Want to add a dash cam to your ATOTO car stereo? This AC-44P2 model plugs right in via USB and turns your stereo's screen into a full-featured dash cam system. It records in crystal-clear 1080P Full HD with a super wide 156-degree viewing angle, so you catch everything happening on the road ahead. The loop recording feature automatically overwrites old footage when the memory card gets full (supports cards up to 64GB – card not included). The really cool part? The video lock function. If something happens, just tap the 'Snap Photo' button on your stereo's screen, and it saves that clip separately so it doesn't get erased. You can control everything and play back videos through the dedicated 'DVR-CAM' app on your stereo. It has a built-in mic for audio (you can turn it off), and it starts recording automatically when you start your car. Important: This ONLY works with specific ATOTO Android stereos – it's compatible with A5, A6, S8, and P9 series models. It is NOT compatible with F7, P5, P8, X10, or any other brand. Includes a 12-month warranty. A super clean, integrated setup for peace of mind on the road.
