Hi, I have the AVH-P4000DVD and a rear seat 8.5" screen. When I select 'AV', it displays my RCA input on the rear screen, but I cannot figure out how to get it to display on both at the same time? Any ideas?

Hi everyone, I just got a Pioneer AVH-P4000DVD installed in my Explorer at Crutchfield, it works great, but I've noticed that after about a week the iPod will die and I'll have to recharge it manually. The installer tried to tell me that this unit doesn't charge ipods, just plays them. For some reason I dont think this is the case? Is there a reason this might not be charging my iPod, and is there anything I can do? Thanks
