[Nexus 7 General] regalpimpin:
I'm going to be leaving my stock radio intact, and using a ProClip mount. That way it will still look good and I'll still have a radio, and cd player.

Actually, the proclip for my car installs in a matter of seconds and disappears just as fast, so it will still retain the stock look.

I've already run an ipod2car to my changer inputs, then converted that so I can use it as an ipod cable, or an aux in. Then I plug in an htc stereoclip into the aux in for bluetooth. So it will be wireless to the factory deck. All of that stuff is hidden in the dash so all I have exposed is the little aux input and the bluetooth receiver.

I have to do it this way because my radio is in a piece that goes all the way across the dash, and isn't in a modular center console piece that I can pop out and work with. So If I put it "in" the dash.. it would be permanent and I'd have to do all the amps.

I'll post pictures once they make the mount for the nexus and I get it in. For now it just rides in the passenger seat.

The gauges are from an app called Torque, and it uses a bluetooth OBD2 reader that can be found on amazon. It's good for getting some basic numbers, and even allows logging. But there is a slight delay and well, it isn't much compared to my HP Tuners for my car but that's not saying much. it is definitely a must have for any car installations.

Idk I might not end up doing it I think my timing belt is more important along with getting my exhaust fixed....

Plus its an Asus Tablet and I had bad experiences with them with the prime....

Plus me being 17 and just getting my lisence idk if I should be distracted while driving
[Nexus 7 General] swan3609:
I am interested in this as well.. I just put a cheap double din DVD player in my 01 forester and I would totally send it back and use that $200 to buy a nexus 7.. I just want to figure out how I could mount it and still be able to remove it with out taking the dash apart.. The other thing is what is the best way to get your audio to your speakers if you dont have a amp installed? I guess I could just get a small cheap amp if I needed to.
[Nexus 7 General] RED ZMAN:
I'm running a Samsung galaxy tab in the dashboard of my Kia soul, 2010 sport model, for over a year now.

A lot of whine and stuff to the stereo, but then I got a 3.5 mm cable with a ground loop isolator on it. Did you get one of those? It solved my problems.

A couple members on my website, soulhamsters.com, are also using Nexus seven and other tablets in their dashboards.

Blasted from my HTC Rezound (Zone23s Newtified 3.2.1)
[Nexus 7 General] timskyline86:
This is because you don't have it grounded properly. Either your sound system, the nexus or could also be from the charger.

My guess is you messed up the grounding on the device itself, if you look at the backcover IIRC there is a spot for that. What did you cut with your dremel?
[Nexus 7 General] curseddagger:
Amps are grounded using 4G cable straight to a very clean ground point on the chassis (scrubbed with wirebrush and sandpaper), the nexus when running on battery AND when running on the charger still buzzes but the ground for that is through the charger and once again, straight to the chassis. Ground loop isolators havn't helped, i have tried them in every combination possible.

I simply ground off a piece of plastic on the inside of my dash to make it fit with the dremel, havn't modified the device at all.

Thanks for your suggestions
[Nexus 7 General] stezo2k:
This is amazing :D
[Nexus 7 General] RED ZMAN:
But did you try a 3.5mm Audio cable WITH a isolator?

Here's the one I got that fixed my issues.

http://www.amazon.com/Kensington-Re...qid=1344387678&sr=8-2&keywords=3.5mm+kingston

Fixed my issues completely.
[Nexus 7 General] curseddagger:
pretty much exactly what i used. as well as inline RCA ones on the amps
[Nexus 7 General] timskyline86:
Have you tried plugging the N7 into another stereo/amp? Just to see if it is the device or your system.
[Nexus 7 General] curseddagger:
Theres 2 issues.

1. The system is noisy without anything plugged in and

2. The nexus is also noisy and it adds to it.

The nexus plugged into my hifi setup at home (or even really good headphones) still is noisy
[Nexus 7 General] timskyline86:
and you tried different audio cables? thats the only other thing I can think of for the nexus.

For the system something isn't grounding right, you said you have a ground loop iso correct?

If so one of your wires are probably messed up after the iso.

Other way to find out is to test, if it's preamp or post amp, is to turn on the amp without an input. If you hear no sound until you plug it back then you no which direction to go.

Hope this helps if you haven't done that already, I know it was a pain trying to figure in my car and it was all because of one wire.
[Nexus 7 General] curseddagger:
Thanks heaps for your advice, i appreciate the assistance! it's doing my head in...

I have replaced all the RCA leads to test it.. it still whines when i use a brand new cable directly plugged into the side of the amp in the boot. I'll have another poke around when i get home.

p.s. it seems to only be when i link the amps together either through rca splitters or by using the summed output on my sub amp.
[Nexus 7 General] rman726:
Looks pretty sweet. I've been tempted to do this to my car, but I've been hesitant to remove my stock stereo as it really does fit in well with the rest of the car, including the in-dash display. Think I'm just gonna wait for Mountek to release a tablet version of their CD slot mount.
[Nexus 7 General] krazichinaman:
That's an awesome build. I currently have my galaxy nexus mounted to my dash and Run torque and a bluetooth OBD2 Dongle. Nothing like having a digital boost gauge and A/F gauge!

I personally think the N7 is too big to mount in my 2011 wrx, but to each their own. None the less your build is clean!
[Nexus 7 General] e.mote:
@OP

Have you tried viewing it with polarized sunglasses? N7 is horizontally polarized in landscape, so would be a problem for (vertically polarized) sunglasses. But you would be looking at it at an oblique angle, so maybe not. Those in the backseat would be more affected.

I don't think consumer tabs are suitable in permanent car installs. Temperature variation (especially if you live in extreme climes) will damage battery longevity, and many of the plastic components will likely warp or even melt at sustained elevated temp. As the screen-lift issue illustrates, it doesn't take much to warp the N7 screen.

Another concern is that an in-dash tablet would be a theft magnet. By itself the tab isn't worth much, but the smashed windows and bent door jambs will be expensive to repair.
[Nexus 7 General] curseddagger:
All has been taken into consideration. I didn't realize about the polarization but it looks fine through my sunglasses from all angles including the back seats.

I'm not too worried about the battery since it is always on charge. I may remove it if it swells due to temperature though. The climate where I live is not too bad and i always use window shades when I park the car, plus with the darkest tint on my windows that is legal and the location of the tablet, it will certainly not be in direct sun. Something to keep an eye on though and something for others to consider.

My car is more of a theft magnet than the cheapo tablet because it's a wrx with a custom paint job. All insured anyway.

Thanks for your input.
[Nexus 7 General] uberNoobZA:
You can do the same thing using a Garmin ecoroutehd. It connects to the diagnostic port on your car and uses Bluetooth to send info to a android app or a compatible Garmin satnav. Not sure on all the dials it can show. Will connect mode up later to my car and post some pics.
[Nexus 7 General] purple_duckk:
Are you sure you can't charge through the pogo pins and use USB OTG at the same time? I am doing the exact same thing and was planning on using the pogo for charging while connecting a thumb drive for additional storage. This may change my dash kit build 100%

Props for the fast quality build and the Scooby. Had a 2001 WRX myself a million years ago.
[Nexus 7 General] curseddagger:
Thanks :D

im not 1000% sure but i have been playing with it to no avail. Might be due to the charging circuit being so damn fussy about chargers and cables, etc.

p.s. i love the old GC8 series WRX, my favourite shape of all of them!
[Nexus 7 General] purple_duckk:
What are you using to power the pogo connection?
[Nexus 7 General] curseddagger:
I've used a variety of chargers (all in the car though) i havn't tried the original charger that came with the N7 yet though... might be something to try.
[Nexus 7 General] purple_duckk:
I guess I'm not following how you are going from the charging cable to the pogo connections. Are you cutting the wire up? My plan was to use an offboard power supply that has a 5v 2A output and connect it to some pogo pins mounted in the bottom of the dash kit. If it isn't going to work I don't want to order the parts from Digikey.
[Nexus 7 General] HKSpeed:
super cool. reminds me of a guy who put a samsung galaxy 7" tab in his car.

[Nexus 7 General] curseddagger:
Ah right, well i took a micro USB -> usb male cable and chopped off the micro end and bared the wires, tinned them with a soldering iron so the strands stay together and then touch them on the pogo connections.

If i ever get it working then i will buy the pogo pins from digikey and build them into the dash

also, just found this: http://rootzwiki.com/topic/30615-can-you-charge-usb-host-mode-simultaneously/page__st__10

looks promising
[Nexus 7 General] purple_duckk:
Ah, I see. Did you get it to work when the USB wasn't plugged in and then it wouldn't work after the USB OTG was plugged in? Im just wondering with it being so picky if the multiple connections and extra length are playing havoc with it.

Also, have you tried a line driver to help you eliminate the noise you seem to be getting? My build plan has an AudioControl Matrix to boost the signal before pushing it to the amps. I haven't tested it but I think the voltage coming out of the 3.5mm jack is REALLY low and that might be causing you to pick up noise along the way.
[Nexus 7 General] swan3609:
I posted a comment on your blog, but I am wondering. Could you show me how you installed your tablet behind the bezel in your subaru? I am thinking about taking out my DVD unit in my Forester and doing the same thing you have done, my only thing it that I would like to have it be removable.. I am still trying to figure out how to make that work..

Last thing is how are you running your audio to your speakers? You have an Amp mounted somewhere that you connect to the tablet?

Thanks!
[Nexus 7 General] curseddagger:
Hey,

I've updated the blog to show you how i did it. It is reasonably easy to remove, that dash panel just pops off in 2 seconds and the tablet can then be removed.

As for audio, at the moment its going from the headphone jack to my amps in the boot but i have a USB DAC and a DSP to bring up the audio quality as soon as I/someone work out the usb host mode + charging issue.

Cheers

[Nexus 7 General] stanleywinston:
Are you using a replacement dash unit? I've got the same car from the same year but a UK model. I have a row of switches (turbo water spray, headlamp wash, clock dimmer) and a single din stereo slot. I was looking for a way of doing this type of thing but couldn't find a suitable double din dash unit
[Nexus 7 General] swan3609:
Hmm looks like your method would work.. I am thinking about going to a junk yard and pulling one of those Bezels from another forester and try and see if I cant do some cutting and fab work to make some kind of system so I could take the tablet in and out easier.. I am not hip to having to pop the whole bezel every time I want to use the tablet..
[Nexus 7 General] Lockeskidney:
Any progress on getting audio out of the usb?
[Nexus 7 General] lankin:
OP,

Did you ever solve your grounding issue. Have you tried grounding the RCA's? I can't post links at this time but google "how to ground rca" and check out the realmofexcursion thread. Should be lots of examples out there.

Secondly, any luck with the pogo pins and usb connection being used at the same time?
[Nexus 7 General] Sengir:
Looking for the same but i can't neither charge the nexus via pogo pins! how did you do that?

[Nexus 7 General] Freshtojeff:
As a car diyer as well, very well done sir! Maybe I should ditch my RSN and grab an extra N7 for my Audi.

on/off button

very interesting, but as a Nx7 owner....

I'm wondering how you solve the on/off button probem, this is rear, unreachable.

I've tried some wake up sofware and it works pretty bad.

(turn off software make the job)
[Nexus 7 General] Croccy22:
Well this is my way around it and only time will tell how practical this is (Seems to work so far).

I use an application called Tasker. My Android tablet is connected to a usb car charger which only comes on when the ignition of the car is turned on.

So, If the tablet is running from a USB power source, then turn on screen, tell it to stay on, launch the Car dock app and make sure sifi/bluetooth is enabled.

If the power is cut to the tablet, Put it into airplane mode, set the display to timeout in 7 seconds etc. This makes the tablet use very little power and should allow it to stay in a stanby state for several days without a problem.

This will all depend on how often the car is left and driven throughout a week but so far my tablet has not dropped below 90% power.

The other option is to pull the tablet apart and hard wire the power button but I don't want to do that if I can help it!!!

Matt.
[Nexus 7 General] strongergravity:
Matt,

Way to make me think...I used to use Tasker, but then I started playing with NFC & my GNex.

Thanks for the inspiration.
[Nexus 7 General] barrmulio:
And if your phone doesn't have NFC just use one of those NFC pads on your keychain like these: http://www.sonymobile.com/us/products/accessories/xperia-smarttags/
[Nexus 7 General] intruda119:
Only if I could usb otg and charge at the same time. I was planning on using the nexus 7 but 16gb wont hold my music. Hopefully a 32gb or higher comes out one day. Or that pogo dock and then i would be in heaven. As of now, just using a samsung galaxy tab 2 7.0.
[Nexus 7 General] drhunter:
If /when i build a tablet into my car I want to find a way to do so with a backup battery so i could use it as a gps tracker if the car was ever stolen!
[Nexus 7 General] strongergravity:
I have NFC stickers & keychains...I'm covered, but thanks!
[Nexus 7 General] Psyklon:

Has anybody extended/externalized the Nexus 7 power button? If so, which contacts did you use? I don't really want to mess with the ribbon or it's header. It looks way too small for me to solder on to.

check out my professionally installed Nexus 7 in my 2011 Prius. I used a very sophisticated technology to mount my device in dash. It's called Velcro. I also used another really amazing, secret service called Bluetooth to connect my stereo to my tablet. It's AWESOME!

Install in a F150

I recently did something similar in my truck. It works fantastic. I’try and post some pics and a video in a little bit.
[Nexus 7 General] yellowfinii:
This is not a Nexus 7, but a Samsung tab plus, I’m considering getting a nexus 7 as I think it may be a bit smoother.

Heres a video of the final result: (sorry for the poor quality video, my real camera went bad, haven’t got a new one yet)

Not sure how to have the vid in the post. http://www.youtube.com/watch?v=BDNiw6AVzmI

Specs:

Tab Plus (1)

Tasker

Google Music

Torque

Torque widgets

Scantool.net OBDlink MX - can always leave it plugged in with the power save modes.

Behind the scene 120v power inverter so i can use “AC” power charging all the time.

Tablet is setup with taskrr so it turns on BT,WIFI, adjusts screen depending on time of day and displays the custom start up and loading screens while it turns on/off wireless stuff sets screen to always on, etc

When the truck turns off, turns off BT,wifi, turns off ‘screen always on’, displays turn off screen, some other stuff.

I get audio to the truck via BT. doing so all the steering wheel and dash controls work flawlessly. (play/pause, next, previous, etc) only wish android BT supported the audio info protocol (like pandora bt)

Heres some pics of the build:

Vacum formed a mold over the tablet to slide in & out, although it primarily stays in the dash.

Initial cutting of the dash panel.
[Nexus 7 General] cybervyrus8587:
That's cool... I cant b without my nexus when I'm out of the car so that's y I just made the mount I did. Although my next one will have to wait till I get the note 2 cuz it too will have a place to call home on drives :cool: it will b epic! But for now this will suffice. On a side note I know u can't tell on the video I posted but the sound clarity is superb. Still have left right front and back so the direction of music is apparent. I still need to upgrade my door speakers and tweak some stuff. Then I'm gonna get either a single 12/15" mofo in a custom box and beat the crap out of it.

I wanted to ask ... where did u get the vac work done? That would have taken loads of time off mine.
[Nexus 7 General] Omyn:
Ahhhh.. Tasker seems to be the app I've been looking for. I always knew there had to be an app to do some of these things. I have a question, will it be able to kill apps as well if it loses power to the charger. I often have poweramp running and playing music when I turn off my car and I would prefer it to either pause the music or kill the app when I turn off my car.

Here is a link to my install.

http://xdaforums.com/showthread.php?t=1967151
[Nexus 7 General] dmexs:
Yes it can kill apps. You can also simulate media button presses to pause and play the current song with change instate. Nice install BTW!
[Nexus 7 General] Omyn:
I found that feature for simulated media presses. It works better than I could of imagined. I'll probably be holding out for the 32gb Nexus 7 before I replace the Nook. I appreciate the kind words about my install.

I wonder if there is a way to do a backup camera. Maybe a wireless IP camera or something that would trigger an event in Tasker to bring up a live feed... Hmmmm....

can you share how you have it set up to change the screen (brightness i'm guessing) by the time of day?

Wow really cool mods guys!

My 98 mustang has a huge din since the cd player and radio were completely separate gonna go to the junkyard and pick up a spare bezel to try this out
[Nexus 7 General] samotronta05:
I'm currently working on a whole set of soft- and hardware in order to use the Nexus 7 as Mediaplayer in Cars, Kitchen-furniture etc.

It mainly consist of a small 8-Bit microcontroller and a bluetooth module to connect to Nexus 7.

You can connect momentary switches to the microcontroller for waking the device, next and previous song, starting and stopping music and for switching between music, navigation and Internet, as well as an encoder for changing the volume.

If you are interested I can post more information and pictures.

[Nexus 7 General] zedix79:
Nice build! I'm doing the same right now in my Impreza 2010. Any idea how to get around the very hard to reach power button?

I'm doing the same thing with Tasker where it will basically put it in airplane mode when power = off, but not sure how to handle the case where/if the tablet would completely power off. Would suck to remove the bezel just to reach the power button.

Any kernel mods/apps that would make the tablet power on automatically when USB connected?
[Nexus 7 General] yellowfinii:
I made a discret push button on my bezel extending the power button. unfortunately the hazards and Traction control buttons are in the way for the volume rocker otherwise i could flash roms in place.

Thanks for posting that...so you have it at max brightness from 8AM to 7PM (if I'm reading that correctly)
[Nexus 7 General] yellowfinii:
Thats the one issue which is a concern, i use a quiet 120v a/c adapter on am ignition relay to power the tablet since i cant get fast charge/A/C power charge on usb. right now it seems to just be slowly getting a lower battery, i dont think i spend enough time in my commute to catch-up the charge. how ever it has not yet died with tasker
[Nexus 7 General] zedix79:
I'm in the same boat, hoping the tablet won't die, but it *will* happen at one point and don't want to remove the car bezel to hit power ever time.

Extending the power button definitely sounds like a valid solution; I was hoping there was a software solution. I was able to find a rooted app that does that but it seems only compatible with Samsung tablets...
[Nexus 7 General] yellowfinii:
What app are you referring to?

Yes, max brightness from 8AM to 7PM

I need to update that now that DST is no longer in effect. I'll probably do 7am to 6.5pm (if 6.5 works)

Quick question. Anyone having issue with noise/feedback when charging and playing audio at same time. Before i waste tons of money figured i would ask.

Have a ground loop isolator coming tomorrow. Hope will fix. Audio wiring was done correctly.
[Nexus 7 General] cybervyrus8587:
I have the most faintest of wine with no ground loop. You only hear it when no music is playing. I just grounded everything to the same point. The only time I get bad feedback is when I'm using my Bluetooth adapter while charging... I think its b/c its grounded on a diff point.
