    Apple TV 2 Power

    Im super new to this. I want to install an ATV2 in my Excursion and feed the video to my OEM screen. The ATV2 has an internal power supply that takes 110 AC to 3.4 DC at 1.75 amps. I want to remove that and run just DC to it.

    I am having a hell of a time finding a converter to take my 12v to 3.4. I did find on ebay a 12v to 3.3 volt 3amp 15 watt converter. They are all from china. Are they any good? Is there a domestic supplier of such things?

    Any help or direction appreciated...

    current-logic is a good supplier-- i have seen a couple of projects that use their voltage converters.

    with that amount of amperage, i think that is about as close as you can get.

    you could try something like this(some variable voltage converters), but they are not as cheap as that first option:

    Thanks for your help!!!

    This where Im at now after your comment on the step down converter. I am going to abandon the head stereo unit as it is shot. I have 6 CDs stuck in there. Also going to abandon the rear dvd cuz Im sick and tired of scratched dvd's and it won't play copied dvds. Will replace with a double din unit.

    So I plan on using the stock LCD flip down screen with an Apple TV 2 and an aftermarket head unit. I will install a router to stream movies from an IOS device (iPhone, iPod or iPad) to the factory screen. Here is my plan.

    Will remove dvd player and close the opening up with ABS Textured plastic and will paint to match with the ford interior paint from Diesel Manor. ABS Textured Plastic Sheet 1/16" Thick x 12" x 24" 265-940

    Will mount Apple TV in the cabinet where factory DVD once was. I will use the 12 wire OEM wiring that went from OEM head unit to OEM DVD player to take audio from apple TV to the head unit so thats 4 wires.

    Now the ATV2 will need power so one wire from the OEM wiring will carry power but stepped down to 3.4 volts so I will use a step down unit. 12V to 3.3V, Step-down, 3A, 10W : Current Logic, Expert of DC-DC Converter

    Apple TV2 has HDMI out only so I need a device to take the video and audio to composite. For only $42.00 each when QTY 50+ purchased - HDMI to Composite Video Converter | HDMI to Composite Converter

    This converter device is 5V so another step down unit is needed to use this so another wire from the OEM wiring I will use. 12V / 24V to 5V, Step-down, 3A, 15W : Current Logic, Expert of DC-DC Converter

    This router OM1P 802.11g Mid Power Mini Router - Single Band Series runs on 12 volts and will be put in the bottom/back of the center console where the rear plug in audio jacks are. I will run a new power wire for it. Also going to remove the rear audio plug in and use some of that ABS plastic to cover where the it went and put two more 12 volt outlets or perhaps an inverter in there with an AC outlet one day.

    So all of this is the easiest part. Whats going to be the tricky part is figuring out the wiring that goes to the OEM LCD screen. From this thread I see that video goes to the LCD screen on one of the 3 yellow wires. I am hoping it will be as simple as simple as grabbing one of them and trying it out till I get one to work. Trying to find the power wire to the LCD screen is also going to tricky since i have never taken this whole thing apart before.

    Wish me luck....

    sounds like a plan!

    for the audio, you might want to consider running some fresh rca cables. i don't know what the factory wiring looks like, but in most cases, it is not designed to carry a audio signal-- only power, so the audio might not be very good quality.

    Actually the factory wires are for audio. It takes the audio from the DVD player output to the factory head unit. Also here is the thread I mentioned but forgot to post showing some of the wiring I'm trying to figure out to the OEM lcd screen.

    Well it seems powering the OEM screen without the OEM DVD player is going to be a *****. The power and all that comes from the DVD player. Had a stereo guy look at it and shake his head. He said he could try but could not guarantee the thing would work at all when done.

    I really don't want screens in my headrests and the OEM screen is nice for the 3rd row folks.

    Next idea which is way easier....

    After market front head unit and power up OEM DVD player. This is easily done and numerous folks have done it. I will have an iPod Classic that is upgraded to 240 GB.

    The DVD player has AUX connections so iPod can be hooked up right at the DVD player. Apple makes a 5 foot cable that has a USB charging cable and composite output so the kids or mom could browse the iPod classic from the second row while it was still plugged in for a video to watch by name or movie cover select it, pay it and set it down.

    In the future I would like to tap into the aux ports at the player like in the thread I linked on here had done and wire it down to the center console. Only want to do this to clean things up with wire hanging etc. It would also be cool to tap into the out video feed like was done on here so iPod could play over back screen and aftermarket head unit up front.

    Any update? I'm really interested in lessons learned during the DC mod to the Apple TV ... thinking about a similar mod.

    dude,
    i like what you have done, I am about a year behind you. I want to install the atv3 in my motorhome.
    I have stripped my ATV3 and pinned out the PSU. I have managed to power it up using a 12v supply regulated down to 3.4v, prob more my luck than judgement. What pins did you use to power the ATV? and how did you connect them. I have been looking for an 8 pin connector to match the PSU but I dont think it exists. It is probably unique to apple. So im wondering how you connected you supply to the ATV.


    kind regards
    G.
