Cellstar front and rear drive recorder CSD-790FHG, used item. This is an auction for the main unit and SD card only. The internal condition has been inspected and maintained, and it is a fully functional product. In my subjective opinion, the exterior condition is also good and I think it's a beautiful item. For this listing, both internal batteries have been replaced with new ones. Therefore, settings are retained, startup is quick, and GPS positioning is also fast and comfortable. Also, all deteriorated parts, including supercapacitors, have been inspected. If there are deteriorated parts, even if the device operates normally, functions such as recording during a collision may not work, and it may not function when it matters most. For those times, I recommend a properly maintained drive recorder, even if it's used. The software has been updated to the latest version (0.4.4). The GPS data has also been updated to the current latest version, December 2025. A new 64GB microSD card has been prepared. This allows for four times the recording time of a standard (16GB) card. A new high-quality HI DISC SD card is included. (CLASS10 speed 90MB) How about this for those whose main unit has broken down? You can simply replace the broken main unit with this one and use it. ＜Notes＞ ※ Immediate purchase is preferred.
