How to install an Android head unit in your Audi A4 B6 B7

In this video I will show you how to install an Android Double Din Headunit/Stereo in your Audi A4/S4/RS4 B6/B7
The model used is an Eonon unit with Android 6, 2 gig ram, quad core CPU, GPS, Wifi, USB ports, reverse camera functionality, bluetooth and typical Android functionality.
This guide should be very similar for the various different branded aftermarket Android head unit's out there, although fitting and exact wiring may differ.

Thanks for uploading, looks very nice. Just wish my MK1 Leon had a double din radio cage

[@CraigMansfield]

Really good 👍🏻👍🏻

[@dvdgpsnav]

Nice video, helps a lot for installation. By the way, we can supply Android 7.1 and 8.0 head unit for Audi A4:)

[@yousefkazzazi2889]

Hi great video! I installed the dvd but i have a problem with the radio display and wondering if you can help me fix it? I installed everything and its working great but the only think thats not working is the radio/cd display, do you know wich cable i have to connect for getting the display work again?

[@kelvincaro6451]

What speaker wires did u actually connect for the rears to work

[@ozkrow2386]

He said the rca cables but my radio is missing them I’m checking on what wires run to the rear speakers

[@HelloBiffTV]

with the non-bose syphony 2 on B6's do the rears need a line converter to get full sound. My B7 had very quiet rear speakers and I am wondering if this was the problem when I installed an aftermarket Pioneer media player

[@timothygonzalez8609]

Does this radio work as a replacement for the 6 cd changer Audi symphony radio?

[@airwalk247]

Did you ever run into issues with your code reading on the OBD2 or VAGCOM ? I managed a good install of my android unit but I am trying to connect to my code reader but it will not work. I've heard it could be a k line shorted and we just need to remove the wire. All helpful input is appreciated. Have a great day!

[@danniiliasoff2732]

Did you have problems with Pop sounds Wenn you pressed the Mute botton? Was the system a Full active bose System?

[@corinacazacu6837]

Hello! I have the same car as the one in the video and the same navigation. I did everything you did in the video but the problem is that it doesn't light up for me. I tried all the ways. Can you tell me what I can do to light it ??

[@athanasiossakellarakis954]

On a full amplified bose system is it possible to connect without popping issue?

[@ruipereira4090]

Hi. I am can u tell me how u adjusted the bracket. I have the same problem with the top side.

[@p0werl0ve]

The one thing I am missing on my B6 is steering wheel controls? do you know of an android device that includes a kind of "remote" ? Can you play spotify?

[@victor789012]

Which are the swc1 and swc2 wires in the car ?

[@07kamis28]

does the bt pairs with and iphone?

[@CmdAmras]

Great video! I'm thinking of getting the newest version from eonon with Android 7.1. How reliable is the Eonon stereo you put in yours?

[@CarAndMechanical]

Hey, thanks for the feedback! The headunit has been great so far, I have one issue in that the FM reception is pretty much non-existent, I can't tell if this is a FAKRA issue with head unit, however I stream all my music/radio now anyway. In terms of everyday use I have music playing within 30 seconds of starting the car and with EQ balance it's enhanced the quality of my audio set up (well within the limits of the stock equipment).

[@antonioalmeida7108]

where did u get that steering wheel cover???

[@hadassahviana]

will this fit in a 2009 a4 2.0 cabriolet??

[@aarzy888]

hi ther! grate vid. do you have any idea if this head unit will fit n audi s3 8l?? ty

[@CarAndMechanical]

Thanks, this one wouldn't but there are ones for the 8L that will - if you check out xtrons, pumpkin and maybe eonon they should make one for the A3/MK4 Golf.

[@aarzy888]

ok thanks and thanks for reply

[@BallOut357]

what about Audi a6 quattro 3.2l 05

[@huwgladwin6128]

Does this set up retain the factory sub in the rear shelf working? Love this setup but would want to keep the sub too

[@CarAndMechanical]

Hi, yes for me it does. Both rear speakers and the sub work and are controllable to set levels, the kit has connectors for a 2 variants. My set up is non bose rear amp/rear sub and they work. I use non quadlock plugs but I also got the quadlock plugs. It's key to connect the RCA's and the canbus module.

[@huwgladwin6128]

@@CarAndMechanical excellent I also have the non bose half amped version . Thanks for the speedy reply and informative vid.

[@centrumgsm6963]

@@CarAndMechanical same radio, connect rca like you, and no subwoofer, and real speakers:(

[@user-180-mand90]

What is your honest assessment on sound quality? I've read the sound quality on these Chinese aftermarket Android units isn't even as good as the OEM non-Bose system. Also buzzing issues, rear sub issues, freezing etc.

[@CarAndMechanical]

Honestly works really well - I drove at least 2 hours a day getting to and from work and use the Sat Nav, Internet connectivity and other bits daily and often listen to music/podcasts and watch youtube when parked up and have no complaints. If anything I need to upgrade my stock speakers and amps but everything works and I've had this head unit for 2 years now.

[@knevarez77]

Hey good video! Does this have rcas and antenna cable for an amplifier for subs

[@CarAndMechanical]

Hi, yup rear amp and subs - non bose.

[@knevarez77]

So if I have the bose system it won’t work?

[@janikumlander1822]

Looks good.. does it have bluetooth?

[@CarAndMechanical]

Yep has bluetooth

[@rogersocalbeaches5734]

I have this same unit and on a Audi B6 and the radio would pop when I remove the key. I had to try a Line Out converter, but that lowered the volume. I could hardley hear it. I ended up trying an other Line Out converter, but the same result. I switched to ground loop issoloator, and now its louder, but I still have lots of back ground noise (buzzing in the back gound). now trying to fix that. Did you have all these problems? I have bose radio and am using the factory amp.

[@CarAndMechanical]

Hi, before this were you running stock wiring/amp? I've had this issue in an A3 when I tried to bypass the wiring setup for the rear amp and that was the result. If not what's your stock set up (bose/half amp/ no amp)

[@igsgarage]

I am guessing you needed a booster for the antenna.

[@SuperHuntsman100]

What kind of harness do I need ?

[@ZX10RHO]

Did you use aftermarket wiring harness or did this bolt right on with stock harness ? Also how is the navigation on this unit?

[@CarAndMechanical]

Hey, it came with the wiring, if you check my videos the one before this I do an unboxing showing everything it came with. The Navigation is spot on and I either use offline google maps or wifi tether to a phone to get live traffic maps.

[@ZX10RHO]

CarAndMechanical how do you use offline maps ?

[@CarAndMechanical]

Left hand sidebar in Google Maps, scroll down and go to offline maps, it'll show you an area and you choose how much to download

[@Mrkc47]

Ive bought an android touch screen, everything works on screen, sadly no sound, any ideas please ? Much appreciated indeed .. peace out bro 🤘🏽

[@nikomalik4116]

Hi i try to do the same as you do.. but i recognice that i only have 2 connecters from the car while you have 3.. how can that be.. im confused!

[@CarAndMechanical]

Hi - not sure I'm afraid the 4 Audi's I've have have always had 3.

[@garydavis4228]

I think this is the unit in the car I'm about to check out

[@caiminjacob2798]

Hey how does the soundcloud app work on the head unit? considering getting one of these myself purely for the app

[@CarAndMechanical]

Hi - it pretty much works the same as a phone app, I get data by tethering to my phone.

[@troudyl1]

Hi. can you tell me how connect this radio with rear amplifier from audi? ( active rear speakers and subwoofer). Do you have active rear amplifier in your car? Thank you

[@CarAndMechanical]

At about the 7 minute mark I cover the RCA's - it's a little odd you have to connect them but it's the design. Also you have to move the speaker balance to the rear a bit in the EQ.

[@troudylable]

CarAndMechanical than you for info. yes it is strange because, this radio have 4x45W output for speakers so this makes me confused. ok now i am calm for my harman amplifier.

[@InvisibleYetVisible]

Hi mate, what did you do with the aerial/antenna? One of those is fakra, one of those is DIN. Is there an adapter for this? Where's the video with that?

[@CarAndMechanical]

I pop the antenna adaptor in at 3:08 and it's brief but I show the wire layout at 4:15 - I found the FM reception to be poor and when I looked online it seems to be a mix of different adaptors/boosters but also potentially the Audi aerial itself being broken. I have a very high data allowance so just stream everything tbh as it's better quality.

[@InvisibleYetVisible]

@@CarAndMechanical So mine has a yellow fakra connector and a normal din connector, my point is, how do i make both of these into a single connection. I need some kind of diversity amplifier no?

[@george-alinungureanu1535]

Does any one know where do i get the harness from

[@akyirish5176]

Hi mate, just got my stereo fitted recently, but my stereo doesn’t power off when you switch ignition off and remove keys .. any idea or suggestion?

[@CarAndMechanical]

Did you fit the canbus box? Without it, it doesent know powers off. Also there are two live sources and you could pop the pin and swap them. I heavily suspect it's the canbus box though as you can set stuff like stay on for 2 mins after keys removed

[@shpendidika399]

I bought this same eonon unit, after the fact someone said a aftermarket unit might give the computer chip issues through the CAN . Have you had any issues with your Audi after install?

[@CarAndMechanical]

Tbh it's not missed a beat in over a year. What issues have you head of?

[@shpendidika399]

CarAndMechanical I've just heard that if the aftermarket Navi is not specific to the model of the car it can cause electrical issues through the can bus. That's good to hear you haven't had issues. I'm installing mine today.

[@alexpalomba3274]

What harness is that

[@cenubit]

How work button on handelbar steering? >>

[@AntoVittal]

Does the steering wheel controls work?

[@CarAndMechanical]

Hi, don't have any on my A4 I'm afraid to connect to it.

[@DemonChicken316]

So I am having an issue with it powering on? Could this be due to not connecting the antenna wire? Or, could it be because I have my car coded for an RNS-E? I have a b7/8E with quadlock connection

[@CarAndMechanical]

Make sure the canbus module is plugged in. I had that issue too the first time. The power signal comes over canbus.

[@DemonChicken316]

i definitely do, thanks

[@CarAndMechanical]

That's odd - it is painful but I'd contact Eonon, the power on signal comes over canbus and if you go for a DIY set up it's messy. Double check the wiring diagram against a pinout for the stock head unit. I've known people with RNSE switch to these without hearing of issues - ironically RSNE's tend to sell for a reasonable amount too.

[@gianl0ca101]

CarAndMechanical is there a way I can contact you? I will try to put in a Sony XAV-AX100 in a A4 B6 8H Cabriolet and don’t know if things will work out. Maybe there forums where I can put photos in?

[@mikelamper3587]

Hi - very new to all this, could you give me a link for a compatible head unit please?

[@CarAndMechanical]

Hi Mike, I can but will really recommend you check some bits first against anything I give you - there are a few types of A4 stereos so you need to make sure whatever unit you have will work - I think the type I had works with most. The other thing is Android units are always moving on in tech so power of the CPU's and ram change, back when I got this is was over £200 but think now an equivalent would be under £200. This is the closest I've found www.ebay.co.uk/itm/32GB-2GB-Android-8-0-Head-Unit-Car-Radio-DVD-GPS-SAT-NAV-OBD-DAB-for-Audi-A4-S4/192831195839?hash=item2ce5a28abf:g:F8cAAOSwFCpbqdWS:rk:35:pf:0 There are others for £160 or £300+ I would recommend before purchase checking about the rear amp connection because it's the thing people seem to miss with these units, in the video in my version (hopefully the one linked too) I've used the RCA's which feed the rear speakers. Hopefully this helps.

[@ScootieXP]

Didnt you have problems with the rear speakers not being amplified?

[@CarAndMechanical]

No issues at all, I purchased this particular unit as it was designed to turn on the amp and rear speakers.

[@viktormeltzer1272]

hello!! thanks for the video and I would have a few question if you could help me.. I can't figure out the password for extra settings and developer options.. and how can I put the audi logo on the startup screen? Thanks!

[@russellkirkpatrick9603]

Is there a need to disconnect the battery first?

[@Maakola77]

I did just in case 👍 Takes 30 sec to do so its worth it 😊

[@Fredsss]

what are the solutions for single din cage?

[@CarAndMechanical]

There are a few options but depends what you are after.You can get Single Din adaptors to take a normal stereo but you'll need to research the correct harness (different ones for bose/half amps/full amped). Also I know there are pop out android head units - downside they might cover the coffee cup holder/hazzard switch and esp button (worth googling some install pics). The other option which is more involved is going double din dash conversion and grabbing the bits off a car being broken up - there's a few people who have done it on the B6UK group.

[@cenubit]

I see you car isn't handlebar buttons. How do I connect them?

[@CarAndMechanical]

Unsure as I didn't have them myself but they should be canbus - do might need a menu option on the head unit if they don't just work

[@Zorzgospodo]

My Android won't turn on,Can you help me with wiring?

[@TheMadcell86]

I have bought 2 of these head units and I can’t get them to power on

[@SpookyGhost61]

Can you explain the rear speaker connection you briefly mentioned in the video? I am trying to install the updated version of the same head unit and everything works...except the rear speakers/factory sub. Please help

[@CarAndMechanical]

Yea it's odd you have to connect the RCA's to each other, so on the harnesses there are RCA's that need connecting which output to the rear I think they are this way in can you run an aftrermarket amp. So basically you have the plugs that go in, one has some Yellow and white female plugs and the other the male, connect them.

[@cenubit]

Where to look autoradio for my Audi. How to known it's compatible or no?

[@CarAndMechanical]

I sourced mine from eBay.

[@cenubit]

​@@CarAndMechanical Unfortunately there are too many variants with incomplete spec.

[@danoha2709]

Where do you get those things to take out the radio

[@CarAndMechanical]

They came with the head unit but also have others from ebay for a few pounds.

CarAndMechanical I have the single din radio but I’m thinking of getting the sat nav radio which is double din Car is a A4 b7 2005

[@danoha2709]

Will it fit ?

[@CarAndMechanical]

You'll need to get the double din centre console from another A4 as the normal head unit is bigger then single but much smaller then double.

[@antoniobecerra4490]

Will iPhones work on it ?

[@CarAndMechanical]

As long as Bluetooth works then yup

Lol your car broken a-part and you install android on it , glowboxe is almoust gone haha

Someone help none of these videos have my stereo mine is single din can't find a video or anything about it anywhere I'm getting mega frustrated now also cant just buy harness as shitty audi makes you have to wire up starter wire or what ever it's called if I can't solve this problem I'm actually selling my car lol

So what did u endup doing

[@yarik3950]

But I have Concert One, 1 DIN ...

[@tonygarcia5923]

I do too, just bought a kenwood dmx7704s double din deck and the double din cage to convert it.. wish me luck

[@chasethefeel]

@@tonygarcia5923 how did it go

[@dereklawrence4969]

Did you need to by a wiring harness separately from the head unit to get this to work with all the controls and reverse sensors

[@CarAndMechanical]

My kit came with everything I needed, worth double checking before your specific order but they seem to want to make sure you are good to go.
