I have recently purchased the original Samsung car holder.
After my tab reaches the 100% full charge, it beeps and advise me to disconnect.
If I don't do it, the tab itself begins to overheat after some minutes.
It oveheats really hi ! On the right side of the tab.
It seems like the car charger is not able to stop charging, differently from the house 220V charger.
Have you experienced something like me with your car charger ?
I have been using the car dock, sinds the beginning. Cannot say that i have noticed any excess heat. Note: i have used a brodit clip to install it on the air vent. Nicely in front of me without blocking line of sight.
All the phones i had "overheated" when connected in a car dock, having a forced air flow over it quickly eradicates this problem!
I use my tab in my car using the usb cable and a generic usb 12v adapter and it doesnt overheat, even when using the tab heavily (screen full bright, Torque app, and Pandora).

Ok, thanks for all your answers.
Could I ask you all, if you use bluetooth in your car?
I use bluetooth ON to stream music from SGT into my car stereo.
I mean it could be an overheat problem caused by the bluetooth antenna, isn't it ?

I never use bluetooth.

I have bought the original dock nearly one year agoand it overheated only one time (car standing in the sun). I use my tab with Bluetooth and wifi activated.
New experiment:
I have put it in the car dock, no wifi, no bluetooth. Only 3G + Google Navigator were ON.
It reaches 100% and after become very hot (in the right side)!
Now I need to try again with display off, and 3G off; only power charge.
And finally I will understand (as I suspect) there is something it's not ok in my car dock (I remember you that with my original home plug cord all is ok !)

Adding to my post earlier, and answering your question, my audio is through bluetooth while I am running those apps.
It's even two bluetooth connections... Pandora and Torque at the same time.

Yeah, i think you're right. Without being an expert: Sounds to me, like it doesn't deactivate after the battery has reached 100%. As I understand.d you, it becomes hot after it is loaded to full capacity, right?
You should try to exclude all functions, that may be the source of this malfunction. Put it into flight mode and just try loading the tab. Then start activating single functions like wifi etc. After that, you can try combinated function.s like Bluetooth and wifi.
i use an ebay dock for my phone when its charging, its nothing more than a holder really and the usb charger simply plugs into it which then plugs into the phone in landscape orientation.
i want to launch car mode every time i put the phone in the dock ie. when its charging. it would also be nice to kill the car app when i remove from charger.
how can i do this without tasker??
i tried tasker after reading all the good reviews, but it was pretty terrible in use, used more RAM than htc sense all the time when running in foreground, and after putting in charger, took 20-30 secs for the dock mode to come up.... it was also unable to kill the car mode, no idea why.
thanks
Try Liveware app from market (can't post link, too little posts)

I have built a Nexus 7 into my car and I have a small issue.
I need a tasker profile:
When I turn the car on, the screen turns on and music plays.
When i turn the car off, the music stops and the screen turns off. (along with other stuff)
I have created a "test" version of all this so when I connect a power cable (i.e when charging) it turns the screen on and plays music.
When I disconnect the USB (i.e. stops charging) the screen goes off, music stops, bluetooth off etc and all this works fine.
However, the USB will always be connected with power coming through so I cannot use this option. I need another way to detect if the car is on and when it turns off so I can run the correct tasks.
One option i thought of is buy a wireless charger and build it into the car. When my phone is placed on the charger, send a text message to the tablet to turn it on, and when i turn the car off the charging will stop, then the phone will send a text to the tablet to turn the screen off etc.
However after purchasing the wireless charger, i realised everytime i get a call or take my phone of the charger for whatever reason, the screen will go off and music will stop, so this isnt an option either.
So the question is, what can i do so tasker can detect that the car is on or off so the nexus can perform the tasks?
Hope that makes sense

You do realize that you really have two problems, right? The Nexus 7 will not know when the car is started, or stopped. Unless you can disconnect the power, manually etc.. If you can do that, you can send a command in fastboot to force the N7 to power up when power is connected, otherwise you'd have to boot it up manually.
You could unplug the USB charger.. Or have the tablet turn off after N hours of inactivity, although how do you detect "new" activity if there's no change when the car is started.
If your car has bluetooth, you could detect that as the "turn off" task perhaps, but turning on is probably your bigger issue.
Will the wireless charger idea work?

No idea what you mean by wireless charger (2012 model has no wireless charging), or how you'd control it with the phone. And unless your tablet is a 3g one, I don't know how you'd directly communicate with it either.
I just put my phone back to stock so I had to uninstall Tasker, however your tablet does not pull power once the car is off correct? I had a power based one as well, I remember testing it with a surge protector. I could leave the USB connected but flip the surge protector on and off (to mimic power to the phone being halted). To my knowledge when the car is off your USB shouldn't be drawing power therefore you could run the profile off that. Export the profile and post here. I'd like to help test it.

My last four cars (current and previous of wife and my cars) the lighter plug stays powered when the engine is off.
I think it's getting increasingly common for the plugs to stay powered. So there's no way for the tablet to know the car is off unless the car has bluetooth and you can look for that.

I have actually found the exact opposite to me true. My wife's 2014 Pilot goes off as well as my 2012 Veloster whereas my 2001 Sable and her 2007 Passat left them on. I'm not sure if you can resolve your issue then. I'll keep looking into it. You could trigger it based on speed I think

I suppose that could work.. Find out the speed for several periods in a row, if it's zero, assume it's time to shut down. But that'd mean it's playing music etc during that period etc.
IMO bluetooth, or a plug he can turn off, is really the only way if his USB is powered up all of the time.
Also remember, he has no way to know when to power UP either. I still maintain that's the bigger problem, especially if it's a fixed install and he can't poke the power button
At the moment, its connected so when the car turns on, the USB is powered up and when the car turns off, the power in the USB stops. So at the moment, my tasker profile works on "when charging" do Task A, when not charging do Task B. And it all works fine at the moment.
However I am having issues with charging, (The device is not charging fast enough when turned on and the battery drains over a couple of days) so i planned to keep it always charging, so the power in the USB will always be there regardless of if the car is on or off. So i cant use the "when charging" on tasker anymore. So i needed a new way to it to figure out when i got in the car.
Here are my ideas:
1. Have a wireless charger in my car for my phone. (Not the tablet). When i get in the car, i could put my phone on the charger, have the phone send a text to the tablet to turn it on. When i remove the phone from the charger, send a text to the tablet to turn it off. Simples
2. Connect a wifi router in the boot or something and have it start up only when the car starts, and turn off with the car. It doesn't have to be connected to the internet, it just needs to power up. Then i can do a 'When wifi near' on tasker to see if the car is off or on, and turn the screen off accordingly.
3. Connect the tablet to my phones bluetooth. Whenever i get in the car, they will connect and the tablet will power on. when i leave the car, it will power off. (Not the best option since it will stay on even if i am near the car)
4. Similar to option 1, but have a nfc sticker in the car. when i swipe my phone on it, it communicates with the tablet and turns it on, n then off when required. but i dont want to do this since i know i am going to forget to turn it off one day.
I don't really want to do the speed option, since i want it to turn on as soon as i enter the car, not when i start driving, and i want to be able to park up and use it when i need to put an addess in the sat nav etc.

If your charger isn't charging fast enough, you're using a crappy charger or one that isn't designed for Android. If your car has a built-in USB port, those are usually super slow, maybe 500mA, most less.
Anyway, glad to hear that your power follows the car state, that makes it all simple.

I've tried about 20 different chargers, up to 2.5amps. The problem isnt the charger. The problem is i dont drive the car long enough to give it time to charge. So if i drive the car for about half an hour a day, for the other 23.5 hours, its on standby. so the battery is always going to go less. So thats why I plan to connect the charger directly to the battery so it will always be charging.

Oh, I thought you had the tablet turning off when the car went off. If I were you, I'd set up a profile that turns off the tablet if it hasn't had power in a few hours, pretty simple to do. On Power, set a time var, every so often check that time var to see if it exceeds your threshold, and power down if so.
If you don't have much installed, it should be a fairly quick power-up, especially the plug goes hot when you start the car.
BTW I hope you're considering cold and heat if you're leaving the tablet in the car. Leaving it in the heat all summer will will the battery.
You can use Timur's kernel, it senses power to turn N7 on or deep sleep it.
Also charges N7 while using OTG.
It;s designed for car install.

I agree, you need to get at least a 2A charger for your car. My wife would watch Netflix on long drives and my car USB port or the normal USB charger I got for the cigarette lighter worked until I up'd it to a 2A charger. I can have screen on for hours while streaming video and still fully charge the tablet in a reasonable amount of time.
Has anyone figured out how to make the phone stay in dock mode when the wireless charging hits 100%? I am getting tired of my phone pulsating throughout the night as it turns off at 100% and turns back on at 98%. My clock app goes away when the charging turns off and lights up my room like daylight. I have tried using tasker and the magnetic field sensor, but that is not very reliable. I have tried other tasker profiles but can't seem to figure out a good mix of variables. I also tried using an NFC tag on the dock and the app Trigger to start the app, but that only works when I first put it on the charger. It doesn't have an Exit Task like Tasker does.
This is really annoying and a pretty crappy "feature". Anyone?

works great for me make sure you get this one:
Night Clock by

Can I ask why you suggest that one? I have a couple alarm apps that I could probably just open myself, but I'd like to be able to put my phone on the charger and have it open automatically and stay open until I take it off the charger. Does Night Clock have settings for this kind of situation?

a few reasons:
1: first it works with wireless charging on my nigntstand
2: turns off hard buttons
3: dims to my liking per settings
4: moves as a screensvaer
5 most important stays on after charger is full
I suppose a round-about way of solving this problem is to just use a wired charger, and save the wireless one for your desk or something, so that you don't have to worry about it acting up in the middle of the night. There's no terrific advantage to having wireless charging, IMO, so just be practical and use the wire.

I would do that if they made a dock for the Turbo. Unfortunately, Motorola doesn't put out docks for their phones like they used to. Now you have to buy a generic one that doesn't fit properly. I ended up creating a Tasker task that opens my clock app and doesn't allow it to close, so I have to close the app manually every morning but that's just being picky. It works pretty well, so I'm happy now.

I just set Tasker to launch my clock app (Dock Clock Plus) when it detects wireless charging. I tried to use the mag sensor, but I could never get consistent results. The Dock Clock Plus app has a setting to go to night mode automatically at certain times. So I have it set for night mode from 9pm to 8am. So if I dock my phone outside those times, it stays bright.
There's millions of these devices around. If not laying in a draw or closet, they're on craigslist or ebay half of a N7'13, (2013 model should be considered if purchasing).

Others/Tips/etc:
Put the tablet in bootloader and type this command into CMD/terminal.
This makes the tablet to boot when external power is turned on without physically pressing the button, even if the battery has completely discharged.
Code:
fastboot oem off-mode-charge 0
If using a Lollipop ROM and experiencing the NlpCollectorWakeLock here's a fix, you must be rooted:
Remove com.google.android.gms with titanium backup (or another utility),
Download the latest "230" version of Google Play Services from apkmirror.com,
Install,
Reboot.
Smooth Scroll Mod: Possible created a random reboot on the order of once 3 or 4 days.
It goes without saying, maybe, but do not install 3rd party widgets. Beautiful Widgets for example will cause thousnads of different wakelocks though a night. -inadvertently tested.
Attached is my V2 blocked list for Debloater. It removes more apps, but leaves a few others for better stability.
V2 now removes Connectivity Services and Play Services. I recommend using on a clean install immediately going into airplane mode so no apps will start auto-updating.
With Play Services being removed by the app you will need to install with adb if no file manager is installed beforehand.
Created a Tasker app that helps Power Event Manager. Secure Settings and Power Event Manger is needed.
If PEM doesn't shut down in 7 seconds, The app closes some problem apps, hope you used the debloat list, and calls PEM to sleep the tablet. Upon wake up app then disables airplane mode.
My current setup [Edited 09/18]:
Stock lollipop, from factory image, rooted, with Oxydo-Revamp kernel.
All apps not suitable for stand-alone tablet use have been removed. Debloat list is above in post #2.
Power Event Manager installed as system app.
Es File Explorer for file management, and ftp file transfer.
$3.50 OTG cable from Amazon. Charging seems severely hampered. Tablet and phone both occasionally discharge.
OTG is now handled by the 2nd cable listed in the OP with Amazon Basic USB extensions. Charging problems fixed.
Cheap USB 2.0 hub with independent power. Simple and impressive mod.
Torque Pro with a ELM327.
Tasker. To kill apps and use Power Event Manager to put the tablet to sleep.
Now using my Power Event Manager Helper app.
Behringer UCA202 to stock stereo AUX input: This is an incredible mod. Highly recommend over bluetooth.
Notes:
Torque can keep the phone awake if configured improperly.
Leaving ES File Explorer in FTP mode will also cause a partial wakelock.
Google Play Services, and Google App are causing wakeup triggers every 2-3 minutes.
Power Event Manager combined with Oxydo kernel is putting the tablet to sleep reliably.
Power Event Manager isn't terribly reliable. The Tasker profile is set to kill apps and call PEM for when PEM alone fails.
My awake time with stripped system and Tasker is consistently 0% over 24 hours. Longer periods show Tasker awake for 2s!
Settings:
I use Synapse and UKM TricksterMod for kernel management. Since battery life isn't a primary concern, my settings are to maximize the tablet's performance.
Turning the Nexus7 into a "terminal" is about the only hope it has to run Lollipop.
Tablet can run music, maps, and youtube flawlessly. Chrome appears to be the biggest problem app.
CPU Minimum frequency is set a 640MHZ 340MHZ,
Maximum 1624MHZ 1500MHZ,
Ondemand Governor.
Splitting the power to use two chargers is super simple when you figure it out.
Open the hub,
Remove the red wire from the PCB, and tape it off.
Connect a salvaged USB cable's red wire to the where the previous was,
Connect the new black wire to the PCB with the existing black wire.
Green and white wires on new cable are not used.
Whoa, mine if using stock lollipop is barely usable (too slow especially when multitask). Then I installed tiimut'r usbrom it's a lot bettrr (but then I needed the inmersive mode).
Current setup is slimrom (slimkat 4.4.4), all converted to all-f2fs. I dont need usb host stuff (yet), so far i'm satisfied with it. Use macrodroid for auto on/off stuff, automate as launcher, google maps for navigation, spotify/poweramp for music, and dash command for obd2 stuff.

I ran into the multitasking bit while setting up , everything last night.
With Torque and Headunit, running as it would in the car it's perfectly usable.
Open chrome, settings, es file explorer, and Ampere and it falls apart. Chrome is the biggest problem though.
How does Dash Command run for you? I've tried it, and seen many, that say the refresh rate is slow.

I had issues even opening up Google maps while in lollipop, soooo sllooooow. I only able to open maps, or music, or OBD stuff, cannot run them together. Now on kitkat I can run at least 2 apps simultaneously without any issues (like maps and music, or music and OBDII stuff). I did get issues when running three apps (music, maps, and obdII stuff). As for dashcommand, the refresh rates is quite ok for me. I like dashcommand morecompared to torque since it has nicer layout/themes out of the box. It's like having GTR multi information display that looks very factory.
I have another irritating issues though. If the nexus7 battery nearly full (above 90%) and charging. I hear a lot of strange noises, even when the engine is off. I touch the screen, doing any activities creates a lot of noises. if I disconnect the charger the noises are gone! and if the battery was like at 50% and charging no funny noises either. I was wondering how do I fix this.....
My setup is using the aux output of the nexus 7 to aux input of the factory bose head unit. Tried to use bluetooth to aux adapter but I did not like the sound quality (too many hissing noise) and also introduces alternator whine
Should I get the USB DAC thing?

I have another irritating issues though. If the nexus7 battery nearly full (above 90%) and charging. I hear a lot of strange noises, even when the engine is off. I touch the screen, doing any activities creates a lot of noises. if I disconnect the charger the noises are gone! and if the battery was like at 50% and charging no funny noises either. I was wondering how do I fix this.....
My setup is using the aux output of the nexus 7 to aux input of the factory bose head unit. Tried to use bluetooth to aux adapter but I did not like the sound quality (too many hissing noise) and also introduces alternator whine
Should I get the USB DAC thing?

I'm sure lollipop is working so well because of everything I stripped out of it. I'm about to strip some more. Was working on gauges for torque. I'll give Dash Command another try though. It does look much better.
I'm still getting my cables added to my cart but you need one of these for noise:

Are you using a stripped down stock ROM or you manually disabled everything?

I just bought one of these.. (not exactly that brand), on mine one of the channels is not working so I only got one side audio channel only It also degrades the sound quality I think. I guess I need to bought the better one.
EDIT: What if I buy the ground loop isolator intended for 12volt line like this one? Install it on 12v cigarette lighter (before 12v to 5v dc-dc adapter). If this one works the audio quality will not changed as the ground is lifted on the 12v line.

Yes, A manually stripped/blocked stock ROM.

Hopefully the one I ordered works. It has a decibal increase to make up for that degradation from the transformers.

I ended up ordering one of these . Let's see how it goes few days from now when the package arrives (and time to install it)
Counting on PEM to sleep the tablet might not be the best idea. It only seems to actually do it IF the tablet is charging in OTG mode.
Tablet went dead in the car during a test possibly because the OTG cable, or another cable, is malfunctioning.
Might have to go Tasker although I've never gotten it to work properly for anything, and I've never accepted it won't demolish battery polling every few seconds.
Damn. Whatever happened to my tablet it appears to be dead. Won't power on, won't reboot. May be a short lived experiment.
I've ordered hundred of dollars worth of parts for the car so If it doesn't charge by Wednesday i'll have to buy a N7'13 off CL.

I use Macrodroid to manage sleep/wake up on mine. Very simple app and easy to understand.

That's too bad maybe try to plug in to your pc and recognize adb or fastboot or something?

I going to try it out. I'm quite used to Trigger, I haven't used it in awhile though and not for this type of power control.

Took it apart after not charging at all. Checked battery voltage, then voltage at the microUSB, tried powering it on, yet again, and it did. I did nothing different, same cable and charger. Wiggling and poking the socket it doesn't appear to have a loose connection.
My new OTG cable is on the proverbial slow boat so I can't eliminate that until early October!

Care to give your macros for power? It's time to try other methods of forcing the tablet to sleep.
Tasker, as usual, is impossible.

My macro is pretty simple, I just set on charger connect, screen on, run app A,B,C Then another macro on charger disconnect, screen off, close app ABC (killing navigation apps, music, OBD stuff). You can apply also turn on/off airplane mode, turn/off mobile data, wifi AP, etc but I decided to keep them on even when not charging to track the location of my car in case my car got stolen lol. Another macro that I occasionally use is, turning off the tablet when the charger is disconnected (key ACC off). No need another macro since the tablet will auto power on when charger is connected (key ACC on).
Before macrodroid I was using condi, and it was not always working.
@tesna Thanks. While playing with Tasker I found it doesn't actually cause deep sleep, just shuts down radios.
We really need a kernel with some of the newer improvements. And firm sleep.
Since my car isn't a daily driver and only goes out for relatively short trips the tablet will eventually go completely dead.
@fr4nkl1yn, there's simpler solution to that problem. Just set in tasker/macrodroid to turn off the tablet once the ignition key is on the off position (charger disconnected). Bam no battery drain issue...

yeah, I'm going to have to do it. close apps and set airplane mode with screen off at power, and a timer to shut down after a few hours. Off_charge_mode will take care of the rest with screen, radios on at power on.
Having an add issue. the tablet is powering the charger, and the key circuit of the car, through the otg cable.
Further research shows its functioning just as it's supposed too. This is also the cause of the issues I was contributing to pem.
When the power is shut off while a otg device is connected, or the tablet thinks is connected, it doesn't sleep and powers the otg device, my charger, from the tablet. At that point it doesn't recognize any change in external power until its physically unplugged and reconnected.

This leads me to believe pem isn't switching the fixed install trigger, or oxydo-revamp has a bug.
