Nexus 7 tablet in-car install

I guess I will have to get different sunglasses that are not polarized, or if I do, they must be at a different angle than the nexus 7.

Not sure if this is an issue with anyone else, but wanted to bring it up.

i have the exact same issue here in Phoenix with my Oakley FastJackets. i had to switch back to my Smith's for the WRX driving and keep my Oakleys for the 911.

So i had a thought last night and I got to working on an animation that plays everytime I start my car. I set up tasker to play a video that I made so it appears as if the Nexus 7 is booting up when the car starts.

Here is a screenshot of the animation.

I didn't read through all the pages in this thread, but I thought I'd mention.. For those of you who are retrofitting 12V sockets and using car chargers as charging options but have the issue of the limitation of charging amperage, if you short the two data pins (solder works best) on the charger Android devices will recognize the charger as AC, and will allow for more current. The data pins are the two middle pins on the typical USB A plugs/outlets.

Evidence over at XDA developers show that shorting the pins makes no impact to the amount of current that the Nexus 7 will draw. It only affects whether the tablet shows "AC" or "USB". For what it's worth, I tried shorting the 2 pins on my USB charger and it had no impact.

I was able to get a larger charge after switching to an OTG usb adapter, a Y connector, and running the custom Charging OTG Kernel.

Charging is now at close to 900mA under heavy usage. Not to mention the benefits of running a 5 port hub.

Zedix. Have you seen that other guy, that made the sweet plexiglass backing + reusing a holding case.

Absolutely, posted in his thread. Awesome worksmanship. Major difference is that his audio runs through BT and a Parrott device as opposed to a full HU.

Interesting! I actually only use it for my Galaxy Nexus phone but it keeps me in the positive. Before it I was getting minimal (no where near 1A) charge. Thatasaid, perhaps it is quite different for the Tablet since the battery capacity and rate of consumption/charge is vastly different. I was also kind of surprised that it charges through USB alone as well, since some of the older (albeit larger) tablets go through a standard coax power connector.

Battery finally was 100% dead when I started my car.

The bootloader fix worked perfectly, once it detected USB power it took care of the reboot process.

Found this for those of us who are waiting for something with an external sd card (although I hear samsung is cancelling their plans on another 7") and use spotify (since those ass hats took away our external sd storage option about a year ago)

checked out the Samsung galaxy Tab 7" at Costco for like $185 for the 8GB version. no additional charging port, but had a microSD slot for storage and the profile appears to be nearly identical to the Nexus7. that's a cheaper option and entry price for those of you thinking about doing this. microSD cards a much cheaper option than the Kingston Wi-Drive that I bought to expand my storage.

sidebar - ordered BT OBD2 adapter, 1ft microUSB right angle cable (to help with charging) and also going to have a high amperage cigarette lighter adapter ready to be wired in should the need arise. since i haven't totally nailed down the mounting yet, i may also yank the wiring harness that i did and clean up the connections now that i have sleeving and an assortment of heat shrink tubing, make it a little cleaner in there.

also returning my 32GB Wi-Drive and have a 128GB one on the way.

That's pretty awesome. Any chance you have a host for that file so we can all (looks around)... uhh... borrow it?

128GB Wi-Drive received and up and running. 32GB returned. 1ft Star-Tech right angle Micro-USB received and charging MUCH better now. Also threw a screen protector/anti-glare filter/anti-smudge cover on the screen. looks MUCH better than the glossy finish, and is going to be great for this application of the Nexus 7.

Also got a micro ELM 327 adapter and downloaded Torque. Should be pretty nice!

Don't know why it says 4 amps though although my galaxy note 2 OEM AC unit is recognized as ~4amps as well even though it says 2 amps on the charger

You're not reading the graph correctly. Approximately 25% an hours on a 4Ah battery is 1A charging input. The only thing that says '4' there is the battery size.

[sabregen]

shortened cable helped with charging. getting +~500mA now. haven't quite figured out Torque yet.

[chitownbugi]

really cool! my friend had a setup like that in his TL but it was mounted in a lower spot instead of replacing the head unit!

For anyone who would like the WRX animation, I can email it over. Feel free to PM me your email address for me to send it to. The video is under 5 MB.

I can also make an STi animation if anyone would like it.

Yes on the sti animation

I will work on it tomorrow night. I am assuming you would like the sti to be red.

Is that a start button on the console?

[fordskydog]

I found a deal on a Lenovo Thinkpad A1. Cool thing is it has an fm tuner built in. Bonus. I will relocate factory nav headunit (not very fond of it, or satellite radio) and run tablet audio to it. I will pair my phone with tab and factory unit so calls come through, and so the interwebs are shared. Already have Torque Pro set up with the obdii dongle.

software and solutions to find:
-good main ui. seen several around. KITT? probably
-how does fm tuner work on that thing?
-write macros if needed to automate all the wireless handshakes required.
-upgrade tab to 4.0x or cm7, mainly for better voice recognition/root. always on voice rec?
-pair sixaxis controller and setup some games, mainly to impress brother
-keyboard? dammit. do I need a keyboard in my car now? probably not... use phone as mini keyboard? that would be cool
-hey! I can use that traffic/camera/radar database now! sweet!
-it would be great to have a map/traffic/weather overlay going on
-set up rss feeds for weather and aggregate podcasts for the morning commute
-how bout use my wifi outside the house to grab feeds to cut down phone data usage
-app to let tab place calls on phone
-setup Five Guys app. sweet

pipe dreams:
-wireless charging mat for phone. theoretically possible. seen a diy
-wireless (hell, wired) openport interface. flash different tunes from the car! that'd be schweet
-wireless cam? be great to use the video/telemetry record on Torque. phone's camera on windshield mount?
-peep cams on bumpers
-drive car from phone/sixaxis
-50 more torqs

Just add A NOS sticker to get that! lmao

As for the rest of your list sounds like a bad ass set up if you can get it all worked out. I've gotta get my car running cuz i have tons of ideas for this too
