I've simplified my set up. I'm using a regular hub as the only devices I have now is a DAC connected through a USB isolator, and a serial to USB cable for PodEmu.

Since I did that and the battery removal mod I'm not too concerned about how much current is going through the otg cable.

Side note. If anyone is using timur's, and there's really no reason not to be since it's now free, it still has a problem with chargers that have a LED.
[Nexus 7 (2013) General] SGH-i200:
Which USB Isolator model you are using?

[Nexus 7 (2013) General] pogs24ever:
Thanks for the quick response. Can you share the rom you are using ? or you just using a stock one?
[Nexus 7 (2013) General] fr4nk1yn:
Stock, severely manually debloated, and with Timur's kernel.
[Nexus 7 (2013) General] fr4nk1yn:
I play with installing Atmos every so often. Today was one of the times. Flash it at lunch it crashes whenever I change a setting. I took the tablet inside to check the connections on the boards, turned it on which launched my automation and I noticed Atmos appeared to be working. The EQ visualization worked and settings could be changed. I have no speakers on my tablet to actually test. Back in the car connected nto the DAC and it crashes again on setting changes.

I'm guessing it doesn't work with USB?

-edit: "Standard" problem. USB DACs have a bitrate higher than the EQ can handle. Audio.policy.conf has to be edited changing USB outputs from dynamic to 44100. Atmos now "works". The sound is ever so slightly flatter when disabled. No nasty artifacts like v4a though.
[Nexus 7 (2013) General] Gabsthejerk:
My setup is a FI of N7 2013 (wifi only) flo in my e46. I run a version of RRemix with Timur's kernel. Its not the greatest build, however i do have some issues with "mobile data network connectivity" as in it keeps the tablet awake and eats up most if the battery. My question to you guys: how can a wi-fi only tablet have mobile network how do i disable completely the telepony services?

What do you mean by "debloated" ? I'm guessing you're referring to Google's apps? Would microG be an alternative to stock gapps? If yes, how would i be able to remove stock gapps from the stock ROM?
[Nexus 7 (2013) General] fr4nk1yn:
I can't help on that. I've never tried flashing Timur's over anything but stock. If you want to go that route I'd find the closest to stock ROM then install the OpenGApps pico.

I thought of doing this for a bit but I gave up trying to find an older pure AOSP ROM.
[Nexus 7 (2013) General] Gabsthejerk:
The ROM i run is a RR 7.1.2 version with Timur's already built in.

Unfortunately it's been abandoned and it's a bit buggy, but with many tweaks and patches does the job well except for the telepony services (on a wifi only tablet!?) draining battery in suspend mode
[Nexus 7 (2013) General] FrenchSparda:
Sources are available for Timurs kernel, i dont understand why people are still complaining and are not trying to build their ROM with timur's kernel features. The latest (but dead) RR Rom with timur's features was really great, but such a battery drainer.

usb port is dead on my N7 2013, so i bought a Chuwi hi9 air for my car install. AOSP stock, rooted, i just need navigation (GMaps and Waze) listening music. So for 150€, that was a great deal.
[Nexus 7 (2013) General] pogs24ever:
Thanks to this thread! .. Installed mine..

What will be the best Audio software? . Currently I am using viper for audio quality through Bluetooth.. Any suggestions?
[Nexus 7 (2013) General] fr4nk1yn:
I know people love v4a but I find it gets in the way of the sound sometimes. I use Dolby Atmos. I also use a Fiio K1 DAC with PodEmu going to the cars iPod input.
[Nexus 7 (2013) General] pogs24ever:
Correct. I am hearing ups and down when I turned it on.. Can you share the link for dolby atmos?

My current setup.

Stock rom mm

[Nexus 7 (2013) General] fr4nk1yn:
I used the one from here: https://zackptg5.com/android.php#dolby It's been updated since.

*Remember if you use these mods, including v4a, with a DAC the audio_effects.conf needs to have USB bitrate changed to 44k.
[Nexus 7 (2013) General] fr4nk1yn:
Anyone using a reverse camera? I was using a EasyCap then a UVC and the engagement delay, combined with pausing music, made me stop using it.

I'm wondering if these are any better: https://www.aliexpress.com/item/201...-Radar-System-with-4-Sensors/1577019629.html?

eh, yeah. This would still need the easycap so it's a no-go.

[Nexus 7 (2013) General] valk791:
Hi guys I have a Nexus 2013 installed in the car. It has stock rom and Timur's kernel and Zuper Dac connected on OTG. I have basically 2 issue:

1) when I turn off the car the kernel put the tablet in deep slip, when I turn the car on the kernel wake up the tablet but Viper4Android doesn't work, unless I reboot the tablet;

2) the tablet is quite laggy I would like to speed it up, I set a performance kernel profile but I didn't see a big difference.

Can you pleade help me out?

Thank you in advance
[Nexus 7 (2013) General] SGH-i200:
Is this even possible? Why you don't restart the tablet in fastboot mode and set the correct mode?
[Nexus 7 (2013) General] Deeco7:
I not sure if that's possible either. The only reason I ask, is because my usb port is broken and I have no way of entering fastboot commands.
[Nexus 7 (2013) General] fr4nk1yn:
Just typed a long post and lost it. So short version: our tablets aren't going last for ever in an automotive environment. Backups are rare and expensive.

I stumbled across the Odroid while looking for a Pi to use as a NAS. There's Android images and it looks like this could easily be a replacement with any one of the available touchscreens between 3.2 and 10 inches.

This may have potential.
[Nexus 7 (2013) General] a8ksh4:
I'm late to the party here, but I've had a Nexus 7 2013 LTE tablet in my dash for about two weeks now. I moved the CD deck down behind the shifter and 3d printed a bezel to mount the tablet in a double-din opening. It looks pretty factory (well, the tablet does, not the cd deck).

The tablet setup is fairly simple... it's paired via bluetooth to the cd deck and I mostly use android auto on it, so the screen comes on when the cd player turns on. The tablet is always powered via the wireless charger, so I don't worry about low power mode or anything on the tablet. And, it's using the latest available Lineage 14.1 official build.

It's possible that a USB dac might give me better audio (the headphone port wan't particularly good), but I like using the bluetooth because of the convenient power-on, auto-unlock that works 40% of the time, and because the steering wheel controls for song skip get passed through to android via bluetooth.

i looked at the list of features and i don't see D2W though... so does that mean i have to set display to always on?
[Nexus 7 (2013) General] nhs510:
Allowing the screen to stay responsive would drain the battery. Not an option with firm sleep.

So yes, screen stays on while car is on.

Forum Closed

Since Timur's thread has been closed, should the discussion continue here? Perhaps the best thing would be for Timur to create a user forum on his site. I havent "donated" yet for the kernel so I dont know if there is a sponsor only forum. Is there a better place to discuss it?

No. Nothing is being sold here. Why are you causing trouble? How is your life affected by this thread staying open? These people are discussing installations. Plus, Timur has donated his USB Rom and Kernel for free since 2012, and that particular free Rom/Kernel could easily be included in this discussion.

I see the connection is made, but nothing requiring internet works. I can successfully tether from this phone to multiple other devices, but the 2013 Nexus is the only one that just does not work.

Here are some pictures roughing everything in.

Relocating vents to lower radio area and tablet to top.

Allot of epoxy, bondo, sanding, more sanding, then some more sanding, and painting to come.

This was one of the gripes I always had with my car is the radio is to low.... not any more

2004 VW Jetta... 2005 they moved it up and redesigned the interior :(

One question for you guys I really want to run a good quality external mic. Anyone have luck with anything ? And do you guys use google now allot im the car ?

Is it possible to change this in foxfi settings? Anyways I try bluetooth and it still doesn't work. And the fact that my phone tethers to other devices flawlessly says the settings are all fine on the phone. It's the tablet. Just can't figure it out.

What are you guys running for roms on your tablet ?

I have the timur kernel so I want to be on 4.4.2 but I would also like to be able to use the xposed framework to change dpi, font size and screen resolution between different apps. I think this will be extremely valuable for an in dash tablet. larger font for what ever apps you want gmail, Spotify ect... beyond that I don't really need anything else.

look here for a good explanation of the xposed framework and its functions:

Took a break from fabricating to do some wireing my dac and usb power adaper came in.

Did some direct soldering and added heavier power wire to my powered otg cable. Also ran power to the usb hub direct with heavier guage wire. And enclosed everythkng in a project box from radio shack.

Also for anyone who wants to change both ports on the power supply to "android fast charge" there is an easy way to do it.

And for our installations it does not matter which port you use because the power otg cable literally only has the power wires in it l. Its the kernel that enables the fast charging the different power powert on the charger only differ in the signal wire (d+, d-) wiring.
[Nexus 7 (2013) General] Nick8539:
I see many people keep asking how to turn the tablet on/off with the car and keep getting directed to use Timur's ROM. I'm sure there are many advantages to use that ROM, but it is not needed if all you want to do is turn the tablet on, when the car is on. And turn it OFF (not sleep, or deep sleep) when the car is off.

You need to be Rooted and unlocked bootloader for this to work. Then, you can do this by simply connecting your tablet to your computer and send this fastboot command "fastboot oem off-mode-charge 0".

That's all. This enables the Tablet to turn on automatically whenever it detects that it is charging. Basically whenever the Car turns on.

I then use Tasker to tell the Tablet to turn off whenever it is not charging. When the car shuts off.

My battery is always at 100% because it charges while in use, and turns completely off when your car is off. I've found this to be the easiest solution if you don't want or need all the extras that come with another custom ROM.

If you want to revert back to normal just send a new command and change it from mode-charge 0 to mode-charge 1.

I have my setup in this THREAD if you guys are interested.

Hope this helps.
[Nexus 7 (2013) General] flyboy1100:
Timur's isn't a ROM this time. Mine discharges minimally in deep sleep. No need for me to turn it on and off. Plus if I make a quick stop I don't want to have to wait for the tablet to reboot
[Nexus 7 (2013) General] papinist:
same here. When I start my car, I have music playing in about 4 or 5 seconds. Discharging in deep sleep with Timur's rom is about 1-2% overnight, maybe the same as if it is powered off completely ;)

Is there a new discussion thread somewhere for Timur's Kernel?
[Nexus 7 (2013) General] dmcgrath009:
Not that I am aware of.....

Todays progress got my factory VW monsoon amp to turn on with the Nexus.

Needed to put 5v-6v onto the negative front left speeker input to signal them amp to turn on.

Needed a ground loop isolator to prevent that voltage from back feeding into the DAC.

My first solution was what I found in some of the carputer threads for VWs on MP3car but I ended up with a skight buzz noise when not playing music.

I decided to try and tap off 5v from the usb puwer to the dac instead of the cheep radioshack regulator and that eliminated all of the buzz. 100% silent.

In the pictures the white wire is the 5v lime coming from the DAC to the amp.

One qestion for you guys, what are you using for local files as a media player and EQ ?

Also I have run into an issue with my tablet/rom/dac/??? I can't udjust the volume. Just on or off and the volume bar is kinda grayed out see picture below.
[Nexus 7 (2013) General] saf100792:
Idk what rom you're running or anything but i use that same DAC on AOSP and T1murs kernel and i can adjust volume fine. I use poweramp tho
[Nexus 7 (2013) General] dmcgrath009:
Ok mime is stock rom with timur kernel and xposed framework for a few things. Will try a reflash and if that doesnt work ill wipe it back to stock rooted and try again.

What rom are you running ? I was ppking around for somthjng on the correct base thag will work with timur
[Nexus 7 (2013) General] NNL:
I really appreciate your photos. I will be doing an install in a couple of weeks. I really want to have the ability to do an aux port. Can the DAC you are using play from both inputs at the same time?
[Nexus 7 (2013) General] dmcgrath009:
I have not tried both at the same time. I can test how it functions tonight and let you know. I assume you mean Nexus plugged into the dac not playing music and then the aux in on the dac plugged to your phone or somthing else playing music.

Next on my list is getting all the bezel fabrication done and then setting up tasker profiles to auto start wifi tethering on my phone. I atill have to root my note 3 ! Its wierd for me to not have a rooted phone ive been rooting everything I have owned since my HTC Hero years and years ago but I got this Samsung note 3 and its been fantastic no reason to root until now (wifi tether)

Proper OTG cable wiring?

Here's my test bench setup:

https://www.dropbox.com/s/v0lwsi8cfydzdmk/20140703_114328.jpg

On the left is my tablet dock, power is up top, and my usb hub on the right. Looking at this I'm looking for what the best way to power this when I move it to my car:

https://sites.google.com/site/sonic...9582/my-projects/otg-diagrams/Y_OTG_CABLE.png

The hub has an ac power cord available, I'm not currently using it - not sure if I would need it or not. I'll probably only be running the USB flash drive and USB DAC off of it. I wasn't quite clear if it would draw power from the 5v supply up top or not either.

I also have a 3amp, 15Watt DC-DC power supply that would probably help regulate power. http://www.opussolutions.com/product/170/DCL11__15W_.html

I could plug that the top usb connection into a breakboard like this, and attach it to the power supply.

https://www.sparkfun.com/products/12700

Or I could solder the power supply wires directly into the exposed circuit board attached to the dock. In that case I'm guessing I'd want just a straight micro-usb to female USB A cable for the HUB.

What's the best way to do this?

I wanted to go ahead and let people know, that if the main reason you want this kernel is to save battery than you do not need this. i am running official cm11 07/06/2014 with elementalx kernel 2.13 with a few build.prop tweaks and tasker profiles i was able to get 1-2% drop after 18hours. after waking it up and checking battery stats it showed i only lost 1% battery but from keeping the screen on going into setting to turn on screenshoting it did drop to that 2%. so yea it technically only dropped 1% over 18hours.

now i have my nexus 7 fiberglassed in my dash and have had it there for over a year with the nexus 7 1st gen and upgraded to the 2nd gen a few months back. these build.prop edits and tasker profiles make the battery much much better without having to purchase a kernel that should never be a pay for product in the first place. but this method has otg+charge working just fine and battery lasting ages.

if this is something people would be interested in let me know and i can either upload a CWM backup or try remembering all the changes i did to my build prob. this should be know i do not have anything other than my music player/tomtom nav/battery monitoring/tasker/ installed nothing else has been put on. but alot of unnecessary stuff was removed using root explorer in the system/apps directory including Bluetooth printing etc.
[Nexus 7 (2013) General] studley:
Didn't see it posted anywhere so thought I would register and post.

With my Nexus 7 LTE if it was plugged in to charge AND plug in to the sound system it produced a low buzzing noise through the car speakers when the device itself was NOT playing any sounds. (3 Things to note: the buzzing sound was tied to the engine RPM, and only started about 2 seconds after it stopped playing all intended sounds, and only if the tablet thought it was charging over AC (no buzz with USB mode).

I knew it was the tablet tried the usual, different cables, devices, even cars.

My solution: Keep it making a sound! For my situation I choose "Signal Generator" available from F-Droid, set it to 10 hz and -80 dbz, so nothing you could hear but my Nexus thought it was! The program also runs in the background, and seems to have no problem with other audio playing with it. Don't know about any battery hit as I only need it when plugged in.

Not the true fix I would have liked, but it's free and works.
[Nexus 7 (2013) General] Coronado is dead:
Sounds like you have a ground loop because the charged device is feeding back into the same system. Better grounding of the charging cable might help.
