Sorry , Here it is :

By this I'm a little confused. My understanding is that the Galaxy Tab is a Multimedia tab that passes through with an HDMI Port, but also has a 30 pin port to it for the Samsung 30 pin connector to usb cable. I'm not sure why that would make any difference as far as if it would be on or off. But I just don't understand that stuff.
I'll check out the forums, but the problem is, I don't know what i'm looking for to say what's better or worse or whatnot. That's why I was posting on here.
Who is xda-developers btw? Is that on here or somewhere else?
Each device has its own abilities , and acts differently according to what the manufacturer designed and the developers community achieved..
XDA-Developers , Is where 99% of current phone/tablet hacking starts
Here is a quick link to the galaxy forums : http://forum.xda-developers.com/forumdisplay.php?f=752
I suggest that if you are planning to install a tablet in your car that you would know how to handle it..
First according to specs , there is a 3.5mm connector ( Anyway , I haven't seen a device out there without so check again.. )
The reason I'm going through all this is to get an analog signal, preferably a strong one, and then you talked about the optical signal. I only have, with the Galaxy 10.1, an HDMI output via that multimedia tab, or a usb output to work with. There's no other outputs on it. They aren't making an adapter yet to do a whole lot, like Apple is right now. If I could get a composite adapter that has composite RCA,s and a 30 pin connector, I'd be happy about that even though I'd still have to find a way to charge it all. But they don't make one yet.
Yes you need an analog signal to set up the Bit One, but once it's set up you can use the optical input if you want or the analog input. But you have to have the analog input to "set up" the Bit One. Don't have to have it every time you turn it one, just when you do your original set up.
There isn't a usb output on this tablet. it's a 30 pin connector for Samsung, and the multimedia tab plugs into it with that 30 pin connector. The multimedia tab itself has an HDMI port out, and another 30pin connector (same as it plugs into) for the charger or whatever. So I'm not sure about the USB-HOST stuff and how or what to check out. There isn't a 3.5mm jack on it, that I can recall. Actually there is one on the dock, but I'm not gonna use that anyway.
A simple 3.5mm to 2 rca cable will do the work for analog , As you said , You just need it once..
The USB-HOST ( OTG = On The Go ) stuff probably connects to the 30-pin connector with a special cable ( I'm sure the info is on XDA )
When you are on XDA search for the devices that known to work , devices that don't , etc..
If the developers enabled USB AUDIO then you can get audio from the device using the stuff we mentioned earlier ( USB DAC for analog / USB to SPDIF for digital )
This and the headphone out , Should cover the audio part of your install
Talking about overkill's :)
I Think it would be best to invest in a good solid 5v power supply than in a hub..
Unless you are planning a din install of course..
The Nook can charge and act like a usb-host , Simultaneously
This looks promising! I like that. So how do you have that hooked up? Do you power several items via usb? I would be very interested to see how this hooks up.
I already successfully hooked 4-5 devices at the same time and that worked great
I plugged 3 mouses and even moved them together ( it was funny to see 3 cursors jump around :) )
My USB-DAC , flash drive , card reader all worked as expected too
According to usb port specs - It should connect 127 Devices per port as long as power is not the issue , so no worries there..
Also , Only the hub needs to be powered through it's own power connector - All of the devices ( Including the nook ) get the current needed from there
Here Is a video of a guy with a Nexus One ( The first Android phone to get usb-host support if I'm not mistaken ) , Using A-LOT! of devices at the same time
Everything that support linux can be hooked up eventually - The question is if the driver has been ported to Android.
I get your basic needs and I think we covered the audio part
So my basic needs are this. I need an analog audio signal from the Galaxy 10.1 Tablet to the Bit One, preferably a good one. I need a video signal from the Galaxy 10.1 to the headrest monitors. I need to power the Galaxy 10.1 while it's in the dock in the car. That's about it. Nothing more nothing less. Would i like optical, of course who wouldn't. Do I need it, no I don't. So until I can figure out how to get it, then I'm not going to worry about it, cause it's not that great a deal to me. Yes it will sound 100xs better, I get that. But if I don't have it, I'm not gonna cry over it.
Those are my basic needs. Now I'm probably not gonna get back to this for a few days, I'm going camping and since the mods have to approve all my posts, this will probably not post till this afternoon and I'll most likely be gone.
I wish I knew more about this part of the electronic world, but I just don't. That's why I'm trying to get help. I don't mind researching but sometimes doing that in this part of electronics, can just absolutely burn my head till my brain explodes and then in the end, I get nothing out of it. Most of the time. I'm not dumb, at least I don't think so but you can reserve judgement till a later point if you want to, I just am not familiar with these types of parts.
Thanks for your time thus far, hopefully we can figure out the best way to make this happen then I can build it and we can all share in the joy of it! Thanks!
As for video , you need to check if usb-host can work with the HDMI out and that no-one cancel's another
Once you do that you have 2 options from my point of view :
1.usb vga ( if supported ) + vga to composite converter box ( available at low prices online/ebay )
2.hdmi to composite with whatever converters you decide to get..
I don't see any other way to get composite out of the device..
Have fun in your vacation , And your welcome :)
