Home dock for car use?

Saw a nice video on YouTube about a guy who mounted his Streak on his Harley using the home dock, and figured at the least, the dock would make a good starting point for a car installation. All other mounting options require that you not only plug in the power connector at the bottom of the Streak, but also a cable into the headphone jack to get audio out, and, in my understanding at least, with the dock you can just plug the Streak into it, and it should turn off the Streak's speakers and direct the output to the dock's audio-out connector(s). Since the dock has disappeared from Dell's website (at least in the US, still listed in the UK), can someone who has one tell me what type of audio out connectors it has? Don't suppose there's any way of getting a back-up camera to display on the Streak, eh?

Also, what sort of power connector does the home dock have? Something I can adapt to be powered by the car?

The 30 pin dock connector supports:

USB out
USB charging in (2.0A)
USB dock sense
HDMI out
Line out

It reroutes though hdmi/lineout by sensing what's plugged in.
Lineout is sensed by being docked, hdmi is sensed by being connected.

The dock has no active chips, it's merely traces that run from port to port.

The audio out is 3.5mm stereo. Get a 3.5mm to RCA stereo cable.
The power cable comes with the dock. It's a standard USB connector on one end, and a prorietary connection on the back of the dock.
You can connect power off of a 12v car adapter that you can plug a standard cable into. I got the adapter from RadioShack. They make a nice 2 Amp USB cigarette lighter adapter. Get the 2 Amp.

I've been running a home dock in my car for at least 6 months. It works like a champ. I used a piece of flat aluminum bent into an L to hold the dock and place pressure on the bottom portion of the tablet to create enough resistance so the tablet doesn't fly out. I used rubber feet I got from RadioShack placed on the L bracket so as not to scratch the tablet and provide the needed resistance.

Mounting the dock will vary from car to car. Getting the dock mounted and stable is the hardest part. Again you need to have enough resistance on the tablet when docked so that it doesn't go airborne when you take a hard corner or launch your car off the line.

I drive my car like I stole it, on a daily basis. I haven't had the tablet come out of the mount yet.

No way to wire in a back up camera. You'd have to bring the video in wireless somehow. It would be cool, but more trouble than it's worth IMHO. If you go for a back up cam and get it working well let us know.

Cool, just found one for $50 and $2 shipping. I've got a good bit of dash real estate on my Mountaineer, where a Kenwood 7" double-DIN touchscreen/nav is now installed. Figure there's room for the dock and a standard DIN HU behind where the tablet will sit.

Will it run dual-screen with the dock? I'd like to convert the HDMI out to run video to the rear monitor. I'm cool with it displaying the same video onscreen as the external monitor.

The hdmi out mirrors what's on the screen, but on the s7 it only outputs at 720p and not 1080p like other t2 tabs. I dont believe you can set it to anything but mirror.

Thinking about the camera, was wondering if some sort of wireless TCP/IP camera might work. I know there are apps to view them on android, the trick would be getting it networked to either the streak or my cell phone (which the streak will be wirelessly tethered to).

As I understand it the dock also has a mini USB host port. An OTG cable to a USB camera might work.

Finally got around to installing the dock in my Mountaineer. Just for a "proof of concept" trial I put in an old Kenwood single-DIN HU that I had lying around. Used 3M heavy duty "Velcro" on both the bottom of the dock and in the slot in the dash adapter (this one is from Metra, Scosche also makes one, but I don't know how well that will work).

Streak is tethered to my cell, so I get internet access for nav, tune-in radio pro, Iheart radio, Google Music, Netflix, etc. Unit is powered by the OEM T-Mobile car adapter. No video out yet (and I was wondering if the line out audio cuts out if the HDMI is used or not). I've got the USB cable hooked up and running to the glove box for access, but I've got no use for it as yet.

Simple, easy hookup, but it looks pretty decent when the tablet is hooked up, and despite washboard roads and high speed sharp turns, it stays put and working. Now I just wish there was an app that would allow me to use the tablet as a bluetooth adapter for my phone, so I can place and answer calls...
