Nexus 7 Car Install

I've decided to put together a Nexus 7 car install after pricing up an OEM retrofit for my E90 & quickly getting north of £1200 with no guarantees that everything would work as I wanted.
I've used Android devices to provide navigation & audio since getting a HTC Desire many years ago, but I've been caught out a couple of times recently using navigation on long journeys with my HTC One-X completely flattening its battery despite being on charge the whole time!! The last time left me navigation-less in a strange city, in rush hour traffic, with no way to contact anyone.
I've been reading around Nexus 7 car installs today & everything that I would like to do seems to have been done before, but I'd like some ideas for the best way to pull it all togther.
The main use for the Nexus will be to provide navigation & audio. I gather that Timur's kernel - USB ROM contains features which are suited to using the Nexus in a car install - are there any other ROMs I should have a look at?
I would like the install to look as professional as possible but be removable & reversible, so I'm thinking of a mounting it in a SHG-NX2000, & I would prefer to use a single USB connection to the Nexus rather than a USB & 3.5mm so from my googling today I gather I can achieve this with an OTG USB cable & a USB DAC.
I've not used an OTG cable before, but the ones I've seen on ebay seem only to be a couple of inches long - can anyone provide a link to longer one or can I just use an extension cable & stick the OTG cable near the hub? The idea I've got in mind is to run the host OTG cable from the Nexus into a powered USB hub located in the glove box or behind the dash. I would supply the power to the hub from a DC-DC convertor to make sure everything gets the power it needs. Are hubs usually wired to supply power to the host device as well as the connected devices? Are OTG cables available which allow the power to be supplied to the host? If so, I could use one of the ports on the powered hub to supply power to the Nexus via the OTG cable.
I don't have a spare line level input to my stock BMW headunit, but I do have an aux in on a 3.5mm socket which I don't mind re-routing & hard wiring to the output of the DAC - can someone link to a USB DAC best suited to this task?
I would also like to install a reversing camera. There are cameras available which either replace a license plate light, or mount around the license plate - I would prefer to use one of these over a webcam. I had an idea of using an Easycap to connect the license plate cam to the USB hub - has anyone done this? The license plate cams pick up their power from the reversing lights - is there a way of using the fact of the camera powering up to switch the Nexus to auto display the feed from camera when the car is put in to reverse? Taking this idea a step further, has anyone configured a system where if the car is then subsequently taken out of reverse gear the Nexus switches to a forward facing camera either for a fixed amount of time or until reverse gear is re-selected to give you alternating rear/forward views when parking up?
Shopping list so far:
Nexus 7 (1st gen) £119
SHG-NZ2000 £22.39
DC-DC convertor £5.50
10-port powered hub £6.19
Micro USB OTG Host £1.99
E90 License plate light CCD camera £17.00
Easycap £3.37
USB DAC £11.49
Total so far ~£185
Anything I've missed? Better components? Cheaper prices?
Any help or ideas greatly appreciated

I would think the only way for a rear cam to work is to modify it and your tablet ...no usb input... You could try to use the housing of a rear cam and put a web cam it and seal it up good then use that .... That way you'll get a wide veiwing angle ....

I'm not sure I understand what you mean by 'no usb input'? I'm talking about connecting the CCD camera via the Easycap to the USB hub which is connected to the Nexus. It is because I don't think I'll be able to reseal the housing well enough that I don't want to use a webcam, plus the CCD cameras are powered when reverse is selected which I'm hoping should make driving an event easier.

Found this on a BMW forum:
Finally sewed up my Nexus 7 install!
It's very similar to what I had in mind. I've ordered the bits so I'll update this thread as & when progress is made.

Reversing camera hooked up to Nexus 7 via UVC Video Grabber
Nexus 7 Backup Camera - UVC Video grabber

Where do you buy that ?

i was thinking of use official dock mound to the dash to make it look professional and removable(dock + magnets).
not sure if the usb on the back of the dock supports otg or not, cos i wanna connect up reverse camera and dac aswell

I considered doing something similar, but when I looked into it, it would seem that the official dock only charges and passes audio

Hi there,
I was just wondering if you had any success with the camera? I've got a Nexus 7 install and want to wire in my existing Rca cam. I'm sorting out the reverse signal with a joycon exr steering wheel control but I want to know if the easycap thing you linked to earlier worked as a capture device on Android or whether I'd have to go for the UVC grabber in the other link which definitely works but is much more expensive!
Thanks!

Any update on these types of cameras?
I want to do the same thing, except the camera is in the front (not the back).
Any success with the EasyCap? It seems they have bad reviews on amazon, but maybe they work great for how we want to use it.
Also, have you tried using a 4 channel EasyCap? That way we could hook multiple cameras.

nexus 7 install
In the process of doing the same to mine.
2013 Nexus 7 rooted with automateit and tasker .
So far I've managed to get it to launch apps when power is supplied and shutdown when power is disconnected. But does anyone know of a way to get it to power on when power is supplied? I've tried reboot when power is supplied, but that only works if the tablet is already on.

Nexus 7 in-dash car install in Citroën DS5

Hello all,
I've installed a Nexus 7 model 2012 inside my Citroën DS5 (French car). The project is to replace the small original LCD monochrom monitor for car audio (for multimedia only, no GPS).
There was no important mechanical modifications needed, because the original dashboard supports 7 inches first mount original GPS.
The original radio unit FM + CD reader + control buttons are kept. The tab will only be used as external peripheral for multimedia :MP3 and GPS.
In this car I've a duplicate screen on main driver dashboard about FM radio station, so when using FM Radio I can see the selected channel on this screen.
So in fact the main radio unit will 90% be left in "Auxiliary" source and the other 10% "FM radio" source.
Part list :
- Nexus 7 2012 with USBROM
- OTG cable
- USB Hub
- DC to DC 12V to 5V - 5A converter (found on ebay)
- 3 push buttons extracted from an old credit card format IR remote control
- RF cable
- Some wires, soldering material...
Applications :
- JetAudio Music Player (My advice, the best one for in car use)
- Night mode
- Android Weather Clock Widget
- Mappy GPS free (French GPS app), alternatively Tomtom
Installation schematic :
Coming soon. I'm not able to post image links as new user. See attachement.
Notes:
- I've added external GPS antenna because reception was bad using built in antenna. I've just soldered a RF cable on the GPS antenna connector on the mainboard and soldered the small GPS antenna at the end of RF cable,
- The 3 power on and volume buttons have been deported to accessible part of the car. I don't need to use them usually, but in case... I will be able,
- First tries by connecting DC 5V to the USB hub were showing really slow charging. I'v found a thread studying that and it's mainly due to the cable loss. standard USB cable are low section, and as I was going through USB Hub + USB cable + OTG cable... I was measuring less than 4.85V at tablet connector instead of 5.1V at DC converter output. So I've soldered highest section power cables directly after Micro-USB of the tablet and limiting the length to 50cm... Now good success with fast charging.
Tablet Installation :
Coming soon. I'm not able to post image links as new user. See attachement.
I'll try to let this thread as alive as possible.
Thanks for reading, and sorry for my English langage mistakes.

That looks like a very clean install. Nice post.
I have been trying to figure out how to install my Nexus 7 to my car but as it already has a stereo I want to keep i have to find another method.
awesome stuff though !
---------- Post added at 03:15 PM ---------- Previous post was at 03:10 PM ----------
I forgot to ask, is heat a concern for the unit when installed like that and... with the tablet screen on for extended hours is burning an image into the screen not a concern when doing these installs into cars?
I have a S3 which i use as my GPS and do some long road trips. It has now got the point where the map app has burned into the screen faintly. I am wondering if the Nexus 7 would suffer the same result?

Nice, thanks for sharing.
I'm tempt to start something like that in my car, but for now i'm only collecting ideas.
How did you managed to get FM radio on N7?
So far, AFAIK people can get radio on Nexus 7 with bluetooth tethering (unless your N7 has 3G). But then you need a 3G or 4G plan in other phone...
I'm maybe build a customized menu with Zooper Pro, with icons for GPS (tomtom), Radio and USB Audio (jetaudio)..(something fancy like XBMC) and maybe later could add other functions like video or internet browsing.

I've edited main presentation, but I would like to precise that the main stereo unit is kept in this project. Only one simple screen has been removed to be replaced by the tablet. I had the chance in my car to be able to find easy area to put the tablet without needing to remove important unit and replace main stereo.
I'm suprised and not aware about LCD screens that could burn when same image shown during long period. Thought it was for the old screen technolgies. On the other hand, a lot of actual cars are embedding touchscreen tablet similar by default. So I think the technology is now proven. Anyway, I am not using any specific dashboard app for the tablet and so using directly the applications and switching for instance from GPS app to music app.

As edited in main presentation, the main radio unit is kept. So FM radio is left to the main radio unit. I'm using the original buttons below the tablet to control the radio. I'm also still using the original stereo volume buttons including the ones at steering wheel.
For the moment I'm using the standard android desktop and widgets that fits to my utilization, as I only use 2 main application for my tablet ; One for GPS and the second for music.

Few updates since last time on this topic.
I've encountered slow charging issue already encountered by some people. It was discharging faster than charging...
It's linked to the connector inside the tablet between USB PCB board and Mainboard. The solution I've found is to solder directly the USB power to the ribbon cable by removing plastic protection enveloppe on it. Now no issue anymore.
Sometimes I had also issues on GPS reception. I've also soldered a 2m length RF cable to the GPS connectors on the board, and passing it to the dedicated windshield area (UV metallic shield free area). I let a 5cm length internal wire of the RF cable visible on this area, and get better GPS fix statistics.
I need to work on this part to finish a proper installation instead of wire visible on the top of the windshield.
On the other side I've also finished the installation of the rear view camera. I'm using USB video grabber (EASYCAP type) + car camera rear view (easy to find for few dollars on the net).

OTG GPS & Charging on 5th gen?

I see a thread about OTG charging not being possible due to the Amazon kernel that is a few months old, has anything developed as far as this? I'm planning to install one into my cars dash and it would be great if I could also add a GPS module to it but obviously I need charging capability since it will be inside the dash and always plugged in.

Nope. You get one or the other. That's unlikely to change as such use does not benefit Amazon (no clicks). You might consider a Bluetooth receiver which would leave the USB port available for charging.

Fantastic I never knew bluetooth gps modules were a thing! Do you personally use one? I'm not too keen on modern android especially when it comes to separate devices like this, will I be able to use it with any maps app and be able to set the default gps device or will it only work with certain apps designed specifically to use one?

Search Amazon "GPS receiver bluetooth". Pricier than usb receivers. I do not use one; prefer devices with integrated chip. However, I have tried a USB receiver on this device to verify it works. No personal experience with BT receivers. Another poster mentioned an app that would permit reception of GPS data from another device such as a phone. Good luck.

Remix OS carputer build

Hello guys, I'm planning to build my first carputer. 2 years ago I have modified a tablet, Asus zenpad 8, very similar to Nexus 7 in my opinion. Now I want something more.
What I want:
Fully automated pc that works exactly like an android head unit but much better and more flexibility when it comes to external devices like an external DAC with optical output. Actually this is the main reason for not buying an android head unit, didn't find one that works very well with an external DAC. Some other things that I want from this carputer: the compatibility with steering wheel controls, backup camera, fm or even DAB radio, gps, phone calls( via bluetooth), 4G internet and so on. Many of those things are pretty simple to integrate, will talk about them later.
The components:
1. The pc - didn't think about it yet because there are loads of mini pc on the market for good prices. The only problem I'm thinking is the start up on ignition. First I wanted to go for a Remix mini pc but I don't know how could I make it start on ignition and after that automatically play the last song. If I would go for a normal PC, I found a smart PSU which has the possibility of ignition start and stop and puts the computer in sleep mode. That way I will avoid the waiting time for the boot, in fact the computer will be permanently turned on. The only problem I can think of, is the compatibility of this PSU with the android Remix OS. Is it possible?
I've tested the Remix OS and I like it, very quiq, easy to use in car with a touch screen, support all the external devices( wifi, 4g, fm and DAB, external DAC with optical output) and the launcher can be changed. I know I can opt for Windows OS and that way I will be sure that the PSU works but in my opinion windows is not so "mobile friendly", not so easy to use in car.
2. The screen: not so many to talk about, found on ebay some 9" tft touch screens, very good resolution, hdmi connectivity and USB for touch. The best thing with these screens is the AV2 input for the backup camera. The screen automatically switch to this input, has guidance lines, and this way I solved the problem with the camera. And also is quite cheap.
3. Steering wheel controls. Found on ebay the Joycon steering wheel adapter that is compatible with Android. I just have to make an initial configuration and that's it, nothing more, simply works through USB.
4. The other external devices: all of them can be found on ebay for good prices. The only thing that worries me is the bluetooth compatibility. I remember when I built that Asus zenpad tablet, I couldn't find a solution for this. Now my question is, what type of bluetooth adapter should I buy and how do I integrate this in the carputer. And I'm not talking about physical connection, I think I will need some kind of software, app, that knows what to do with this bluetooth adapter.
So, in the end, I would need some help regarding the ignition start, just the hardware part of it, all the other automatic things (launch the app and play the song) can be made with tasker very easy. Also I would need some help with the bluetooth phone calls.
Hope I didn't miss any important thing and I will appreciate any help. Thanks.

Have you thought about using a rock 64 single board computer like a Raspberry Pi that Android is really supported something like that could work really well as it has gpio outputs for various functions USB inputs for audio dacs and DAB radio and can work with touch screens or even projectors for heads up.

The truth is I know nothing about raspberry pi, heard about them but nothing more. Can you please explain a bit more? Is it possible to make it automatically turn on/off on ignition? How? Apparently that's the hardest part of the job. I've read on the internet that Remix OS doesn't work very well with stand-by function and if I'll make it to shut down completely, I'm afraid that will take too long to boot back. I was thinking about Remix mini pc and a controller that simulates pressing of the on/off button simultaneously with the ignition but it has to be tested.

So, quickly searched on google about raspberry pi and banana pi possibilities, there are some power supplies for in car use, basically they simulate a shut down from the button with a delay. That looks very good, very easy to do and also very cheap. But, how fast can boot a raspberry or banana pi running Remix OS? Does anyone know?

To make it turn off and on with the ignition, just plug it into a 12v line that is powered when ignition is on. Generally the 12v line to your head unit fits that criteria. If you want constant power to keep the device in standby mode, you can connect a relay to an a wire that is powered when the car is powered, then use the relay to short the pins of the standby button.
For boot time, you can achieve quite a bit of improvement by getting the fastest sdcard you can buy.

Thanks for advice. I've searched on youtube how android works with raspberry pi and in my opinion they don't do it very well, I mean it struggles even on youtube playing videos. So, I bought an ssd hdd, 32gb and made some tests on my pc. Found a version of android 7 special made for in car use and I'm quite happy with it until now. This android has a "special" feature, when the power button is pressed the pc shut down without displaying any confirmation message on screen. That means it will work perfectly with an intelligent power supply like m2-atx, m3-atx etc. In the next few days I'll get a new pc, micro atx mainboard so I'll begin the tests on that. Until now I've got a boot time around 30-40 seconds. Is not a bad time but I'll try to remove the unnecessary apps from startup and see what happens then. I'll post some pictures or even videos when I'll have good results. Any advice is welcome. Thanks.

Why don't you get an android head unit?

I think you didn't read, I couldn't find any that works with an external sound card(DAC). My audio system is quite expensive, made for sound quality, and of course I want the head unit to be as good as possible. An external sound card with optical output I think is the best you can get.

Google search "raspberry pi alternative" theres lots of these little gadgets now adays, raspberry pi 3B is one of the most popular ( and cheapest) but there are more out there that are more powerful & better hardware.. The ASUS Tinkerboard is becoming popular as well I think I may be getting one for a streaming machine.

I've already purchased the PC and ordered the PSU. The price for all those components(+ a 30gb ssd) was under 100£ so not very expensive. Why I went for a pc instead of a single board pc? I don't know, maybe because I have no previous experience with them. Yes is true that is way much bigger than a raspberry alternative and the power consumption as well but I don't mind, maybe in the future when I'll get bored again I will try one of those pc's.
So, I've tried to install the Android X86 64bit (there is one version on internet with a patch that removes the confirmation message when you want to shut it down) on this pc with no success, all I've got was a black screen or a continuous reboot. Found out that Android X86 64bit is not so friendly with AMD cpu's. Should've search for that before buying it. Anyway, tried the 32bit version so that one works very well but I didn't find any with that patch installed. How can I remove that confirmation message when the power button is pressed?
Thanks.

first tests, quite happy with it, still lot of work to do.

Android Auto / Apple Carplay via T Link app

Hey there
so i saw this app called T Link the other day being used by someone that claimed to bring wireless carplay to every Android Head Unit.
Does this app work? I tried it out myself and i keep gettings errors but no connection.
Does the app need Root Acces maybe?

Link to the app. The only thing I find is a screen mirroring app with bad reviews, specific to JVC headunits, which uses a USB connection, and has nothing to do with either Carplay or Android Auto.
First, if it provides Carplay capability to an AA headunit, it would run on an iPhone (IOS), not Android. Second, if a headunit doesn't support wireless AA, no app is going to allow a Carplay device to connect to it wirelessly, so "every Android Head Unit" - nope.
Seems you're missing something here.

Hi. I dont know about apple product but as far as an android user the T-link app provides for me wireless AA without fail.
Have not once experienced a dropout of connection loss or anything.
Only issue is what is an AA issue, and thats maps not being able to switch day/night mode by itself
Best regards
Using Tlink 1.7.7

Link to the app. The only thing I find is a screen mirroring app with bad reviews, specific to JVC headunits, which uses a USB connection, and has nothing to do with either Carplay or Android Auto.
First, if it provides Carplay capability to an AA headunit, it would run on an iPhone (IOS), not Android. Second, if a headunit doesn't support wireless AA, no app is going to allow a Carplay device to connect to it wirelessly, so "every Android Head Unit" - nope.
Seems you're missing something here.

The Tlink app is installed on ur android headunit. It connects your phone, either android or Ios to AA.
So he is actually spot on in his discovery
Best regards

Hey guys thanks for the help but I think the problem that I am having is a different one now.
So my headhunt does not support Apple CarPlay from the start.
I bought a adapter and tried to install the app that It comes with but nothing… no signal.
So the issue seams so be that there is not enough power coming out of the USB port.
When I use a splitter and plug the end for power into the lighter usb charger and the data one into the usb dongle it works no problem but it looks ****ty …
Any way or any adapter that I can get this fixed with?

Btw the head unit charges my phone without the adapter for about 3 seconds and then it Just shuts off

So, has nothing to do with Android Auto, where apps are not installed on the head unit. So, he's actually completely missed the mark for posting in the wrong forum.

Yes and no. Since you use the Tlink app to connect to AA. And that is installed on Head unit. Its not really a AA question, but related to that.
Since some need either Tlink or Zlink to connect to AA it might be more correct to move to a different thread than one thats about AA, but then again.
Im not a mod so not sure =)
But this is a different matter and not what was supposed to be the topic
Some with a bigger brain will surely help us out

I have seen someone talking about an adapter for this specific reason, but tbh you might wanna look in the headunit threads.
Tho if you google adapter for carplay there is quite a few hits, tho seems expensive.
Try and look in TS10 / Px6 head unit threads, there are some clever ppl there who is really helpfull
Best regards

The carlinkit 4.0 I am using is very good, it supports both wireless carplay and wireless android auto.
