This is a car audio system made by PODOFO. I purchased it in 2022 and used it until last month. I used it in a Daihatsu car, so it can be installed without modification in Daihatsu or Toyota vehicles. The accessories are as attached. Even if it's not a Daihatsu or Toyota car, it can be used if you modify it, as spare adapters are included. You can also use Android car navigation apps if you install a GPS code. *Accessories are as attached. GPS and a backup camera are missing, so please purchase them separately. If you contact me after purchase, I will share information on where to buy GPS and backup cameras. *I've also included a steering wheel remote control, but it's not working well, so consider it as a bonus. *A converter that allows you to listen to domestic radio frequencies is also installed. *Please note that this product is sold as-is, with no returns or exchanges.
