    that will still only be composite low res output. If you want to try it without hacking or adapters, plug your composite screen into the green component connector on the ATV for a monochrome picture, and see how readable it is.

    I just got one of those cheap component to VGA adapters made for video games. I'll let you all know how well it works.

    OK, I tried my cheapo component-vga converter on three different LCD displays and only got it to work well on one of them. I still have to drag this out to the car to try it on my dash display, but I'm not encouraged by my findings. I was only able to get it to display at 480p, but it may be a function of this converter, which is made for video games, not computers. I only paid about $30 for it, so it wouldn't surprise me if a better converter and/or better display did a better job with this.

    So, has anyone thought of using the new official "remote" app from Apple (NOT "RemoteBuddy") for an iPhone to control an AppleTV? This looks like an interesting way of doing it.

    AppleTV's audio into your car stereo, and you use "Remote" on the iPhone to control iTunes, just like you would control an iPod touch manually. Then you can also use your GPS on the iPhone, etc.

    Also, for those of you w/ AppleTVs already working in car, how are you dealing with heat and ventilation issues? I've heard that they run very hot.

    AppleTV in my car

    It would be functional to be able to control the Apple TV from the iPhone or iPod Touch however for me I don't want to have to remember another device when I get in my car. It would be useful in the sense that I could run a dual system. Kids can watch movies from AppleTV on the big screen in the back seats (headphones on) while I listen to music from the iphone in the front. But the kids are controlling the AppleTV with the remote anyway. With the remote I can also control and see the AppleTV on the screen in the front in my dash. So really not required in my situation. Others may differ.

    My AppleTV has not had a problem with heat. However, it is suspended behind the center console where the ash tray used to be and has quite a bit of air flow around it. I would not jam it in a small enclosed space.

    The single biggest problem with AppleTV in the car in my experience so far is that it keeps losing the entire iTunes library and has to re-sync everything which takes weeks. The reason it loses the library is that there is no graceful way of shutting it down automatically (without the remote). I have a smart automotive power supply from Opus that keeps the ATV up for up to 1 hour after I shut the car off (depending on battery voltage). But I gather if the ATV shuts down after an hour in the middle of writing to the hard drive it can corrupt the file and needs to re-sync. Movies take a long time and they sync first. Sync only happens in my driveway for an hour at a time. So I live without music for a while!

    If anybody can help figure out how to automatically shut/sleep AppleTV with hardware then it is viable for the car.

    I hadn't heard this. Is there a button on the ATV that you push (like the power button) that will sleep it or shut it down like the Mini?

    I *think* (I don't currently have an ApleTV) that there is a button on top of the case, and also possibly a way to do it via the remote, that you can hold down for a few seconds and it puts it to sleep.

    I would imagine then, that if yours is hacked you could ssh in and write some sort of shell script that would accomplish the same thing (so you don't have to have physical access)? Not sure...

    No button on ATV. Have to use remote by holding play/pause for a few seconds.

    My other post went missing but I wanted to say that I have AppleTV in my car and the biggest problem is it keeps needing to re-sync all content because a file is getting corrupted when it powers off in the middle of writing to disk. This is really a problem because it takes the ATV weeks to upload all content again. I have a smart power supply from Opus that powers off the ATV after 1 hour or if the battery voltage drops too low. There is no way to automatically shut down the AppleTV gracefully. The only way to sleep it is via holding play/pause on the remote for a few seconds.

    The AppleTV will only be viable in the car if someone can resolve the power down/sleep issue. If someone can help with this it would be great.

    Is there a way to either partition the AppleTV drive, or maybe just put the OS on a USB stick, and make it non writable? So you would use a special partition on the appleTV for storing your media files and your swap file (or simply create yet another partition for that if it is not already done) so that if you power it off, it always reboots from the USB stick w/ an image of the regular HDD in the same state every time (and therefore you don't run the risk of messing up your drive image)?

    Perhaps a "Patchstick" USB that has the AppleTV OS on it rather than OSX (Tiger), and then chmod the stick to read & execute only. I would think it would have to mount the other partitions (the writable ones) on bootup, so that mount point would have to have write perms, but other than that I would *think* that that would work. Now I just have to google and see if someone has done this already. :-)

    Now that I think about it, you'd also have to force iTunes to store EVERYTHING in the readable partition otherwise you could never add new files or playlists (unless ssh'ing in, chmodding itunes, creating your playlists & adding songs to the DB & then re-chmodding to R-X isn't too much of a pain), right? For me that's no big deal. I don't change that stuff too often, but for others it might be.

    Thanks for the suggestion. I think the AppleTV already works that way for the OS. It is the media content/library file that gets corrupted?? In any event it has to get updated regularly as I am adding songs/movies/podcasts all the time so must always be changing. Its got to be maintenance free for me.
