I have an 2003 X5 with Nav, CD Changer and DSP. I recently installed the TVonNav module and have tested the Video In on this with a portable DVD player and the picture works. I have purchased an incar DVD player that I want to mount under the passenger seat, the Video output I can plug into the TVonNav Video In but I don't know where I can route the power from. Where is the best place to get it from? I was thinking about the DVD plug used by the BMW Entertainment system under the CD Changer but am unsure which cables to splice into. Any suggestions?
