Just wondering if anyone has tried this Isimple IS76 audio-video/charging cable with a Z series HU?.. It has to be connected to a 12V power source in order to charge the 5V Ipod/Iphone version devices, but that should be simple enough. I'm going to try connecting it to the A/V Input RCA's in hopes of keeping the phone charged while getting audio and video from my Iphone4 to the head unit. I'll post an update when I get it installed.
