Nexus 7 car install build thread

[nba1341]

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

 

[samotronta05]

very interesting, but as a Nx7 owner....
I'm wondering how you solve the on/off button probem, this is rear, unreachable.

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.

Had some guys make a bezel from a double din kit. Looks crazy good and i can take out easily. Currently working on getting my audio setup now.

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

Yeah, here is my profile export i have.

I dont know if this is the best way to do it, it works thou. I may play around with other ways to do this - particularly to have it adjust continuously instead of just at the task activation. (recalling, i'm not sure if it continuously checks those actions, i dont think it does thou)



And for anyone interested how I have tasker setup:

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?

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)

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

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...

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.

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.

My feedback isnt extremely loud but i would be fighting it trying to talk over without music playing.

Ill post if the ground loop isolator fixes my issue.

Only feedback i can hear is when the volume is turned more than 5/8's the way up and playing no music or audio. I use the Bluetooth from tablet to the receiver.

Well like I said , mine isn't very not very noticeable and u can't hear it when music is playing at any level. I'm curious to know if a GLI would work... b4 I did my stuff I did tons of research and found that many still had noticeable wines or feedback even with a GLI. I plan on making a custom ground block I saw on lifehacker to ground everything to including my lighter ports to c if that'll take care of feedback when charging and using my Bluetooth adapter.

By the way I'm not running my stuff through a radio

[intruda119]

No radio here either. I cant hear anything from probably 25% and up when audio is playing. But without audio whine gets louder the lower the volume. Im using a good quality bass knob to control volume.

I post feedback sunday. I purchased the wrong item through amazon with first attempt.

Im also using a galaxy tab 2 7.0 at moment. This is the most active thread i can find and with tablet installs being fairly new its all trail and error. Thanks for info i might try the lifehacker thing.

Yeah got the ground loop isolater and noise is 100% completely gone. Item cost me $ 10 off amazon and works perfectly. Can charge and play audio without issues.
