Handset for Head Unit

Hey all, not sure if I'm posting this in the right place but meh.
I'm looking to take my cars head unit and throw it in the bin, and replace it with an Android phone, and access music/movies etc from a Wireless External drive.
Here is a basic outline of what I want to do...

I'm very unsure as to what phone I'm going to use. I'd love to use an HTC One X or a Samsung GS3, but they are just too expensive for what I'm doing.
The phone must be able to run a WiFi hotspot, have a good quality screen, preferably run Android 4+, and most of all not be too expensive.
Any justified suggestions would be greatly appreciated!
Thanks all :good:

What do you plan on using to drive the speakers once the head unit is out of the picture?

Let's do this the proper way here. And by do this proper here I am stating this for my self. That statement as odd as it sounds is not meant for you. Lol!
I am a car electronics installer. I have been installing car audio, alarms and remote starters for 16 years now. And I feel very inclined to help you make the best choice as to how to go about this. So I am going to as several questions.

That's fantastic, lets use some of your juicy experience
Haven't thought too much into the AMP yet, what are your thoughts here, do you have any recommendations or suggestions?

So, what year, make and model of vehicle are you doing this in?
How much do you know about car audio?
What amp/amps, speakers will you be using?
What will you be using for volume control?
What is the reason for ditching the head unit?

Just so you know. My cell keeps dropping its data connection like I this going out of style. And it is getting late here. But what I would like is s much detailed information about what you are doing. That way when I get back here later I can throw my two cents in to the mix with a proper understanding of things. Any way if others get here and help you out before I am able to get back then good luck. If not, I look forward to helping you out.

How much do you know about car audio? First project, have a back ground in electronics, IT Technician by trade.
What amp/amps, speakers will you be using? Unsure yet, haven't thought too much about the AMP, reckon I will ditch my stocko car speakers though.
What will you be using for volume control? Good question, was originally thinking the handset, but it will probably not suffice.
What is the reason for ditching the head unit? It's the stock Subaru one, it's broken, I hate CD's, BT Head Unit was an option, but I'd rather be able to use an external drive as my data source.

So, my suggestion for volume actually, I should say gain control. Should be of a hardware nature. Now, my honest suggestion, would be to purchase a new head unit. And use the headphone jack out of the device you will be using. That way you can keep the Bluetooth still. And you wouldn't necessarily have to buy an amp or amps. Unless you want massively loud music. In that case, go for the gold. But I say use a head unit because even though you don't like CD's and what not. It is always better to have a backup plan if the original one fails at any time. And a double backup plan is even better. But that would involve having a head unit and at least one amp. I will make a drawing of what I am talking about tomorrow. Not sure how far you want to take this. But maybe even an EQ installed into the mix would be a good idea. Especially if you are adamant about not using a head unit. Any way, I have to go to sleep. I am exhausted.
One other thing, did you ever think about using, say an SSD drive through an OTG cable? I'm not sure of how to use a drive as a music storage device and go through an OTG cable. But depending on the device you decide to use. That could be a viable option so that you could use a Bluetooth head unit. Any way, I am finally off.

[Q] Streaming bluetooth in the car with N4

For those who do not have BT built-in your car, what do you use with your N4? I'm currently looking at the following 2 devices. Any other suggestions would be helpful

Monoprice Bluetooth Music Receiver
http://www.monoprice.com/products/p...=10827&cs_id=1082704&p_id=7364&seq=1&format=2

I use jabra street 2. Works perfectly. Also useful as bluetooth headphones.

I wouldn't suggest the monoprice one. I heard that it doesn't auto connect when you start the car.
Look into the Blackberry Music Gateway. I just ordered one and it should be arriving tomorrow. It autoconnects with no problems.
I'm hoping to use this in conjunction with NFC to make everything automated.

I use the XtremeMac Incharge bluetooth. It works great and have used it with multiple phones and never had a problem syncing

I'm using this: http://dx.com/p/bluetooth-v2-0-edr-audio-receiver-w-3-5mm-audio-jack-for-iphone-4s-more-black-120198.
It's worked flawlessly so far. I've used it for over a year with my GNex and now my N4. I've never had to reconnect it after the first pairing and it's good to go as soon as I start the car. The only negative would be the shipping time from DX. It usually takes about a month for my items to arrive, but the low prices make up for the inconvenience.

I've Bluetooth in my fiesta but it won't pair with my N4! Grrrr

HTC Stereo Clip A100
http://www.amazon.com/StereoClip-A1...qid=1360871851&sr=8-1&keywords=htc+stereoclip
Bought this from Sprint.com for around 70 bux last year. Great investment. Small in profile and works great! Music is clear and works every time.

I use the "GOGroove Smartmini aux"
It's cheap, and works great. Only downside is the annoying bright flashing blue light when it's paired. Mine is out of the way though so its not very noticible to me when driving.

Do you have another phone paired? Sync can only pair with one device at once and it was tricky figuring out how to drop the old one my first try. If that fails is there an update avail for your sync? Ford posts the updates and instructions to load using a flash drive on their website.

All good suggestions.. I like the GoGroove because I don't need a separate charger and it doesn't take up space in my storage console. I'll have to add the XtremeMac and BB Gateway to the list as well.
Funny thing is I used to use the Nexus One desktop dock to stream from my N1 in the car.

As someone linked to this seems tempting:
http://dx.com/p/bluetooth-v2-0-edr-audio-receiver-w-3-5mm-audio-jack-for-iphone-4s-more-black-120198
It's definitely gotta be the cheapest, and while only 2 reviews one does say it autoconnects. Sure hope it does.
What would you guys say is the best that:
- Autoconnects
- Has microphone support for calls (that doesn't COMPLETELY suck?)
I guess any bluetooth receive could be charged without issue... though I guess it's also nice to have one that is sort of "designed" to be used charged, so no real on/off type of thing...

With GoGroove, do you need to "turn it on" each time you start the car?

Yes my iphone was synced. Any idea how to unpaired the device? I I've since sold the iphone

Last week I was in a rental Chevy with full BT integration. That made me realize just how nice it was, and how crappy my hacked 3.5mm input + Belkin BT in my older Saab really was.
So I broke down, called Crutchfield and ordered a Kenwood Excelon KDC-X796 head unit with full BT, USB, Pandora integration, HD radio, CD, etc. It arrived today and I had it installed in about an hour and a half, including soldering up the wiring harness. $189 well spent, fun new tech and sounds SO much better than the old stock head unit that it feels like I have a new car! Excellent, proper hands free calling with an external mike even. A bit more finish work to do when some other bits arrive on Tuesday.
There are cheaper similar options, even under $100, that lose the HD radio and CD player. I really wanted the HD radio, though who listens to CDs now?
Four hour round trip tomorrow to see my sisters and a couple of my nieces, probably streaming Spotify the whole way, with Google Nav running and some calls thrown in for good measure. The full workout.
Of course, the Crutchfield rep sold me a new set of door speakers too. "These are good, and they're on sale!" I'll get to those later. Then I suspect I'll want to replace the rear speakers. Then the dash speakers! LOL

yeah. you have to yell at the lady.
I bought my car used so it was the first thing I had to do was unsync the previous owners' phone.

I've been using the GROM-USB2 with a bluetooth adapter for about a year with multiple phones with no problems. It integrates with many factory stereos. In my car, I can use the steering wheel controls to skip tracks, and the seek buttons on the head unit to activate voice dialing and hang up calls. It also plays the navigation audio over the stereo speakers. It's a bit more than the ones you are looking at (about $130 with the bluetooth option), and installation is a bit more involved, but I'm really happy with it.

Just another Nexus 7 In-Dash install. Plus wireless charging Nexus 5 in vehicle

Hi all,
I finished my Nexus 7 tablet car install and just wanted to show you guys the finished product. Not sure if this is the right place to post.
I also mounted a Qi Charger for wireless charging by just dropping my phone in the Sunglass Holder area of the car.
The way it works is, I turn on the car, Tablet turns on, connects to my Nexus 5 Hotspot and to my bluetooth adapter. I am able to control the volume through the steering wheel controls. When I turn off the car, Tablet turns off (thanks to the command, see below). This way it ensures the tablet battery is always Full.
Here are some pics and instructions of my setup. Thanks!
PARTS
USB Car Charger
Metra Double Din Kit
Miccus Mini-Jax RX
NEXUS 7 SETUP
Root the tablet
Install Tasker to be able to:
- Power off tablet when not charging (tablet turns off when car is off)
- Use command - fastboot oem off-mode-charge 0 - (tablet turns on when car is on)
- Keep tablet awake
- Enable Wifi, Bluetooth
- Also created a custom Boot Animation when the tablet is powering on. You can see it in the video below.
Install Nova launcher to remove things like the Dock and have more control of the interface of your tablet.
NEXUS 5 SETUP
All I did was install Tasker and set it up to turn on Mobile Hotspot whenever the phone is Wireless charging. That way I just drop it in the sunglass holder and I can start tethering to the tablet.

PS. Here is an older video of the setup. This is when I had the Head unit mounted under the driver seat which I did not like. I removed the faceplate off the Head Unit and was able to move the head unit in back of the tablet. This turned out to be a much cleaner install this way.

One quick question, does the tablet get heated when ON for a long time? I have tried to use my mobile phone for navigation, but, the temperature becomes so high that they device takes time to respond (of course, I noticed this in the summer heat of India when the mobile was mounted using a windshield-mount)

Anyway, still...why do that to an E90. No answer needed. Just another BMW driving douche's opinion. F10 owner here.

^ You're right about one thing - the douche part.
Nice install OP. Working on the same setup for my '06 330i. I plan to wire it into the AUX under the armrest vs. listening over bluetooth. I have not had a good experience with the audio quality over bluetooth.
Would appreciate more details on how you removed the faceplate and secured the head unit behind the N7. Did the head unit retain all functionality? I read that you can still use your steering wheel controls, but I'm wondering if the BMW bluetooth for calls still works with the faceplace off. Not really ideal though, because if there's a need to pair the phone again (or a new phone), you'd have to put everything back together. I may shoot for the glovebox with BMW head unit. Doing anything aftermarket is a real nightmare with this Logic 7/MOST/fiber setup.
Also, is the wireless charger able to keep up and give you a positive charge while using the phone as a hotspot?

Forget it.

Awesome use of n7. Brilliant use of tasker and fastboot command.

Nexus 7 Dash install

Couple of weeks ago my Pioneer DEH-3500UI head unit and about 32gb worth of SD cards got jacked, so I figured it would be the perfect time to install a Dash Tablet, and also make it theft proof by doing a completely removable design.
So, lets just go through some of the items of this build.
The Vehicle is a 1992 Chevy S10 Tahoe, that's got about $7,000 worth of upgrades already (I'll post a link for those if anyone is interested)
I'll be using a Nexus 7 LTE tablet on T-mobile since 5gb data is only $10 for me.
for augmenting the truck I'll be using a Scantool SX OBD-II adapter with Torque pro, at a later time I'll be integrating an amp to power my existing Pioneer A-series speakers, And possibly a backup camera at a later date.
The mount will consist of a RAM cradle, mounted permanently to a plate that will function as a mount surface and a cover for the headunit.....hole.
I'll also be mounting Two RCA jacks and USB ports on the plate so if I decide to remove the tablet completely I can also easily remove the external wires mounted to the RAM cradle, which I'll mount a Micro USB plug and a 3.5mm Jack to the cradle that will connect when the cradle is closed with the tablet in it.
I don't have any pictures yet, but I'll get some posted up in a day or two, Tablet and the main install parts SHOULD be here Monday.
And for those interested, Here is a link that explains why there is so much $$$ and WHY I'm using an OBD-II Adapter on a 1992 vehicle :silly:
I'm a link

So I read this and my first thought was "Over $7 grand in a truck worth $700? Dude has way more money than brains." Out of curiosity, I followed the link and read all 23 pages of that thread, and now I just think you've got more passion than brains...or you're a glutton for punishment. Either way, I salute your dedication. I've got a laundry list of things I want to do to my 2008 Envoy Denali (getting Android in there being one of the main ones), but I always end up putting them off. So good on you for actually following through on some of your crazy ideas. I've subscribed to this thread and I'm anxiously awaiting how this will turn out for you.

Quite honestly though that thing started life out just to impress someone, what it's turned into is a money pit and my baby.
I mean it's like a Envoy XL and a Syclone had a baby.
Putting a tablet or something would be much easier for a stock looking install in your vehicle since it's a double dinn. Mights actually be pre-made bezels.

I'm using Lollipop 5.0.2 + ElementalX 3 Kernel which has OTG charging, S2W and DT2W
Other than that I'll just be using the standard Lollipop UI, may look into some UI mods to add softkeys for volume and what not, but for a non integrated headunit it should be fine without a fancy UI overlay.

DIY 2DIN project

After reading some reviews, I decided I could piece together a head unit that would give me a solid hardware base.
Hardware list:
Odroid XU4
Lilliput 669gl
Bybyte 2DIN case
Sure Electronics 4X100 amplifier
Various Dongles for BT, GPS, Radio
Mini-box Dc-Dc USB PSU
There are three things I need to resolve:
1) Audio. The screen will be fed HDMI. Am I better served to use the hdmi for an audio source, or a USB - DAC?
2) FM radio. I downloaded SDR touch. The software is interesting, but no-where near vehicle operator friendly. I'm having trouble finding an automotive style alternative.
3) The USB Dc-Dc PSU has "Automotive" mode. That leaves me needing away to trigger shutdown from the XU4. I've only researched this lightly, but I was hoping for a suggestion on how to go about this.
Any input is appreciated. I hope to have the screen and case in the next few weeks.

Well, you beat me to it. I have had intentions of creating a DIY thread for a while. I was waiting to make a little progress before posting, but we can use this as a collaboration/discussion area, and hopefully it will develop into some software solutions.
I too have been meandering down this road for a while. After some pretty active work on the Newsmy NU/NR units, I finally reached a breaking point. My Unit is suffering pretty constant reboot/lockups and I'm no longer interested in compromising on my goals.
I've ordered some similar components and am hoping to start bench-testing some stuff soon. My list:
Inforce6450 SBC (Qualcomm Snapdragon 805)
Raspberry Pi 3 (To be replaced by the Inforce when it arrives)
Eleduino 10.1 1080p LCD/Capacitive.
Cheap NANO-SDR
for a case I'll scavenge one of the several Chinese headunits I have around here.
Power-supply - hadn't ordered one yet - I like your suggestion - will investigate.
So some thoughts on your questions:
1) For your/our purposes, I would look to a USB-DAC. Especially if you can offload the audio processing. I'm a little worried about the CPU/horsepower of some of these boards (esp my RPI 3 - which is I why I ordered the Inforce)
2) We will write our own radio front end. Shouldn't be difficult. While SDR touch is not open source, there are a lot of open source examples that should be helpful. Could even use the Newsmy radio source as a starting point (although it's not terribly pretty either)
3) Not sure about the communication abilities of that PSU, but I had planned on using the GPIO's of the SBC to perform some basic signaling (like tripping a relay for USB power, sensing ACC vs 12V, etc.)
Looking forward to seeing other's approach.

Awesome! Be warned that I'm a complete and total novice. I like to repurpose things more so than create my own solutions. I hadn't even thought about the GPIO to signal shutdown. I will start researching this.
I'm going to be pushing the limit on what I can fit in a case I think. I was looking for a DAC without an enclosure but got side tracked. I was looking at the twisted pear products briefly.
Here is the PSU:

Looks like I might have found something worth looking in to

Project got tabled until this spring. I had a bad experience with mobile computing solutions and haven't had time to get back on the horse.
Something smart goes here

Have also been planning a build for a while to go into my HDJ79R landcruiser.
H/W;
CNC machined aluminium face plate
UDOO QUAD - i.MX 6 Cortex-A9 Quad core 1GHz
ChalkElec 7" open frame universal HDMI LCD with capacitive multi-touch
BT Dongle
Columbus V-800 usb GPS
64gb SSD
uSDC20D shutdown controller
TDA7850 4*50W Amplifier (only need 2 channels but seems 2CH don't exist)
Switches + Rotary encoders programmed to act as USB HID Keyboard via ATmega32U4
Software side is definately where I think the difficulty will lie - getting a decent interface for interaction
I want to run android 6 or 7
# android as bluetooth client - HFP client and A2DP sink support via recompile with profile_supported_hfpclient and profile_supported_a2dp_sink set to true in packages/apps/Bluetooth/res/values/config.xml)
# re-launching music at startup and playing the last track
# Fast Startup!
# Dim Screen / Dark Mode on Illumination signal triggered (Headlights on)

I had mine up and running on the bench and my 2nd XU4 has suffered a failure.
I jumped on a 4 channel 100w from parts express and a Behringer USB DAC. I also bought and modified a Ford AM FM head unit to start packaging everything.

I've been wanting to do something like this as well. However I've thought about using a sony radio, with app remote functionality. Gives decent sound quality, radio etc all controlled through an android front end.

Can you link what you are talking about?

That'll control the head unit, so single din could be mounted behind the tablet install. There are several compatible head units, with DAB radio etc

Anyone happen to have a link to a place to buy the stereo chassis that all the Chinese builders are using? I would really like to have one of the ones that looks like a Ford.
