The Dometic PerfectView M 55LX gives you all the benefits of Dometic's advanced digital monitor generation. Its bright, high-contrast 5" display is easy to read in all light conditions, even in low temperatures. The automatic trailer recognition comes in very handy when you travel with a trailer in tow. Then there's the three additional features which offer drivers extra confidence during manoeuveres. Firstly, it has four camera inputs rather than the standard three. It features helpful distance marks to define the borders of a danger zone while reversing. And, thirdly, it comes with an attachable sun shield to guarantee a glare-free view. A superb and reliable accessory for safe driving.
