I just picked up a 2003 LX 470.it has the factory GPS DVD head unit but it also has a flip down screen for the rear passengers. It definitely looks factory. I can't seem to get the DVD to show up on the rear monitor. I can get it to play on the front monitor but not on the rear. it just keeps reading "no disc". any thoughts to my problem? I have the factory remote with new batteries and pushed the DVD button and it switches to DVD but just reads "no disc". I thought maybe there was another slot for the rear DVD player to insert another DVD, but I have not found anything. This vehicle is a little fancy for me. I have been in a built LX 450 for the last few years and it is nothing like this LX 470 that I now own. I love this vehicle but it is a completely different type of vehicle altogether. I am used to asking questions about building axles or bumpers not technical DVD questions. Is almost awkward to ask or even start this thread.
