[QUOTE="Lexicon740iL, post: 8122219, member: 649368"] 1. You need to feed that USB plug that goes into your tablet 5V not 12V 2. Use a cigarette lighter to USB plug adapter like mentioned previously to knock you 12V feed down to 5V for your USB cable into the tablet. 3. If you want to hide everything just use a female 12V cigarette lighter adapter that terminates into bare wires or get one with a trailer plug or something and cut the end off and wire it into the 12V Switched and Ground of the harness for your stereo. Like this Hook one of these into your 12V switched and Ground on the stereo harness [IMG]http://thumbs1.ebaystatic.com/d/l225/m/md4bUGbNd6qZveBENXKNdUg.jpg[/IMG] Then hide it behind the dash and plug one of these into it [IMG]http://i15.photobucket.com/albums/a391/RollaMo-LT4/HD%20Forum/USBtoCigaretteLighter.jpg[/IMG] Now plug your tablet usb cable into the USB adapter and heat shrink the connection. Voila 12V to 5V USB rail hidden behind dash and the lead is only charging or hot in key position 2. But keep in mind just because the car is off it wont turn your tablet off it just wont charge. You will still have to power down you device manually for a full off or just let it go to sleep. Hope this helps. I have hooked up tons of A/V retrofits into OEM screens/Navi head units in my BMW's this way. [/QUOTE]
