Recommendation for BT or NFC Car Reciever

Hi all
Just bought my first decently specced android device in the nexus 7 2nd gen
I would love to get the device in the car and connected to the cars audio system with no hacking of the dash so basically just want to mount and play music through the car - apparently I need a BT /A2DP or NFC Reciever
I could connect to the cars system using either a 3.5mm audio jack or
if possible and if one exists that would work to the cars radio (so creating a radio frequency to tune into)
I already have a cheap one off ebay that I havent been able to get working at all - the nexus says it has paired but cant get a connection on the radio frequency
Does anybody have a half decent recommendation in the UK? What is the preferred way - NFC is the newish tech?

Sony SBH20 is your answer (i'm unable to provide the link in the comment but a google search should easily give you the link).
I bought this and i've been using it everyday all day long connected to my phone and laptop. Pairing with NFC is a boon!
I reckon this would fit your requirements of easily plugging into your car stereo system really well. Lemme know how it goes

2013 N7 Dock charge/audio?

I am looking to install the LTE n7 in my car, I havent purchased it yet because I am trying to figure out if there is a desktop dock that includes charging/audio out or just audio out, the reason being I dont want to Embed it into the dash i wanna be able to take it out, the Old n7 dock is perfect is there something similar for the new one? I can use the QI charging and embed it into the dash but for the audio bluetooth is a problem.

Nexus 7 as Head Unit help needed

Hello everyone. I am new to the site, and fairly new to car audio.
I was hoping I could get help figuring out what I need to buy so that I can setup my audio for my car,
I have a 1998 Mitsubishi Eclipse GSX with infinity sound system( Minus the stock infinity amp, and oem radio/headunit)
I want to run all new wires to each of my speakers. I was thinking I need 14gauge wire.
I want to use a Nexus 7 Tablet as my head unit.
I would like to use a wireless charger for the tablet but I don't know if that's practical. If not then I will need a solution for charging the Nexus 7.
I want the tablet to be removable. I want to be able to tune into local radio stations.
So what I am not understanding is do I need to keep my current headunit and connect the nexus tablet to it via auxilary cord?
My headunit does not have bluetooth, and it was designed for use with an iPhone.
If I keep my current headunit how will I adjust the radio station from my nexus 7. I don't really want to be pulling the tablet out each time I need to change stations.
Then my other question is, do I need to keep that headunit to use a nexus 7?
I think that keeping the headunit paired with the nexus will probably be easiest because then I know I have a receiver for radio stations, and cds.
Also I need some help deciding what amp to get, what sub, and new set of tweeters.
I think I need a 4 or 5 channel amp
A 10 or 12" sub
I dont really know much about what brands to get, if I do or don't need crossovers.
Also some sound deadening. - which to get.
This was put in by local audio shop but they screwed me over. So I want to do it right this time myself. I am new to car audio, but I am familiar will basic electrical.
This is what is installed currently.
Deck (Pioneer DEH-6300UB)
Front Door speakers (RockFord Prime Full Range 6.5" 4ohm 3-way)
Rear Speakers (Rockford Prime 6x9" 4ohm 3-way)

best thing you can do is to split your project in to smaller parts. get them done in the order you think you can do it.
i recommend you get an N7, get the Behringer UCA 202, get a DAB stick and get SDR touch working. then figured out other parts as you have the time. it will be time consuming.
research what others have done.

Thanks for the suggestions!
I picked up google nexus 7 32gb 2013 version from bestbuy.
I will look at the other items on amazon in a little bit.
If you know a good thread that describes the process to help that would be great too!

I'd recommend getting a compatible amp and linking your nexus straight to it. Also, if you have a wifi hotspot, you don't need a radio, just use tune-in radio. it has all the local channels.

Thanks for the video! Anxiously waiting to see the rest.
I decided that the wireless charging is not going to be practical seeing as the tablet basically has to be touching the pad anyways. So hard lines will be fine.
Here is list of parts I think I am needing. Let me know if it looks good.
Nexus 7 32gb 2013 edition (Have)
Double Din Dash kit for my car ( I can't seem to find a kit that is made for my car? 1998 Mitsubishi Eclipse GSX) I have a single din dash kit maybe I can modify it to work...

10" Rockford Fosgate R2D4-10 Prime R2 DVC 4 Ohm 10-Inch 250 Watts RMS 500 Watts Peak Subwoofer
Tweeters:
I don't know suggestion please.
Sound Deadening :
Some cheap but reliable: Suggestions
Wiring:
Anything special I should use or just some 14gauge?
Accept for what goes to amp which I will use 4gauge
I want to make this a removable install so I can attach it when I get in the car and take it out when I get out if I want to.
Also I decided that I will keep the current headunit I have because I do not have a dedicated hot spot for wifi and my cell phone plan only allows me 2gb per month. (AT&T)
So I will need to figure out how to push my current headunit further back.
Does anyone know if there is some app that will allow me to control my current headunit through auxilary or usb from the nexus 7? All I really want to be able to control is radio station, and volume.
Also I have a plan for making the tablet removable I just don't know what would be required. I want it to be a push in push out motion. You press it in to lock in and press again to release it.
So any suggestions for what to get would be helpful.
I was looking at another site and a guy made a box out of plexiglass. That would be good. Then figure out what i need to make the push release work.
Suggestions are needed and appreciated.
If I am missing anything let me know :good:

The Ultimate Car Setup

OK. So 2 years ago I saw a thread on the Nexus 7 tablet forums where someone essentially turn it into a car deck. At the time it was complicated, convoluted and buggy to say the least. Since then its been a thought exercise to make this work. How I wanted it to work. This is what I wanted:
Simple plug&play. One USB connection to carry high quality audio out from the device while still allowing it to charge. This is the most difficult. On the Nexus 7 it required a special kernel and plus the accessories had to be connected in the right sequence. Not exactly the one action set up I was going for.
The easy way to accomplish this was to use a standard USB charger and then use the headphone jack to send audio to the Aux input of the stereo. Great in theory! However the phones/tablets I have used always allowed alternator whine into the sound. Not ideal either.
Third common way is to use bluetooth audio. My Pioneer deck does support this. But we all know the quality of the sound from this is OK at best. Play some ripping guitar or something melodic and you can really hear the compression (watery, slurred "S"s sound). Not good enough for me.
Now when I had first read about this concept I started accumulating various adapters and parts to play with. First was a Behringer 202 External DAC. Its low cost but had decent reviews. Perfect for my installation. Plus the added benefit of several output format options, so a deck with an optical input could also be used if yours has one. With this I got a simple USB OTG with the Micro USB charger Y-cable. The one that has a standard female USB, the charger connection and the one to the device. Now this whole thing never worked properly. I ended up using the OTG cable with the DAC, but on my home stereo where I could place a Qi Pad under the Nexus (and my S4 before) to charge and the DAC for audio. At least I was using what I spent money on. Just not the way I wanted.
Fast forward to yesterday morning. I have had my Nexus 5 for a few months but had not tried this set up. The fussing with kernels on other devices and units over the years had me giving up. But I figured why not try with the DAC and standard charger connected (they were just sitting there after all). Low and behold it worked! And I mean perfectly! It was a big light had been turned on and the world was beautiful! Then I tried my M8 and it failed......but the Nexus 5 for the win! Oh, and even when connected to the power the DAC turned off when I disconnected the phone. So it shouldn't drain my truck's battery (though I parked on a hill tonight just in case!).
So! Here is my car installation that I was finally able to complete. I have included photos of the installation and the parts I used. It's in a list format that I hope follows the pictures. it will take me a post or three to get it all in! So bear with me.
Ingredients:
Nexus 5 (I am running Liquid Smooth for my ROM, I have not tested it on other ROMs at the time of this post).
External DAC. Like the Behringer 202 I used, but I would assume most would work.
USB OTG and Charging Cable
RCA to 3.5mm headset adapter.
Standard car charger. I have a Belkin 1A one that works like a charm. In theory you could use the USB on the stereo if included, but you may not charge reliably.
Standard USB to Micro USB cable
iBolt xDockPro for the HTC. This is optional, but i like the iBolt and their right angled USB is the right way for the Nexus. Which made the set up cleaner.
Car Home Ultra from the Play Store
So. The first photo shows all the stuff I used (minus the car deck and truck).
Second you will see I am in fact using the HTC Dock
Next is the DAC I used
Followed by the adapter cable
The the RCA adapter
The before picture. The sticky pad for the mount was there cause I was already using my iBolt with just a charger tucked in.
This one you will see I have taken the y-cable and connected it to the iBolt adapter. My dash had the room for this, you may need an extension as the y-cable is really short!
Dash is coming apart!
To be continued (I can only post so many pics at once!

Part Deux!
So the next photo shows my deck's AUX input. Now I bought this unit because it had a rear jack. So connected the headphone plug into the AUX jack.
These next four pictures are just to show which power supply I used and how the USB cable is run up to the y-adapter. Now it would be possible to use your stereos USB for power if equiped. I didn't for two reasons. First, the phone/stereo may think your connecting a flash drive (both unit could be trying to be the "host"). Second the stereo may not put out enough amperage to run both the phone and the connected DAC. So I just went with the separate supply. Plus its easy to disconnect it should I need too.
This is me connecting the DAC. Now I wanted to show this particular step as you can see the power light is NOT lit even when connected to vehicle power.
RCA cable is now connected to the DAC.
The set up all buttoned up!
To be continued.....

Trio!
This post is more about the proof of concept and the Car home Setup. Here it is!
Basically once the hardware was all set (1 & 2) I fired it up, and used Play Music (and others) making sure Bluetooth was NOT paired yet. Sounds AWESOME! Makes a night and day difference! Then I paired it for hands free while making sure the media wasn't connecting. Now went into Car Home Ultra and just set it to launch with the my stereo's bluetooth connection. My only next goal I need to finish is to get an NFC tag to control Bluetooth on the iBolt. Car Home is set to turn WiFi off automatically when its running, but my set up is reliant on BT running all the time (or have me remember to turn it on/off, but defeats my plug'n'play concept).
That's the gist of it. If you would like more details or suggestions please let me know!

So it's not just my Ford Fiesta that sends lots of noise to the charger? I am a little relieved, but it sucks to find out that this is somehow a "standard"...
Nice setup there!

There is a fix. They make something called a "ground loop isolator" that can usually fix the noise generated from you alternator. Here is an example, quick google search brought it up. http://www.amazon.com/PAC-SNI-1-3-5..._sim_pc_3?ie=UTF8&refRID=1FEVW0RPFQ5W3V742E6G
You could put a more temporary/portable set up like mine, wouldn't be hard if your still having issues. Put all the parts together, stuff it all in an old cassette or floppy disk case with a few holes for the cables to stick out of.

Yeah, now the challenge is to find ways to make it work on more devices. It's really unfortunate that the M8 doesn't on Sense based ROMs (I plan on trying a GPE ROM in a few days to see if that makes a difference).
And I may now invest in a proper proclip mount so it's not up on the dash like that. But it works like a hot damn as is for now. Even with LTE on, display always on and streaming audio it charges, though pretty slow. Still. Better than not at all. And I can always turn the screen off if I wanted to give it more juice.

I have my Nexus 5 w/o the case using an iBolt mount I already had and a cheap qi charger and works great.

Nice Setup... I was actually looking for something like this. Thanks for posting

There are a lot of microUSB to USB + aux splitters on amazon for the Samsung Galaxy phones. Would these have worked all the same? Or does the Nexus 5 not have a docking capability that would sense the plug?

For those that don't know BlackBerry sells a blutooth adapter that uses power from the usb charging port on your after market stereo. I use it on mine. This thing is crazy small I hide it in the gap behind my stereo and the reception is good you have around a 10ft radius depending on where you hid your dongle.

Nice I see you have a Colorado. I have a Nexus 7 in mine. I can say that after hours and days of troubleshooting ground noise I could not get rid of it. I had to use a ground loop isolator

modern alternative to nexus 7 with timurs ??

Hi all, Im looking for a modern alternative to the classic Nexus 7 withs Timur's for a new car install. For last couple of years Iv had this. Its been great for it primary use (Spotify) but am just finding it old and tired now, never got round to getting GPS, DAB or all the other things I planned on, mainly its just a bit slow and buggy but I learnt alot about USB connectivity, noise control, power etc.
Being an audio quality freak Iv always used USB audio into a miniDSP. Just wondered if anyone knows what would make a good tablet for a modern replacement? A list of requirement are:-
1) Size . maximum width for my Audi is 211mm, other dimesions are fine. As long as same or bigger than the Nexus.
2) OTG power and data at same time (does this always require rooting?)
3) My first Huwaii experience put me off all other makes of touch screen other than galaxy or iphone. Are other makes just as good?
4) Automatic deep sleep mode when power to the tablet is off. (maybe tasker app?)
5) Operating speed
6) bells and wistles. The nexus has a suprising amount of tech inside for an old device
I was thinking of a pre owned S series galaxy. Just wondered if anyone has has success with a modern in-car tab install??
thanks

Hey @mamba76 wondering if you ever decided on a device? I'm in the same situation, can't seem to find anything that fulfills all the requirements. I have the same idea as you, using USB audio vs BT or analog. I'm thinking USB C is the way to go, newer tech, and hopefully can do data and charging simultaneously? Let us know what you decided on!

Hi, I forgot I started this thread recently. Although the 2013 Nexus 7 with Timur's kernel has served me well over the last 3 or so years Iv been using it, its now just too buggy, slow and hardware is failing. I could have bought a new tab for the money I spent on spares, 2x USB PCBs, just ordered a battery as its given up. Iv been looking for a replacement, probably a Galaxy Tab A, I started researching but got bogged down with unknowns and Im hoping someone on here who's used the Timur's kernel and knows about custom car tablet installs can jump in here and help the car audio customization world move with the times.
For me I suppose Im stuck on- , do I still need to modify a devices kernel to comply with the deep sleep functioning that the Timur's kernel provided? Im pretty sure the audio to USB is not a problem but the audio to USB AND having the device charge at the same time IS. ie. data AND charge. Can anyone confirm that its possible to allow simultaneous data and charge on the Galaxy Tab A??
ps. in my opinion USB audio is the only way to go..

Hi, yes I bought a Lenovo M8 FHD tab (about £150) same width as the nexus so will fit in my car ash without too much hassle. Better spec than the Galaxy, very happy!
