Highest Compatibility For Vehicle Fit/Installation
Currently, the front panel of a 7inch aftermarket car stereo has various sizes (178mmx100mm, 178mmx102mm,180mmx102). However, most mounting dash frame adapter suppliers (Metra, Scosche, PAC, etc.) mainly provides 174mmx98mm dash opening, lots of users encountered issues /hassles during installation. ATOTO S8 universal double din models use size 192mmx97mm, and can fit them perfectly, no trimming/cutting job needed!
This S8 model is a universal double din car stereo, and the extra accessories required to finish installation in a specific vehicle are not included, and it is the buyer's responsibility to prepare for them (if applicable). The accessories that may be involved include (but are not limited to) dash frame kit, wiring harness, radio antenna adapter, data interface,etc.

HD 720P Rearview Video Display with Live Rear-View (LRV) Feature
*Traditional car stereos can only take and display 400-600 lines CVBS rearview video signal. ATOTO S8 Standard works with a specific HD camera (S-AC-HD02LR, sold separately) to show HD 720P rearview video quality.
*Live RearView (LRV) Feature - Access Rearview even if vehicle in moving ahead. This could remove obstructions of passengers, headrests and the vehicle’s roof and rear pillars, increasing field of view (the lanes behind and traditional blind-spots).
*The specified backup camera (S-AC-HD02LR) for Live RearView is sold separately.
Personal Privacy Protection without sacrificing convenience
In order to protect Google /Facebook & other SNS accounts from being accessed, S8 has a screen lock option for users to lock the screen when the car (car stereo) is not in their control (Valet Parking, or vehicle taken by others). An additional option (Unlock with Bluetooth) allows users to unlock S8 screen once phone Bluetooth is connected automatically. You do not have to input the password manually to unlock the screen. Now, all you need to lock or unlock your S8 is just walk out of its Bluetooth range.
