[MTCB Android Head Units Q&A] typos1:
In the UK DVB-T tv also has radio channels, here no one is "pushing" DVB-T for radio - actually we are "pushing DAB" - its just as digital tv also broadcasts radio, its a possible solution to not having DAB/DAB+ on these units. Does digital tv in Denmark not have radio channels as well ? I m confused when you say there is a "limited number of broadcasters", I thought all your tv was DVB-T ? Or is that radio is not transmitted ?

The earliest record of these units is from youtube in November last year, when the Klyde factory uploaded a video, so if anything Klyde is the original manufacturer, but NEITHER the RoadMaster, Klyde or HuiFei/KGL are clones, these manufacturers ALL buy the kit from Rockchip and make their products from that. There is no point in only focusing on the HuiFei units in the mistaken belief that they are the original or the best, nothing on this thread points to any of the manufacturer's versions being better or worse than any of the others, they are all much of a muchness, they are all effectively the same product, with very minor differences. So holding out for a "genuine" HuiFei unit makes no sense (there are no fake HuiFeis !), it would be much better to look for one with a front that you like at the best price, regardless of whether its an RM, HuiFei/KGL or a Klyde (or even a "GS" version). If we HAVE to try and decide which one is best, it would be the RoadMaster, versions because they use a Toshiba amp chip and Toshiba is a well known brand (claims of other units using either Toshiba or Phillips amp or radio chips are INCORRECT), but being a well known brand does not mean it will necessary be the best, as well known brands are not perfect and often make mistakes or bad products themselves (Toyota's well publicised recalls, Mercedes' falling over A classes, Samsung's overheating Exynos processors, to name just a few examples off the top of my head). I ve picked a Klyde version, but only because they are the only ones that make one for my car, I d happily have ANY of the others. NONE are clones, a clone is a copy and NONE of these are copies, they are ALL genuine Rockchip Android headunits.

The interface looks much much better with the pro version, would be better if there was a widget for it though, so you could run it on your homescreen like the built in FM app.

Is there no way to get channel name, info etc ?

With our I mean fellow Klyde owners I compared the specs from this thread:

With the specs from the supplier:

http://www.ebay.com/itm/Double-2-Di...T-Navigation-Bluetooth-IPOD-OBD-/171380870456 (bottom of the page)

Which all lead me to the impression that I own a Klyde unit, correct me if I`m wrong though :confused:

I thought this was just an MCU update? The wifi drivers are part of the kernel, which is usually part of the update image (system, kernel, boot, recovery, misc, oem).

Hi,

I didn't read all the posts after this one, it's very confusing in the middle of all the topics within this one... but... what did you do about this?

I think the same happened to me :( The speakers didn't blow, but one of them is too low and a lot of background noise now (specially after I turn on the ignition).

Steering Wheel Control help

Curious what adapter I would need for this head unit for my steering wheel control. I have a 2008 Nissan Altima and live in the US. I am sure it would help if I had a model number, I am waiting for the seller to send it. I got this one off ebay. http://www.ebay.com/itm/251538525763?_trksid=p2059210.m2749.l2649&ssPageName=STRK:MEBIDX:IT

Also curious if anyone offhand bought the same or knows off hand which model I have purchased.

[MTCB Android Head Units Q&A] sosferatu:
This can happen when you turn the volume to loud. The amplifier in the radio then goes to an anlternate voltage instead of a direct voltage or vica versa (that i cant recall)because the amplifier can't handel it. The result is that you blow/burn youre speakers. Thats why people with external amplifiers usually have overpowered the speakers. So they can't blow the speakers. Or at least less.

Sorry 4 my english. Hope you understand it

[MTCB Android Head Units Q&A] agentdr8:
I just got rid of my 07 350 Z, which didn't require any SWC adapters. I believe the Altima also uses the same 3-wire resistive SWC. You'll need to find the key1/key2 and ground wires that go to the stock headunit. On my Z they were all located together on one of the harness plugs.

According to PAC Audio's site, the pins you're after are on the 20-pin plug: pins 6 and 16 are your key1/key2 (shouldn't matter which is which), and pin 15 is the ground need for the loop.

You, sir, rock! Thanks.
[MTCB Android Head Units Q&A] agentdr8:
Keep in mind, that link was for the OEM base stereo. If you've got nav or BT, there are different plugs/wires you'll need. Just use the PAC site to determine which ones you'll need. Pick the SWI-RC product.

If u see the Picture of the back of your unit (ebay link), and compare it to the picture of the back in the PDF on Post #1669 i agree that u got the klyde. for safety go in the settings menu and get the info of installed mcu version. on my kgl unit, i can see "MTCB-KGL-VX.XX" in my software menu so i could identify it as a KGL. maybe u find something else with KLD (for Klyde)

new install bmw e53 x5

Hello all new to the forum

I bought this head unit and installed it no problem but it seems not a straight out of the box job

I have the unit with a 1TB 2.5in drive connected to it and all appeared fine but once I began to dig a bit deeper into the unit the following became apparent

1. As mentioned annoying base thump

2. The steering wheel control module of the soft ware does not function only the volume keys work and no assignment is available.

3. The on/off of the unit was inoperable and if the left control is pressed it brings up the amplifier controls

4. The unit is susceptible to the length of USB lead to allow the hard drive to operate so a short lead was used.

5. The button illumination does not work but colour can be changed so this may be an issue with the vehicle itself and not the unit.

6. The unit was rooted and this allowed me to remove the native music app and the navigation app

7. Google play and Tom Tom installed both work with their respective facia buttons and allow navigation sound to be heard when listening to music

All in all I am pleased with this unit the annoying elements are

illumination not working and the steering wheel control app not functioning

does anyone have any ideas on these two issues

Car Audio Service App? Safe enough?

Hi guys,

Been reading this forum for quite a while.

I'm from Portugal and I recently bought one of these Huifei to my Kia Sportage. Overall is good and working fine. I'm not an Android wizard so I'm not into experimenting rooting adventures and firmware stuff.

I've been reading that Car Audio Service app can solve the problem of using 3rd party apps to substitute native music player from this device.

If we install it are we able to use steering wheel buttons to go back and forward in music and increase and decrease volume?

Is it safe to install this app? Do we need to root the device in order to make it work?

I'm a numb and I'm afraid to screw it so please help me how to install and use the app as if I were the dumbest guy on Earth :o

Thanks in advance :good:

Radio App with name in counter fixed

Hi,

Some time ago I posted a variation of the Radio skin that showed the name of the station in the counter instead of the frequency. It did not work.

I have now fixed it. You can find it in post 860

There is a black and red version.
[MTCB Android Head Units Q&A] agentdr8:
You open the Car Service app and then use your steering wheel controls to display the keycodes. Then hit the Parameters (Settings? I can't recall) button and enter those keycode numbers for the next/previous lines.

Volume up/down should work everywhere, even without the CarAudio Service.

could anyone of those who biought the HuiFei directly from HuiFei please check the DTV-Connector inside on the board if there is a cable soldered to a pin internally connecting the pin to a - I think it was +5V - solder joint? I got the original HuiFei DVB-T here and now want to clear this before connecting and probably damaging it.

My Unit is a reselled one from Green Point and I hav such a wire in my unit. The pin is cut and instead of directly connected it's connected to that solder joint via a wire of aproximately 12cm length.
[MTCB Android Head Units Q&A] typos1:
Wow, how are they managing to sell them so cheap ! ??

Thats a HuiFei/KGL unit, you can tell from the back and the menus, GreenYi is re-seller, not a manufacturer.

2 things:

- I have the light controls working correctly with my car (e46) and the screen dims when I turn on the lights, but how do I change this brightness value? The settings menu shows it to be on full brightness when it isn't, so this isn't a representation of the actual brightness

- is it possible to set which sources are used? For instance I don't want to cycle past avin every time? Is this something xposed could help with?

Thanks
[MTCB Android Head Units Q&A] typos1:
Youve got a "GS" unit, "Hotaudio" retail these, some say they manufacture them, I dont think they do - the manufacturer will be a company with the initials "GS".

Have you read the first page of the thread that explains about the 4 types ?

There is also much discussion in this thread about all the manufacturers, types, MCU versions, how to identify your unit etc, do a thread search for more info.

The only fail safe way of indentiying a unit is by going into settings/about, it could be that the GS units have the same spec as the Klyde ones (as per the specs you posted) or it could be a lazy re-seller posting any old specs from a similar looking unit, we dont know until more details of the "GS" versions appear, or someone finds out more about them.

Fancy dismantling your unit so we can see who makes all the components ? !!
[MTCB Android Head Units Q&A] Ecniv_FR:
Multiple times as I was confused about the ID of my unit (Maybe I got a bit of information overflow :p)

So if I understand you correctly I got neither of those 3 and have no chance of flashing it to a proper firmware?
[MTCB Android Head Units Q&A] typos1:
It does say there are 3 versions and a possible 4th version called "GS" . . . (edit: you have to click on the blue link that says: "find out which version you have", further edit: I see there are only links to the KGL/HuiFei firmware on the main page, but pretty certain all 3 main types are available from people on here, still not sure about the GS type, again, do a thread search, pretty sure someone posted they had a v1.96 for those units)

I dont know if there are links to the GS firmware yet, the best way to check is to read the first page of the thread, pakidermo5000 spent a lot of time writing out all the info so people know all about the versions and firmwares etc.
[MTCB Android Head Units Q&A] Ecniv_FR:
It looks like the latest version is 1.9 atm I will try it in the morning I trust that the firmware from 4pda.ru is trustworthy?

Update for line-out functionality

Update news, all the line-out connector is working.

But I have to move two connector (as I remember its aux-in R & L), to Front Left out & Front right out. Detail wiring you can see in the top cover of the unit.

Now the unit is quite cold, only the display that will get warm for few hour usage.
[MTCB Android Head Units Q&A] sprfly:
Hello all,

I bought a KGL-7610 on ebay from the manufacturer. The main reason I bought the unit was because of the front panel layout which was suppose to look like this :

But when I got it it looks like this:

To me the AMS and LOUD button are worthless and I liked the fact that what I thought i was getting had the phone button. The buttons on the first picture seem much more useful and thats why I bought this specific one and actually paid a little more too. Besides that it was listed in the description that it came with mounting brackets and it did not. I tried to use the ones off the stock radio but they do not work; they hold the radio too far forward. I looked to buy some but had no luck; I can probably make some so this isn't huge but still they are missing. Also, the map card is corrupt. When i tap on igo it says i need the map card inserted and it is. When i pull down the status bar it says the card is damaged. So i cant use the maps. Also, when I briefly was testing it, it was a real pain to initially pair it with my phone through bluetooth. Once i finally got it paired and was playing music through it it sounded pretty good, except if you started doing anything else on it the music started "skipping" (for lack of a better term) a bit. It wasn't a constant a constant thing just sort of initially when you first start doing something else with it. Not sure if this is "normal" and just a software issue that is fixed with a firmware update or a hardware issue. Lastly, just like everyone else, my mic is horrible (according to the person on the other end, i haven't heard it myself). I don't know if its worth cutting my losses and just getting a full refund because the item was misrepresented or getting a large partial refund and just keeping it and working through the issues myself. That is of course as long as my bluetooth issue is not hardware related. What do you guys think? Thanks!
[MTCB Android Head Units Q&A] agentdr8:
There is no built-in capability to change the dimmed level. I can probably add a preference for this in my xposed module.

Yep. You can give my XposedMTC module a try.
[MTCB Android Head Units Q&A] Blaze Falconburger:
That's a shame - is this set at MCU level? Also the back light for the buttons come on with the lights but I can't remember if they do this before Android has booted or not. I tried the timer in Xposed which is a good idea for cars that don't utilise the illuminate pin in the wiring harness, but for those that do it would be nice to have just one control not two. Would be great if you could add it :)

I have been using your module since I got the unit - brilliant work btw :good:

Unfortunately I enabled override and made sure I deselected everything else as I only want radio and MP3, but DVD (and maybe one other also) appeared when cycling through. Does it need a reboot to take effect?

[MTCB Android Head Units Q&A] george2350:
Erisin sells a lots of make and models - Look at the specifications of the model you are thinking of buying and then check the first post of this thread which tells you how to find which unit you have. There is a PDF which illustrates the differences and how to identify the unit.

Yes, i asked for a picture of the MCU screen. Hope to get it soon. It looks like a HuiFei unit from the back. No fan so no Klyde i guess.
[MTCB Android Head Units Q&A] typos1:
You should be able to telll from the menus as well, sometimes the picture of the back is generic, the last time someone asked (yesterday) the menus suggewsted it was a HuiFei, but the back suggested it was a Klyde, TBH, it doesnt matter which version you get, theyre all as good or as bad as eachother.

[MTCB Android Head Units Q&A] jayvan:
I'd probably send it back...

The unit you thought you were going to get is the one I did get (off ebay). I really like the one I got and it seems to work fine; bluetooth paired easily and was able to import the phone directory and call from the HU; map was intact (although I use Sygic), same bad mic, though. Mine's running on 1.91 firmware. For some reason the carservice app doesn't work for me (yet) and also having trouble with the poweramp toast app working (probably something I'm doing). Good luck.

I've got my rear camera working now, I had connected the red signal cable to the wrong pink wire, once I connected it to the one from the head unit end then it worked. I've now installed a wireless receiver and connected the wire from the yellow plug to the pink wire going to the head unit and the red wire to the pink +12v feed from the canbus. The yellow socket labelled CAM IN was the correct one to use.

Do NOT buy anything from KEYLO or SHENZHEN KAI

Bought a KGL-7698N unit from Keylo. It arrived, worked for a week and then died with a squeal, taking out TWO of my speakers in the car. Ripped. I had upgraded from an older WinCE unit and I've installed a few in my time, never had a stereo take out speakers. In any case, I've been in contact with Keylo back and forth for weeks (since May 29) to resolve this issue. They said they would take the unit back, but I had to cover shipping ($70). I said that was ridiculous, they should be covering all expenses to cover a warranty repair for a basically DOA unit. They decided to ship a new motherboard to me. It arrived with duty attached ($27) that I had to pay. Take time out to uninstall the unit, take it apart, put in the new MB and bam, the ribbon cables are wrong. Contact them again, they want me to pay for shipping of the cables, their second screw up. I refused, they shipped it, arrived with duty attached again ($23) because they stupidly put a value of $30 on the package for a few ribbon cables. WTF? I'm furious at this point, damage to my car, time wasted, money wasted with duty fees. They'll issue a refund if I ship it back, but I feel they should pay the shipping. If I ship it back, I'm out of pocket $120 total, plus the cost to repair my speakers. They've now gone silent to my emails. I've issued a ticket with Paypal for resolution.

Bottom line, these people have an inferior product, there's been multiple complaints of the units and their support is pure crap. I'd HIGHLY suggest you buy your units from someone else.

[MTCB Android Head Units Q&A] xrapidx:

I'll most certainly stick to eBay in future.

What sort of problem are you having? Maybe I can help troubleshoot.
[MTCB Android Head Units Q&A] jayvan:
I was going to but was running late taking the dog in for surgery. Hard to think about other stuff right now. :(

The ebay seller was pumpkin_cool and the auction link is: http://www.ebay.com/itm/171369652040?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

We had a slight language problem but they made good on the sale and shipping was 3 days HK to the US west coast...

Actually, I don't know who made the HU. If one of you can tell me that would be great.

Also, a question: I'm assuming the xposed module for these units would work for me. It's been rooted and I had the same experience and Sir Sniffalot but the root is in place. I'd also like to change the dpi of a couple of the apps (like Google Play Music) but I've never done that before. Anyone have any advice/settings so I don't have problems...? Maybe I'm just being overly cautious. I haven't installed TWRP or made a backup yet. Wasn't sure I wanted to change the recovery.

Still haven't gotten the carservice app to work right for me although it finally showed me the codes. I did go to parameters and input them but still not working. The SWC and faceplate next/previous buttons had the same codes. Is that the norm?

Thanks to everyone who have shared and helped the rest of us. :)
