Thank you for taking the time to look at my listing. I am selling this item because I sold my car after purchasing it. I was using the S8 series, and although I was initially concerned about it being a foreign product, the operability and screen responsiveness were excellent. The support team also provided thorough assistance until the issue was resolved (via email only). There is no manual, but there are many videos on YouTube about the "X10 series" (the content creators are Japanese), so you can refer to those videos for operation and setup instructions. For detailed specifications, please refer to the "ATOTO" website (as I cannot fully describe them here). The wireless steering wheel remote control "AC-44F60" and two screen protectors are included with the product, and I will also include an additional anti-glare screen protector. I purchased this for a laptop and cut it to fit the screen size (it may be slightly misaligned). Also, when I installed the "X10" mounting bracket and a 1DIN storage compartment in my car, the screw holes of the 1DIN storage compartment cracked. You can still secure it with screws as is, but you can also purchase a replacement 1DIN storage compartment at an auto parts store (they cost around 1,000 yen). The condition of the cracked screw holes in the 1DIN storage compartment is shown in the photos, so please refer to them. Regarding installation, please request installation at a dealer or an installation specialist at an auto parts store. Many screws are included, which I believe is to accommodate installation in various car models, so some screws and mounting brackets may remain after installation. I placed a "cigarette case" next to the photos of the outer box and the main unit for size comparison, but please note that the cigarettes are not included. Also, as the product itself is large, I will ship it via Yamato Transport, with the recipient paying for shipping. When purchasing, please provide your "full name, address, and phone number." I strive to provide smooth transactions, so I hope you will consider purchasing this item. Please prioritize the photos provided and refer to the "ATOTO" website for any details not covered in the description. Please understand the above and agree to no claims and no returns. Thank you.
