I think that's similar to another post a while back that pretty much confirms that when the HU isn't fully shut down, the internal amp most likely is still on, and vampires power at a pretty steady rate.

SDRTouch works fine for usb-based RTL devices. The onboard tuner is not RTL-based though, so it won't work with that. I use SDRTouch on my GS with a usb RTL-SDR device hooked up to my vehicle's antenna. Works well enough, but definitely not as "integrated" as the MTCRadio.

No. The time parameter is an integer, and there is no title variable that's being set. Within that method though, you could set a local string variable to the result of getMusicName((String)music_list.get(currentPlayIndex))), which should be the title of the current song. Now that I look at it closer, the intent is received by MTCCanbus, and then the integer parameter extras are pulled out, and sent to specific source-based methods to then be displayed. All of the parameters are expected to be integers, and the resulting methods only seem to convert those integers into specific bytes for displaying, so to display strings, it would have to be converted to specific bytes first. This is probably something beyond the scope of smali editing; it would definitely be easier to accomplish this in java using reflection or xposed.

Most likely not going to work with the built-in BT adapter/stack, as its implementation isn't the same as standard BT in most android devices.

Erisin ES9405A 8" HD Android 4.4 no sound but radio and DVD ok

Hi all,

I want to share my brand experience and ask support to the community

I bought an Erisin ES9405A for my volkswagen and after just 1 week some problems come out.

Most important trouble is that there is NO AUDIO from music and USB/SD source (GPS slot or MM slot is the same: no audio) and NO AUDIO from video source (mute video displayed).

If I choice radio or DVD the audio works great.

Is it possible that this units have 2 separate amplifiers?

I for sure tried a reset but I can't fix the problem. I think it could be an hardware problem but I'm not sure because as explained radio and DVD works fine.

I'm trying to fix myself because Erisin support is the worst of the entire world and they are gaining time with no answers to my support requests or pretending to not understand what I'm saying via Skype. But you see, if you want to give them your money they understand very good! Oh if they understand.. babylon was noobs in front of these chinese when you speak about money!

So I can't ask for support to this ****ty Erisin brand also if I bought just 1 week ago!

I would not recommend Erisin as reseller due they are very incorrect and the support is inexistent, stay away from this brand, I warned you.

I come from a same radio EONON GA5153V that I loved but I changed (in wrong) with this erisin just for display resolution (erisin 1024x600 VS EonON 800x480). I can also compare quality: EONON has got better buttons quality and feeling and higher responsive touchscreen (with erisin I often must touch more than 1 time the same place to do the action: frustrating).

Also the Erisin CAN-BUS module doesn't work well: it turns off the radio pulling out the car key but it don't display door status on the unit. No way to fix it in factory options. EONON worked fine instead :(

Also the Reverse camera input doesn't work at all in my case but others video input works great. Unfortunately I would use the reverse camera input because it should display images when the reverse gear is on (the rear camera is powered by the reverse light) but I can't due this Erisin totally sux :(

I do not want to trash my unit for now: I can fly over CAN BUS not working and over reverse camera that I connected to a normal video input (I must manually switch input to show the camera) but I really can't use this only with radio or DVD also because I do not use an optical support since over 2 years!

Any idea or suggestion to fix this "no sound" from some source of this chinese Erisin bad unit?

Thanks a lot for your understand and for your help!
[MTCB Android Head Units Q&A] xrapidx:
Looks the same, only seems to be application updates, and bug fixes (e.g. a Bluetooth menu in settings)

I have had my volume control knob stop working once since the update, had to do a reset - not sure if its related to the new software, or just a once off bug.

Any 8-inch Universal units out there?

Has anybody found an 8" Universal unit with Android 4.2.2? I'd like to see if I can install one in my 2007 Tundra using the Alpine KTX-TND8 Dash Kit.

w_ww.alpine-usa.com/product/view/ktx-tnd8-2007-2013-toyotatundra/

It would be nice to find a unit with or without DVD... don't really need DVD these days.

Anyone? I've searched and searched... lots of 8" units for specific vehicle types, but nothing universal that may fit my Tundra using the Alpine kit.

Thanks for any info or advice.
[MTCB Android Head Units Q&A] typos1:
There are some AN21-U variants available without a dvd drive, not seen any Rockchip based ones that I can remember though.

You prob wont find any universal units that big, as the screen would fit outside the normal dimensions of a double DIN opening and this is only feasible on versions made for specific cars.
[MTCB Android Head Units Q&A] xrapidx:
I'd also like confirmation on the external mic, don't want to order one if it doesn't work... My internal mic is useless... People can hardly hear me, I have to scream :p
[MTCB Android Head Units Q&A] mikejclark:
I'm eagerly awaiting delivery of a huifei for my Audi A3. Ordered from kaigele on AliExpress.

Spotted this obd2 bluetooth reader for a good price on Amazon:

http://www.amazon.co.uk/gp/aw/d/B004KL0I9I/ref=redir_mdp_mobile?redirect=true

Anyone know if it will work with a huifei?
[MTCB Android Head Units Q&A] bbq-allstar:
The only thing about the Alpine "Perfect Fit" Dash Kits is that it allows for an 8-inch screen unit that is double din to fit. Basically, using this kit will allow me to install an 8" unit as long as it fits "ok" in the nose because the chasis is the normal 2Din size (178mmx100mmx164mm). The nose opening of the Perfect Fit kit is 190mmx121mmx22mm. So if I find a unit that fits in the nose area of the kit opening, then I think it will work.

However, the question is whether I can take one of the 8" HuiFei units (KGL-8401, KGL-8102, KGL-7668G, KGL-7303) and have it wired and make it fit... I guess I need to explore the measurements of those units...
[MTCB Android Head Units Q&A] R4D3N:
I still have a problem with the unit not wanting to mix sound between GPS and other apps after restart.

If I start the GPS it doesn't mix the sound only if I uncheck and check again the GPS Monitoring box.

I installed CarService but it doesn't work. What can I do?
[MTCB Android Head Units Q&A] kwalsh24:
I still have the problem where my Gps sound is faint when mixing, and well now its back to the switching mode (even tho mixing is set)

Hoping the update that was mentioned earlier will fix this.

Sitting at the drive in now, sucks having to have the key on to have a radio lol, oh well
[MTCB Android Head Units Q&A] xrapidx:
[MENTION=4036493]kwalsh24[/MENTION] not sure if you've done it, but you can set the mixing volume in the GPS settings.

To both of you, I've found that it depends on the GPS software I'm using, iGo cuts out, Google Maps always works fine.
[MTCB Android Head Units Q&A] kwalsh24:
Yeah I have the mixing volume set to Max, may have to try Google maps and see how that works. Just would have to download all the maps for offline use
[MTCB Android Head Units Q&A] xrapidx:
I've found google maps works best for me, but I'd still need iGo for offroad maps.

Btw, still waiting for permission to upload firmware.
[MTCB Android Head Units Q&A] typos1:
The wires are all the same, so that will be no problem.

You just have to spend some time searching for one that you think will fit.

Why you want a bluetooth one ? ? ! !

Unless you intend to remove the stereo from the car and stand 10m away from your car, holding it in your hand whilst using the OBD functions on it, then Bluetooth for OBD is totally pointless - a usb to OBD lead will give you a better and faster connection with less errors, it will also be cheaper because it wont contain a transmitter that you dont actually have a use for. Bluetooth is designed for devices that are portable, this stereo is not. Wired ALWAYS gives a stronger signal and is faster than wireless
[MTCB Android Head Units Q&A] mikejclark:
Good point! Hadn't considered that.
[MTCB Android Head Units Q&A] xrapidx:
The new version seems to have changed a little, it now remembers what application you had open, and on startup starts it. Previous version only seemed to do that with radio, music and Bluetooth.
[MTCB Android Head Units Q&A] R4D3N:
Can someone upload the latest firmware in English? I believe it's v1.86.

How do I set the wireless display? I want to connect my iPhone to the unit but I don't know how. How can I use AirPin Pro and Wireless Display?
[MTCB Android Head Units Q&A] ffwd4490:
I had the same problem. The remote turn on lead (power antenna) only gets power when you use the radio. so your amp(s) may not be turning on if you use say Spotify or another web based music service. This is what was happening to me, so i gave up on the radio sending the turn on signal to the amps and simply used a switched power lead from the car itself. Hope this makes sense for you.
[MTCB Android Head Units Q&A] ronnieeeeeeeeee:
How did you manage this? Connect the remote turn on wire to another wire that gets power when the stereo turns on? Such as the red power wire? If not this, then what did you do to fix the issue? Thanks in advance!
[MTCB Android Head Units Q&A] ffwd4490:
Yes, I used the red wire to the aftermarket remote turn on lead of my amps.

Good news !!!! On my firmware running to sleep on the devices GS with MCU 2.45 !!!

[MTCB Android Head Units Q&A] ronnieeeeeeeeee:
Awesome. I'll give it a try before long. For now with the new amp control wiring changed up earlier, this HU sounds ten times better. Initially, I was missing my old Alpine unit - now - this one is really comparable but with ten times the feature set.

Anyone have any leads on making the steering wheel controls work? I have the idatalink Maestro RR module, which is supposed to make steering wheel controls work - but they do nothing on this HU. I've tried mapping them, and even set the CAN BUS option to no in the factory settings menus. Maestro has you flash a module which changes certain things based on the HU you have (These android units aren't an option), I've tried a Pioneer deck so far. I'm going to flash another few soon to see if this has any effect on the SWC. Is there a wire I should have hooked up? The two "key" wires are unused in my current set up.

---------- Post added at 08:31 AM ---------- Previous post was at 08:26 AM ----------

I have the Eonon G2110ZV (KLD RK3066) unit. I've tried flashing your rom a few times with no success. Had to go with the other option. Any ideas what I might be missing or messing up? It always fails in the initial install, despite having the proper .mcu... I've always attempted to do it with the next launcher.. do some units not allow this new launcher? Any help/insight will be great. :)
[MTCB Android Head Units Q&A] devilsoft:
Not on all firmware. I use coudu KGL rom from 15 Jan 2015 and that has no busybox installed. I needed to install it manually.

I didn't test newer firmwares though, so you may be right :)
[MTCB Android Head Units Q&A] Krisjan89:
You need go hook your swc up to at least one of the two key wires, otherwise you have no connection. Out of curiosity, how is that maestro thingy hooked up to the Hu atm?
[MTCB Android Head Units Q&A] ronnieeeeeeeeee:
Thanks for the key wire info.. I had read around and thought maybe they had something to do with it.. now to find out which wire to connect one of them to lol

I have a 2012 Ford Fusion with nearly useless Microsoft Sync (factory bluetooth/USBs/AUXs, etc.) and when it works it works well.. but it rarely works... so in order for me to hook up an aftermarket unit and essentially have it be as painless and non-invasive as possible - I needed to use expensive harnesses. I chose the iDatalink because it seemed to be the most intuitive. The Maestro RR module is the centerpiece of my entire aftermarket harness. This, combined with the FO1 harness made by iDatalink connect to my factory wiring harness. In short, the Maestro is a go between for the headunit and car. These two pieces connect into the car and into the head unit wiring harness as well. I see my key presses light up the maestro module, but do nothing on the headunit. Hopefully connecting one of the key wires will do something. I will use the remote wire add on first and hope to get somewhere with that.

Thanks for the help again!!

Thanks for your reply.

I already tried to check the Factory Settings (password 126) and all audio settings are ok (set all to 10 but BT to 15).

Is this unit equiped with a separate amplifier module for radio and DVD and another module for mmc/usb ?

It's not a matter of trust :) I just say that busybox is not present (or is broken) in that firmware.

[MTCB Android Head Units Q&A] naghtan:
Well, I just want to tell about the experiments with MCU... From the beginning, I cant get out info from the unit, just I can make that radio recognise buttons from wheels when the option Canbus : NO.

I thought the problem was from MCU KGL version the unit had, it became with KGL5, and the car is Mercedes W211... then I try to change it for the KGL1. I try many version, and right now I on KGL1 v2.53.

The Canbus box have a sticker say B200, when I choose B200, both options, the buttons from wheels stop working... It is my canbus working? It is normal? Can I get more info of any way? Could I get info in my main dashboard car?

G'Day all,

Just wondering if someone can help me, I've read every post in this thread over the past few weeks, and just did a search, but can't find an answer to my question.

I have a Joying 1024x600 RK3188 HU, running Malaysk's latest firmware (thank you heaps mate). I have a 4 port USB hub powered through my car with a 12V to 5V stepdown.

I cannot seem to get it to mount more than two USB sticks in the hub. One USB I am running my ECUTalk USB cable to my cars ECU, another has FLAC file audio files on it (running Viper and PowerAmp (sounds great)) But I wanted to put a couple more USB sticks in the hub for more music or vids.

Is it a limitation of the HU that no more than two USB storage devices can be mounted? Or is there somewhere I can edit to allow the system to mount more USB storage devices?

Thanks,

PanterA ... Forever Stronger Than All
[MTCB Android Head Units Q&A] Malaysk:
Sorry, I do not understand so well in English, can someone else you will be able to answer? ;)

Yes, you can use no more than two devices. Eating them is still not enough, even though you and is a hub with additional food

[MTCB Android Head Units Q&A] i.draskovic:
I'm not sure is anyone familiar with boot problems, but I have uploaded video.

I have write e-mail to seller, and seller has told me that HU update has failed and she send me links to download files and to try to re-flash HU. I have KGL4 device, but she has send me KLD firmware. I have try that, but I have same problem.

Buttons (keys) does not work. That means power, menu, band, dvd, eq, navi, eject, reset, set, mute, play, loud, ams does not works. Only volume up/down and tune up/down works.

I have to use usb keyboard that I can select option in bootloader, and than HU boots fine. When I shut it off and try to start, it is always same.

Is my RK board damaged so i have to buy new one or is it any solution to make it to boot normaly?

So just to verify that it is for all for all MCU's, this comment on your firmware for the 800x480 RK3066

Does not apply to the sleep mode on 1024x600 RK3188 firmware ?

[MTCB Android Head Units Q&A] Malaysk:
Everything will work as usual. Only sleep after turning off the machine runs on the last MCU. I got only KLD 2.55. For others MCU it is necessary to ask the sellers.

Ah ok, so it isn't for all MCU's in that sense.

That would have been the main reason for me to apply your latest firmware, but I will not worry about it until I can use the sleep after turn off on mine.
