I have the Sony RM-X11S installed in my car now, but it still isn't fully operational. Three of the buttons are a little wonky, but adding a resistor may fix two of them. Other than that, it is very easy to get up and running. The only wire that really matters is the 3.5mm male audio jack. You can cut the 3.5mm jack end off the wire and use the 3 interior wires or you can get a 3.5mm extension cable(it comes with one) and splice into it.

Currently, I have the main wire connected to KEY1, the secondary wire connected to KEY2, and ground into KEY-GND. The three buttons with issues are [Mode] [-GP/ALBM] and [+GP/ALBM]. I think if I put the resistor in KEY2, [-GP/ALBM] and [+GP/ALBM] may work. ATM, they are muddled with the [track forward] and [track back] buttons; as well as each other. So if I press [-GP/ALBM] , it also sends the [track back] signal and the [+GP/ALBM] signal. The [mode] key is dead. I need my car operational for some traveling, so it wont get changed for a while.

I took a seek switch out of another head unit. You can turn it to the left or the right and it always snaps back to the middle. I'm assuming middle is off and left is one voltage and right is another. It has three leads on it. How do you think I could wire this up to work as volume?

Actually it has 5 leads but I think only the bottom 3 are used. Here are some pics.
[Android Head-Units] supremekizzle:
So, curiosity took the better of me and I tore my switch apart. Looks like the way it works is leads 1 and 3 are power in and 2 is ground or vice versa, 1 and 3 ground and 2 power. There is a disc with contacts that, when turned one way will connect 1 and 2 and turned the other, will connect 3 and 2. Like this [IMG="switch"]https://docs.google.com/file/d/0B9X5Kpe-7UfaTFhMa0lYR0syS0E/edit?usp=docslist_api[/IMG]

Now, knowing that, would a circuit like so enable steering wheel controls via this knob in a resistive nature?

[Android Head-Units] 1WindManic:
This should work exactly as expected.
[Android Head-Units] supremekizzle:
Great. That's good to hear. Are you electronically inclined? Two questions: 1. What value resistors should be utilized? And B. How would this be hooked into HU? Just ordered my unit tonight so I won't have it for a week, but I want everything prepped and ready for when it arrives so I'm not dinking around with stuff when my dash is completely pulled out. (Doing some custom lighting at time of installation)

Thanks

Anyone experience with a HUAWEI E3531 3G internet dongel ?

I bought one and it works perfectly fine with my laptop, plug & play, no registration, no installation, no nothing.. But with my HU it keeps on trying to connect.. Anyone any idea what it might be ?:confused::(
[Android Head-Units] 1WindManic:
Yes I'm electronically inclined. 1.) I think, there is an app to map buttons, so you should be good with any values (for ex. 200 for volume down and 500 for up.)
[Android Head-Units] guap:
plese keep me informed, I'm planning to install it on golf VI, passatCC and maybe on my scirocco itself :)
[Android Head-Units] 1WindManic:
Just to introduce myself, I'm long time lurker from hui-fei thread. I was looking for audio replacement in my Mercedes ML W164, and found this thread. Bought NU3001 and preparing my unit and wiring harnesses.
[Android Head-Units] Zaphod-Beeblebrox:
Looks nice, but I'll bet you could have fit the NU5002 in there :)
[Android Head-Units] 1WindManic:
8" is indeed very nice, no buttons... doable, it fits, but I found no fascia for it, and this one i have for 7" is perfect by design /screen is slightly bigger than hole for 2din and perfectly fits, without a gap/.
[Android Head-Units] toteki:
Wow, looks so much nicer without the buttons on the left.. If only I know before.. Haha

MCU v40

Greeting all, my first post here.

I found MCU v40 at Newsmy forum. I PM-ed alaninsitges for the link, hope he can publish it.

Anybody here want to try? My NU3001 is still in China.
[Android Head-Units] e.sjolund:
I think those two resistive values are way to close together. Look up the schematic for the sony RM-X2S or simular and you can see that it uses a 2k2 resistor between every "command".

Just thinking out loud;

I would imagine you could use an arduino and a rotary encoder to control the volume etc. You could set the arduino to send out an analog signal/use a resisive devider to simulate the votlage. (just have to messure the voltage from the SWC after a resistor, for instant a 2k2)??

- in other words, send a voltage that is proportional to what the SWC would have gained if it had a resistor? plausable? yes/ no?
[Android Head-Units] 1WindManic:
it varies from manufacturer to manufacturer, he should try.

best way is to use encoder, but this needs more skills,
[Android Head-Units] alaninsitges:
And here is MCU40. Thanks to limbug for finding this and letting me know!

http://www.newsmy-car.com/bbs/forum.php?mod=viewthread&tid=32227&extra=page=1
[Android Head-Units] e.sjolund:
That's true. I got cought up with Sonys remotes.

An encoder + microcontroler is the way to go, but like you said, it requires more skills. It might be plausable to use a decoder and simply add a couple of diodes + resistors. That way the signal will only transmitt if the polarity of the diode is correctly... but again, might not work bc of the internal voltage drop and the time the encoder is tured on ??
[Android Head-Units] usafle:
Ill wait for someone else to try this one out. Who knows what will happen when this version is applied. Lol

Seems like the upgrades are becoming downgrades lately.
[Android Head-Units] Bokomaru:
Downloaded and attached here. No release notes inside. I haven't tested it yet
[Android Head-Units] Zaphod-Beeblebrox:
1.1.5/1.1.6 and 160 DPI

Is anyone running the latest 1.1.5 or 1.1.6 (or any version at 160dpi)??

What are your thoughts on the resolution/scale?
[Android Head-Units] kwalsh24:
I too am curious on people's opinion on 1.1.5 & 1.1.6. Anything updated ? Anything added or fixed ?
[Android Head-Units] -=Jeff=-:
From past experience with a tablet in the car, the smaller the icons/ text the harder to read at a quick glance.. That said I think about 215 is good for in the car..

Is your ROM set for that? I have everything set up how I like it at the moment or I would give yours a shot.. I really need to get a second box.
[Android Head-Units] blacklistedcard:
+1
[Android Head-Units] limbug:
Me too! Upgrading the MCU is very risky. If something bad happen, you need to return the unit to Newsmy.

I have a JTAG programmer, capable to read (if not protected) or write the flash memory inside STM32F103VC, but don't know how to use it to upgrade/restore the MCU.
[Android Head-Units] kararom:
MCU v40 working good
[Android Head-Units] Zaxela:
There are some problems in NU3001 with ROM 1.1.5 and MCU 37.

There are problem with turn on of device and standby problems too.
[Android Head-Units] lu_ramen:
Can I trust you? Your image says "DANGER" :D
[Android Head-Units] kararom:
In picture :)
[Android Head-Units] Black6spdZ:
can you test the custom standby times? I wonder if they got that working completely yet
[Android Head-Units] Bokomaru:
It was working with their 1.0.5 code because it would properly send the serial command to set it. Hopefully v40 has a default value set in it so even older android code will work.

It'll be irrelevant soon though since the community version code has support for that. Once my rebuild is complete I'll upload a version. My builds take forever to complete though so it might not be until late tonight, someday I'll upgrade my computer.
[Android Head-Units] Black6spdZ:
I'm not quite sure what the problem is, but my USB based OBD2 cable "OBDLink SX" pauses every few seconds for several seconds and repeats.. so the average update rate is VERY slow. Same result with both Torque and OBDLink app. It worked better on my old slower AN-21U stereo. Not sure why this would be the case with a much faster unit. Any ideas?
[Android Head-Units] supremekizzle:
A lot of what you guys are saying is way over my head, but what I can gather from context is you can have a board that simulates, or rather, puts out a voltage or resistance that you specify? I think I've heard about arduino before. They're kinda like hobbyist circuits right? Like raspberry pi? You don't have to get into an explanation, like I said the ONLY hardware button I require is for volume and if my knob works I'll be happy to use that mounted to my dash. Quick question though, is it preferable to use leads 1 and 3 as power with the resistors hooked to them or 1 and 3 for ground with risitors to them? AND how do I incorporate this into the head unit? Thanks for this brilliant community.
[Android Head-Units] lu_ramen:
Confirmed. MCU v40 is working :good:

Don't get me wrong, you can build that gizmo but need more components and some coding is needed. I'm using Microchip's PICs for that.
[Android Head-Units] supremekizzle:
I think I'm OK with my single knob mounted to my radio bezel. Did you see my other two questions? Does it matter which leads are used for power/ground? What wires on the HU does power and ground go to? Thanks for your help
[Android Head-Units] Summer-Newsmy:
Could you send us a after-installation picture?
[Android Head-Units] pppeterrr:
touchscreen not responsive

Sometimes the screen isnt responding

I think it has tot do with the shutdown procedure.

When i turn the ignition off, it looks like a total

Power cut and direct shutdown. I can imagine that

This might be the problem.

Now i use the shutdown menu, which actually reboots

The hu. This seems to work. When screen goes off

I turn the ignition off

But does it suppose to reboot, since this is a strange work around

How do you guys power off the hu?
[Android Head-Units] 1WindManic:
Ok, but now I don't know what type of knob. You have 5pin encoder and the other one, with resistors hand drawed. If the second one, then GND middle pin goes to KEY GND and pin 1 and pin2 goes to wheel key1 or wheel key2 /I also tried, that the resistor has different values measured between WHEEL KEY1 - KEY GND and WHEEL KEY2 - KEY GND /220ohm resistor KEY1 - value 262623, KEY2 value 328165/

Can anyone confirm if Tuatara's 1.1.4.2 ROM is working with MCU 40 ?

Internal WiFi

How stable/good is the internal WiFi adapter?

I am going to be using EE Buzzard 2 4G dongle for the car's WiFi hotspot but wondered if it would be worth getting a USB WiFi dongle too. I'll also be using the Buzzard 2 to power a USB hub too to charge my phone, etc. Any recommendations on a USB powered hub?

I'll also be setting up this BW-Wireless-Transmitter-Receiver-Reversing-Black for reversing camera (cannot put in links yet :()

Not too bothered at this moment in time re Radio/RDS as will be using Radio Apps (AM/FM can be a bit iffy during my extended commutes....)
[Android Head-Units] toologic:
Hi all,

My experience MCU upgrade to version 40:

- 1 day of testing (today)

- Not running standby mode (set to 2 hours)

- Each time a full boot android

- After booting the radio automatically starts

The update process (from v35) went without error. After rebooting the system and the first run the application MCU - an error has occurred. Further, the error does not appear. All settings in the configuration files (/ shared-prefs) saved sucessfully
[Android Head-Units] nestortoledo:
A running on 1.1.5 or 1.1.4??
[Android Head-Units] Black6spdZ:
this may be a generic android issue and not actually something with the CarPad, but to simplify tethering I started using internet over Bluetooth which may have bandwidth limitations but works fine for maps and internet radio. Even though it pairs automatically with my phone when I get in my vehicle why do I have to go check the box to use internet every time? This would be a much more elegant solution than having to setup a profile on my phone that turns on WiFi tethering after the Bluetooth pairs.. and probably much better on my phone's battery life as well.

Well after doing a bit of reading I answered my own questions, yes battery life is improved with BT tether and no, it won't save the option by design but there are some apps out there that can make it automatic, Here's one I'm going to try later when I have a free minute http://xdaforums.com/showthread.php?t=1543666
[Android Head-Units] Bokomaru:
Definitely a generic issue. I recommend the Tasker app for this and a ton of other stuff, you can do some pretty awesome stuff with it.
[Android Head-Units] Black6spdZ:
Thanks I'll give it a try
[Android Head-Units] Duck Dodgers:
Is it the Tasker by Crafty Apps EU?
[Android Head-Units] topcatbv:
Tested today v40 (v39 previous) with 1.1.5, all ok, my problem with rebooting all the time when ignition on has resolved.
[Android Head-Units] supremekizzle:
That's what the second knob is! A rotory encoder. I thought it was a potentiometer but it didn't make sense that it could scroll infinitely. I don't think the encoder can be used for this application without a processor of some sort in between it and the HU, right? Think I'll use the 3 lead momentary knob. What are you saying in the later half of your post? Please remember, this is brand new to me. I don't understand the values you listed and how it's applicable. I was just going to ground to key ground middle lead, then split the wheel key positive to each if the outside leads with a different resistor to each one. That way when I turn the knob one way it will complete the circuit through one resistor and turn the other way with complete it with the other one. Make sense?
[Android Head-Units] Bokomaru:
Yep. I use it on all of my android devices. It costs a couple of bucks, but there is a trial version.

I get about 19Mbps out in my garage, my router is in my basement utility room which is next to the garage. When I'm testing in my computer room I get around 32MBps and that is a couple rooms away.
[Android Head-Units] Firewater Burns:
For those using locally stored music, what player app are yall using?

Currently, I am using Player Pro, but is has an issue with songs on the 64GB USB flash drive. When the HU goes into the 2 hour standby mode, the USB will power off after a couple min or so. This causes Player Pro to lose track of the music. When the car is started again, it has to rescan the 4000 song library.
[Android Head-Units] Bokomaru:
I've noticed the USB go away as well and it's something we can fix. Personally I'd prefer just to have the USB stay on as long as the android box is on but I think a configurable option is going to be the best route to keep everyone happy.
[Android Head-Units] janla:
Dear Summer,

Yes, as I am still interested as PM-ed you earlier.

btw.

Can you confirm or deny that Newsmy plans in nearest future (say 6 months) to release new hardware version of Android Box?

If so, I would consider to wait for hardware upgrade option rather to avoid having two obsolete boxes.

CarpadCE ROM version 1.1.6b1

I've uploaded a new build of a rom based on the github code. This is not my rom, it is a collaboration of everyone in the community that has contributed to the code base that is on github.

I've named the rom CarpadCE (Community Edition) and set the version as 1.1.6b1.

This has most of the recent changes merged in, though the radio code has not been touched (waiting for [MENTION=2190016]Zaphod-Beeblebrox[/MENTION] to have some free time)

I figured out the last bit of the TWRP code to make TWRP an ideal default. From now on I suspect most people will want to use recovery for updates. Using recovery to update you won't lose your settings unless you intentionally wipe them.

New features:

Rooted by default with SuperSU

USB flash drive accessible from TWRP

Ability to set standby time

Files are uploaded to a google drive here

carpadce-1.1.6b1.img is an image that can be pushed with the RKBatchTool

carpadce-1.1.6b1.zip can be updated via recovery

More things to come in the future. Thanks to everyone that has contributed!

Edit: there is an issue with this release and the filesystem keeping some apps from working. Also the name has changed and the official community release name will be: xdAuto
[Android Head-Units] Psy87:
Do we need MCU 40 for that? Could you attach the corresponding link?
[Android Head-Units] 1WindManic:
Hi, as I said before, rotary encoder needs some processor to decode gray code form encoder and to translate it to something other, so no simple solution for you.

Here I attached wiring diagram, with momentary rocker switch, no matter if it is knob, the principle is all the same. It should be self explatantory to you.
[Android Head-Units] supremekizzle:
You rock. Thank you. A picture is worth a thousand posts.
[Android Head-Units] Black6spdZ:
good work! really glad you made a CW recovery zip, will also keep from getting recovery.img flashed each time as well.. now all we need is that optimized kernel from blacklisted and these units will be top of the line!
[Android Head-Units] janla:
Many Thanks!

One question:

What is the userdata partition size set in build.prop of this rom?

I am on Tuatara 1.1.4.3 with repartitioned userdata up to 3G (from stock 1G)

I intend to update by cwm recovery without wipe, so i assume this may be done only when CarpadCE is also repartitioned to 3G.

Otherwise, userdata need to be reformated back to 1G, that means wipe of all data.

Is this correct?

Also if there is actually 3G userdata set in the build.prop - is it possible to keep data by the people coming from 1G roms (stock)?
[Android Head-Units] spoks:
I have about 60GB music on local SD card. There were problems with Player Pro for me, like every time scanning for all songs and audio glitches (on Tuatara ROM).

Now I am on XDAuto rom and using PowerAmp. Audio glitches happens very rarely, but song scanning every time device boots up still exist - have to wait some time to be able to play music.
[Android Head-Units] Psy87:
You can stop media indexing. After that, no more glitches or someting like that.

If you update your stick with new music, you can index it manually with some apps.

I used Autorun Manager to stop and use poweramp for playing and indexing.
[Android Head-Units] x5nder:
GoneMad Music Player (GMMP) is lightning fast in scanning music files + has ability to only rescan manually, so it doesn't scan/delete upon reboot or restart :)
[Android Head-Units] Black6spdZ:
just flashed 1.1.6b1 "lightened up a bit to 205MB" and mcu v40.. over 1.1.4.3 and mcu v35. No data loss, settings all retained and so far so good! Best part is we can do backups first just in case. I love this unit SOOO much better than my old locked down AN-21u!
[Android Head-Units] jpapadami:
Did you update over the 1gb or 3gb partion of Tuatara's rom?
[Android Head-Units] Black6spdZ:
I'm pretty sure 1.1.4.2 and 1.1.4.3 have 3GB partitions
[Android Head-Units] nestortoledo:
Thanks for the feedback.

I will update mine tonight. also have 1.1.4.3
[Android Head-Units] jpapadami:
Tuatara made a 1GB partition as per a request for version 1.1.4.3. That's why I'm asking.
[Android Head-Units] jpapadami:
Just updated as well, no problems. The only thing I have lost is the ability to dim my hardware buttons. Anyone else experience the same thing?
[Android Head-Units] pppeterrr:
How do you change the ringer volume for the

Bluetooth of the mcu

That volume is so loud, that for now i give it an ouput

Gain of 4db in Viper, so i can turn down

the master Volume.

But still it is much to loud

Maybe is it possible to change the audio file?
[Android Head-Units] amigo74:
does mcu40 support the standby time function correctly with firmware 1.1.5 ???
[Android Head-Units] Zaphod-Beeblebrox:
I'm hoping to have some time this weekend and I'll update the rest of the Bonovo apps with any code I've merged. Should get us to a 'pure' 1.1.6 with my additions.

I'm not fond of the CarpadCE name though. I'm assuming you don't like Android XDAuto (it's a mouthful, isn't it?).

How about we just call it xdAuto?
[Android Head-Units] Bokomaru:
I expressed concerns in an earlier post about the name. "Android XDAuto" sounds good, but doesn't fit within google's naming conventions. It could be "XDAuto powered by Android(tm)" or something like that.

I also wouldn't want this tied to XDA. As awesome as it is that it started here, if it ends up growing like I would expect and XDA doesn't create a subforum it will be unmanageable to deal with it here.
[Android Head-Units] ElfinJNoty:
What is the holdup with a subforum ?
[Android Head-Units] Zaphod-Beeblebrox:
You can go ask the XDA moderators, but I seriously doubt they'll create a subforum for this device. Very niche, small user base.
[Android Head-Units] Bokomaru:
About 4470 posts in about 8 months doesn't really deserve its own subforum. Now if there were enough users that generated that many posts in a month I suspect they would consider it.
[Android Head-Units] Firewater Burns:
Thanks, GoneMad seems to be working so far. I let an hour pass between starts and it didn't need to rescan. It skips to the next track on the list, but near instant music is great! It looks to be the second best option, after the ability to keep the USB active.

It would be nice if these topics could be spread out into different threads instead of buried in one huge one.
[Android Head-Units] zanix:
Added to wiki http://xdaforums.com/wiki/Newsmy_CarPad_NU3001/Custom_ROMs#CarpadCE_ROM

I like the name Android XDAuto, but I agree that it could potentially irk Google. Having ties to XDA isn't so bad either, but it would be nice to have a name that stands on it's own. CarpadCE kinda sounds too close to Windows CE to me, and the lack of that awful OS is what makes this device so great.
[Android Head-Units] Bokomaru:
Lol, I never even though about Windows CE. Why would anyone think about Windows CE or anything Microsoft for that matter? :)
[Android Head-Units] zanix:
Because every time I hear CE, that is what I think and I have no idea why. Sorry I brought it up... :confused:

It might be because a couple of years ago most of these "smart" stereos used Windows CE as the OS and just recently they used WinCE with Android running as a VM.
[Android Head-Units] nFKT:
As someone getting into this game late, is there a reason to buy the pure android newsmy carpad over the wince/android dual booting one? I assume the dualbooting one will boot wince first and nearly instantly at which point you have the option to boot Android.

Also is there any reason to consider the HuiFei units being that the hardware seems better on the newsmy side? Only issue I can find on the Newsmy is microphone related issues

Also if the Android is virtualized, perhaps the wince OS could be left on drawing much less power when the car is off?
[Android Head-Units] blacklistedcard:
I think the hardware is better made. No dead touchscreen, MCU, radio or android box. The software for other units is better, but there is full source code available in git hub.

I'm so glad I bought this unit instead of another brand.....
