Just after that I've been looking for - but neither the red and blue box shifter nor the "retailers" could offer me a display for my MM-board or even recommended. Only by Google and Amazon, I came across this product. , I have a 3.5 '' inch / 500 MB MM player Grab'n'nGo of Centronics. The display is easy to connect: 1. Yellow cable to the yellow (video) output on the player to connect. 2. Connect the 12V transformer with connector with the red cable or: connect using the cable supplied with the 2 bare ends with a 9-12V other Travo - I did that because I wanted to use an old 9.5V transformer - works well. , When connecting, make sure that not only the voltage is present (possibly measure it), but also a signal from the multimedia player comes - otherwise the screen remains blank! (Logical: It turns the car's only when reversing, if it receives a signal from the camera! , The screen is 4.3 inches and 320 x 240 (not: 1440x272) pixels naturally small and pixelated, but to read the directories, titles, etc., and the equalizer display it reaches all the time - and you no longer need the turn on TV! , A desire on the manufacturer: Especially for multimedia player, it would be useful if a Y-cable is supplied for 12V supply - then the power can be supplied by the transformer of the MM player.
