9.2" touchscreen headrest monitor

Assuming the USB input for the touchscreen works with the Athena, this could be a nice in-car dash accessory. It would make GPS/map use really sweet, and phone dialing easier. $195.
Anyone want to test it?
http://www.digital4cheap.com/Shop/Control/Product/fp/SFV/31341/vpid/3917049/vpcsid/0/rid/124129

that would be pretty cool

I keep talking myself out of buying it. At $195 its almost cheap enough to get even if the touchscreen part didn't work with the Athena... but then I would talk myself into getting a mini-PC, and at that point I could have just bought a cheap laptop.

as long as the usb output act's like a standard pc mouse it works. and thats where the problem starts the manual (see the grey box at right side at the bottom) says somthing from 'install the usb drivers first!' so i think there is no luck with these thing. elsewhise a cool idea as an addon in the car.
greet's mad

I figured it would come down to a driver issue for the touchscreen. Still an off-chance it might work out-of-the-box, or that the company offers a WM driver.

for me, i think that would be a bit expensive, i bought a car headrest monitor at Eonon.com, which just need $175USD!

A few Nook HD questions

Hi, I'm thinking of getting a 7" tablet to install in my car, I'm not looking for anything super high spec as I'm literally just going to use it for mapping and playing music. That being said, the nook HD looks like a really good spec for the price..
I've just got a few questions
It doesn't have GPS, but I assume it will work using a bluetooth GPS once I've installed CM10?
I understand it uses a proprietary usb cable, how far does it stick out? Does anyone have a picture of it? This may be me only problem mounting it in dash as I wont be able to find a right angled one!

Yes, you can use a Bluetooth GPS puck. I haven't gotten Google Maps to work with it yet but I have gotten other programs to see it. A 3rd party GPS program should work with it. I'm still planning on testing that theory but to much family stuff has been going on right now to actually do it.
With the connector and the way the cable is wrapped right next to it it sticks out about an inch (just a little under that) from the bottom of the device. I'm pretty sure that to much pressure on that part of the cable will make is useless so you would have to make allowances for it. Also, it needs more power than a normal micro usb cable to actually make it charge. The AC adapter puts out 1 volt at 2 amps.

Got Sygic working today. Had to use this program to get it working though. https://play.google.com/store/apps/...?t=W251bGwsMSwyLDYsImRlLm1vYmlsZWouYnRncHMiXQ..
Other then that seems to work quite well. I should mention that I am on CM10.1.

I got Google maps to work fine with my phone using Bluetooth for gps and Wi-Fi for data.
Have to see up maps to accept debug data and use bluetooth gps programs on both devices

REVIEW AppRadio 2 by Pioneer

Today we’re looking at the AppRadio2 from Pioneer.
Original review with all appropriate links can be found by clicking here.
The AppRadio line is a huge step into the future for in-car audio. Pioneer was first out of the gate with a relatively affordable, practical, and highly functioning 7 inch capacitive touch screen car audio head unit. It's most unique feature and the reason you'll want to read through this review is because the AppRadio 2 can connect to and translate your smartphone's app capabilities into a one of a kind super device on your car's dashboard. You'll be able to use AppRadio optimized versions of some of your favorite apps to listen to music, navigate, find parking, communicate with friends and even check your car's diagnostics with the right accessories attached all on a crisp 7” touchscreen display.
Click here to see a video slideshow of the AppRadio2 in action.
Main advantage: Android and iProduct compatible (some smartphones require adapters iPhone5 and Android), crisp 7” WVGA touchscreen display with multitouch, built in amp (MOSFET 50 W x 4) 2 RCA preouts, subwoofer control, great modern hardware design with high quality materials used, can use your car's existing steering wheel controls, bluetooth audio for phone calls (mic included)
Main concern: no CD/DVD slot, no AUX in, no adjusting display angle, bit of a learning curve, no bluetooth audio for pandora or stored music.
Unique features: built in external GPS means you can turn off your phone's GPS to save battery while connected to AppRadio (turn on “enable mock locations” in your phone's settings)
While it will work with a number or phones, this device was tested exclusively with a Samsung Galaxy Note 2
Someone always has to be brave enough to be the first. Even if a product isn't completely ready for primetime, it's important to release something so that people can become familiar with a new concept. Apple really made their name by being the first extremely simple, yet powerful mp3 player and then smartphone. The early iPhone lacked a lot to be sure, but it did enough well that it changed mobile communication forever. Pioneer has shown that it has the guts that Apple had to start. They took a risk with the AppRadio and it's a great start that has great potential looking forward. Other car audio companies are clearly waiting and looking over Pioneer's shoulder concerning the AppRadio. They waited for Pioneer to make a success of the AppRadio concept and now we are starting to see some copycats emerge built off of ideas learned watching AppRadio. It might work for some of them too, but it's just not a very dignified way to do business and before I even start my real evaluation of the AppRadio 2, I give Pioneer my respect for being brave enough to release such an innovative step forward into uncharted waters.
The AppRadio 2 on it's own is a gorgeous head unit. It's so clean and simple and it's design foreshadows it's function. It floats on your dash as a huge crystal clear glass screen with an almost invisible bezel and a stainless steel “chin” at the bottom that holds the few physical buttons. Volume up/down, a home button, and a menu and back button specifically for Android phones. Pioneer didn't cut corners with materials used, this thing looks and feels like you'd want a piece of the future to look and feel. The AppRadio 2 is first and foremost a blank canvas. It's waiting to be painted with the graphics, sounds, and functionality of your smartphone whether it's an Android or Apple device. While it would be a near perfect product if Pioneer could trust us to control ourselves, we don't do that well unsupervised as drivers. If the AppRadio was a true 1 to 1 mirrored display of our smartphones, we could watch netflix movies and send text messages while driving 90 mph on the freeway. Now you and I might be sensible enough to not abuse the privilege, but plenty of 16 year olds that want to impress their friends in their first cars might not have that same restraint (and they might be driving on the same freeway as you) so try to understand the motivation behind a controlled experience. It's definitely a bit disappointing, but Pioneer offers a very filtered experience of your phone with the AppRadio 2 for now. While some apps can be just about everything they are on your phone, others won't work at all or will display images but not be able to be touch controlled.
Everything begins with a detailed warning to not operate the head unit while driving, fair enough. Commonly called a “nanny” or “nag” screen, a quick click of a button brings you into the AppRadio's main start screen. You'll be greeted by a large modern clock and day of the week indicator to start. Behind that is a wallpaper that can be changed through your smartphone app's menu setting. Below the clock, you'll find 5 icons (radio, iPod, apps, Pandora, and Phone) and with nothing connected to the device, 3 of them (iPod, apps, Pandora) will be grayed out by default. By itself, the AppRadio is simply an FM/AM radio and a speakerphone for hands-free bluetooth calling and that's about it. Connect an iPod and you can play your music, connect a phone through the appropriate cable and you can listen to Pandora or go into AppRadio mode where the real fun starts. A swipe to the right will bring up a second page of options, an expanded settings screen which actually offers a bit to look at. Next an “OFF” button that puts the device in a standby mode that amounts to a screensaver, full screen background and small clock. The last button is a display off button that will let the screen go black if you find a time you need the darkness.
Again, AppRadio2 will work with many different makes and models of smartphone, but it was clearly designed with the iPhone 4/4S in mind. You'll find a very intuitive and polished experience with that phone. Connect the included cable and go. While it can technically be made to work using the iPhone 5 and Android phones, you won't find anywhere near the same out of the box functionality. Whichever phone you use, you'll need to go to your appropriate app store first, Google or Apple, and download at least two apps to get started. The main AppRadio app that is the basis for your phone's connection, and the CarKeyboard app that will also need to be enabled for touchscreen keyboard use while using the AppRadio. The unit looks for these apps and will not function fully without them. Aside from helping your phone communicate with your AppRadio 2, the AppRadio app scans you're already installed programs and tells you which will work with appradio. The apps are the easiest part of getting started with the AppRadio 2 on Android. The part that gets a bit tricky is finding the correct adapter.
If you own one of the Galaxy line of smartphones then you know that Samsung has elected for a single micro USB input on most of their phones. The same port charges and syncs but what if you'd like to output HD video from your powerful phone? MHL, or Mobile High-Definition Link is the answer. MHL allows you to connect a micro USB cord to your phone which is attached to an adapter that turns the signal into an HDMI output that supports up to 1080p HD video and 7.1 surround audio while also charging your device. As simple as they are to use, MHL adapters aren't simple to choose. First and foremost you need to know if you need a 5pin or an 11pin adapter. The Galaxy S3, S4 and Note 2 need 11pin and older galaxy phones need a 5 pin. After that you need to know how much power your phone draws while charging. The MHL adapter needs to be connected to a power source to be able to charge your phone while it converts the video signal. The Galaxy Note 2 draws a very thirsty 2.1 amps of power which is the same as the iPad and most other tablets. The included iPod cable can be disconnected and reveals a full sized female USB port. That USB port outputs 1A charging that is enough for most smartphones including the iPhone. While it will work with some phones, unfortunately it's not enough to keep up with the Note 2. If you were to use a normal 1A car charger (or the AppRadio's included USB charging cable) with this setup everything would still work, but you wouldn't be able to charge your phone. In fact, it would drain battery because of all the work that it's doing. For the Galaxy Note 2 you'll need the following:
-an 11pin MHL adapter
-a microUSB charging cable
-a 2.1A car adapter
-an HDMI cable
These items are easy enough to get, but you need to know what specific pieces you'll need for the best outcome. For the MHL adapter, an abundance of counterfeits have flooded some of the big ecommerce sites, this automatically rules out Amazon and eBay unfortunately. Some copies are identical on the outside and plain garbage on the inside. They will make your setup charge inconsistently or not at all and make your picture signal choppy when connected to the AppRadio 2. Smartphone forums are littered with frustrated people that tried to save a buck on a cheap adapter, you'll see them blaming the head unit but trust me here, there is only one real way to do this. I like a deal as much as anyone, but unfortunately this is a case where you'll need to go to the manufacturer and pay retail. Luckily Samsung is always offering large discounts on it's own accessories up to even 50% off in some promotions. A quick Google search will show you the current deals available. Now that you've collected all of the pieces, you'll need to connect them and get started.

An app called AR liberator made by a brilliant dev who is currently recovering from illness (get well Kyle) makes this one of the most useful pieces of tech I've ever played with.
I don't know if you took the time to read through the whole review or not but at the end there is an "EXTRA TIP" section that hints towards this.

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.

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.

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.

Which OBD2 adapter?

I have old OBD2 v1.5 adapter. Chinese, big one. Which pairs with HU and works well.
I wish to buy new one, that call 'mini'. I know I have to look for v1.5 (as 2.1 is a crap) and with PIC18F25K80 chip.
But I read that even much of these new mini are PIC based, that have some strange Mac address like AA:BB:CC:11:22:33.
Anyone has experience with such adapters? Do they pair and work with Torque on our HUs?
If anyone is using such an 'mini' adapter, please post link to eBay/AliExpress where you purchased it. Will be very grateful (and it may help other people here, too, as many have issues pairing/using crap adapters).

I personally bought https://www.ebay.com/itm/Auto-16-Pi...le-Diagnostic-Adapter-For-elm327/152700822059 and https://www.ebay.com/itm/2017-ELM32...uto-Car-Scanner-Scan-Tool-Cable-/112070132071 so I connected it over USB and only thing I've made is HW MOD to get ACC+ instead BAT+ from OBD2 so that it is powered only when Key is turned on.
Resolved pairing issue with no pairing and all works along with BT and WiFi free for other devices.

Thank you for sharing. I was not considering USB option, but it sounds interesting.
I see you both the 'big' one (same as my old one). And they really work very good.
But I would like to buy some of 'mini' models as my OBD2 port is in such place (under steering wheel and just above brake pedal) that big one is too big and my feet is hitting it while driving. Here is obe model I consider

There are 2 models of these (not colours): old design with 2 PCB boards, and new one with just 1 board. I wonder if anyone has any of these?

:silly: I do not see the problem there as if you checked both links from my post you would see that I use extension cable that do not have issue with connector position. Mine is located right above gas pedal so I could not drive car normally with any OBD Adapter unless I used extension cable.

PIC is programmed micro controller and not actual ELM327 see https://www.elmelectronics.com/products/ics/obd/ and v1.5 nor v2.1 exist officially as they are clones and you should use https://play.google.com/store/apps/details?id=com.applagapp.elm327identifier to test actual model and support.

It is fairly simple MOD:
1. Soldered positive wire of lighter connector that have power only when Ignition is turned on.
2. Bought FLAT cable that I can easily cut the wires like in picture s-l1600.jpg
3. Cut Wire on pin 16 BAT power see ODBII%20Master%20Pinout.jpg
4. Connected wire that goes to OBDII to Positive wire I prepared in step 1
5. Connected OBDII to connector from FLAT CABLE
6. Connected USB to HU SINGLE USB CABLE
7. Tested if all works with Toque
8. Used cable ties to secure all cabling behind dashboard
and now I enjoy the all the diags on HU

Thanks for this info, very helpful, just got Android 8 Eonon 2170, and I've been struggling to pair OBD, Kiwi 3 doesn't show (BLE not supported? Don't know), Tomtom unit won't pair, no name unit seems to work, but, I've thought, why not USB, started searching for USB Android supported, luckily came across your post.
To change BATT to ACC, is that just so it's ' done properly'?
Surely battery drain would be miniscule, or not? I guess makes sense to have it not powered all the time.
Going by your posts, so, some of these units didn't work properly,ECU side or Android side? Thanks again, A

I just looked into factory settings, there is a CANBUS section, currently set to NONE, should that that altered to car maker's CANBUS ?

It is not the problem that it drains a ot but all small drains can pile up so eventually you have a problem. I have park mode security enabled on my dashcam system so it drains some, OBDII can drain a littl, but it is known that in some cases keeps ECU awake that can drain a lot due teh number of sensors it keeps awake also

All was ECU side due the different pinouts see my pics, I have seen in the past several USB -> COM chips that are not supported on Android due the OEM build and specific drivers like some factory that are not recognized on laptop till you install their licensed software (Usually JUNGO Based Drivers).

Only if you got specific cables with canbus decoder (black little box). even then USB OBDII is used to diagnostic and clear codes. I use Toque 1.83 and it works on one unit that v1.52 didn't worked with. Usually ELM v1.5 works better than v2.1

thanks! I have now got USB OBD unit 1.5 (still need splitter/extender), tried yesterday with Torque as well as with Palmer's DashCommand:
it kinda worked - during first trip, 45min, Torque app crashed twice or more, worked after restart, on return trip, DashCommand also choked once or twice, thenm I relaized, as fuel tank level is not reported, unless I run app 100% of the time, fuel consumption won't be correct - and, realsiticall, I need TomTom on the screen more than gauges....
I see there are OBD spliters that 'allow' two or three OBD devices plugged in, wouldn't you know, is it OK to split/use multiple OBDs ?
like, I have TomTom 'Curfer' OBD data logger - just logs 'quality of driving", thoiught to get splitter to log data, AND, if so desire, call gauges on screen ?
thanks for explaing CANBUS!
do you use TPMS tyre pressure units, if so, which ones ? my radio has an app to read such, wonder if it's worth it ?

I have connected my USB OBD. Torque not recognised device. How to check that Scanner is properly installed on android system?
OBD scanner is generic just like this:
https://www.amazon.co.uk/ELM327-USB-Interface-Diagnostic-Scanner/dp/B00IWLLX1Y
BTW I have MTCE with android 8.0 with KLD MCU.

Torque lite ain't work with android/usb, only in bluetooth mode.

I have torque pro so there is no problem there.
Any way problem solved. Bought Bluetooth version.
