This is a great combo device to upgrade your older vehicle.
It gives you android auto/ apple car play functionality, gives you bluetooth for music (some older cars have bluetooth for call only) via the FM transmitter, or via aux directly to your vehicle speakers, or you can just use the built in speakers on the screen... prob not the best option but its there. The screen is good quality too, pretty bright which is good for in vehicle screens when they are hit with sun.
There is a camera on the back side to act like a cash cam, and rear view cam can be set up, and you can even adjust lines for guidance... I didn't set up the rear view though since my vehicle has it.
The front cam quality is good to see what's happening, but you wont read license plates with it.
My only complaint is the mounting mechanism. The only option is tape, which is fine (although the option to suction it if you have the room for it would be awesome. The tape is quite strong, but since its on the dash board, it will be on a non-smooth or flat surface, so it's not going to be a perfect fit basically anywhere in my vehicle, and I bet most others would be the same... I'm not sure how to remedy this, but I would have liked to try and suction it to the windshield somewhere where my view isn't obstructed.
