Hi all. I can't find the answer in the FAQ: how do I update the MCU? Can I do it from within the system itself or do I need an external computer attached? I have the files downloaded but twrp won't install rar. What now?
[Android Head-Units] pawcu:
Check the wiki from the following link:

http://xdaforums.com/wiki/Newsmy_CarPad#Update_MCU

Basically just extract the files on the root folder of the sd card > boot up your radio > go to the MCU application (I believe its called 'Update Settings'? im not sure though) and click check for update and it should find the update file. Make sure wifi is turned off as sometimes this causes issues. Gdluck :)
[Android Head-Units] octavecat:
Perfect! Thanks so much. Worked.
[Android Head-Units] sinnedone:
Ah ok. I was thinking sd card write speeds had something to do with it.

Have you tried a lower resolution or bit rate?

I want to try to make my own mic to fit in the OEM location of my car. Anyone know details on the mic in the NR series? Why is there an internal mic that is against the screen? And why two mic elements in the external mic? The Bluetooth board appears to have a couple of op amps on it. I am wondering if Newsmy is trying to accomplish some sort of noise cancelling?

Hi all! I just purchased the NR3001 and have been playing around with it. I haven't installed any custom roms yet. I have an issue, i searched the forums but i couldn't find anything on it. When using Google Maps or HERE maps the GPS would lock instantly but it doesn't seem to know the direction i'm facing. I'll be heading West or South and the location icon will move correctly along the map, but the arrow that shows which direction i'm facing will always face North. Anyone else have this issue and know a fix for it?? Thanks!
[Android Head-Units] pawcu:
It should follow the road of the map. Atleast with sygic and Google maps that's how it should work. The unit does not have a magnetometer so the arrow should start pointing in the direction of your velocity once you exceed some 5kmph if I'm not mistaken.

I did try lower resolution. I need to try lower framerate and bitrate. I will also try an old webcam I have that I know works atleast on my pc. I'll guess I'll fiddle around with the settings hopefully I find a sweet spot... The problem is that testing is hard as the video flickers randomly ?

Received an NR3001 today, got the wiring harness hooked up, and verified several times it was correct. Several issues right off the start:

- no sound, from any source. tried FM, youtube via browser (wifi via hotspot), and bluetooth from my phone.

- Kingston DataTraveler thumb drive isn't recognized by ES File Explorer. Went into Settings / Storage and it was listed there as USB Storage with the correct size, but I can't access it anywhere.

I figured I'd try updating [stock] everything I could, but I can't even get access to the contents of the usb drive. Did I receive a bad unit, or am I missing something obvious?

Stumbled across a post that mentioned FAT32 formatting for thumb drives and a lightbulb went off. Formatted a new drive FAT32 and was able to update the stock ROM. MCU was already up to date on the latest.

But yet, still no sound from any source. Suspecting now that I have a bad unit. Anyone else run into the same or have any ideas on how to troubleshoot this?

Well it all came down to the fact that I own a 2006 (WK) Jeep Grand Cherokee, and the CAN BUS systems in the early 2000s were the first generation. The C2R-CHY4 module you have to use with aftermarket head units for my model had a blue/white wire, which I neglected to hook up. Rather, I connected the straight blue one, which made sense at the time. Once that wire was connected to the blue antenna out of the NR3001, the sound came to life. Always the little things. Hopefully someone else might see this and benefit from my dumbassery.

Hello,

Does anybody knows if it's possible to set the HDMI external screen resolution to 1024x600, that is the same resolution of the head unit screen? May be modifying the firmware? Actually the resolutions available are: 1920x1080, 1280x720... but not available 1024x600.

Also, the output sent to the external screen is mirroring the main screen. Is it possible to send one application to the main screen and another application to the external HDMI output screeen?

I'm looking at https://github.com/Nu3001/kernel_rk3188/blob/master/drivers/video/hdmi/chips/anx7150/anx7150_hw.c but I have no clue of how to set a new resolution...

Bootloop

Hi, guys.

Just bought Carpad 3 NR5241HH0, specially for Kia k5 model,

after upgrading to 1.3.9 version i decide to install ViPER4Android.

with the help of the KingRoot, I got root.

And after installation Viper's drivers i got bootloop.

Crazy dancing with the reset button does not help me to enter in recovery mode. no old or new devices in device manager, RkBatchTool can not to detect any connected device.

I tried to hold reset and insert cable before after or in one time with button release. Used a combination with power button and so on.

But i'm failed

Maybe someone knows a exact steps or could give me a advice?

I have no anymore ideas what to do with bootloop/.

Thanks

twokidsandaphone,

Finally got my SWC working in my F-150. Ended up having to purchase an OTG cable to connect my phone to the Metra adapter. Metra tech also told me that I had it wired incorrectly. I had the brown wire going to Key Gnd and the brown/white to Key1. He told me to lose the ground wire and connect the brown wire to the Key2 wire coming from the HU. So both wires from the adapter 3.5mm plug are connected to the Key1 and Key2 wires from the HU. Sounded crazy to me but it worked.

Once I reset the adapter, I connected the OTG cable to the adapter and using the Axxess updater app I programed the adapter to one of the 16 radios that are in the adapter's database. The tech told me to start with the Pioneer/Jensen radio, which I did and that was it. I was able to program all of my SWC buttons as needed.

Many thanks to you, twokidsandaphone for helping to figure this out, and many, many thanks to all of those who have worked on the development of all of the software for this HU. You guys are awesome to put forth the personal effort to make these files, and then to make them available to all.

Many, many KUDOS to you guys!! :good:;):)
[Android Head-Units] robertusIT:
guys i have found another great features from another android radio

so you can connect your phone via usb and control your phone from radio, like pioneer appradio.

The cpu is the same like newsmy, RK3188, is possible get this feature in our NU3001 and NR3001?

Hi, just a quick one...

I'm thinking about buying 2DIN android unit with RK3188 and I need information does those units suport USB DAC ?

(thay state that it suport OTG)

[Android Head-Units] frankmehta:
Yes. It most definitely works. I have an elaborate audio setup in my car and I'm feeding 96/24 sound from my head unit via USB to a dac which outputs sound to my processor.
[Android Head-Units] twokidsandaphone:
Hey! That's great! Glad you got it to work, thanks for the kudos (even though most of what I told you turned out to be wrong :eek:). You should consider taking what you wrote above and making a small tutorial and placing it on the wiki page. I think a lot of people would benefit from it, as the ASWC is very popular and the hook-up is obviously not straight forward. I will soon be attempting to use a Connects2 with an NR3001 if my plan to buy one for my car comes to fruition (the one we have is in my wife's car)

Does FM radio and BT (mobile phone connection for calls) works via USB DAC ?

(have read somplace that it doesn't work...that's the reason why I ask ;))

(I'm thinking about buying joying based on RK3188 1.6GHz Cortex A9 Quad Core with 7' Resolution 1024*600)

v1.4.0 update is out... however can not download it from baidu? anyone was able to download it?
[Android Head-Units] zanix:
No, only Android will output via USB.
[Android Head-Units] nu!me!:
Agggrrrgghhhhh...

I was hopeing that fm amd BT would work...

O.K I can live without FM (can use tune in or something like that)

But how to solve phone call's ?

As I need, or like to have hand's free phone call's whole driving...
[Android Head-Units] zanix:
The audio quality straight from the unit is pretty good, also you can use the RCA outputs to an amp.

I have the NU3001 with only front L/R RCA outputs so I use RCA Y splitters on each side to connect to 2 amps.
[Android Head-Units] nu!me!:
I will have this unit connected to JBL MS8 and then active 3way + subwoofer...

I'm more for SQ but will have to see what I can do about sound once I recive/install HU...
[Android Head-Units] zanix:
The only issue I have is a very tiny bit of engine noise in the speakers, but that will go away once I get around to installing a ground loop isolator. It hasn't been very noticeable otherwise I would have put it in by now.
[Android Head-Units] nu!me!:
Tnx...

Somehow I think that all those chines units are generic just other brand name...so I belive that joying is more/less the sime as yours unit...and can expact the sime ground problems...o think that with usb dac I will not have that problem...but will see... ;)
[Android Head-Units] zanix:
It is possible to have the same problem with USB DACs, ground loops can affect any part of the audio chain.
[Android Head-Units] twokidsandaphone:
Pulled the trigger on another NR3001 (this time for my car). I was strongly considering getting a Joying for my wife's car instead and putting the Newsmy in mine, but didn't do it. I paid $400 US shipped to Canada through Summer using Paypal to pay newsmy-car directly, which includes the 5.1 cable.
[Android Head-Units] Dream Reality Syndrome:
Where would you install the loop isolator?
[Android Head-Units] zanix:
They connect inline with the RCA outputs
[Android Head-Units] Dream Reality Syndrome:
Digging your setup! I currently have the NU5002 rca out to 80PRS to an Eclipse EA4100 and Cadence iA7. ID CD Pros w/mini horns, Cadence CVL64MBX and Sundown SA12's.

Does the miniDSP make a decent difference in sq? And what Android OS are you running your HU?

I'm waiting to install an Audison Bit One, Victory Sonics tube pre, Leviathan v1, Hertz HDP1 and order ID Max 12s. Wondering about that dac!
[Android Head-Units] frankmehta:
Fm, BT work via RCA. My processor has 4 inputs which are configurable via remote. I have set digital on no. 2 and analog on no. 1 and routed my inputs accordingly on the processor using my PC.

The moment I want to switch over from Radio to Digital Audio I just need to press no. 2 on my auxiliary remote.

And my rear speakers are connected to the in built amplifier of the head unit. So if I get a phone call while listening to digital audio, I don't need to switch to the other mode, my rear speakers help me complete the phone call.

All this may change when Lollipop comes. After LL, you can have complete audio output over USB.

If you're happy with the sound over RCA, you REALLY need to hear 24/96 Digital Audio!

This is a good way to do it, but try using USB out and connect to a USB to SPDIF converter and output to a Processor. This way, you can remove all equalisation from the unit. The sound via RCA is via the MCU, and not the native DAC on the chip.

I am running Newsmy stock 1.39 rooted. The MiniDSP is my star. USB output to a USB to SPDIF converter and then that SPDIF directly into my miniDSP means there is NO dilution of signal. Try it. Just do it once, and you will never go back!
[Android Head-Units] zanix:
Correct, while FM BT and Phone output over RCA, they will not work with a USB DAC.

This is a good solution to get FM/BT/Phone while using a DAC.

Unfortunately with this unit (and many other Android Head Units), the audio from FM/BT/Phone never go to Android. All audio is all switched at the MCU so you will never get audio from FM/BT/Phone over USB.

I think 24/96 Digital Audio is overkill in a car where the road noise and the sound of the engine would take away from the sound. Plus my primary sound source is MP3 via Google Music so I'm getting at most 320kbps MP3.

Good point, but I don't think the MCU processes sound at all. It seems like the MCU just acts as a switch for the various audio sources. I think the DAC from the Android portion is mostly unchanged until it's amplified for the speaker output.

I feel that after road noise and the engine, you are not getting the full benefit of the DAC. If this was in my house I would fully agree, but in a car I think it's overkill.

I'm not trying to say that your set-up is wrong or bad, I just wanted to get my view accross. If you like it then who am I to say you are wrong?
[Android Head-Units] frankmehta:
It so happens that a 24/96 is not the only track that plays via the dsp. Even regular 320 kbps sounds way better through USB out than rca. Also, my processor does the crossover and time delay for the speakers which is paramount.
[Android Head-Units] RC54:
Hey thanks Jeff, I'll consider that. I've never written a tutorial before but I think I might give it a try, now that I have all of the details.

I am really enjoying my SWC! :D;)
[Android Head-Units] AlTB:
And both of the units you were posting offer RDS :good:

Just Newsmy is not able to implement, so the radio is sensless in Europe :laugh:

Can you post a photo? I have mine installed in a Citroen C1 2010, no problems here.
[Android Head-Units] nu!me!:
I did some reading...

as I understand

MCU is chip (let's say BD37534FV) which acts as switch betwin ''android'' , BT, FMradio output

What if we would phisicly cut traces on that chip...

Let's say that HU android output comes to the pins 1 an 2 (L and R channel),

and if we use USB DAC for android,

we could cut tracis 1 and 2 from unit ''HU android'' and solder at those places output from USB DAC ?

that way, we can have ''beter qualiti sound'' on the input of MCU from android part of HU ?

and we will not lose the FM or BT ?

p,s, sorry for bad english...can't use spell check

ps, JBL MS8 have only analog inputs, and it have 2 inputs, but it's not that easy to change from one input to the other while driving...so I would much more like that it's done by HU
[Android Head-Units] zanix:
This is the audio processor for the Android portion: Wolfson WM8988L

From the wiki http://xdaforums.com/wiki/Newsmy_CarPad#NU_Hardware

As for replacing the input from Android and adapting a USB dac to go in-between... I guess you could do that, but I have no idea where the traces for the audio lines are. Plus in the NU models you would need a USB cable to go back to the Head Unit and probably mount the DAC inside it. I think that would be way too much for work for what (in my option) would be little benefit.

I have used a DAC with this stereo before, this one to be precise, and I didn't think it provided any better audio output than the regular output.
[Android Head-Units] nu!me!:
whell, wolfson does know how to make good DAC, but implementation is the key...

hmmm...will see how it will look inside JY HU...

all those cips are so small, and I don't know will I be abile to cut traces...

I was thinking to use ES9023 or the ES9018m...

http://hifimediy.com/Sabre-9018-DAC

http://hifimediy.com/9018-dac

but then again, my setup would take digital signal to analog, then MS8 will take analog and turn it to digital and again to analog...so...I don't know...

Isn't RDS available in the xdauto rom?

Also anyone find a good usb tv tuner that works?
[Android Head-Units] Zaphod-Beeblebrox:
RDS is not available in xdAuto. I tried to work with Newsmy to bring this about, but they refuse to share all of the necessary code, and had me chasing my tail on supposed API's that simply don't work. I have very limited time to devote to this project lately, and wasting that time on fruitless pursuits quite honestly pissed me off.

The only thing that this unit had over other units at the time I bought in, was the availability of source code. The hardware was a little above par, but other units have quickly caught up and their software development is worlds ahead of Newsmy. had I known that the source code we had was purely by accident (which is a bit of a testament as to just how inexperienced their software engineers are - they were using baidu accounts to transfer the entire source code back and forth!), and that we would not receive additional support, I would have went on to something else.

Fortunately, the radios work pretty well for my basic needs, so no real desire to rip them out. However, I can assure you that my next 'project' will not involve a Newsmy device. I'll probably go back to the DIY world and roll a tablet install.

Thank you for the response, and that's really sad to hear. The main reason I purchased one of these units was for the community support.

Especially since with these units I knew there would be some bugs/UI inconsistencies, but the community and those that know usually step in. :)
[Android Head-Units] shellscape:

The lack of GPS lock is related to the MainActivity process hanging. Every single time I'm monitoring the GPS lock, the second MainAcitivty force closes I get an instant lock. No ideas on how to solve that one...so I'm gonna try flashing xdAuto.

look at your car

a 10.1" tablet won't fit mine because the dashboard is in the way (2-din unit is somewhat recessed into the dashboard, will need a replacement dashboard)

I installed NR3001 in a 2006 Honda CR-V (or 2002-2006 Honda CR-V series)

Notes (might be useful for someone else with the same 2006 Honda crv)

- Purchased separate wiring harness for car (Metra 70-1721)

- L bracket used to secure radio to car

--- the one provided won't fit

--- can reuse the L-bracket from existing stock car radio

- I routed all the wires (2 USB, GPS antenna, mic) down to the bottom of the center console, below the fan/temperature control (there's a small drawer there to store the cables)

no swc/rear camera, which makes things easier

A few issues with software

(Launcher/Maps stopped unexpectedly a few times...

Mic works in Audio Recorder app, but not in google maps/play store voice-search

Software update would probably fix this)
[Android Head-Units] twokidsandaphone:
Yes very unfortunate and frustrating I am sure. I just ordered a second one and part of my hesitation was the fact that I had gleaned from this and the xdauto thread that Newsmy was not being very fair to the developers and that development was waning. I certainly appreciate the work that has been done, I would definitely not be considering another if it was not for xdauto and its developers.

I almost went for a Joying unit, but getting mixed messages on bluetooth quality, build quality (as noted again a couple of posts back), and sound quality. Still, now that Zaphod has declared he is out, I am wondering if I should cancel (if I even can) and order a Joying after all.
