206 x line 2004 model.... I want to buy tape recorder

Friends, there are cameras and tape products on the Internet between 400 and 500 TL. There is also a tape, that is, a backup camera, which we know, even in his business. There are those who have a double screen, Android multimedia, a huge 9 inches, etc. This is the same price. Which one would you recommend I should get? Do you need to buy a frame or something... I ask the seller if it fits the Peugeot 206 x line 2004 model vehicle, he says it does.. But there is an event, how many pins are 1 and 2 pins or not. I will be glad if you give an opinion..

There are OEM products. This is my advice. But not around 400-500. It starts from 1700. How will the Double go to 206? Also are you sure the android ones are 400-500? So I'll do it too :)
