Yes, but I don't shut it down. I have it sleep instead. I have a tasker profile that disables all radios and kills running apps then sets a short screen timeout. In my setup, the tablet only has power when the key is on (switched power).

I found that it really doesn't need to shutdown. The battery only drains less than 5% at most overnight.
[Nexus 7 (2013) General] Evo3dUser:
I'm a bit confused now. If you don't shut it down then what does the bootloader command do as it is supposed to power on the tablet from a completely shut down state, isn't it? Also, can you share your tasker profile to put the tablet to deep sleep. My problem is the battery drain. I don't drive my car much and even when driving my battery is always draining during use even though I'm charging my tablet through a powergen charger. Thanks.
[Nexus 7 (2013) General] dimex:
I have mine shutdown every time. Works great.
[Nexus 7 (2013) General] pistacios:
I have the bootloader command in place because it is mounted in dash, I cannot access the power button. Just in case I do decide to shut it down (with a "power off" on screen widget), it will turn on when it receives power again.

The tablet should go to sleep on its own once the screen is off, provided there aren't any apps running in the foreground. I'm using clean rom (I'm still on KITKAT version) + elemental x kernel.

Hi,

I want to build the Nexus 7 2013 LTE in my car.

Ignition (connected with a 12V-5V DC-DC converter over OTG cabel with the Nexus) should turn the Nexus on and off.

Everything is connected over a 7x-USB Hub. (e.g. the Behringer USB DAC)

When I disconnect the 12V, then reconnect it and try to start playing music the sound comes out of the Nexus speakers and not out of the Behringer USB DAC as it is supposed to.

When I then disconnect the cable from the Nexus and reconnect it, USB audio is working again.

It seems like Android doesn't recognize the USB devices anymore once the voltage is disconnected and the reconnected.

Does anyone know if there is a solution to my problem? Like an Android/ ElementalX setting?

I have tried with Android 5.1.1/ ElementalX 4.05 and Android 6.0.1/ ElementalX 5.05/ 5.07 so far.

Thank you.

Hi guys, I have installed the nexus in my car but I have been having charging problem. I get a very slow charge and now I think I know why. I am using a few micro USB extensions and cables and I think it's because of those low quality after market cables that I am not getting a full charge or even no charge sometimes. I read somewhere that the 28/24 guage cables are good. Any idea where I can get these?

Due to my configuration, I need the following cables:

1. 90 degree right angled micro USB cable extension.

2. Regular micro USB cable extension.

3. 28/24 guage otg hub extension.

Also, is it possible to charge and use otg function both using an otg hub/cable at the same time?

Thanks

Is there any kernel other than timurs that has otg charging on boot?

I've tried elementalx, Franco and quanta

When I turn the ignition on it turns on power to my USB hub which turns the tablet on from an off state with fastboot oem off-mode-charge 0. The problem I'm having is once the system is booted to the homepage it doesn't see it as charging unless I turn the ignition off and on again to turn power on the usb hub off and on or disconnect and reconnect otg cable(behind dash so not accessible) then it will show that its charging

I was hoping that it would show that it's charging on boot and then when power is turned off the tablet shuts off with tasker.

Hey guys I just got a Nexus 7 and I have an 08 Ford fusion just wondering if there is a way of keeping the steering wheel controls, I have the system that has Bluetooth and 8 speakers also sync , but as long I as can get Bluetooth on the tablet I'm good with that and what I mean is to connect my phone to the tablet and play my phone's audio on the tablet
[Nexus 7 (2013) General] tesna:
Unfortunately currently only timur's has those functions working properly so far. I was in your position very recently, thinking of making custom OTG cable with a switch (to enable/disable OTG) with the switch has easy to reach location when installed in the car. But in the end I decided to get timur's. It's always works.

My experience with other kernels was the OTG must be connected after system boots to get charging + usb audio working properly. After powerloss then power back on sure the systems wakes up via tasker.. but usb audio stopped working. I had to disconnect the otg from the tablet and plug it again to make usb audio working again.
[Nexus 7 (2013) General] FrenchSparda:
If there's some devs/compiler or someone with some knowledge about android & kernel interested to develop, compile a ROM with Timur's features, help would be great since his sources are available. A MM, or CM ROM would be great. So if you're interested, pm me, so we can have a talk, but dont ask me the sources yet. It would be great to make a team and bring to N7 a great ROM for car installation.

I've had the nexus 7 installed in my car for a couple of months now but I've been having charging problems. First I was using elementalx kernel and then decided to install the t1mur's kernel hoping to solve the charging problems. But the tablet is still not getting enough amps. It is averaging between 200-300mA and goes negative if I'm using apps like Google maps, waze or play music etc. One time it even showed -900mA. I've come to the conclusion that the problem may be with substandard USB cables. I'm using the following components/cables in the following sequence with the tablet:

1. 90° micro USB male to micro USB female connector.

2. Generic micro USB male to micro USB female extension cable.

3. USB otg hub. Connected to the hub are a USB thumb drive and easycap capture card for rear view camera.

4. HTC OEM micro USB charging cable.

5. Powergen charger plugged into the cigarette lighter outlet.

I think that #1, #2 and #3 are the source of the problem as they are generic with low quality cables.

If any of you know about better quality extension cables and otg hub please let me know and share the links. Or any other suggestion/solution.

Thanks in advance.
[Nexus 7 (2013) General] tesna:
I was in similar position before. I was using setup similar like this:

Sometimes I get negative charging using that setup, especially when running google maps.

I use few tricks, from buying another otg y cable (3 of them!!), changing the DC-DC adapter, and replacing the micro usb port on the nexus! but none of them permanently fixed the random negative charging rates...

then replace it with something like this:

and it has been working fine so far *fingers crossed

Actually I was almost do the battery removal mod (and wiring it directly to the car battery) so I won't deal with charging issues ever.. I already bought the tools.. but thankfully the last trick is working fine so far. If negative charging happening again for sure I will do the permanent battery removal mod.
[Nexus 7 (2013) General] dimex:
You guys all really go to great lengths modding the tablet, removing the battery, etc.

Just enter the bootloader command, have the tablet start up when it receives power, and shut it off after 30 seconds when you leave your car. Sure, it takes 30 seconds to boot up, but considering you likely automate everything else like connection to your phone if you're tethering internet, it's really not a big deal.

I've ran my setup like this for 2 years now. Or just keep flashing kernels, stressing about your battery life, and cracking open the casing to do ghetto electrical work. To each his own.

---------- Post added at 10:35 AM ---------- Previous post was at 10:18 AM ----------

Losing charge overnight is not the issue. It only loses 2% overnight with T's kernel. The issue is not getting enough charge while driving while using multiple apps. I guess you also don't use an otg hub? I need that for backup cam and the thumb drive. But thanks anyway for your suggestion.
[Nexus 7 (2013) General] tesna:
There are two part in the second picture.

The first one is just regular OTG cable, but look for the thick cable between the male micro usb port and female usb port.

Quick search on ebay But this is not exactly what I bought (I bought in local marketplace here locally)

And second one is USB splitter cable (to add power from dc-dc adapter)

QUick search on ebay again.. this is not exactly what I got, but pretty similar.

I also got USB hub connected to it.. I got fioo e10k usb DAC, 32gb thumb drive, DVB-T2 tuner. Yet to find easycap for reverse camera...

Just want to share my installation :)
[Nexus 7 (2013) General] BassfacePD:
Hey folks,

I was just creeping around on the thread and realized I might have something to contribute to a lot of you who are posting about battery issues. I don't know if I missed something 5 or 10 pages back, but the first and best solution that I've had for charging my Nexus 7 is a cheap wireless charger that I got from Amazon. I just plugged it into a powered USB hub that was wired to my 12V cigarette lighter wires, behind the dash, and it keeps my N7 at 100% pretty much all the time! I have never had it die on me on the road, even when using google maps for several hours while listening to streaming music over wifi.

But to get to my real question, I've noticed that when I plug in my Note 4 through the headphone jack, the audio quality is noticeably better than my primary audio device, the N7. I always plug in the N7 the same way, through an aux jack, but the clarity just isn't there. I'm on the latest MM and I tried installing v4a to no avail, it doesn't seem to have any effect (yes I'm unlocked and rooted). Does anyone have any input on what DSP or EQ to install for a car audio setup, that works with rooted MM?
[Nexus 7 (2013) General] Evo3dUser:
Just to report back for those who might be interested. I bought this USB otg hub:

http://www.ebay.com/itm/Micro-USB-M...977770?hash=item2ca886f4aa:g:NO0AAOSwuAVWwAAO

Didn't notice much improvement in the charging and I was also having problems with my rear view cam. So I plugged the old generic USB otg hub back that I was using. And surprise surprise now for the last few days the battery is always at 100%. It seems that N7 has a mind of it's own. Sometimes everything works perfectly and sometimes some things don't work. Still have issues with the rear view cam some of the times, but I think it has more to do with the easycap app and the video capture card, as sometimes the app does not read the video input from the card and does not auto start. When I unplug and replug the card from the otg hub a couple of times then it starts working.
[Nexus 7 (2013) General] BanBoo:
I've noticed that the DAC of the N7 is pretty weak. Use Bluetooth instead. If this is no option try an USB DAC. You won't get good sound out of the headphone jack... at least for me it sounds really bad.
[Nexus 7 (2013) General] tesna:
As wireless charging, good to know that it worked great! sadly I cannot try this since I have the original head unit at the back of my nexus 7 (with 2mm clearance?) :( But so far my last method is working ok (fingers crossed)

As the sound output.. try USB DAC.. I use fioo e10K on mine and whoa it has improved the SQ a lot compared to the nexus 7's headphone jack.

Tasker

So my phone has android 5.1. Droid Turbo with Verizon. I have been trying to setup tasker to enable WiFi hotspot when it bluetooth connects to my head unit. But, it always says that the action failed. I tried both Tasker and Locale with no success. Any suggestions to get this to work? I did a lot of searching on this, but all of the threads were old. Seems that this used to work before Android 5.0 but since 5.0 all of the methods I found online do not work.

Anyone have a working microphone input?

I'm using a behringer uca202 DAC and I tried wiring up the factory microphone in my 2005 Mercedes Benz E320 CDI and plugged it into the DAC input but had no luck with it working.
[Nexus 7 (2013) General] BassfacePD:
The USB hub has several other things attached to it. I have a dashcam that runs on it, the wireless charger, and two usb charging cables coming out of it. One of those powers the wifi hotspot, the other is available just for if I need to charge my phone or any other device. As far as the OTG mode goes, I actually don't even have anything connected to the USB port... I just snap the n7 into the case, and plug in the headphone jack. Everything else is automated by an NFC tag that I have on the case, so it automatically puts the tablet in my pre-set "Car Mode" which has bigger icons, optimized layout, big clock, and custom EQ settings. And just an update on my previous post about sound quality, I installed a custom rom that has Viper4Android and it has made a world of difference. My Jeep was a little bit to bass heavy (with a 12" sub I understand why) but with the eq tweaked to favor treble, the quality is much improved.
[Nexus 7 (2013) General] njgalaxy:
yeah, i don't think the wireless charging works once it's in otg mode, unless you're running a custom kernel/rom.

btw, does anyone know a relatively "stable" kernel which allows charge+otg and is also free? :o

[Nexus 7 (2013) General] steeven01:
Hey no I don't have an easycap I thought those were for cameras.

Turns out the Behringer uca202 only accepts line level inputs so I would need some kind of 12volt mic preamp for it to work with my factory mic.

I ordered a cheap USB mic to try because accord to this USB mics should work.

When it comes I plan to take it apart and try wiring up my cars factory mic to the DAC inside the USB mic and hope it works.

I've been running into the charging issues a little bit, but mine are due to it trying to stay awake all the time. Running the elementalx kernel. The nexus is installed in the dash of my 05 acura TL. It was going to be a test fit that ended up semi permanent. I put in the oem charge mode 0 at fastboot and even when it does die it boots up in about 3 min.

I just wanted to throw out here I don't think im having issues with it charging more than draining as I drive because I have it hooked up to a very good fast charger.

This one specifically: AUKEY Car Charger with 36W Dual Quick Charge 2.0 Ports and Micro-USB Cable for Samsung Galaxy S7/S6/Edge, Nexus 6, iPhone and more https://www.amazon.com/dp/B0144S0PDK/ref=cm_sw_r_other_awd_WdEgxbJKDF58C

I didn't install a DAC so the tablet is connected via Bluetooth and it's the only thing charging from that port. Might be worth a shot finding a good fast charger. Any case it's coming out of the car tomorrow as the Acura is totalled due to the biblical flooding here in Houston. :(

I was having ac issues and I'm pretty sure the nexus baked in the car. I just picked up a 2001 miata and I'm not cutting corners. I'll be revisiting all this in a week or so.
[Nexus 7 (2013) General] firewater88:
I have turned off the dash cam recording and now it can keep up to 100% charge all the time. I was not using an OTG cable like another member said, just straight plugged in. I like using the Torque app load every time the car turns on, but may have to go to dedicated gauges if it really craps out. Already looking at getting a separate dash cam, just liked it built into the tablet since I could just upload the files I wanted to keep easy.

Interesting to see your final install in the Miata
[Nexus 7 (2013) General] Jacobh25:
That would do it. The last build I ran had maps, Spotify, waze, and maybe 2-3 more apps. I had the max cpu speed cut down as well. I was kinda defeated at the end there.

Torque is cool and I can spend 4 hours sitting in my car playing with it but I know it's a resource murderer. Run it off a $50 burner phone if you don't want to get the gauges you are reading. I thought about that with the Acura.

The miata has the bose audio system in it. I'm probably scraping all of it as the nexus will be the head unit running ARISE the viper4android build that's going gangbusters right now. I'll keep you guys up to date. :)
[Nexus 7 (2013) General] firewater88:
My Ford Flex has the built in Nav with Sync, which is a blessing and a curse. Can't replace the head unit as it drives everything, including climate. Don't use audio out of the Nexus, but stream bluetooth to the car from my Moto X. I have unlimited data, so I have it kick on hotspot when BT to car which the Nexus picks up- really only needed for Waze. The screen size of the Nexus is perfect for me, does not interfere with viewing on the dash. Besides, wasn't really using it as a tablet anymore. Maybe I'll use it more when Android Auto comes out for use without a capable head unit. Tried a few apps and tricks on here to get a workaround, just too flaky. Miss Viper4Android when I had my Note 2 mounted in my truck, sure made a difference.

Good luck with your build

[Nexus 7 (2013) General] DarkFoxDK:
What's causing trouble, is probably the voltage drop from the starter. So from the tablet's point of view, when you turn the key, the power will come on shortly, then disappear, then come back. That tends to mess things up.

Easiest way might be to use a Bluetooth adapter as the "signal wire". If you have a Bluetooth accessory powered upon key on in your vehicle already, set up a Tasker profile to trigger the N7 when the Bluetooth connection is made, and shutdown or sleep when the Bluetooth connection is lost.
[Nexus 7 (2013) General] Deeco7:
Hmm, not a bad idea. But, although my build is removable it will mainly stay in the car, so bluetooth would be on all the time.
