I searched on ebay for "inductor 220 smt" and some similar items came up. Id probably read the wiki page on inductors to see how they are measured to get the right value though. "Smt" will get you surface mount vs through hole parts.

Cant say i have replaced an inductor before, they just dont seem to break on thier own...

Looks to me like you ordered a microphone (red board) and buck step down power converter (blue). Do you have links to the listings for these products?

I dont see an amplifier.

I would hook the power converter to vcc and ground. Then i would hook the mic + to out and the mic - to ground. So yes, two wires hooked to ground.

Thats what Id do, and it seems to make sense, but Id double check with an EE.
[MTCB Android Head Units Q&A] kxdelta:
You would Use Vcc and Gnd to power the module (+5V from your DCDC and 0V from the car/DCDC) and Out and Gnd for Your Mic+ and Mic-.

GND/0V is common, every piece of metal in your car is at this potential.

Hey guys, I've been doing a ton of searching everywhere and I haven't found any pictures of this model referenced anywhere. Wondering if this is a HuiFei or if anyone knows what it is. CPU is RK3066 according to the listing and specs seem to be the same, 1 gb samsung memory, 8 gb storage. It has a larger screen though and no DVD drive.

Anyone have any experiences with this one? Good or bad? If it is a HuiFei is it compatible with the firmwares/mcu on this page?

You may be able to harvest one from some broken electronics if you have a broken router, laptop, whatever. I'm pretty sure this is a common part. At the very least it would be good to get a practice round in before you rip the traces off your radio...
[MTCB Android Head Units Q&A] UlrtraTM:
From the Radio App and all it looks like its also an Huifei one. But im not sure
[MTCB Android Head Units Q&A] kaween:
You're not missing a thing, your question is perfectly valid and logical.

I'll help you finding out the answer to your valid question by yourself.

Know that in many languages "GND" or "-" in this case is also known as "Common Ground". :)

That should be a very big hint. :)

In the totally off-chance that wans't clear enough, yes, the "-" of the Mic and the GND of your car's radio and that amp board are one and the same.

Basically, the GND of your powerboard and the "-" of your mic should be -electrically speaking- one and the same contact point.

So if you connect the GND of the voltage regulator to the same GND of your car's headunit, everything's fine. (providing all your GND's are as they should be, in other words, "common")

This is very easy to check : take a multimeter, set it to Ohms, and if everything is done right, measuring between the "GND" of the amp and "GND" line of the headunit should show 0 ohm (or not much more than 2 or 3 ohm ... that zero ohm is in perfect and ideal circumstances).

Still waiting for my amp boards by the way.

---------- Post added at 04:15 PM ---------- Previous post was at 04:04 PM ----------

Oh yes it is. Meaning, I don't think it's a "real" Huifei, but it definitly belongs to the same family of devices we're discussing on this forum.

And if that unit whould have been available a couple of weeks ago, it would have saved me a lot of work : 7 inch with a 176mm facia opening was something I had been searching for weeks, but could not find.

Ah well. :)

On the other hand, I've never been a big fan of touch-button systems on car radios, and I very much prefer the physical feedback of a real button/dial. In case you've got a working SWC control, that doesn't make much of a difference of course. A plus-side of this unit is I think the screen itself is set much less "deep into the system" compared to units with physical buttons.

The screenshots say it's a KGL. It's a very clean interface, but personally, I like tactile buttons and knobs in a car. It's easier to use without looking at it.
[MTCB Android Head Units Q&A] Ploxorz:
Interesting, I thought it was but I didn't see any reference on this thread to 7 inch models. I had the same thoughts about physical buttons and was doing more searching, I found this model: http://www.ebay.com/itm/131522990652

This one is actually my ideal layout, physical buttons, and 1024 screen. Only thing I want that it doesn't have that would make it perfect is the quad core but all of those together is gonna be hard or impossible to find, would rather have the high resolution screen. I really like the look of this one and I'm probably going to get this instead, I really want a volume knob.

It actually has a picture of the settings page, the mcu is a jy and model says s07. Looks like it is the same except with physical buttons

It's not HuiFei -> Joying

[MTCB Android Head Units Q&A] Ploxorz:
Yeah I saw that seller on eBay, but they were selling the same units for way higher $. Is Joying what the JY mcu stands for or are they just a reseller? It doesn't specify the manufacturer on the front page just JY=JY. Ah well I don't care what it is as long as its compatible with these firmwares and I can root and twrp and update like all these other models.
[MTCB Android Head Units Q&A] kaween:
That's the one I bought as a RK3188 Quad core version. JY model. Real buttons. Was a bit of a pain to install it due to my dashboard size limitations, but I'm glad it worked out.

Both Malaysk's and DSA's roms work on this, there's a good 2.59 MCU with better sound available.

I've got a working SWC, but still I prefer the tactile feedback of real buttons. Only gripe I could imagine is the fact the screen is pretty "deep inside the bezel", which could make it slightly difficult to use in terms of touchscreen if you're blessed/cursed with sausage-sized fingers. :)

Other than that, it's very nice unit. I bought an 18€ USB DVB-T module and use it on this unit to have very cheap and good quality DVB-T reception : it permits touch-screen operation and hence looks and feels totally original : it also doesn't occupy a AV-input port, so i was able to connect both my front and back parking camera's and still have a real DVB-T solution which is brand/model independant.

[MTCB Android Head Units Q&A] kaween:
Sure.

http://www.aliexpress.com/snapshot/6653278660.html?orderId=67160887931597

Was 18USD, so it was even cheaper than I remembered. There's also a slightly more expensive verseion with DVB-T2 (Gica P360, http://www.mygica.com/html/TV_Tuner/20140802/60.html) which works very well too, has a more sensitive tuner/better reception and is rumoured to get DAB+ capabilities later this year.

Remember to buy a DVB-T amplified antenna for these units, otherwise the reception is cr*p : the antenna that comes with them is totally useless. :)

[MENTION=1347258]ESTIMULO[/MENTION] : euh ? No it works independant if you drive or not. There's absolutly no limitation or control in that aspect, unless you mean "hey it's no diversity receiver and it will drop signal when driving and you're not in the vicinity of a DVB-T transmitter station" - in which case you are correct.

But I only use it when standing still, it's super when I'm sitting in my car waiting for the kids or whatever and I live nearly "under the antenna" here.

I think all these units use the same software (PadTV), can't really complain about them : it works better than the model specific build-in DVB-T tuner of my AN21 does. (better reception, much clearer picture, clean interface, EPG and recording capabilities). Don't have any real issues with it, other than I sometimes have to manually kill the process after watching to "release it" when switching from and to the radio application.

Still have to force an automatic kill with Llama or something, pretty sure it will work out just fine after that. But other than that : no complaints.

Warning : could not get PadTV nor PadTVHD to work with Malaysk's roms, DSA was no problem.

Everything works just like I want now, but I got a lock screen issue, half year ago when I was trying to change some stuff within connections and suddenly the lock screen was activated, it doesn’t come up all the time but after every boot when I try to open a app I get a lock screen, luckily the pin code I used was easy but I don’t want this.

After a lot tries and search I can’t disable this, there is no VPN configured and I tried the 5 times wrong pin code trick but it just says “Try again after 30 seconds” but it won’t ask me the Google account information. I even installed the Lockscreen Disabler but it didn’t disable it.

How to attach external bluetooth mic to eonon GA5151?

As a newbie this is a great resource and thanks to those involved. I recently purchased Eonon GA5151 and as thread 2660662 describes the bluetooth microphone is awful on phone calls. So I opened up the unit to see if I could connect a new external mic socket to the bluetooth board but only got as far as folding out the front fascia and removing the front panel microphone pcb - photo link here and didn't see how it connected to the BT module. Do i need to get to the main board under the DVD player ? Any advice on what to do next would be appreciated.

Amp turn on does not work now

I upgraded to the latest MCU (GS2.55) and latest software for Malaysk last night and now my subwoofer amp does not turn on. There is no power to the blue turn on wire at the amp.

[MTCB Android Head Units Q&A] Ploxorz:
After doing a bunch of searching and a comment from someone here this seems to be a joyous unit(could be wrong), which very likely has a jy mcu that is updated on this thread.

Looking at the pictures it looks like it does support video output to two screens, but only component. Should support playing videos from sdcard and usb I would guess.

Not 100% sure on this, but I think that's right.

What do you mean "dashboard size limitations"? I have a Joying RK3188 7 inch too and went through hell finding a dash kit that I could easily modify, modified it (turned out ugly) and now I'm worried it won't physically fit in my dash when I try to install it tomorrow

[MTCB Android Head Units Q&A] mike.s:
Don't they all? I assume you're thinking you can play a media file on the rear while seeing nav on the front. I highly doubt that - it would require that Android support multiple frame buffers (not double buffering, which is different). AFAIK, that's not supported. When I searched, references to dual or multiple screens were actually about supporting screens with different characteristics (e.g. size or resolution), not supporting a screen-per-app type thing.

The units which don't have DVDs run the same firmware as those which do, so it's not clear where you got the idea that they could do more with less.
[MTCB Android Head Units Q&A] ojuniour:
I don't want PIP (picture-in-picture) like those window CE-Android combo...

I just want to be able to play video from my sd card to the headrest instead of the dvd.. I don't mind if it's just mirroring the whole android OS.

The point is....nowadays who uses dvd anyway.. when you can just store files into sd card.. or even stream from youtube.

The current KGL unit i have can only play from the DVD to the external headrest.. And that's about the only video feed outputted from the unit.

I've been looking at a ton of these and I'm left wondering if there is one model that outshines the rest. Quad core, high res, best GPS, best build, most reliable, least buggy?

[MTCB Android Head Units Q&A] kaween:
Originally, the car had only a 1din mount and dashboard clearance. I had reworked the complete stuff to 2 din and specifically for the "Narrow/Honda" like dashboard opening my new radio used.

It was an easy fit. But I soon found out the decission to go for a 172x97 mount was .... well it was just plain stupid on my side. :(

The main problem for me was that I had no space left "at the bottom" : compared to the JY, the previous unit was about 4 mm less high and 6 mm less wide, and that was a 100% tight fit so I had no room to spare.

On top of that, I could not simply make the opening in the dash bigger at the bottom side, as there's a fixed safety buckle indicicator which I can't move. So I had to "shove the complet stuff up" for a couple of millimeters : had to remove the radio cage, alter the underlying dashboard parts and cage mount to move the radio up a bit, rework the bracket system as the old one only accepted a 172mm wide unit ect ect ect.

Turnned out great, but it was fiddly work (testfit, modify, testfit again, modify some more .....).

The fact the dash itself is laquered/painted with some wood-like colour and I had decided to try to avoid repainting the dash by working VERY carefull around the painted parts, because one slip-up meant "repaint".

Took me a complete day to make it all fit while keeping a factory look.
