I haven't had an issue locking on GPS fairly quickly with mine. Are you connected to a Wi-Fi or 3G signal? That certainly helps. Maybe try the app called "GPS Status & Toolbox" to see what's going on with your signal
[Nexus 7 General] gregthomas129:
Have you had the back off? I had the same problem and it ended up being the little spring clips that connect the GPS circuit to the antenna embedded in the back cover. I had the back off and it stopped working after that. I took the cover back off and bent the little spring clip contacts up a little and this fixed the problem. Mine is buried deep too but it works perfect now.
[Nexus 7 General] Captain Sweatpants:
You could take the GPS antenna off the back of the case and mount it where it will get a signal and use shielded cable to reconnect it.

[Nexus 7 General] N!KE26:
Yes I had the back off and took it away again and bent the clips but still the navigator shows wrong road:) not good to navigate with. I think I have to move the antenna from the backcover:rolleyes:

Edit. What cabel should I use between the nexus motherboard and the antenna?
[Nexus 7 General] Captain Sweatpants:
Coaxial cable
[Nexus 7 General] N!KE26:
Which of the connection pins are for the gps antenna, I cant find in google:(
[Nexus 7 General] Captain Sweatpants:
If you look at the back and be of the circuits is marked GPS ant line it up with the motherboard and see wilhich pins connect to it. It's the top left i think

Today I will take the nexus out off the car and try to move the gps. At the same time I would like to change so that if the battery runs out the tablet will auto boot when connected to charger. I have been looking step by step guide but cant find, so could anyone write a step by step guide to change: fastboot oem off-mode-charge 1 to fastboot oem off-mode-charge 0? Im noob in android:o
[Nexus 7 General] GrandeParade:
Do you run Kangaroo-kernel? Then use PowerEventMgr app to set fast-charge, fixed install mode, firm sleep etc..
[Nexus 7 General] N!KE26:
No, I have CM11 stock kernel
[Nexus 7 General] GrandeParade:
Well, if you want it to sleep and wake-up based on power status, and you want to run anything newer than 4.3, you need to run the Kangaroo-kernel. It's called Fixed Install Mode.
[Nexus 7 General] N!KE26:
I have tasker to wake, sleep, airplane mode on/off and wifi on/off

Edit. Do you recommend Kangaroo-kernel and what rom then? works with CM11?
[Nexus 7 General] GrandeParade:
How do you wake it up when power returns?
[Nexus 7 General] N!KE26:
In CM11 settings->Display & Lights -> check: wake on plug

Edit. Then also Settings->Development settings->Stay on when charger connected
[Nexus 7 General] gregthomas129:
You need this: http://www.wugfresh.com/nrt/

In advanced utilities is a place to run fastboot commands.

I did try this and it wouldnt work with a normal OBDII that works with ELM type interface. you need to buy a OpenXC certified device for this
[Nexus 7 General] Peetje GTI:
Hey Phil. There's something i don't understand regarding tour setup. You are using a Delock OTG cable attached to a normal y cable. Shouldn't that be an otg cable too? Also, from that y cable it goes tot yor USB hub, from what i can see had a male USB input. Your y cable had a male output. Did you use a converter for that?

I'm currently usibg a cheap otg y cable wich (i think) is giving me soms static and engine noise issues. Would like to copy your setup. Thanks in advance mate.
[Nexus 7 General] motoridersd:
Are you using a USB DAC for your audio or the Nexus 7's audio jack? Engine noise is caused by a ground loop. Static is caused by a bad connection in a 3.5 mm jack or elsewhere in your audio path. How are you getting the audio to your headunit/speakers?

You need a ground loop isolator to get rid of engine hum, and a better/solid connection to get rid of static. If the static is due to interference, then this is an analog problem somewhere along the path from the audio output to the input, through the headunit, amp, and speakers.

DAC and SDR issue

Has anyone else had a problem using a DAC along with an SDR. I'm using a NuForce Icon uDAC-2 along with a NooElec NESDR Mini USB RTL2832U & R820T Tuner with SDR Touch. Both devices work fine separately, but when they are both connected to my Car Install setup, SDR Touch can't find the SDR unless I unplug the DAC. Any thoughts?
[Nexus 7 General] motoridersd:
Are you using a powered USB hub? If not, your problem is probably that the DAC and the SDR together are drawing more power than an unpowered hub can provide.
[Nexus 7 General] porletto:
Ahhh. Than makes sense. I will be installing a powered hub in the final build, but for testing I was powering the whole rig through the tablet. I will test tonight. Thanks!
[Nexus 7 General] tlman12:
I'm doing this with my Toyota Tacoma, my problem is the DAC. I'm looking for something under $80 preferably under $50 usb with rca outputs.

i got Behringer UCA222 and it does work and it puts out good sound to my eq but my problem is that it has a power on POP to all my speakers.

anyone have experience with any devices that go usb to rca and don't have a power on pop, I have a 7 band eq to clean up the sound so i shouldn't need anything too high end.

I was thinking about trying this one next

[Nexus 7 General] papinist:
you should try a different way: try a power adapter with delayed power to amp, like the DCDC-USB. I use it with the same Behringer DAC and I have no power on pop!
[Nexus 7 General] ryanjv:
I had the same pop as well as alternator whine. I bought the Stinger SGN20 Ground Loop Isolator

http://www.amazon.com/Stinger-SGN20-Ground-Loop-Isolator/dp/B002ZRQ3PW

and it went away completely. I didn't even need to hook up the extra ground wires on the isolator

I use the behringer UCA222
[Nexus 7 General] tlman12:
i have a ground loop cause i too had the alternator wine. oddly enough i reversed the ground loop (even though there is no indication of direction) and the pop is much softer, still there, i still don't like it but at least i don't think it's going to damage my speakers at this level lol. I wonder if it's getting too much power at once when i turn on my key, i have a 2.1 amp 12v adapter powering the system.

i'll leave it for now and revisit it later. i just got a N7 gen2 in the mail today so i'm going to be setting that up to swap out my gen1. Maybe that'll make a difference maybe it won't.
[Nexus 7 General] techneut92:
thank you :) arduino controls added

Great idea you had there! i recently am trying to build it in my peugeot 106. which doesnt have double din.

but that project is still in progress. maybe i'll post it too someday. (this is my first post ever on XDA just wanted to share some knowledge :) )

for DAB+ / DRM radio i bought wavesink plus. it works with the RTL2832U. cant link it yet as new member

for the volume controls.. I use an arduino uno R3 (atmega16u2) which i randomly found in a drawer.

(it is probably a lot easier with an arduino leonardo or micro as they have built in keyboard libraries)

****I didn't have time to test this yet on my tablet! (works for pc's)****

I added some attachments:

- picture of my arduino setup

- firmware files to recognize the arduino as a keyboard

- the code i used to get the volume controls working

steps:

all of this is done on a linux pc.

install the arduino IDE and the dfu core

sudo apt-get install arduino arduino-core dfu-programmer dfu-util

open the arduino IDE (in root.. worked better for me)

sudo arduino

copy / paste the code from the attachment volume_control.txt

press the arrow key to upload the code to your arduino

get the arduino in DFU mode (you can google how to do this)

Get to the folder where the hex file is and remove the txt file extension.

cd ~/Downloads
mv Arduino-keyboard-0.3.hex.txt Arduino-keyboard-0.3.hex

Flash the firmware to your arduino.

sudo dfu-programmer atmega16u2 erase
sudo dfu-programmer atmega16u2 flash --debug 1 ./Arduino-keyboard-0.3.hex
sudo dfu-programmer atmega16u2 reset

NOTE: after you have done this, you cant upload new code to the arduino. to do this you should restore the firmware to default.

connect the buttons to pins 4, 5 and 6. to be sure replug the arduino.

now it should work as volume controls :)

atleast on my pc it did.

i'll test it on my nexus 5 soon. if it works i'll let this post as it is.

else i'll just delete it :p

update

works on nexus 5

mute (pin 7) doesnt work

update2

Works in nexus 7 too.

trying to add brightness controls
[Nexus 7 General] mixutuomi:
I got busy and my Nexus 7 project was in a stand still for the longest time. It was also due to the fact that my driving habits don't allow to control the screen on/off by switching power. There was not enough time to recharge the tablet in between and I have been trying out other methods. I do have the bigger charger, but still not enough. Maybe it was also because of the weather here in Finland, -20C did not help.

These are some of the things I tried:

1. To have Tasker switch screen on/off if my phone (BT) is nearby. Was not reliable.

2. To have an LED in front of brightness sensor. Was not reliable.

3. Use the 4 pin dock connection. Tasker actually sees this as AC power instead of USB. But it was again not reliable enough.

Finally I was pulling my hair out and was going through all possible items on tasker. I noticed the headphone jack. That was always spot on when trying it out, extremely reliable. I pulled the back out and soldered wires directly to the board that holds the 3,5mm jack. Audio wires and also two wires to control the information if the jack is inserted or not. There are two contacts and the jack works as a switching contact in between. Now I can connect this to the relay and I finally have a screen that turns on and stays on along with the Spotify play command and screen off and Spotify pause!!!! Yiiiiihaaaa!!!!! And the charger can always stay connected.

Hi guys,

I'm trying to power my N7 with car cig light port using a charger. I bought a 2.1A plug and hooked up to my N7. Only problem is when my N7 is sleeping if I start the ignition the power is not detected (I have a power any sequence to wake the device, set display time out, wifi on, BT on etc) but if i wake the device manually and plug the micro usb it detects power and also charges. This is very frustrating. I'm using a Belkin Dual charger (Cig lighter) with 2.1A for each USB port. Is this is the problem?

I'm using USB ROM.

Power consumption is amazing on this ROM but I cant get the device to wake on power on cause the N7 doesn't detect power from sleep state when ignition is on.

Any ideas? :(:(:(
[Galaxy Note 10.1 Q&A, Help & Troubleshooting] jtyo:
My goal is to use my PC's Ethernet connection as the source for internet on my Galaxy Note 10.1.

I am using Ubuntu 12.10 on my computer. I can go to Network > Use as hot spot > Change the settings to ad hoc, ect.

The PC 'connects' to this network, thus I know it is 'on'.

When I browse the listed Wifi networks on the tablet, the hot spot is not found.

Nor can I manually add the information in 'add a wireless network' (with and without security)

Nor do WifiAnalyzer or SmartWiFi Scanner detect the hot spot.

I have other devices I thought I'd try. My Galaxy Nexus (4.1.2) cannot find it. My Notion Ink Adam (4.1.1) cannot find it.

Interestingly, my Motorola Droid OG (2.3.7) CAN see it, and connect to it!

I have read that ICS and above have had ad hoc support taken out of the wpa_supplicant file located in 'system/bin/'.

I have tried several replacement files, but none have even successfully turned wifi back on (yes, rebooting after replacing).

Note: I do not want to tether internet from my phone to the tablet. I can already do this. I want to use my PC (running Ubuntu 12.10) as the source.

Is there any way to achieve this?

Thanks

I'm on Slimbean and trying to do Start-up Tweaks in the Performance section of Settings. I can click and select Enable start-up tweaks and that selection remains if I back out, reboot, whatever. But if I select any of the Customize Tweaks, when I back out or reboot or whatever, those selections disappear. How do I select them and make them stay selected? I'm not missing an APPLY TWEAKS button as far as I can see. Am I doing something wrong?

Start up tweaks don't stick. So no you're not doing anything wrong. Try ROM toolbox.
[Samsung Galaxy Exhibit 4G] motorapido:
imeserin 1631

Hmm. Why don't they stick? And as far as I can tell, ROM toolbox won't do the tasks I need to set using the Settings, POWER, Start-up Tweaks utility. I want to choose, permanently, the following CUSOMIZE TWEAKS

Zipalign apks on each boot

Fix permissions on each boot

Clear cache on each boot

It seems that I should be able to select these changes in SETTINGS, have them stick and last boot after boot without me having to mess with them again. ROM Toolbox doesn't address those three things as far as I can tell. Am I doing something wrong in the SETTINGS, POWER, Start-up Tweaks section, or is this a bug in CM10 or Slimbean?

No, you are not doing anything wrong. They just don't stick after a reboot. I can't tell you why, ask someone else for that.
[Samsung Galaxy Exhibit 4G] motorapido:
Hmm. I think this is a bug. Why does each choice say ". . . on each reboot?" The selections are listed as selections that will be carried out "on each reboot." If they don't stick after a reboot, why the heck would the software be teasing me with a falsely labeled choice?

A question has been bugging my mind lately. I'm currently on CM10.1 and personally just like CM9 a little bit more. To downgrade back to CM9 to I have to flash back to stock GB 2.3.6 or can I just go into recovery, delete all the data and such and flash CM9?

you can flash it directly from recovery but you'll have to follow these steps:

flash CM9 again

You can use that htc >>micro usb cable<< to plug into your computer. If is the wall adaptor charger output is 5V and 1.0A, you can use it to charge the phone. If is a little less amps, it should be fine, but takes alittle longer to charge.

[Verizon Samsung Galaxy S III] g0thm0g:
Your Rezound cable (and any other micro USB cable) should work in the S3. Take a close look at the shape of the connector port and make sure you are lining the cable up properly. In my experience, the S3 can be a bit more finicky than other handsets in how you line up the cable while inserting it into the port.
