haha :D
[Nexus 7 General] cndctrdj:
Love it. This is my plan for my nexus7 as well. How is it working for you
[Nexus 7 General] PHiL_G4:
Hi!

I have ordered most of the parts yesterday.

The most difficult thing will be the mounting, though it is much easier than in other cars I think.

I dont know which usb dac to take. But at the beginning i am going to use the 3,5mm audio output.

I also have no idea which kernel is the best to use in car for fixed installation.

But this I will test when the cable arrives ;)

I will update the list then.

[Nexus 7 General] Letitride:
Interesting, indeed - love to see its progress. Do you plan to leave the N7 mounted in the dash or will you take it indoors with you (i.e. home, shopping & at work, etc.) because in America, it would become a target for break-ins ? Perhaps, not an issue or problem in Germany, per your signature details.

With the N7 mounted fairly low on the center console/dash opening, GPS receiver might not work that good - in picking up a solid signal, assuming that you plan to use Maps/Nav as many of the features are tied to running location-based apps.

I can imagine that in a year or two, that factory-adaptors and pre-fabricated/universal mounting kits will be available via Amazon for us to simply slide or drop our devices in the "slot" & remove it afterward, making it a truely mobile & portable device that will go everywhere - a combination of bluetooth & NFC. Wishful thinking or pipe dreams, perhaps - then, again - maybe not. ;)
[Nexus 7 General] PHiL_G4:
Hi!

No, I am planning a fixed install.

The device is behind the double din frame, only the display will be visible.

In Germany this a Problem, too.

But I think it is no higher risk than now with my Alpine Headunit.

I also thought about GPS problems because antenna is on the back.

Then I was looking for the antenna and considered to solder an external one or take an usb mouse etc.

But a few tests inside the building etc let me hope reflections and the little plastic around will be enough signal!?

I will post some screenshots from GPS Test Plus after install.

Same thing with power and volume buttons. First I want to solder ext. buttons.

Today I bought Tasker and played a little while with it.

I will switch to airplane mode on ignition off.

When ignition is on: airplane mode goes off and poweramp starts and play music.

For airplane mode tasker requires a plugin named Secure Settings (+Busybox +Helper Actions inside App) since 4.2.

If my Nexus is completely off, then it starts with the auto-power-on trick (see above) when usb power is connected. works fine!

Yes you are right, first mounting kits are available:

which usb otg cable are you using to charge the tablet. the one from ebay doesnt allow charging to the phone/tablet. and the one you linked on amazon doesnt seem to be able to charge. or is it using the regular usb to charge?
[Nexus 7 General] PHiL_G4:
AW: Nexus 7 car dash install + OTG charge + DVB-T + DAC + OBD + Webcam

you need a kernel from above which allow charging when otg cable is connected!

Yea thanks I know that part. But the cable from ebay states this "There is Micro USB female power connector, Can charge the extral USB device , like usb flash disk, usb hard disk.(cannot charge the phone)"

And the one you linked on amazon doesnt seem to charge?

hm okay, the ebay cable should work 100℅, see other threads from timurs kernel etc.

the one from amazon i will receive hopefully today (friday).

i will post the results of all ordered parts

[Nexus 7 General] yevgenydev:
How are you planning on handling the charging? For me my Wifi Nexus only charges in "USB" Mode - but from what I understand for the Nexus there is no diff between AV Charging and USB Charging modes.

Some of us on the NASIOC forums have installed a nexus 7 into our 08+ Imprezas. However the 12v to 5v 3a converter that we wired in for power doesn't charge as much as it could.

Many of us only see ~500ma charging under medium usage. I get as low as ~100ma charging when playing music and using GPS.

I would image you will have some interesting problems charging the device with so many usb connections running off the microusb slot.

Here is how it looks in my car, can't wait to see how well it looks in a Smart car.
[Nexus 7 General] bmakk2055:
Nice job

hi! looks very nice in your car! do you have some details?

i hope y-cable will arrive tomorrow, then a can test charging with timurs kernel with otg connectet.

btw: are data wires bridged in original asus 2A charger?

cant wait!

i didnt get it with the dvb-t stick and droidtv...

what a pitty :(

i am going to tell you tomorrow!

So your connecting it straight to your amp via those usb adaptors? Don't you need some sound mixing done via your deck?

I have a single deck and thinking I hook it up via Aux input or Bluetooth for audio and still use the deck for volume control as it would be too much hassle to control volume via the nexus.

And can the nexus handle more than one USB at a time? so it is possible to get a usb hub and charge while getting audio from it?
[Nexus 7 General] PHiL_G4:
Hi!

yes thats right. I have an usb hub 4port passive. Inter alia, i am going to have an usb dac which is directly connected to my Alpine Amp.

I dont have an usb dac right now because I dont know which one is the best to control Volume without a Headunit!

So it is indeed a quite interesting question!

The Headunit is no longer possible, because I want i fix installed Nexus7 in my "car".

And both is not possible at the same time in my Smart.

With the TIMUR Kernel (1st post) you can charge the Nexus7 an all connected devices simultaneously!

Nexus7 == OTG y-cable == --PSU; --USB hub (usb dac, dvbt, etc..).

If you dont need an extra dac you can use the 3,5mm audio output and a rca volume control like Shinare!

Have a look to his thread (bottom of my 1st post).

sorry for my bad english, its my school english only...

phil

//EDIT:

otg charge works!

see pics, 2nd post :)

Very nice thread.

I've been wanting to create a thread like this one myself... but just didn't find the time yet.

Keep it up! :good:

Edit: if you're keen on visualization effects while music is playing, you should try this app:

https://play.google.com/store/apps/details?id=com.cyphercove.audioglowfs

It's free and adds a nice effect to the N7. :)
[Nexus 7 General] cyberhern:
Are you running xposed? I had the same problem with xposed gravitybox. GB has a setting that stops the 'auto on with power on'. Just turn that setting off if you're running xposed
[Nexus 7 General] wanted66:
Thanks for your reply. I have exposed frame work installed.

Where do I find this setting please?

If this works I will be very very happy!

Thanks.
[Nexus 7 General] cyberhern:
Do you have gravity box?

Look for something that prevent it from turning the screen on.

If you don't have gravity box, start by unchecking modules one at a time, restarting the tablet, and powering on. If it doesn't power on re check that module and go to the next one. Repeat until you find the module. Then go through each and every setting in that module until you find one that prevents the screen from turning on on power up.
[Nexus 7 General] wanted66:
I don't have gravity box installed but after seeing your reply I installed it and went through all the settings but couldn't find any such settings which is preventing N7 from powering screen. Apart from GB I had Google search API but disables both and tested but still no luck. It works sometimes but most of the times it doesn't power on. Before rooting/flashing USB ROM I was running the setup with standard Android kitkat and power on off sequence was working perfectly (But battery lose was huge I had to get USB ROM) So i know its not the cable or adapter. Still I thought it was the power which was less than 1amp causing so bought a 2.1amp but no luck there either. Funny thing sometimes it works when the car ignition is on but most of the time it doesn't work. I tried swapping cables, adapters, Settings... arghhh Turning off the ignition and power off is always detected so thats working. Something is preventing the screen from turning on! I even tested tasker with different power sources (Instead of any, Tried USB etc) and they work sometime but most doesn't work.)

I just cant locate the problem !!!!!

Frankly this is the most frustrating thing ever.

I'm thinking about finding a another ROM.

Any recommendations? :(:(:(
[Nexus 7 General] cyberhern:
I will take a screenshot from another tablet to show you where to find it on gravity box. I also know cm 11 has a setting that will also not allow it to turn on when plugged in. I'll send you a screenshot of that as well so you know what you're looking for... verbiage. As to a ROM, I tried a variety of roms. Although several worked well, nothing worked as well as the OTA Kit Kat factory ROM. As far as GPS lock and smoothness. I did not want to lose custom ability of a ROM so I went with gravity box and several other xposed modules. What you're looking for is not at a ROM level. You need a killer kernel. I use Timur's ROM. It's not a ROM ignore the name. It's a kernel designed for in dash installs. Puts your tablet in airplane mode and a very doing sleep when power is off and immediately comes back to life 1 power is returned. It is absolutely amazing and exactly what that type of the install needs. When I turn my truck off at night the tablet is at 100 percent. And in the morning its at 98 percent. After a weekend off an activity maybe I'm at 96 percent. It is unbelievable. You may still have a way to fix this. The screen on when power on, is a basic function of Android and 1 that requires quite a bit too deactivate. You just need to find out what's keeping it from turning back on. Stay tuned I'll send you some screenshots

Thanks so much for taking your time on this!

First of all I have nexus 7 1st gen wifi only versiob.

Kernal version 3.1.10 Timur-USBhost

CM version 10.1 USBROM Grouper

Under developer options I have "Stay awake" option checked!

Per your 1st screenshot under settings I don't have the options like you mentioned. I just have the standard options under "Display" so can't find the settings you showed there.

Per your 2nd screenshot I have the Unplug turns on screen option. I have tried both checking this on and off (reboot as well) but no luck here either.

I don't have the tablet embedded into the car dash deep yet as I'm still at the experimentation stage. Right now I have the tablet hooked to a CD tray magnetic hook. I have ordered a OTG Y cable and waiting for the ebay delivery so haven't been able to get the fast charging working yet without it.

Under USB Host settings I have Fixed installation and Fast charging USB host options DISABLED.

I would love to get this working so when the car ignition is on the tablet wakes up or quick boots (Haven't tried the fast boot command yet maybe that will solve the problem?) I have the Android SDK + ADB so can enable this. Maybe that will help? :rolleyes:

Thanks again for your help. Its almost 2am here in Norway and my Mrs is not too happy me hugging the tablet. So I will continue this tomorrow morning :good: Thanks again for your help.

Maybe I can Re: Flash the ROM and Kernal?
[Nexus 7 General] cyberhern:
Got it the only other thing I can think of is for you to remove xposed. Reboot and see if power problem returns. If it doesn't... If the power problem continues, you're probably going to want to reflash and take the customizing step by step checking each time for power problem good luck
[Nexus 7 General] yayitspawn:
I have really simple questions I can't find the answers to...

I'm currently charging my N7 using a Micro USB cable straight to a cigarette charger. My battery seems to stay constant on use but doesn't increase. I'm using Timur's kernel on the 1st gen Nexus.

1) Is fast-charging only required for powering multiple slave devices, or will it charge my tablet faster?

2) I don't plan on using any DAC, flash drive, or any other USB slave. Is there any other reason to get a hub?

3) Do I need to switch to an OTG from my micro usb cable (is this the only way to enable FI mode?)
[Nexus 7 General] wanted66:
Hi, Picking up from last night, Today I completely removed Xposed and rebooted. Problem not solved. Then I completely wiped the tablet and went into recovery and flashed Timurs kernal and Gapps. Without any apps or anything the problem still exists. The power on is not detected while the device is sleeping. Its detected sometimes but most of the time it doesn't. Then I reflashed the device with Kangaroo Kernal. Same bloody problem! :eek::eek::eek::eek:

I think I'm going to give this N7 to my 3 year old son for destruction. hahaha

I just can't think of any other reason why this damn thing is happening!
[Nexus 7 General] cyberhern:
Don't give up just yet, try using the stock OTG ROM. I'm not familiar with the ROM you're using, but it has to be a setting in the ROM either pre cooked or something you're missing. after flashing stock rom add Timmers rom kernel. Make sure to answer the aroma questions properly Google each one if you have to. Then try the tablet. The stock OTA ROM will not have a turn on when powered override. Later you can add xposed. That worked for me. It should also work for you I hope.

I know you're frustrated, but this is a worthwhile project, you will love having done. I never thought I would enjoy the in dash install as much as I do. Good luck keep us posted

---------- Post added at 11:29 AM ---------- Previous post was at 11:23 AM ----------

Number 2 & 3, same answer. No need for an OTG cable if you're not going to install any USB device, ie thumb drive / back up camera... Run micro USB straight to tablet from power source. Fast charge is a good idea always in my opinion. Regardless of what your setup is.
[Nexus 7 General] wanted66:
Thanks for the encouragement man. Appreciate it.

I have Nexus 2012 Wifi version.

Android 4.2.2,

Kernal version 3.1.10-g25ab3af

Timur-USBHost-FI-2013-08-17

CyanogenMod Version 10.1-20130817-USBROM-Grouper

I have the Kernal zip file (Grouper version)

So If I'm following you right, I will use Nexus toolkit to unroot and restore the device back to original rom. After this process I will lock the bootloader, then root again, unlock bootloader, Install clockwork mod, then flash the kernal with timurs kernal. Then all should be fine?

I will try this and update you.
[Nexus 7 General] yayitspawn:
Thanks! I wasn't sure if fast charging would destroy my battery without an OTG.
[Nexus 7 General] yayitspawn:
I'm having this same problem now. It doesn't read the power on and the battery status will say Not Charging if I manually unlock the device. However, the battery life does increase so it is actually charging. For me the N7 will detect the power source if I turn the power off and back on but I don't want to do this every time. What's strange is that it will work sometimes on the first try. Let me know if you have any luck!
[Nexus 7 General] wanted66:
Exact same problem, Same symptoms. Like you said it sometimes detects power while sleeping. When the device sleeps if I connect the power it doesn't detect but if I wake the device while the power is plugged it still doesn't detect. So only way for me to get it working is to first manually wake the device and connect the power or unplug and plug the power again which is very inconvenient. I thought its something to do with my apps or mods so I did a clean install (Unroot, Stock rom etc) and then rooted, unlocked and installed a fresh USB ROM kernal and the problem still exists. I think this has something to do with the kernal itself. What version are you using? Since Timur no longer provide a download I googled and got this version: cm-10.1-20130817-USBROM-grouper.zip maybe there is a better version someone can share with us?

If I find a solution (Looks very unlikely now) I will let you know and please do the same :(
[Nexus 7 General] yayitspawn:
I'm using cm-10.1-20130817-USBROM-tilapia which should be the latest for the 2012 N7? I'm using the oem cable and wall mount which worries me that the problem lies with our tablets. Was the charging working with the stock/oem rom? Also will an OTG cable for Fixed Installation FI mode do anything for deep sleep/unlocking?
[Nexus 7 General] cyberhern:
I honestly think you guys have to revert back to a stock rom. CM may have disabled the screen on feature that is stock on all Android. Go back to Google stock. Then install the timbers ROM Kernel. Stop trying to use cyanogen. Everything you want to customize can be done later using xposed. I had a lot of problems with Paranoid Android and cyanogen. Ultimately I got the best results from the Google stock rom. Just go back to stock. If you don't know how to do that goto the appropriate Nexus 7 xda forms and find the appropriate files. I don't really know how more to clarify. I am stock Android and Timmers rom kernel. Everything works great
[Nexus 7 General] wanted66:
Much appreciate your help my friend. I have tried the way you suggested. Put the whole tablet back to stock. But my question is how do I just install Timurs kernal only. Where do I find the kernal file? I only have this file cm-10.1-20130817-USBROM-grouper.zip

So when I'm in stock. I root the tablet and then boot into recovery, use TWERP to flash the N7 with the file above. It's installing Cyanogen.

All I need is someone help me with a tutorial or guide to find the kernal file and how to flash only the kernal keeping the stock rom.

Thank you and sorry for being a total pain!
[Nexus 7 General] cyberhern:
That file is for cyanogen you need to stop using that zip file. Go back to stock. For instructions on reverting to stock find your model Nexus 7 in the Nexus 7 forums. After you need to buy a license for the Timbers ROM Kernal. From him and he will send you a download link matching your device and ROM. Follow this link http://mehrvarz.github.io/nexus-7-usbrom/ as you know, XDA does not allow blatant disregard for licensing. He deserves the credit he's done a great job with this kernel. Follow his link and he'll take care of you.
[Nexus 7 General] wanted66:
My charing works fine with wake up on Stock no problem there. As soon as I flash the ROM it stops working (Works sometimes) and I tried all the FI mode and fastboot thing and nothing helps. I think cyberhern is right saying something in the Cyanogen mod is blocking the screen from waking.

I have the same version except the grouper since i have a wifi version. I think the files we have are both ROMS and not Kernals.

I could be wrong but if you look at timurs page it says the USB ROM for 2012 nexus and TImurs Kernal for 2013 Nexus... Just makes me think..

---------- Post added at 12:41 AM ---------- Previous post was at 12:35 AM ----------

I guess I was right in thinking I'm using the wrong damn file.. haha :silly:

Don't mind paying for it cause its well worth it. But my question is for Nexus 7 2012 version he has no link in the donation to buy it from him. In download section it says "Download images have been offered until September 28. 2014"

I can actually see the donation button under 2013 version though.

Maybe ill send him and email and find out!

Thank you very much for your help.
[Nexus 7 General] wanted66:
Ok I managed to get the Timur Kernal for 2012 N7. (timur-usbhost-2013-01-29-jb42-fi.zip)

Now I flashed it and I can see the Kernal is set to Timur and running on Stock ROM.

The problem now is I dont see any of the options like before where I could set the FI mode, etc nothing.. I guess since I dont have USB ROM i dont see the settings.. My question is is the OTG fast charging is enabled since I got Timurs kernal and will I be able to keep the battery topped all the time? and In future can I run a Easycap to run a camera?

Btw this has SOLVED my screen wake up problem :good::good::good::good:
[Nexus 7 General] yayitspawn:
Let me know if this fix is permanent!
[Nexus 7 General] wanted66:
Unfortunately no. I still have the problem with Stock ROM and Timur Kernal.

I have decided to sell my N7 and get a 2013 version so will be working on it when I get it.

[Nexus 7 General] unrly:
I haven't been using my Nexus much in the car lately, but I'm hoping with the Lollipop upgrade, I'll get back in to it as I think I just need to tinker with it some more to get it right.

Has anyone used any other ROMs besides Timur's that work well with OTG? I see Timur has basically quit on the community, and I hightly doubt he'll be updating anything any time soon. Unfortunately, I haven't had the luck with other ROMs lately, and Timur's just worked right out of the box.
[Nexus 7 General] ryanjv:
autodroid looks promising. out of the box i didn't have much working, but i think if i spend some time with it, it could make a suitable replacement. i just haven't had a couple days in a row free where i can go without having my tablet in dash
[Nexus 7 General] unrly:
Thanks! I'm going to check it out now and keep an eye on it. For now, USB ROM is ok, but I feel it will become dated soon, unfortunately.
[Nexus 7 General] ryanjv:
it's dated but it does everything i need it to. The only thing i'd change which i really like on autodroid is a customizable nav bar where you can add and reorder any buttons you want. downside is no tablet ui layout so you lose some screen space

my display has gotten a bit stale but i could always make a new home screen to mix it up a bit

This is what i've had for the last year. I've got app lock on the right hand apps to reduce the distraction. I may go spend some time at the dealer to look at the layout of the newest mazda's and maybe try to mimic their arrangement
[Nexus 7 General] yayitspawn:
I recently switched over to an OTG Y cable so I can utilize Fixed Installation Mode and more importantly PowerEventManager from Timur's Rom. The deep sleep using PowerEventMgr seems to be more reliable for the unlocking/locking the screen on power so I didn't even need my Tasker profiles... So far so good.

I dont know how many people are still fighting the issue with the Timur's kernel recognizing power input and such but as I just got this rom onto my Nexus a couple weeks ago I will share what I found.

I was having the same issue with the sleep mode not working correctly. As soon as I got my OTG Y cable and plugged in my USB Flash drive, everything instantly began working as intended. Dont know if this will help any of you with this same issue back in October.
