I'm picking up my c3 early next week and have already been browsing the forums and checking up on mods to make. I think I'll be keeping the stock touch screen unit for now but would love to have a video input for a game console or media center. I found the Beat Sonic AVC39 cable ( the forum won't let me post the link to it yet) It seems to do the job I'm looking for but as far as I can tell it's just a go between from the regular cable to the back of the unit with the composite plugs spliced in. Rather than pay 80-90 dollars for the lazy way can anyone post up a detailed wiring diagram or some decent close in photos of theirs? If there are options other than that cable I'd love to hear about it as well.
I'm looking to the Internet about the cable you mentioned and stop by this forum from beat sonic, the moderator mirrored the phone to the HU radio on the Prius C. Add Video Input and Smart Phone Mirror to OEM Screen on 2012-2013 Prius
