Yes I know, I ve already seen and commented on that picture, but it doesnt change the fact that the Chinese are on holiday until March, I ve checked the Klyde sources I know about and the latest available is V2.21, so you will just have to wait until March, unless you want me to fly out to China and break into Klyde's offices ?? !!

Hi.

I have funny problem with my FM adapter.

So, this is normal fm adapter, added to my radio:

It works fine, but the signal strengh is veeeeery low. Only noise and only few FM stations

Seller send me this FM adapter and told me that i should connect it with blue ANT wire like as on the picture below:

With it i can't reach any FM station, also there is a green led but it is always disabled so as i asume, this FM amp doesnt work.

this is how it look inside:

any ideas how to fix it and make FM signal much stronger

I almost gave up... tried everything to make a 3G dongle with the 4.4.4 Klyde Android. My unit (Klyde for the Nissan Sentra/Selphy) came with 4.2.2 and a Huawei E173. It works fine with 4.2.2. Then I upgraded to 4.4.2. Sometimes I have to connect and disconnect it to work. Then I went to a rooted 4.4.4 and also Coudu builds. With those the signal bars sometimes appear, but empty.

I tried also several other modems: Huawei E1553, a 4G ZTE, a 4G Huawei... nothing. The 4G ones didn't work even with 4.2.2. I already changed, via terminal, the status of the modems (modem only, disable the autorun and memory card slot).

I build a bypass cable in order to power the modem from an outside source, in my case a 12v to 5v converter (cigarette lighter - 2.1 A), but it didn't help at all.

Any clue???

[MTCB Android Head Units Q&A] TooBusy:
It's been confirmed many times that 4G USB dongles are not supported on these units. Don't bother trying. If you need 4G, use a WiFi modem.

My dongle didn't work in modem-only mode. Only after resetting it to defaults, it's started working. Have you tried the dongle in default mode?

You might want to try [MENTION=6041319]dsa8310[/MENTION]'s script with logging enabled, check the log, and see if you get any idea from logged messages.

I've got my dongle eventually working, but that's not the end of the story. The connection drops often and it takes time to come back. When I have WiFi connection, data connection is lost. Nothing new really; all these things have been reported earlier. It would be good to get a feedback from someone who has a USB 3G dongle working reliably for some time (2 - 3 weeks). Without feedback like that, and if the issues continue, I'll come to the conclusion that 3G is not reliable, not worth the trouble, and go for a WiFi modem. But Internet connection is not essential to me, so I am not too concerned.

Hey guys, sorry if this has been answered, couldn't find any info...

I work with HuiFei units on a daily basis, and they're fine, but one thing I can't help but wonder about...

why don't the units (I believe pretty much all Android navis?) support factory amplifiers/sound systems, like Bose, Harman-Kardon, BMW DSP's and such? Is there a special controller involved in the amp and factory radio/navi, or some sort of protection? Or maybe the CAN bus decoder is the case? I think I've seen some units online working on WindowsCE or something else that

did

support factory systems...

For example, in some BMW's we have to install a 6 meter cable that runs from the dashboard to the back and plugs in directly into the radio tuner and speakers... completely bypassing the amplifier, which some clients can't stand.

How to make this work?
[MTCB Android Head Units Q&A] pk313:
on my kLD 4.2.2. i decide to make some ...experiment with the iPod input, on KIA and Hyundai there is an aux OEM input for iPod/Aux(audio jack)/Usb,

with the OEM Radio was working nice as input for ipod (with OEM cable adapter) and USB.

I decided to modify Ipod connection of KLD and try to interface with the multimedia OEM adapter....but is'n working properly as....expected,

So i want to identify if with some small modification can be work properly, so what's appen now is this:

If i connect Ipod only with an usb cable, Ipod go in charge, KLD switch automatically to Ipod input, read music inside, i can take command of ipod, but i have no audio and is normal, not connected (is not connected by the OEM cable, that include audio jack).

If i try to use OEM cable , with usb and audio jack, seems is working ...contrarywise, i mean as soon i connect plug, KLD detect that Ipod is disconnecting from radio and not connecting, some switch to the audio jack of OEM interface (because if i connect only by and usb cable to Ipod is detecting connected)

Probably noting to do....but if somebody on the past have play with Ipod inputs and adapters may help me

Attached just to understand the OEM Multimedia connection if somebody is ..familiar with this kind of adapters...........

if i discover how to interface KLD with this part of the car will be ....complitely integrated!!

Sygic Fix?

[MENTION=4344041]komir[/MENTION] I may have a solution to your Sygic problem as I fixed mine last night!

I was attempting to get a USB 3G dongle to work (without success). Afterwards, I thought I'd take a chance and try Sygic and it worked!

When parked outside my home, my car is connected to my Wi-Fi router located indoors. If I need internet access while on the road, I can use my phone as a mobile Wi-Fi hotspot. My HU is never connected to the internet through the 3G dongle as it doesn't work (I believe the dongle does work but the network provider have blocked the SIM card as it's not being used in a phone - http://xdaforums.com/general/general/true-payg-data-sim-t3033363). Anyway, maybe Sygic have been changing things behind the scenes and fixed this fault? Or maybe the Sygic software needed some sort of location signal which was provided by the 3G dongle and that sorted it?

So, Sygic didn't work when connected to my home Wi-Fi router or phone's mobile Wi-Fi hotspot, but it did last night when connected to my home Wi-Fi router and with the 3G dongle connected.

Give it a go. I don't know if you're using a 3G dongle or not, but you could now try it without a 3G dongle just to see if Sygic fixed the problem behind the scenes and the 3G dongle just coincidental.

Let me know.
[MTCB Android Head Units Q&A] pakidermo5000:
I am also struggling with the sound and made quite some research. The problem is not the HU, AFAIK they support amp and everthing, the problem is the systems that are half amplified. The fully amplified systems should have no problems. Also the harness can be a problem if you do not purchase the proper one.

In my personal case (Audi A3) the factory system is half amplified on the rears. In practice it means that in the factory setting, a low level signal is sent to the amp, which then sends the signal to the sub and the rears. The front speakers instead are connected straight away via CANBUS. The actual problem with the HU is that it outputs much more power than the factory HU. Then, you end up with this:

Factory settings: 2W Front + 1W Rear/sub --> after the rear amp = 2W Front + 2W Rear/Sub

HuiFei: 4W Front + 4W Rear/sub --> probably after the rear amp = 4W Front + 2W Rear/Sub

This makes that the sound of the rears is very low compared to front. You can play with Fade, but it is just not the same...

So,the solution for this half amplified systems is, either reduce the output of the fronts (which will probably lower the sound quality) or upgrade the sub and rears, which implies adding an extra amp for the sub and/or rears.

The other option as you do is tap the rears directly to the HU, but yes, that involves passing 6M of cable to the back of the car and bypassig the amp. Adding the aftermarket amp also implies 6M of cable... but it will give better sound.
[MTCB Android Head Units Q&A] NaviPR:
So I double-checked in terms of compatibility and I was informed that the unit should work with most brands without a problem... but it's interesting that dsa8310 had to use that Toyota cable.

There is definitely a problem with BMW's and Mercedes-Benz cars with factory sound systems, where the amplifier has to be bypassed and the HU has to be hooked up directly to the speakers. I was told it has something to do with the CAN bus decoder, is that true? What could be the reason for this? It would be awesome to make the HU fully compatible with every option out there to avoid problems...
[MTCB Android Head Units Q&A] pakidermo5000:

[MTCB Android Head Units Q&A] TooBusy:
I didn't look at the front page for a while, but I just had a quick look and noticed that it has a link to this post (#8383). It would be good to include a little bit more information.

The above applies to no-name cams purchased with the HU. They are not high quality and can record only at 640x480 even with DailyRoads Voyager. CarRecorder can only use 640x480 with any camera. However, better quality cameras can record with higher resolutions when used with DailyRoads Voyager or another app. I tested Logitech C930e: very good on 720p, and it can even record with 1080p, but with about half the frame rate of 720p, so 720p seems to be the best option.

------------------------------------------------------------

Also the front page "3G USB Dongle not working properly" has a link to post #7614. I don't see why.

---------- Post added at 12:24 AM ---------- Previous post was at 12:04 AM ----------

I see this solution similar to two batteries connected in parallel. The current will go from one to another, unless they are exactly the same. In which direction? When no USB device is connected, and the original source is protected with a Schottky diode, and the DC-DC regulator probably has something similar, there should be no current in either direction. Why not check it? It's more complex when a USB device is connected. From which source will it draw the power? This depends on the internal impedance of both sources, as well as the impedance of the USB device.

Regardless, it looks like it's working for those who made the modification, so it's probably OK. I'd rather use the DC-DC regulator to power a powered USB hub.

Hi Folks, hope you can help me.

I have an Eonon GA5153 (Klyde) and I like coudu's rom, I've tried different version (4.2, 4.1, 3.x), but Radio doesn't work.

So I've installed Malaysk's Rom and everything works fine, but I just don't like the way it looks.

Is it possible to get malaysk's rom look similiar to coudu's rom?

Yes, I didn't try with other camera than the one which came with HU, but if you say its working to record in 720p, then it's excelent.

Review about the modified ppp script from DSA8310 :

I used my unit now for 3 month ago. I drive about 1000km a week. Normally there are problems with the 3G connection on long drives. Also with the "mobile connection settings" app.

Now with the script from DSA8310:

So on the last 1000km the signal comes everytime back after the signal was getting lost.

So I tried it on a different track on Monday, but at the moment I would say : it works. So if you got some problems with your 3G Dongle try the script. I use it in combination with the mobile connection settings app.

First of all, I don't have a BMW, sorry (for myself, not for you).

Did you check that there is 12V on pin 16? It might be the opposite - pin 16 expects +12V when the radio is on, in which case you may not even need the additional FM adapter; just connect the blue AMP wire from HU (if you have it, or connect to red ACC, as suggested by [MENTION=726096]antfros[/MENTION], if you don't have it) to pin 16. Don't try this before you know what pin 16 is really for (where it's connected to), or you could damage something. If you can't figure out what pin 16 is for, hopefully someone with the same car will help you.

If all else fails, how about we swap cars?
[MTCB Android Head Units Q&A] juliocohen:
Thank you, Toobusy for your message. And sorry for returning to the subject, unfortunately we have only one thread to discuss everything HuiFei and it's really hard to find everything that was written in almost a thousand pages!

When I bought my Klyde unit, I noticed that in the back there is one multipin connector for the two USB cable and another one labeled "rear USB". Well, I wrote to the seller and he sent me a single USB cable with the proprietary connector for that port (purple color), as you can see in the photos above.

Well, I live in an apartment and it's hard to test, go back everytime to the car with a new SD card to the garage - three stories above me. So I decided to disconnect the unit and power it in my workbench and play with the new cable, modems and Android ROMS.

So I plugged the modem (Huawei E173) in the "rear USB" port, unused up to that point. The unit was with a rooted 4.4.4 and, surprise, full bars and 3G icon appeared. Then I flashed with the KGL 4.4.4 from Coudu. I really like the Appleesque icons that matches my iPhone. For my surprise, again, modem working fine. Power on, off, on, several times, 3G connection always good. So I setup it with my settings and all the apps I use and installed in my car.

I drove about 50 km with a perfect connection, always listening to SiriusXM Internet Radio and Waze navigation.

I kept the other two USB cables (labeled 3G/Wi-Fi) disconnected. I think about the lenght of the new cable, very short, but later I connected it to the USB port in the central console with an adapter and the 3G modem still runs ok.

Just to remember, I never got a 3G connection with any 4.4.4 Coudu builds using the other USB ports (the split cable I had). Now I have!

Until now, very happy with the results. I really need the 3G connection while driving and tethering the connection for my daughter works too.

(I was using the F connection, now I am using the B. The unit doesn't have the front USB connector)

[MTCB Android Head Units Q&A] TooBusy:
This is the dilemma that I faced a few days ago when installing a battery pack for my dash cam (parking mode). There is no switched 12V coming from the car wiring harness. The only red ACC wire on the HU is thin; it's switched on by CAN bus decoder; it's good for LEDs and similar, but what's the max current that you can use safely? Maybe a few mA, not 1A. I connected the battery pack to the fuse box. If in the future I decide to provide more power to the USB ports, I will probably also use the fuse box.

[MTCB Android Head Units Q&A] pakidermo5000:
I am pretty sure most of these problems are current related. I see many people having problems with a specific USB port (usually the rear ones). I had the same with my rear ports. Having a powered USB (hub) will certainly help. Think it through, a 3G dongle is just a gadget that uses electricity to generate an internet connection. If it works with any computer, it must work with the unit. The only problem is that the unit USB can be underpowered, and can make the dongle work erraticaly.

Before doing any major mod use the lighter to power your USB hub and see if it works. If it does, then you know what to do.

[MENTION=6041319]dsa8310[/MENTION]

regarding the permanently hot USB, you were right. It always has current, although the pendrive stops (I guess when unmounting). The ideal case for that is to add a relay. This is, take the yellow 12V cable (permanent) to a relay (normally closed) and use the red cable (ACCin) as switch for the relay. T
