The Pioneer FH-770DVD is a car audio system with a touchscreen and various connection terminals. - Model: FH-770DVD 31XX - Brand: Pioneer - Connection Terminals: USB, AUX, RCA - Display: Touchscreen Functionality Confirmed USB, CD, and DVD audio playback have been confirmed. Radio and AUX have not been tested due to lack of environment. The serial number is partially hidden, but I am listing similar items, so you can understand. Includes the main unit and wiring (modified). The disc reader has been lightly cleaned. The surface has also been cleaned, but there are scratches commensurate with its age. The touch panel is also functioning without any issues. As this is an older model, I have checked it as thoroughly as possible, but it is being offered at a low price, so please understand that it is sold as-is, non-returnable, and non-refundable.
