Hey guys, I don't really come around here much anymore, but I thought since this project is an Android project too, I'd post it here.
FIRST: I don't want to hear about how this is a stupid idea or anything like that.
Anyway, here's what's going on:
I will be installing a Nexus 7 in my dash, completely automated, integrated, and removable. When it is slid into the dash, it will automatically turn on Wifi, Bluetooth, and Music, thanks to NFC tags. The N7 will stream audio to a Bluetooth receiver, which then feeds into an EQ. From the EQ, it goes to my sub and 4 channel amps. The N7 will be kept charged by a hard-wired POGO pin charger.
I'm debating whether or not to make a pod for my GNex (also removable) that will use NFC to automatically turn on Wifi Tether.
Update 12/5
My prototype POGO pin charger works! Although currently looking like a death trap, I will clean it up and hard wire it into the car when it completely ready. (Testing was done with my GNex. I know the pins are in different positions, this was just very early stages of development, for testing purposes.)
Update 12/7
The Nexus 7 will be bought on 12/9. NFC tags and RCA level controllers were ordered and should be here in a week or two.
Update 12/9
Picked up the Nexus, and began cutting my dash to fit it. More cuts will be made, and then fiberglass will come.

Dude! I thought about this myself and said..that's a stupid idea. Lol
What I mean is Wow! That is cool. I was driving today thru Philly with Nav and was thinking I need just that.
Very cool. Keep us posted.

You have never idea how bad I want a dash mount in my jeep wrangler for my N7.

I was thinking something on the steering wheel. So you can just look with peripheral vision. I guess not to good having it smash you in the face at 3 gs when the airbag comes out. Clips of some type. Nothing as elaborate as this. I would pay for this in a heartbeat. You could build these into homes, cars, a water proof one for watercrafts and boats. Etc. I want in on the the aqua patent rights now. Lol

A couple months back i was reading about someone doing this. I thought it was this forum. Maybe not. The project was fairly far along, but I never saw completion. Looks great so far!

There was a topic posted here a few months back:

You might want to refuse the 4.2 updates so that blue tooth will work. The 2 middle pogo pins with ground are audio out. I think there are custom roms that will allow charging while using usb, if you can find a usb soundcard. I wonder if the netzero portable 4g hotspot would work?
I've been tracking pogo stuff on xda, I want to make a small dock that will attach to a wall instead of on a table. If used as an alarm clock, I'm pretty sure it will go flying if not nailed down.
I've seen sources for the pins, someone should make a 4 pin subassembly with wires preattached. Because I'm lazy.
Good luck!

From what I understand, the BT issues were fixed with 4.2.1. I sure hope they were, because I already updated...
A for the hotspot, anything that creates as infrastructure network will work. My phone does it, so I will be using that.
-
Bluetooth was not fixed with with 4.2.1. There was a Bluetooth driver added for gamepad support. The Bluetooth audio has not been addressed. The install that I read about before was over on droidrzr.com. He used hardwired connections, not the pogo pins.

Very interesting. I'm in a few IRC channels and there are a lot of us Android geeks. A fee of them have N7s running 4.2.1 and claim to have no issues streaming audio via Bluetooth.
I guess I'll see how it goes when I get to the part of the project. For now I'll focus on the fiberglass dash.

Barry can give more insight into this, but the issue arises when streaming Bluetooth while using Wi-Fi simultaneously.

It is crazy because some people have no issues. There are however hundreds of folks i see posting in Android developement threads that have the same exact issues.I have had the issue with the BT audio since I bought my first Nexus in late July. It arises when you have WiFi running along with audio output to a BT device. The sound stutters, Youtube video, will stutter and their is also a definite delay in sound to the speaker. I know you don't need WiFi to play native files but for troubleshooting purposes if WiFi is on, BS, MX, PowerAmp etc all stutter. As soon as WiFi is disabled. Perfecto. The opposite is also true. If you are playing video/ audio thru wifi and BT and it is choppy then turn off BT, it runs fine immediately thru the Nexus speakers.
Note. I have had this issue thru all of the updates since July and on two different machines. 5 different speaker companies and 7 different speakers.

Loocid .Did you open your Jam yet? I discovered the issue using that very speaker. I spent days with my new sling box and speaker pissed thinking it was my sling box causing the video stutter. It was the damn BT/WIFI combo.

No I haven't opened it yet. Was in no hurry until the issue gets sorted.

Do you definitely have the problem? Pardon me for not remembering , have you tried any other BT speaker? You could be one of the lucky ones. How about on the little computer? Can it be tested on there as well?

I'll definitely do my diligence in testing with my mini, and my wife's Nexus as well. I've never tested the issue on any of the devices. I was waiting on the Jam for Christmas as well. I'm actually surprised that I held out this long.

Just went out and tested my Bluetooth audio while connected to my current radio via BT, simultaneously with my home wifi. I had no issues, and tested Netflix, YouTube, Spotify, as well as local music/video files. I had no stuttering or anything. Hopefully this is still true when I get the new Bluetooth receiver I will be using, since this is not the one I will be using when I get to that point of the build. Thanks for your help and concerns, but it looks like I will be fine for now. :)

Some tape to hold it in place, to give you an idea of what it will look like when it's done.
Hopefully buying the fiberglass resin this week to get started on the actual build.

Oh, no one here saw my "prototype" pogo charger, but here it is, all cleaned up.

I am waiting on some probes to go on the end to complete the pins.
-
No latency either? While watching video? I never used a BT radio. I am not sure of what the difference would be from just a bluetooth speaker like a Bose or Jambox but I am glad it works for you.

Alright Barry, I broke down and tested the Jam. Worked great. Streamed music from Google play anger played at full volume with no issues whatsoever. YouTube videos have no sync issues or buffer lag. Guess I'm one of the lucky ones?

Do you think I am making it up? I give up.
So what could it be ? There are a lot of people with the same problem that I have . I am beyond frustrated and starting to get pissed.

Just to show I am not crazy. And yes..You are one of the lucky ones.

Maybe all the devices that work should have a 'compatible with Nexus 7/Bluedroid' sticker.
-
So, I stopped at Advance on the way home to pick up fiberglassing stuff, and the cashier asked "What are you working on?" So I told him I was putting a tablet in my dash. He answered with a confused look and "Like uhh... internet tablet?"
Anyway, I have my fiberglass resin and whatnot. Waiting for it to either warm up, or me to find a warm ventilated area to proceed.
Looks like my NFC tags will be here tomorrow, my POGO probes will be here at the end of this week, and my RCA level controllers some time this week as well.

Lol I know your not making it up bj!
And if its Bluetooth it should be compatible. Its usually not a problem with whatever the device is but with android. In my experience no matter what brand it seems like half work and half don't whether its a Samsung tablet or phone or an Asus or a Sony or whatever.
Good work inm I can't wait to see the finished product! Did you mention what car this is going into yet?

Just so everyone knows, no, I haven't given up on this project lol. I'm just extremely busy with work, and it's a bit too cold to be fiber glassing at the moment.

It's not the prettiest thing, but it will all be covered up.
I will be covering the card slot thing and putting 2 knobs there. One for volume, and one for subwoofer controller. Once I get that done, I plan to add a thin felt of some sort to the place for the nexus to sit in.
I still need to figure out how I will make sure the Nexus doesn't move while its in there. I'm not 100% sure if I'm going to be doing the POGO charging at the moment. I'm getting a little tired of this project already, and just want to be done with it... lol.
Next step is some body filler. Hope to get that done in the next couple of days.

There are folks doing dash mounts that use a kernal made to allow charging while OTG adapter is connected all thru the microUSB connector....no need for pogo at all.
