipping. It is made in China and is not a Japanese manufacturer's product, so please purchase it only if you are comfortable handling it yourself. I usually ship within 2-3 days, but I cannot ship on Wednesdays, Thursdays, and Fridays due to work.
