Nexus 7 Head-unit Install
Hi all, long time reader, first time poster. I'm working on a Nexus 7 Car Head-unit install, and figured I would post my working through the install, hardware, software, and kinda just help all the tons of people I see out there who have the same idea, but just have no idea how to go about it.
This is ment to be half a tutorial (once everything is done) and half a brainstorming to give me idea's for things I haven't thought of or considered. I'll be coming back and updating this OP with pictures, and the build as it gets worked on.
Goals of the Install
I want to be able to run my entire car off the Nexus. I have already set up wifi tethering from my S3 to get internet into the Nexus, and thus open up a realm of possibilities. Necessary features are Nav, and Music. I rarely call from my car, but in car calling would be a nice feature to have as well. I also go out to the track ever now and again, and adding car stats (boost, RPM logging, acceleration, mapping) would be great. The biggest reason to do the install is that one the hardware is configured, you literally have a ultimately customizable setup that will take years to outdate.
The Hardware
1 x 2003 Subaru WRX
1 x Nexus 7
1 x Samsung Galaxy S3 (T-Mobile)
1 x MRX-V60 - Alpine 5-Channel Subwoofer Amplifier
1 x 7 Channel Equalizer
lots of hacked wiring
The Software
This is where I would love some feedback on on what I may be missing, better solutions to what I have suggested, and just some general awesome idea's!
Music:
Pandora, Play Music, DI.fm, Soundcloud, Radio.com
In Car Phone/Text:
Talkatak, Google Voice
OBDII Support: (Future Project)
Right now this is not a nessiacty as the hardware to do this could get very tricky. However I know I can read from the OBDII port with a bluetooth OBDII dongel and an app like Torque Lite. However I do own a tatrix cable, and am considering if it would be possible to go from the USB to the tablet, and find an app/write one what allows for the tablet to control the car in real time.
Nav:
Google Navigation, Local
Track Apps:
aLapHD
The Two Builds
There are two ways to go about this. The first would be the simple and easy way which is to hack together a charger wired to the power source of the car, and use that to keep the tablet charged. Then run a 3.5mm audio into the amp, and have sound run from there. There are a few issues with that. 1. There will be no volume control, as the Tablet's buttons will be part of the center console. I suppose I can run a controller to the amp, that will let me adjust volume. 2. This will not allow for the possibility of adding OBDII support.
The second option is to purchase a micro USB dock that does audio out. Hack it apart, and run the audio to the amp, and the power to the power. This would be necessary if I want to do a full USB ODBII connection (I believe, please tell me if I'm wrong), and would be much "cleaner" when it comes time to take the tablet out of the car for any reason (hardwire sync, parking in the "ghetto").
What I need Help with
Have any idea's. Tried something similar and have some tips. Have suggestions for apps, hardware configurations I haven't listed, or just generally want to say "sick man". Please let me know. I would love to have some people who are also interested in doing this join in on my build, and we can work together to eliminate any issues to make tablet installs easier. I will be coming back and updating this OP throughout the entire process so please look for updates!
Thanks All!

Check out a half-DIN equalizer or crossover to solve your volume, fading, equalizing concerns... can't post a link because this is first post!
I'd like do do this in the future... I hope someone comes out with a custom set of apps that make this really cool and easy... maybe even a custom ROM.
Basically what I'd want out of this is:
Auto-on with power. Auto off after 10 minutes of no power. FM radio tuner. Maybe the ability to connect a rear-view camera (wifi?). Bluetooth OBDII would be good enough for me.
I'd also appreciate the ability to connect to at least one camera and use it as a DVR, but I think that it would probably be beyond feasibility with the Nexus 7...
What I really want to see is the ability for the Nexus to be a full Bluetooth head unit. I want it to pair with my phone for both internet (already do this, works great) and have it act as a headset essentially. This is the part that appears to not exist anywhere. The ability for the Android Tablet to act as a hands free device. I mean if a car stereo can fully integrate with your phone read your address book, start and answer calls hands free, stream music, everything from your phone then why the heck not the tablet! Someone needs to write the BT stack that can handle that. Apparently it doesn't exist for android. It exists for Windows, but not Android. That is just wrong. Are there any car stereo head units running Android as their OS? If so can someone dump their rom so we can see what all it can do for a project like this?
I really want this!
I have had mine in the dash for a couple weeks now, streaming Bluetooth to the radio which I relocated, also using NFC sticker to turn on WiFi, bluetooth , set audio volume, screen brightness and start playing music. Tasker to put unit into car mode, its sick! I'll be following, really interested to see what you come up with. My car is N 06 altima and the Nexus 7 fits almost like a glove where factory stereo use to be.

Hi!
Can you upload a picture of your install? I own a altima and I am looking to install the Nexus 7 on my dash as well. And also, did your factory stereo have bluetooth? If not, what are you streaming bluetooth to?
Thanks
Just gonna subscribe as I thought of doing something similar

If anyone can post on his site, tell him to connect two middle pins in usb plug, then it will start charging from the lighter socket.

Does anyone know of a micro USB dock/cable that then splits to power, usb, and audio? I know of one's that will do 2 of the three, but nothing that does all three. Maybe just a USB and power one, and run the audio straight out of the 3.5mm on the N7.
Amp was ordered, and will be here next week. Prelimanary fitment pics coming soon...
Hello, I'm considering permanently mounting a nexus 7 in my car. It seems like the perfect in car device.
With this in mind I have updated my CarHome Ultra app to better accommodate the Nexus 7 screen. I will be posting a new video soon showing it running on the 7.
I've looked at doing this as well, I've always been prevented by the issue of the FM radio. I use the car a lot in places where I get no or poor connection via the phone, but the radio works fine, so loosing it would not be an option as I use the FM radio quite alot.
I've been trying to figure out away to control an FM radio via the Nexus so if anyone out there has any info it would be greatly appreciated.

I am actually currently doing a very similar project with a Nexus 7 and my Nissan 350z
I am planning on installing the Nexus 7 inside my dash (to replace sat nav dash)
HOWEVER
what about routing the power button on the tablet? Because If you cant access the power button the tablet will only get power when the car is on and if you dont use the car for a day or two the tablets battery would go flat and next time you turn on the car the tablet would go into charging mode (screen with charging battery only) and not boot up into android jelly bean.
Theres 2 potential solutions:
1. Open the tablet and wire the power button to a custom one, however on opening it I have found the button is actually a physical push press button and cannot be wired.
2. There is potential to change a file on the android system to tell the tablet to boot up when a charger is plugged in, check these threads:

Never had any problems with it.
Despite working in the car industry and loving gadgets and mod-ing...I haven't really seen what people are up to these days in terms of car mods. The Nexus 7 makes so much sense and looks great!
Hey all
Just to add to the discusion;
Radio/DAB
Frontier silicon are the only company that I can find that do an app that can control an external radio and stream it's signal to the tablet as opposed to picking up the signal over the cellular network.
App:
Their page
http://www.frontier-silicon.com/products/software/DOK_App.html
Play store
http://tinyurl.com/d24gwm4
Module:
http://www.frontier-silicon.com/products/modules/briefs/Venice6_PB.pdf
now the problem with this is, aside from building the module in somewhere' the audio out as it feeds out of the module, but I was thinking I could use some form of y split cables near to my amps 'in'.
Media storage and playback
As far as storage for everything video/audio atc and a player to match I was thinking of useing xmbc
http://xbmc.org/
andriod port;
http://forum.xda-developers.com/showthread.php?t=1813089
and pairing this with a WiFi DLNA HDD that I would wire in remoted off (say in the boot)
GPS
For improved gps I was going to use an external bluetooth gps reciver then allow mock locations on the tablet, there are also a few apps that help with this.
This app seems to have good support and a nice help page.
App:http://tinyurl.com/a9s7gvo
An example of a external GPS receiver
http://tinyurl.com/a339vu7
Hands Free
The only work round I seem to have found atm though far from perfect is this
http://www.scosche.com/consumer-tech/product/1919
it allows you to to 'cut in' the audio stream, but (can't fins the tread now will keep looking) the guy who was playing round with this was having audio issues.
not an idea solution but workable.
before my mind starts melting again;
How I plan to implement the tablet is to use tasker to wake the tablet when power is supplied then shut of down after, if I disable all kinds of connectivity when tablet shuts down then reactivates when it wakes up everything should run smoothly. Power will be cut because I'll wire in the ignition live, like you do in a stereo anyway, an this shouldn't put a drain on my battery to much, an if the dash build is good it shouldn't be too much of an issue extracting the tablet to hard boot anyway.
Volume and Audio
Volume and audio quality is another issue that needs to be addressed.
http://tinyurl.com/d2zbbnf
Seems like an ok work round.
Another way would be to install a direct in-line volume control as suggested in other threads, and put in an external DAC or hardwired EQ.
On a side note I came across this........ http://www.crutchfield.com/p_773AIRDAC/NuForce-Air-DAC-Receiver.html?tp=59282 ........ although you need to use their plug in senders but I'm sure this can be worked round with the knowledge on this forum, an would provide a very nice solution. then again there are quite a few bluetooth devices around. this probably wouldn't allow for in-line controls though.
well thats it for now, hope this helps push this forward to a working system

I recently installed a new head unit in my car, Kenwood DDX470, which I believe is compatible with the revolution. The phones bluetooth connects and allows the track controls to control music, both on spotify and all access. I switched from spotify to all access because there was a 4 steps process that had to be followed in order to successfully sync the bluetooth, and because I heard that spotify was not necessarily very compatible with android devices, and because I heard that all access might show the track information once linked up. I'm pretty sure the phone has the ability to transmit metadata, track info, because it does so no problem with music stored on the device, but unfortunately it does not do so when streaming through all access or spotify.
I saw that there is a link to install a 3rd party app for the samsung SG3 and tab but it didn't work for my phone. I've talked to all access support, lg support, best buy, and verizon, and there appears to be no solution. I know that transmitting metadata is possible while streaming, since my brother is able to transmit this information on his iphone for both music streaming subscriptions. I'm, assuming this has something to do with the blue tooth stack of the phone, but I really don't know. Any insight into this problem would be great. I travel a lot for work and am a bit of an audiophile and this is the last problem I am having getting the system linked up properly. Hopefully one of the genius' at xda will have a solution. Thanks!!

First off, the iphone is a whole other animal when it comes to car audio. You cannot compare what you do with an apple product in your car to any other device. Period. Now, second, I have never been able to get meta data to show through bt on the revo. I have had this phone for 2 christmas's and can't recall ever seeing meta data displayed.
Pandora and Spotify work absolutely flawless on my wifes jvc w/o metadata. You could try and search the playstore for a manufacturer app for the radio. I know pioneer, jvc, sony have them. See if that helps. But most likely, you will have to upgrade your phone to get that to work.
I've been a car audio installer for over 10 yrs and android is the blacksheep of the car audio world. Now, the pioneer app radio, through hdmi, works flawlessly with the revo. You can even get screen mirroring to out put the revo's display to your other monitors if you have them. :victory:
Is there any way to get mirrorlink working on the Nexus 6?
Not sure what mirrorlink is. Do you mean Miracast? If so, I don't believe it works. Chromecast works great for screen mirroring your Nexus 6 to a HDTV.
Found this searching for compatibility... One application for MirrorLink for those that didn't know is Pioneer head units like the AppRadio so you can mirror your phone's screen onto it...
any luck?
Is MIrrorlink compatible with the nexus 6? If so, anybody know how to enable it?
My understanding....

From what I have been told neither Mirrorlink nor AppRadio are compatible with Lollipop in general and the nexus 6 specifically. Your only option at this point is Android Auto which works well if you have the supporting HU from Pioneer. However, at this time, not many developers have made their applications compatible with it. When the 2016 car models start rolling out with AA preinstalled in their HU, then I believe we will see a flood of apps moving into the platform.
Google needs to start supporting MirrorLink on Nexus phones. I have a Nexus 6 and the Pioneer AVH-4100NEX.
Android Auto has been a horrible experience so far. It worked at first, for a couple of months, and then I don't know why (Android update maybe?) but suddenly it stopped working and hasn't worked since.
Even when it did work, there were some VERY annoying things:
1) if your phone is plugged into the USB cable, Android Auto launches, and as long as you're still plugged in I couldn't find any way to temporarily get out of Android Auto (such as if I want to check my email or some other app on the phone). Or if I want to listen to a YouTube video (or watch it from my phone, lets say I'm the passenger ok?), then I'd have to un-plug the USB which means my phone isn't charging.
2) The other really annoying thing is that Android Auto limits developers in how many screen clicks user would need to do to get to content (including, clicking the down arrow to browse through a long list). Where this is a problem for me for example, is my Spotify playlists. Android Auto will only display about 10 or so of my playlists.
So I find myself disconnecting the phone from the cable and just streaming over bluetooth.
In fact at first I was really upset that my phone was no longer launching Android Auto at all and stopped working with my Pioneer AVH-4100NEX, but now that I am just able to leave the phone charging all the time and have full access to my phone apps, all my spotify playlists, and am just streaming over bluetooth I'm not really sure I want to fix Android Auto.
What I really want at this point is to just MIRROR my phone screen to my head unit. This way no matter what I want to watch or listen to, it doesn't matter if "Android Auto" supports it or not. I can put on YouTube videos, or anything I want.
So this gets me back to Mirror Link, I don't know why Google or Motorola is not supporting it, MirrorLink from what I've seen should be another viable option for Android users (and for now I think a better option than Android Auto)
I'll be posting this reply as a separate topic as well, here and in Google's forums because it needs some attention.
Thanks
Ill repost this here as well
You have to take into account the many laws in different places concerning cell phones and driving. In some places you can get a ticket just for having your phone in your hand while driving. And now they are cracking down even harder on it. Also some OEM have been known to block some cars from working with devices like that. It was found that one samsung device had a list built into the OS that blocked a number of different cars from working with Android Auto. This I can only assume came from the Car manufacturer.
If I had a nickel for all the distracted drivers around me, well, I'd have a lot of nickels!
I have just got my P20 Pro, it seems like a great phone so far, but I have one nagging issue.
When I connect my phone to my car's (2015 BMW 3 Series) Bluetooth the now playing metadata of the audio being played is not being passed correctly. So if I play audio from Google Play Music or Pocketcasts the head unit on my car will show either Unknown Track or the track data of the first item on the album or the playlist. The audio itself sounds fine and I am able to skip tracks, select new albums from the car's controls, so it seems some information is being passed correctly, it is just that the info of the track that is currently playing seems to not be working.
Has anyone else encountered this?
At this point I have to assume it is the phone, as my Galaxy S6, S7 & S8's all worked, but I guess it is technically possible that could have been a workaround put in by BMW as they were such popular phones. Hopefully Huawei will sort this out, it may be an underlying Oreo issue as threads like this suggest that Bluetooth issues were around when 8.0 launched https://productforums.google.com/forum/#!topic/nexus/E9Q2lyFYRgI
I have done some more digging on this issue and I suspect that is might be something to do with the Bluetooth AVRCP version that the phone is using. Normally in Android (since 8.0) you could adjust the AVRCP version from within Developer Options, but for some reason this is not available on this phone. My Galaxy S8 was using AVRCP 1.4, so I suspect that this phone is using 1.5 or 1.6 and my car does not like it.
I have emailed Huawei to ask for clarification. At this point it is the only real issue I have with the phone, but it will annoy me if it isn't resolved quickly. I'm going to pester BMW too to see what versions of AVRCP they officially support.
Don't have these issues in the car, head display current track etc via Bluetooth ... Use this in a Nissan
Everything works as it should with my Pioneer headunit using Spotify
I just posted something related (possibly) in the RAM/Battery Management thread - I have issues with the Audi MMI Connect app, losing connectivity and so on.....does seem that the P20 Pro handles Bluetooth (no rsap?) and background process management quite differently to my previous phone (Galaxy S8+)....also hoping quick resolution, as love the phone!
Search facility not working in car
Hi
I've just put music onto my P20 pro and it plays fine on the device and the car, however, I can't use the search facility on the car (BMW, 3 series, 2017) to change track. I can do this on the phone. Any suggestions? I put the music onto the 'Music' app (dragged and dropped from my iTunes folder- don't know if this is relevant. Any help would be greatly appreciated as without being able to use the car's search facility and come in and out of albums/ artists is useless. Should I have put the music into somewhere else?
JQ
P20 PRO and BMW - bluetooth issue
Bojanglez, did you find a solution? I got the same issue with P20 PRO and BMW X4... so it seems a problem linked to that phone connected to the BMW multimedia system.
With my previous phone, an ASUS Zenfone, everything was fine.
It may be a BMW issue to, maby P20 pro isn't compatible with BMW or Audi. I know that some manufacturers put all in to be compatible with ios and some larger manufacturers of phones. It could be that car manufacturers don't test Huawei phones and don't support them.

No Huawei Garbage bloatware issue, my is random something is normal, most times it plays music but gets stuck on providing music playing info.
Same issue here with my 2016 Toyota rav4. It plays the first track and shows the metadata but then as the tracks keep playing the metada remains the one of the first song. Definitely an issue with Huawei. Their music player works just fine. I think it has to do with the poor Google integration and their need to force that half baked apple wanna be emui down our throats. It should be Oreo but looks and feels like gingerbread.
Hi all, I have an update. I have resolved the issue, but not quite sure which of the following specifically fixed it.
Huawei software update
Renamed by phone in Bluetooth settings
Updated to the latest BMW firmware (from their site)
Messed with some of the Bluetooth settings in Developer Options on the phone
Unfortunately I did all these at pretty much the same time so I can't say for certain which one fixed it, I think it was the Huawei software update as after I updated my BMW firmware I still had the same issue and also in other BMWs I tried. I also noticed that the Bluetooth was dropping constantly in my wife's Puegeot 3008 so that's why I played with the Developer Options. For anyone interested I havethe following now set:
Codec: SBC
sample rate: 44.1khz
channel mode: Stereo
LDAC playback quality: 990kbps/909kbps (optimised for connectivity quality)
HWA playback quality: Best effort (400KB Optimised for connectivity)
HWA Latency: 50-100ms
So I now have track information and basic controls using Google Play Music and Pocketcasts. It does not seem to like letting me browse my library though, but it is at least functional.
Also I changed my car, this was not because the BT didn't work It worked in my 2015 3 series before I changed it. I now have a 2018 4 series and the behaviour is the same, track listing and skip functionality but no browsing.
I have installed the most recent firmware update on my 2 Series 2017, I see two fundamental issues. One is, by using your phone normally, no issues should arise most of the time but still random sync issues with metadata can occur. The second issue is, no matter how good your phone behave and how well synchronized the metadata is, once you open Android Auto app, everything goes to hell and you are back in square one.
To fix it, you should deactivate auto start when connected in the app (or not using it at all), erase your car from devices in bluetooth config within your phone. Erase your phone from the list in your car. Change the phone name. Start over with the synching process. Check for correct metadata in the car. If not working repeat. That should fix the problem eventually.
If you like very Android Auto very much, get used to see the songs information in your phone screen rather than the car.
I am also having the same problem, Huawei P20 Pro and Sony XAV-601BT head unit. I've tried enabling all the permissions in Spotify, cycling the connections, renaming the phone.
i have Pixel 3xl with Android 10, - Bluetooth connects fine there is no metadata - song info. this problem started with 8.1 Android version and I have not been able to get it to work. I really cant believe google cant fix this issue or even aware of it. plenty of threads on google. I think they all use Iphone, i am guessing ...this is very annoying. I have change the avrcp version from 1.4 to 1.6. no luck, also I read that turn off battery optimization on Bluetooth. no luck. anyone else here having similar issue??
I wanted to share how to solve the problem of using bluetooth on a second phone having another mobile already connected to Android car.
The easiest solution would be to use a duplicate of the Sim card, but in my case my telephone company does not have that service and cannot be hired.
As you know, at the moment that a mobile phone connects to Android car, it no longer allows us to pair a second phone and use it to make calls via bluetooth, forcing us if we want to make calls to use the one that is connected by USB to Android car.
Well, using an application we can disable the sharing services by bluetooh and thus be able to use the 2nd phone. The negative part is that it is necessary that the mobile is broken.
The name of the application is: Service Disabler https://play.google.com/store/apps/details?id=com.kunkunsoft.rootservicedisabler&hl=en
“IT DOES NOT HAVE THE PHONE WITH ROOT”
To deactivate all the services of sharing via bluetooth is easy, we open the application and type the word bluetooth in the search area and it will already be in the list, and now it is just click on it and we will leave the option to deactivate everything.
From this moment on, all audio from the connected phone will be through USB.

This isn't really an Android Auto issue. But I understand a workaround may be useful if you have a headunit with this limitation.
How many phones can be connected depends on the headunit. My Kenwood will allow two phones to be connected and both can answer and make calls. Usually, I have my Pixel connected via AA, and my wife's iPhone will connect via Bluetooth at the same time. I can even select Bluetooth on the headunit and play music from the iPhone. In fact, although only two phones can be connected for calls, it will allow up to 5 phones to be connected at the same time for music (I've never tried that many, though).

Most cars have this problem. I think is very useful, i will implement it. It may be easiest solution. Phone has root to work mirroring so, probably with freeze bluetooth with titanium, could have the same, but havent try it yet..
