Yes, it works that way, I was also puzzled at first.

But I still only get about 800 mA charging rate. Even connected directly to original Nexus wall charger, OTG or not, original or special 20AWG cable: nothing more than say 810 mA. The charger is rated 2 A...Is this a limit od Timur/kangaroo kernel?
[Nexus 7 General] MReprogle:
What exactly are you using to get sound to your subwoofer? All the DACs that I have seen push audio through 2 RCA cables, which at that point would have to be put into an EQ in order to split the audio into 4 speakers and one subwoofer.

Hi,

I had two of this and connected it to my PDX-5 amplifier: http://www.amazon.de/gp/product/B000PENIQY
[Nexus 7 General] ch_bla:
Digging this out as I currently made a similar setup :)

Two questions:

- Are you using a rearview camera as well? I've got one connected but I'm trying to find ways to switch it on/off when I put in reverse.

- Are you using it for phone calls? Looking for suitable handsfree sets and remotes..

Thanks for the list!
[Nexus 7 General] rhipone:
i hope this thread wake up :P

mine is this

Hi everybody, first of all, english is not my main language so sorry if i dont speak it very well.

I got a Nexus 7 2013 wifi 5.1.1 on my car. Actually my configuration is this:

Nexus 7, Y cable, one to an USB charger and the other to a HUB( normal one)

I use ElementalX kernel for OTG + charge, because if not, doesnt work.

I have this problem:

When i connect my car( dont start it, just place the key) the tablet start, i change one command with fastboot, and if we wait until the balls start floating I start my car the tablet charge, if I dont wait, it doesnt.

Now, the tablet doesnt recognize me the USB.

I use stickmount, total commander, usb plugin, es file explorer...and i cant see my USB, so, can you tell me wich is the best option?

I got another cable, normal one, so i can place:

Nexus, cable, HUB and connect one USB between the charger and the HUB( really is connect one USB from the charger to the hub, and the hub to a micro USB - USB female)

Please help!!

How did you get Audio Glow to work?

I have installed the latest kernel from Timur but Audio Glow doesn't work.
[Nexus 7 General] JakeOrth:
Phil! Hi from Spain!! Sorry my poor english.

I have a Nexus 7 2012- First Generation. Only WIFI, not 3G.

Do you know where can I get the Timur Kernel???? I become crazy, I don´t find it!!!

Thanks a lot

Does anyone use a 4G USB dongle and can confirm that it works on Nexus 7 2013 WiFi with Timur Kernel?

I'm currently using 3G Huawei e3131 modem and PPPWidget, but I would like to replace it with 4G Huawei e3372

AW: Nexus 7 car dash install + OTG charge + DVB-T + DAC + OBD + Webcam

Hello Kookie_Monster,

thank you for your reply and the visualization app link! I read it anywhere before, but its good to read it here with link, so i will add it to my list!

It's snowing in Germany so i am going to continue next week. Then i will have it in my car, hopefully ;)

I have to look for some material to mount the nexus behind the double din frame.

What about using a bracket mount available online ?

I live in Germany also. I just bought a Honda Jazz and a Nexus 7 with 3g.

My plan was to buy a Navigon windshield mount but couldn't find it so I am going for a Brodit Nexus 7 mount and use the Car Aux jack for sound.

This seems like the most cost efficient solution available now to allow the Nexus 7 to be used for Navigation, In Route Skype Calls and Music.
[Nexus 7 General] Kookie_Monster:
No problem. Be sure to keep us posted mate. :thumbup:

N7 and Torque during sleep mode

Don't know if anyone have encountered the following with Torque (Pay version) + BT OBD + N7

I have been using Torque on Galaxy Note (N7000) without this issue for one than 12 months, then I purchased N7 3G and migrated everything to it without much issue but then I discovered some strange behaviors

The following two testings were carried out

A: The setting in "Data Logging & Upload"/Discard Trip < 0.5 miles is unchecked and "Ignore short gaps between trips" is checked.

My car stopped for 3 hours with engine stopped and I walked away with my N7 but without waking it up, the logging continue after I started my car and the logging didn't start from beginning and continue from last journey

B: The setting in "Data Logging & Upload"/Discard Trip < 0.5 miles is unchecked and "Ignore short gaps between trips" is unchecked.

My car stopped for 4 hours with engine stopped and I walked away with my N7 but without waking it up. When I returned to the car and the logging won't start but all ODB statistic and data are normal, the connection to my BT ODB is good !

C: All seems normal if I play with my N7 between the stop, the logging seems to start itself when my car starts

Is it something to do with how the Torque/N7/Android calculate the time during sleep mode ? So when I check the ignore short gaps (10mins) the program didn't calculate the actual time gap if I didn't play with it as in A. So it just continues to log with last journey without knowing the time gap.

Any advice apart from playing with my N7 in between ?

Nexus 7 installed in car! finally ;)

Hi!

Today I have finally installed my Nexus 7 in-dash!

It is not perfect, but I wanted it TODAY.

I think i am going to try glass-fibre to mount it in the back of my double-din frame next week.

Then I am going to cut away the plastic bridge, so the Nexus comes forward (see my pics, 2nd post). Maybe even the reception will be better.

GPS + 3G seems to work fine right now!

In sunlight, the display reflects a bit.

Maybe I'll turn it a little at me when I try the glass-fibre mount.

I've never done anything like this so I have to read some..

Please do not laugh because of my construction, i know that it is not good :p

New pics will be up in the next few minutes..

I am also looking after a rca-volume-control. Better than touch..

DVB-T & SDR doesent work at all.. :(

Old version of SDR Touch worked, though buggy..

DroidTV never worked for me because of Timurs kernel (driver compability).

greets, phil
[Nexus 7 General] t1mur:
Hi Phil, to be fair, Timur's kernel never intended to support DVB-T. But USB ROM for Nexus 7, which includes Timur's kernel, has all available DVB-T kernel drivers enabled, allowing the use of DroidTV. You can even combine DVB-T and USB DAC operations. Video prove: http://rootzwiki.com/topic/37755-ti...ost-power-management-usb-audio/page__st__1210 (4th message on that page.)
[Nexus 7 General] PHiL_G4:
Hi t1mur!

thanks for info! I know that it is a driver thing, and i have to compile it on my own for the kernel i have in use!

But I never did something like this before.

I have already seen the USB ROM, but thought it will be overkill for me (nearly 175MB?).

Your FI kernel rocks! When i am ready and have daily usage experience i will send you a few beers ;)

When i am going to try the USB ROM, which one is the right for me with stock chainfire autorootet nexus7 3G?

This one: cm-10.1-20130216-USBROM-tilapias.zip	3G	4.2.2 ?

Thank you :good:

//edit:

i ordered a volume control: http://www.caraudio-store.de/Level,Control,mit,Cinch,EinAusgaenge,Autoleads::::9666::::8bff7fdd.html

and a micro usb extention cable: http://www.ebay.de/itm/230937741588

..to place the micro usb in my glove compartment. then i can change between OTG cable with usb hub and so on or a standard usb cable to my notebook to flash new software etc...
[Nexus 7 General] Kookie_Monster:
Hey Phill... nice to know you got things going!! :good:

Regarding the micro USB extension... unless it has all the 5 wires connected (which I didn't see indicated on the link), you won't be able to use the OTG cable. You should try the cables from this company: http://www.usbfirewire.com/uextendmicrob.html

They're a little expensive but very well built.
[Nexus 7 General] PHiL_G4:
Hi Kookie_Monster!

ahhh you got me! This I wasnt thinking about..

Thank you for this tip. Nevertheless I will wait for the ebay cable and will see.

Because the pic shows 5pins:

But who knows...

I will report when it arrives!

Bootloader mod?

It was stated in OP's first post that the line: fastboot oem off-mode-charge 0 will set the device to auto power on instead of charging. But being a real goddamn noob. I cannot figure out how I am supposed to modify this line. Does this require me manually modifying my bootloader? Any suggestions on how to do this would be greatly appreciated. Thanks!
[Nexus 7 General] PHiL_G4:
Hi!

It is a fastboot command. So, you have to go in bootloader mode first.

with adb: "adb reboot bootloader"

then

"fastboot oem off-mode-charge 0"

android-sdk is required to have adb & fastboot

regards

phil
[Nexus 7 General] daclothe:
did that ebay cable ever come in phil?

For steering wheel controls...

Make it easy and use the Joy con Explorer EX circuit board. Works flawlessly for exactly what you'd like to accomplish. Been using their products for years with x86 infotainment builds and works flawlessly with android OS through OTG for media&system controls.

[Nexus 7 General] PHiL_G4:
Hi stevey500,

I do not have steering wheels controls in my "car".

Second, an arduino is cheaper and works directly at the usb hub (power+hid usb control) ;)

I am thinking about where to add pushbottons... dont know..

phil
[Nexus 7 General] daclothe:
sorry to hear that...:crying:
[Nexus 7 General] Kookie_Monster:
Hate to say "I told you so"... lol :(

You should check that link I left the other day. I ordered one from them on April 1st and I'm currently waiting for it. That's the final piece of the puzzle, as I have everything else needed to complete the installation, hardware-wise.

Edit: I just noticed you're from Germany. During my researches to find the best things for the install I found a German company called "Delock". Their cables are top quality. I just don't whether they have micro-USB 5-pin extensions. Would probably save you a few weeks, as the usbfirewire cables are shipped from the US.
[Nexus 7 General] PHiL_G4:
yes, i know mate :)

pls tell me if it works!

then i am going to buy one too.

SDR Touch works fine, N7 is mounted fine, DAC works fine, I am at the DVB-T (droidtv.apk) Stick.

I need the rtl2832u driver for my dvb-t stick and actual kernel "3.1.10-gfcf72bf-dirty".

Perhaps I will find some time this evening, to read how to cross compile this for actual kernel.

never made things like this before.

Phil

// edit:

thank you very much for this.

my usb hub is from delock and I am quiete happy with it.

I did not found an angled one, only the straight plug..

thx!
[Nexus 7 General] Kookie_Monster:
You're quite welcome... :)

I know the cable works. There's a guy over at Rootzwiki that has a thread of his own... and he's using one. Says it works like a charm!

Audio quality?

I heard using the N7 for a head unit with an amp had terrible sound quality, is this true?
[Nexus 7 General] pixlgeek:
This is fantastic. I have a Smart as well and I am looking to do this exact same thing. I have a question:

Assuming I have the factory radio. How do I go from the wiring harness that comes from the car into the 3.5MM headphone jack on the tablet?

There are 4 cables I believe (Driver Tweeter, Driver Main, Passenger Tweeter, Passenger Main). How do I convert these 4 cables into a single 3.5MM jack?

Thanks!
[Nexus 7 General] iraymanl:
Mine's going from the N7's headphone jack, to an iSimple, to my stock HU, to amps, and sounds fine.

I'm tempted to try an external USB digital audio converter (DAC), but, I feel that all the concerts I've attended will make me not hear a difference.
[Nexus 7 General] f_speed:
Very nice work!

Hi everyone,

Glad to find this project here, I'm doing the same with a N7 since April to do the same in a VW Transporter, with a new dashboard, I can put pictures later.

Now I saw you used a webcam as rear cam. I want the same but to use like Russian Dashcams and record by some app.

Also need a cable that can connect the webcam and charger or can I use HUB?

Still have no supported webcam, so still do not know how to do this... If anyone can help or give ideas, I was thankful

Sorry for my english :p

[Nexus 7 General] PHiL_G4:
sorry for being absent so long

with tasker I disabled Wifi, BT, GPS, Auto-Sync and switch LCD off. But now I user Timurs USB-ROM with PowerManager and this works also quiet good!

No, my sound quality is fine. I use an external USB DAC, which works out of the box with timurs USB-ROM. The DAC is directly beside my amp with max 50cm Audio Cable. I had no noise issues so long!

You need an amplifier to wire your speakers

pls look into my 1st post.

there you will find a link to timurs kernel or USB-ROM (rootzwiki)

With this kernel or rom you can use a powered USB HUB or a y-cable with a step down power converter for example to charge the tablet and give power to usb devices at the same time!

If you want to connect a usb webcam directly, look for a UVC compatible webcam, there are many list about this.

My testet Webcams all had too small angles for dashcam functionality. I testet a Logitech C525 with auto focus.

Many N7 users have the EasyCAP 4channel USB capture card.

Once Timur compiled a working driver module but then removed in his rom because of users making stupidy with car cams...

regards, phil
[Nexus 7 General] JOAOOx3:
Thank you, Phil. I was using SmoothROM but already switched to USB-ROM. But I liked the TabletUI.

In USB-ROM, the locksreen is always portrait, dont know why :s Even being using the landscape mode, which should match the TabletUI.

Why did you use step-down power converter? What is the advantage?

Can you send me your wiring diagram? I was thinking to use only two chargers (12v to 5V 2.1A), one connected to the tablet and another connected to the HUB... Or just one charger if I dont need to use the HUB.

Am I wrong? Because I already bought them! ahah

I'll steal a Logitech C270 from a friend to test this idea, because I think this will not be possible to use that app to record webcam.

Also have here a USB EasyCAP that a friend gave me to record playing PS3, never tried to connect it to tablet.

It will work as a webcam?

did any other people have problems that the dvt fm adapter does not work on a usb hub?

I've tried two different ones, but neither are external powered ones, but I do use the Y power cable.

Also my reception is terrible

I have the cheep one from ebay
[Nexus 7 General] renealt:
ok a decent powered hub made the adaptor work, and setting the sdr to NFM, gain to max,

and replacing the lousy connector with some decent, and making an adaptor to use the stock car antenna did help,

but the high pitch noise is killing, I have to switch of the radio because I get a headache after 5 min,

and still the reception is poor, lots of static noise.

Do others have the same problem?

I have tried to install a reverse cam but its not working ....

I have all the stuff I need including the usb Rom Aug 17th version

The simple webcam app

Otg charge cable

Easycap

Now everything is being powered properly but when I open the simple webcam app it shows a blank screen ... Then when I click on camera it says no camera what do I need to do

From what I've already read I need and older version with a kernel module built in , so if anyone can confirm what version of the Rom they have this runnig off ?

My next thought is that I need a diff easy cap .... I heard specifically stk 1160 or somethig like that .....

Hopefully one of you can help me out ...
[Nexus 7 General] JOAOOx3:
Try open DE links and look for same at usa amazon or just google it.

If you cant find everything u need, try china websites (buyincoins, miniinthebox, ...) por eBay.

Google for "simplewebcam fork" and try it. If u cant download it, i'll send you later.

I have one Easycap that I use to record ps3 gameplay that wont work on n7, dont know if only need drivers or... so I bought a Microsoft HD-3000 and its perfect. Next step is try plug 2 webcam, one for rear cam and another to record in dash.
[Nexus 7 General] xdafoundingmember:
So that works for reverse cam
[Nexus 7 General] xdafoundingmember:
Your using the webcam as rear cam ?
[Nexus 7 General] JOAOOx3:
I'm testing this webcam for recording 720p to act like a dash board cam, till now i've tested dailyroads and autoguard app, all worked pretty fine.

Your idea its just to act like a rear cam, I think you just need to use simplewebcam app and a compatible webcam or you need to look for a uvc video grabber / easycap.

[Nexus 7 General] mixutuomi:
Thank you for all the great information on this subject!

I am working on a similar project. I have a Nexus 7 3G that I am going to be installing in the car. I have been testing Tasker and have been trying to figure out a way to turn the screen off and on automatically. I believe you guys are doing it with power? When USB charge is on, the screen is on and vice versa?

My problem is that I drive fairly short distances and it feels like it doesn't have enough time to charge if I do that. Maybe that 3,6A charger would change that, not sure.

So I thought I was smart and was going to do it with the brightness sensor. I would mount a small LED in the front of it and when ignition is on the LED would be on. Tasker works fine with it, except I can't find a way to turn on the screen? I ended up rooting the tablet and getting the secure settings plugin, but still can't make it work.

It turns off fine, but doesn't wake up the screen. Any help on this would be greatly appreciated.

I will design the bezel in CAD and have it 3D printed by Shapeways.com.
[Nexus 7 General] papinist:
you could use USB ROM (based on cyanogenmod) that has a setting for keep display active when tablet is powered. Didn't know if is a special setting of USB ROM or cyanogenmod.

With my old galaxy tab I used tasker, with very simple settings: if any power (usb or ac) set display timeout to 24 hours..

However, with USB ROM properly configured you will lose about 2% battery for a whole night so you have not to worry about it! You can also try better power source, like the DCDC-USB that many are using.
[Nexus 7 General] mixutuomi:
Thanks, I have ordered the 3,6A charger from Amazon and will install the USB ROM on the tablet.
[Nexus 7 General] JOAOOx3:
Glad to see one more nexus on roads :D

Your solution here is USB-ROM by Timur, like papinist said, 8 hours ago left car in the garage and now have 98% battery. So... I think this what you want/need.

I have programmed tasker to do all this, if you cant put tasker turning on the screen, you need to look over "programmer options" and there have something like "never turn screen off while charging".

But my doubt is, my n7 is working without that option so tasker is working fine...

My tasker is only about power, when turn IGN ON: keyguard off, airplane mode off, GPS on, start video dailyroads, launch NDrive, play music, WiFi on (for PPP Widget + 3G Huawei HSDPA), and keep display on USB.

IGN OFF: airplane mode on, pause music, stop video dailyroads + kill this app, lock screen, kill all apps (dont needed apps), stay on:never, go home page 1.

So, if u want to, i can post the xml file here for everyone use/try.
[Nexus 7 General] mixutuomi:
Thank you very much! This is probably a dummy question. But I managed to install 10.1- 20130817 USBROM Tilapia. It is working fine. Now where do I enter my google account information. There is no option to add google under accounts. Only corporate/email.

Do I have to install all the applications from individual .apk files? First time rooting and using a custom rom.

Thanks again!

[Nexus 7 General] JOAOOx3:

Nav and Music

I would love to do the same. Is there an app to run Google maps and Play Music side by side?
[Nexus 7 General] papinist:
play music can run in background and you can access it in the notification area
[Nexus 7 General] JOAOOx3:
like a splitt screen? i really dont know but i'll look for it. i use the navigation app full screen and music is in background. Sometimes when i dont need nav, i just use poweramp. Dont know dude, its all possible.
[Nexus 7 General] mixutuomi:
Success!!!! after a few failed attempts. Finally I managed to push the Gapps to Nexus and the keyboard wouldn't work. Luckily I didn't give up, a few re-installs of the whole USB ROM and Gapps and everything is running fine now.

What a great piece of work this is. Thank you to everybody who have been involved developing it!

My Audi A3 doesn't have a power line that is switched with the ignition so that is my next task to find. And then to draw up the 3D drawing of the bezel so I can have it printed.
