    1) "why? not saying it's a bad idea, just curious what you are after with it?" -- its a question for non fixed units. I just want to attach it to my fixture and remove it not monkeying with wires. If I can why not?

    2) I'm not picky, I listen to heavy music so clarity is not a big deal to me. What model is your device?

    3) I have been checking most of that out, I'm pretty happy with "car home" the only thing i'd like to see I explained here. http://androidforums.com/android-app...ml#post5887756 I found fusion to work for the most part , it has a neat landscape mode. Still I'd love a radio looking app.

    7) I pretty much gave up on this one and decided to get a stereo I can control with my phone. Still looking in to that. I still may use the OTG for media as I have a dvd/cd/blu-ray player. This is all up in the air at the moment. 32 gig is good but not for there entire music collection. I may look in to a storage linux based box that mounts the dc/dvd to a folder and can be accessed from my OTG usb.

    Thx for all the great info!

    My last carpc was an android based unit, and it had awful sound. I switched to a windows based unit because of 3 key items that can all be solved, but for now it's audiophile quality USB DAC, fast boot time, fast unlimited storage that are the allure of a windows based carpc.

    For android, pretty much the whole concept is perfect for the car, just make it fast to boot (my old unit took 90 seconds till music played), fast to read any size SD card or USB drive ( my old unit sometimes had to be unmounted then remounted, and took 120 seconds to read list of 4GB of mp3s), read +256GB SSD at 500Gb\sec, and windows equivalent USB (USB DAC, GPS, MIC, Phidget I\O, OBDII, etc.) support and i'm back in.

    From what I have read of this past weeks topics, that's what everyone else wants from an Android carpc too, as well as all the great mobile apps.

    rray, have you seen nexus 4? My old android system was really bad but this thing is amazing. Also a bit hard to follow you on the USB DAC but you do know that is possible on android right?

    I had spent some money on decent quality audio gear, but my android head unit, Adayo AN6B01 had terrible hiss, and muddy sound output. I tried to connect an ODAC to the USB on the Adayo, but android had no audio DAC support, so no audio out.

    So I connected the DAC to my GS3, but it burned out my phone. So I looked it up and found out that android had no support for audio DAC's.

    I am waiting for android to natively support the USB DAC, like windows, and linux have done for more than 10 years.

    USB DAC's need no software drivers, are auto-detected as an audio device like a sound card, then intercept digital audio before it's converted to analog by the cheap noisy DAC and preamp typically used in phones and tablets. The low noise floor, and channel separation alone are the reason I use a USB DAC instead of a sound card. It only has stereo audio line out, which feeds my MS-8 processor.

    This is what I have now, and originally I had the Android head unit instead of the PC. I'll go back to Android when my issues have all been addressed, as windows still takes 10 seconds to boot and 30 seconds until music is playing.

    Android Jelly Bean introduced USB audio support, you can use a USB DAC as long as it is a driverless "Generic USB Audio device". the caveat is only certain phones/tablets have the kernel drivers to enable the Android OS feature - so even if you flash a Jelly Bean ROM the feature doesn't work on all Android devices. oh well, at least it's a step in the right direction. i can't wait till Android get's multi-tasking (yes there are custom ROMs that support it already, but i mean native support). the new Windows tablets can do multi-app split-screen, but they are still new and pricey (for the Pro versions) and don't have a ton of apps available yet. Everyone seems sure the next version of Android will have multi-user support, so it is growing features. i personally didn't think it was a feasible platform for a carputer till Ice Cream Sandwich.

    i don't know anything about the Adayo devices, but most people never turn off a typical Android tablet based custom carputer - you just have it go into airplane mode when the car turns off and it can run on it's on battery for a week or more... so no boot time issue.

    there are pros/cons to any OS or hardware you choose for a carputer... the average consumer would say "why even bother? my Alpine/Kenwoon/Pioneer stereo does everything i need." - but this whole community is about doing custom things and everyone has their own unique approach and reasons for going the way they did.

    I hear the nexus requires a root, mine already is so does not faze me any. The battery with nexus is phenomenal, so yeah no need to reboot it.

    The Adayo comes with Froyo (Android 2.2)
    -- that is the OS I first had and I will tell you a nexus 4 (os ver 4.x) is a dream compared to that crap. 4 times the battery, 4 times the speed, and much more stable.

    Hi, your thread motivated me to sign up. I've got an android install in my car that is working pretty well for me. I've already tackled many of the issues you and others have mentioned here after a bunch of research, trial and error. I created a new thread since there was a lot of info I wanted to cover and I didn't want it to get lost in a reply.
