This is a Kenwood DRV-MR740. I used it for about 6 years, and it worked without any errors until I removed it. I am selling it because I am changing vehicles. There are no scratches on the main unit or lens that would affect their use, and they are ready to use. However, although there are no problems with the main unit, the mounting base has deteriorated over time, and I have repaired it myself. The front plastic round part is damaged, so I have repaired it. Please do not touch that part and use it as is. The rear plastic part is also chipped, so I have repaired it. I would appreciate it if you could understand the above situation. Thank you for your consideration.
