Sadly that didn't work for me. The pay app just crashes when I connect the camera. I tried every different variant of settings that I could find. I tried 2 different easycap devices and 2 different cameras as well. I tried many free camera apps but they all just said disconnected. I was able to see the device in the USB list in Timurs area. Unless someone has a magical idea, I think I'm giving up on this one. Too much money and time spent. :(

So, for a not-so-tech person, who wants a nexus 7 2013 in his car to run BtSsm via a Tactrix open port 2.0 and Tactrix OBD2 extension cable, a reversing camera, Google maps for navigation ( downloaded area maps as not running a sim card or tethering to phone ), and maybe some music from the Nexus through the car stereo ( Macintosh ) would you recommend Timor's kernel or Tasker? or something else?

So far I've got a Behringer UCA222 USB DAC, a USB OTG Y cable, a 12v to 5v 3A 15W power supply. Waiting for Tactrix bits. Rooted my Nexus 7 today, so now it's ROM time, but which one??

I have problem with my nexus configuration. Everything works fine first time if i connect hub and dac to tablet but when everything is connected and i turn ignition off and on tablet do not see HUB, DAC. Works pulling microusb from tablet and putting it back in. Is there any solution for this?

Hi guys what do you use Tasker for? I would like to implement some tricks busy I don't have so much imagination :D

One familiar advice for this familiar problem is to ensure that your hub, dac and other peripherals receive power first before your tab. Not sure what your power setup is, but at the least you could include couple of switches in the power circuitry and switch them on in the correct order. That's how I have mine setup.

Anything that will cut down your fiddling with the tab while driving and let's you focus on the road instead. I have nearly 40 different profiles in place for my setup. Make note of the distractions the tab usage causes and all of them are potential candidates for automation
[Nexus 7 (2013) General] goliat88:
My setup is Tablet connected to OTG+Charge Power goes in to this cable. Hub is connected to OTG Cable. Sound Card is connected to HUB.

Can u tell me how your setup looks like. Mayby tasker can delay powering tablet?
[Nexus 7 (2013) General] valk791:
40 profiles are a lot! Can you give some examples?

I've thought a profile to automatically connect phone and tablet with BT Tethering using autoremote but it doesn't work [emoji14]

I have a profile that through autoremote send the parking location to the phone.

I would like to have a profile that stop the music when I receive calls on my phone. It's could be amazing to have phone audio on car speakers.

My tablet finally works like i want it to work by installing timur's package - its free now but facing next problem. Ive connected PCM2704 DAC and Yatour by minijack but volume of that is very low. Is there a way to boost volume on android or i have to use some kind of amplifier?

I need guide here. I just want to add a wireless charger to my nexus 7 car install. I have a Nokia wireless charger that woks well with the nexus but only came with a wall adapter rated 12v, 0.75A. How do I use the charging pad in the car with the cigarette port since the cigarette port outputs 12v, 10A. How do I step down the high current from the cigarette port.
[Nexus 7 (2013) General] nunclud:
Update, I connected the cigarette charge directly to the charging pad with a 2A fuse on the positive line. It's working perfectly, am still observing it for any irregularities. :good:

Not exactly the case, you CAN get and receive calls from a tablet

If you install hangouts dialer you can receive/make calls & text messages as well as hangouts messages and video calls. If you want to have this work with your existing cell number you can just setup a google voice number so that your mobile number forwards to it after so many rings. I just give out my google number so that I can switch cell providers while keeping the same number all the time (also free international calls).

Or use Verizon Messages app on the N7 if you have Verizon as a phone carrier and HD calling enabled on your account (free).

I'm having a GPS problem. I switched from a LL Flo to a MM Deb, both using Timur's kernel.

I Found the screen on the Craigslist sourced Deb had a hairline crack that caused it to be unresponsive in one corner, so I was forced installed the Deb boards in the Flo's screen. No, it's not a perfect fit, or even just a fit.

The GPS antennae on the Deb is in the battery cover, which couldn't be reinstalled. I cut the entire antenna area from the cover, soldered wires to it and the board, then mounted the antennae under the tablet bezel horizontal to the sky. I also "shielded" the cable with aluminum foil grounded to the tablet's chassis.

I've gone from connecting to 3 satellites to solidly connecting to 13-16, but it still randomly loses the lock or just refuses to lock at all. I'm monitoring with GPS Status and Toolbox. My Pixel 2 XL sitting next to the tablet gets, and keeps, a lock with as low as 4 satellites.

Any ideas? I'm thinking it's software since it's connected to more satellites than it should need but still doesn't get a lock.

---------- Post added at 08:41 PM ---------- Previous post was at 08:33 PM ----------

Easycap is a bastard on Timur's. i use a text editor to add the lines to /data/local/userinit.sh :

insmod /system/lib/modules/saa7115.ko
insmod /system/lib/modules/stk1160.ko

Cases are sensitive, and make sure there's no line after the last.

In terminal emulator type lsmod after rebooting and you should see both saa7115, and saa1160 returned.

You ever get this sorted out? This have been driving me crazy for months. I have 2 chargers installed and just switch between when one stops charging. I'm thinking of just doing the battery delete mod.
[Nexus 7 (2013) General] Deeco7:
I've recently done a car dash install, but got some caveats.

I woke up one morning and my car wouldn't start due to the N7 draining the battery I presume, I've only got positive live on my car so the cigarette lighter is always running even when ignition is off and key is out.

I was wondering if it is possible to make the N7 stop charging when it hits 100% and when it falls at a set threshold it starts charging again or stops charging at a lower voltage.

Also, as my install is integrated, I need a way of accessing the power button in emergencies, such when the battery completely dies, which has happened.

Are there any apps/Tasker automation that automatically turns on the tablet upon shutdown?

The power source is currently via wireless charging as my port is broken.

I want to be able to achieve this using my current setup using CM 14 and Elementalx with root.

Any help would be greatly appreciated, thank you!
[Nexus 7 (2013) General] fr4nk1yn:
[MENTION=2740445]Deeco7[/MENTION] I don't think the problem is the tablet. The charger will draw power all times. At 100% the tablet will stop charging until it falls below 96%(?).

interesting: I just did some math and 1.5 amps could kill the "average" car battery in 3 days.

Since the charger is running at all times I'd look into switching it.

There's a magisk module for stopping and resuming charging at certain levels, not sure if it will help you at all:

Hi,

Hi,

I just finished with setting up N7 2012 in my Opel Meriva. I know that it's not the same as Astra, but I'm willing to answer any questions about my setup .

Regards.
[Nexus 7 (2013) General] Deeco7:
Great! Would be great if you could share how you managed to keep tablet charging with the permanent live and not kill they battery.

Thanks
[Nexus 7 (2013) General] petarl:
I did the no battery mod by kevdav. It works great. Found cheap LM2596 dc-dc converters at aliexpress and used one to convert 12V from car battery to a bit below 4V (I can't remember exact value, but Nexus thinks that its 70% charged). I read that 5V is not recommended over at timur kernel subreddit and at kevdavs' forum. LM2596 is connected to permanent power supply and tablets' usb port is connected to ign line so that timur's kernel wakes tablet when I start the car and goes to sleep when I turn it off. I'll post full schematic in a few days.
[Nexus 7 (2013) General] fr4nk1yn:
I'm not sure what happened but mine was not accepting the command. It should reboot after it's successful. After many tries it finally rebooted after the command an has worked since.

Interesting. I thought they were using a usb charger for the battery mod. I'm about to do this since mine refuses to charge no matter what. I'll set my adjustable voltage for 4.4v which should be 100%. I don't want the tablet to attempt to charge the "battery".

edit: Tried the battery removal with a 5v adapter and it stays on the google screen.
[Nexus 7 (2013) General] petarl:
I think that 4.4V is too much. Try it with max 4.2V. Hint: check the N7 battery voltage when it's charged 100%. I've attached the image of the battery with marked voltages - I can't read chinese but I believe that those on the right side are max values.

I've set output of mine DC-DC to lower than 4.2V (and higher than 3.75V) because I don't trust that car battery will provide the correct input for DC-DC converter to lower it to exactly 4.2V. And the charging module probably always kicks in when the battery level isn't 100%.

To test it all on desk, I've used PC PSU. It has 12V line (yellow wire) which is perfect for testing this setup.
[Nexus 7 (2013) General] fr4nk1yn:
Used my adjustable drok and set it at 3.9v, I wouldn't boot. I' using a cheap wallwart rated at .8amp though.

With the charge cable in and the "battery voltage" adjusted to 4.2 it booted! Said batter was at 93%. Adjusted it to 4.4v at the batter connector and it's now at 91% but It's not showing a discharge or charge, not sure where it'll go after a reboot, I have an idea it doesn't like fast "battery voltage" swings. Battery voltage on device is showing at 4.361v. The battery voltage shouldn't matter as any good regulator should compensate.

Odd thing is this tablet was about to be scrapped it was so bad. It's acting quite zippy for the moment.

Tablet Drain while using GPS

Hello... I've done my best to search around... I think my question is too specific.

I have a BMW E92 M3 (2008)... I have a Nexus 7 (2013) with Timur's Kernel installed (v4.0).

Charger: I have a 12V to 5V DC converter running from the cigarette lighter wires to my nexus 7. Here is what I'm using: https://www.amazon.com/gp/product/B071XLLKNF

This charger has a output capacity of 2.5A (3A max). Which should be enough to power the tablet. I've also removed the USB connector on this, and soldered a USB cable (the red and black wires are thick enough, length of the USB is about 3 feet) so that I can plug it to my OTG adapter on the tablet. That way, the tablet can go into "deep sleep" mode.

PROBLEM:

If, I run the tablet at full brightness, and just play music, it's fine... It will hold a charge and slowly climb up in percentage. But, if I'm running GPS (Waze) it will drain the battery about 1% every 15 minutes or so.

I've made sure to turn on fast charging in the application properties that comes with the ROM.

This is a problem for me, because I use Waze constantly. And every now and then I find myself not being able to use it.

So, is there any way to see that the table is using "Fast charging"? Do I need another charger?

Thanks :)
[Nexus 7 (2013) General] Buratei:
For those of you still with ground loop problems on a USB dac, head over to ebay/aliexpress and run a search for a "usb isolator". should pull up something in the $10-$12 range. I used one of these on mine and that really removed all alternator whine immediately.

I've got a few questions myself.

1) What is a good ccd/cmos cam for a back-up camera under $20 these days?

2) I've been trying my hand at getting a decent fm reception out of my rtl2832u dongle. The included tiny mcx antenna doesn't work at all, the motorola-terminated whip antenna sorta works but still piss poor. How is everyone getting good reception from their cars? My windows are tinted, surely that doesn't help matters much when it comes to in-cabin options.

3) I am running a flo in my main car, a grouper in my secondary. Of the two, the latter is having a somewhat trivial issue of not registering power down all the time. Thankfully it does wake from sleep on resumed power without a fail, but recognizes power loss like 1/3 of the time only. It is being fed from a delayed-off relay originally meant for a dashcam; I installed that to safeguard against rapid on/off fluctuations confusing the PEM (this happens time to time if you drive a stick). WIthout the said relay, restarting the engine did some bizarre things like sleep-looping or going into sleep on resumed power (!) The relay fixed most of that as expected, so this is one lingering issue I am trying to sort out. It could be that the version of PEM I am using isn't fully compatible with los 14.1 the grouper is running.
[Nexus 7 (2013) General] nickmv:
Nope -- it's literally a hardware design flaw --- the tablet is capable of drawing more power than the internal circuity is set up to provide, so you literally will drain it while plugged in. I know, crazy right?
[Nexus 7 (2013) General] fr4nk1yn:
Crazy indeed. I learned the hard way the tablet needs at least 1.8amps just to run reliably. And that's before music, GPS, or anything else you might want in a car infotainment system.

Hey all, I'm trying to get into this with something relatively simple - just gps and music. My biggest obstacle is battery between uses. My options are:

Turn it off after every use. It takes ~60 seconds to boot. Are there any roms that specialize in booting quickly?

Reducing idle battery drain. Are there any roms that specialize in sleep/minimizing idle battery drain?

My battery has totally died and is not recharging anymore. I guess it has lived out it's natural life. What should I do now? Change battery or get a new tablet?
[Nexus 7 (2013) General] nunclud:
Your best bet is timur's kernel with stock rom if you are doing fix install, else you have less options. By the way,m what rom are you using. I normally use macrodroid to put tab to sleep/hing power savings mode when not charging. I didnt do lifed install, i charge mine in the car with wireless charger and can easily take it out when i want because temperature sometimes can be so high up to 35 - 40 deg and thats not good for the tab in the car.

---------- Post added at 04:33 PM ---------- Previous post was at 04:25 PM ----------

try rotation control https://play.google.com/store/apps/details?id=org.crape.rotationcontrol. Force tab to be in a given orientation. Mind you, It might cut off some edges

[Nexus 7 (2013) General] fr4nk1yn:
My suggestion for both of you is Timur's kernel, it's now free with no support, and do the battery removal mod. The trick to the battery removal is to use a large enough power supply and large enough cables. I'm incredibly impressed how great my install has become not worrying about battery and random crashes.
[Nexus 7 (2013) General] Evo3dUser:
Thanks for your reply. I already have Timur's kernel. What do you mean by large power supply and large cables?
[Nexus 7 (2013) General] fr4nk1yn:
I had to kind of muddle my way through the battery removal mod.

Short version. I couldn't keep my battery charged so I did the removal mod. After a couple weeks it became so unstable I thought the EMCC was faulty. As a last ditch effort since I couldn't find another LTE model for sale anywhere I changed the USB cables I originally did the mod with to the type of wires on a power supply. I then had to plug it into a 1.8 amp charger just to boot. In the car I use an adjustable 3 amp supply set to 4.4v and I'm totally thrilled with it now! Battery stays at 100% and haven't had a random reboot since I've fixed it.
[Nexus 7 (2013) General] naiku:
What do any of you plan on moving onto when your Nexus eventually dies? I have had mine in the car for 5+ years now and it is starting to slow down, understandable, it's been rock solid and I am sure was not designed for the environment it was kept in!! But, trying to find a replacement is proving difficult, Timur's kernel made running the Nexus a piece of cake.

I have a Galaxy Note 10.1 2014 that I looked into trying to use, but I don't believe USB Host Mode works on it. I know it is also a few years old, but is barely used, runs a much newer version of Android that my Nexus (mine is a 2012) and the display would be awesome in the car. But, that USB host mode is a deal breaker. I can use Tasker / Secure Settings etc to put it to sleep, but not being able to use a USB hub, Joycon etc. puts a stop to even trying to modify my dash to fit it.

Any suggestions on newer tablets? Or should I start stocking up on good condition used 2013 Nexus 7's?!

[MENTION=1118153]fr4nk1yn[/MENTION] sadly I think you are right, I was really hoping the Samsung tablet I have here would work but it does not appear that it does. I tried looking it up here http://usbhost.chainfire.eu/ but the site is not working. I will say though that the USB port on the Samsung I have needs to be replaced, so maybe that will get it working, but I am not holding out much hope. The Samsung forum on here has no mention of USB host mode at all, I think we are a pretty small group who want to install tablets in their vehicle!

I really don't want to go to an aftermarket head unit due to the limitations, whether it be the ability to play pretty much any format, or simply change the interface to something I like, it's not readily available.

Off to eBay to look up N7 prices and a new USB port for my Galaxy Note.

On a different subject, any recommended USB hubs? I currently have this one: https://www.amazon.com/dp/B0012JE3YM?tag=vs-tech-convert-amazon-20 What I like about it is that the barrel connector on the back has a USB on the other end, so it plugs in nicely to my DCDC-USB. However, both that connector and the USB-B have become very loose over time. Looking to replace it with something similar that I can plug easily into the DCDC-USB for power.

Anyone running a 128GB flash drive? I have a 64GB that got full and was annoying having to constantly delete music to replace it with something else, I picked up a 128GB but for some reason my USB hub is not providing enough power to the flash drive for it to be recognized. This has been the case with 2 different USB hubs, the first it would recognize it after a length of time, but cut in and out. The second hub it does not even load the flash drive.

The hubs are powered via a DCDC-USB. But, I want to check my connection on that since an FM dongle is also failing to be recognized since installing the new hub.

Hi Guys,

I'm using Nexus 7 (2013) in my car for more than a year. I have 2x DC-DC power source, no battery mod, USB OTG hub and WiFi OBD2 dongle (connected from time to time).

Now I would like to upgrade audio with Bluetooth DSP and amplifier.

I would like to know if you still on Timur's Kernel or moved to something newer?

I was thinking about LineageOS but I'm not sure if it is as good for a car as Timur's.

My problems are:

- overheating protection - summer is coming. In high temperatures my device reboots when sleep. Have you successfully removed temperature sensor?

- device does not go sleep - it happens after 2-3 weeks of using a car. It does not go sleep. I have to unplug USB and connect again to make it work for next weeks.

- loosing GPS - very rare but happens. No satelite visible, reboot helps.
