Moin .. Wanted to get me a rear camera. Have a bit of fun at Luis which offer these in different versions !http://www.luis.de/files/LUIS-Katalog.pdf (page 6 or page 10) Wanted to have one for the truck and one for the trailer. Has an experience with such systems. Would like to solve this quite by radio cameras to save me the cable laying. A reasonable display is also important to me To use this also differently (DVD ,DVB-T ect.) Should around the 350 Euro Costs Greeting
