[MTCB Android Head Units Q&A] agentdr8:
If the Huifei receives 12V constantly on the switched ignition input, it will drain your battery within hours. They aren't really designed to be instant-on like stock headunits. The units do have a capacitor of sorts, and will stay powered for roughly 30 seconds after key is out of the ignition.
[MTCB Android Head Units Q&A] 1-2-Hak:
Dont totally agree. When the unit goes into standby it draws a lot less current. I have confirmed on here that some of the Canbus users units actually go into this standby and quickly resume with out totally powering off.
[MTCB Android Head Units Q&A] thongy:
Hey, optx, thanks for the info...it did work but only after 4-5 times. After the 5th time once I shut the ignition off, the headunit stays on.

When you removed the plug, was the head unit still powered on or did you power it off? Pretty irritating...I also contacted the seller to see if they can help.

Edit: Nvm figured it out. Thanks again optx!
[MTCB Android Head Units Q&A] agentdr8:
But from standby can they resume full power with the key out? I would think that's no different than holding the power button to "shut down" the unit but have the key still in. If you hit the power button again, it comes right up. It doesn't ever seem to power off when it sees 12v on the switched input.
[MTCB Android Head Units Q&A] optx:
I know that some devices have a mapping problem after flashing to 1.86.

I read the thread, but i did not find a solution. I even took the zip with the keys that are posted here and replaced them, did not work on my end.

Thats why i asked the question, if it is only me who can start the GPS app like this, since i am still trying to figure out a fix for this.
[MTCB Android Head Units Q&A] matas2007:
Can anyone else confirm this? No ignition = no radio? :(
[MTCB Android Head Units Q&A] kwalsh24:
I'll confirm this, its an issue I have with my radio as well with it being installedin my 09 VW jetta. I have narrowed it down to the canbus unit itself, and I am in the process of ordering a replacement harness of ebay to wire in a different canbus adapter that will hopefully fix this issue. My seller kept telling me I didnt need the canbus adapter/decoder as I didnt have SWC, and that I was to use the bypass wire to wire the radio into my car, which everyone who has a canbus system in their vehicles will know that this isnt the way to do it as the radio will be on constantly due to the no 12V accessory switched line.

My canbus turns off the 12v red accessory line after 30sec-1min of the key being off, but in the ignition, and will turn the power back on to that line (again for 30 seconds to a minute) whenever it senses activity in the canbus system, i can turn the radio on with a touch of a power window switch, or a opening of a car door, I hope with the removal of the stock harness with the installation of the harness I am going to assemble with my axxess canbus decoder that this will solve the issue. My first attempt at doing this didnt start so well as I ordered the wrong harness, I did find one that looks fairly close to what my radio uses, mind you its going to take a bit of re-wiring.... If anyone is interested, heres the ebay link to the harness...

http://www.ebay.ca/itm/281376674556?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Anyone have any updates from the manufacture if they are working on a release to fix the issues in 1.86? Has anyone reported the issues to their seller who is in touch with the manufacture, as mine clearly isnt, as he wasnt even aware of the 1.86 release.
[MTCB Android Head Units Q&A] xrapidx:
Just got the outcome of my PayPal claim, ruled in my favour, assuming the seller (Hanker Yu) has funds in the account used (heyati2008@163.com).
[MTCB Android Head Units Q&A] kwalsh24:
Thats good news, lets hope it wasnt a fly by night email account tho :( I dislike how paypal uses that method, as normally the accounts are drained as soon and any funds are entered into them. Last time I had a claim end like that I only received 1/4 of what I sent. Are you having to send the unit back or is it yours now to keep?
[MTCB Android Head Units Q&A] xrapidx:
Looks like I keep it, although I'll send it to a electronics place to see if they can sort it out, I'll also order the radio module before then, so its probably going to end up costing me the same to have it repaired :p

Thought I'd be able to live without radio, but streaming is costing too much.

I'm also curios to see if it was a fly-by-night account, if so - I'll contact my credit card company.
[MTCB Android Head Units Q&A] Blaze Falconburger:
Has anyone found a VNC server that works on the radio yet?
[MTCB Android Head Units Q&A] blankers:
I was looking forward to trying these...thanks for posting.

With your previous versions I was able to install them alongside the existing app, but these won't install normally. It says something about conflicting signatures....can you fix this so I can try them whilst retaining the old radio app?
[MTCB Android Head Units Q&A] typos1:
I know youre pretty experienced with this problem kwalsh24, but just reading your post and the other 2 people that are having trouble like this makes me think its something to do with the car rather than the headunit.

Different manufacturers have different set ups, some let you turn on the stereo with the ignition off, some dont, some do but will kill it after a set period of time to conserve battery, its just sounding like Audi doesnt allow it, its not sounding to me as anything to do with the unit.
[MTCB Android Head Units Q&A] kwalsh24:
I think what of really comes down to is the programming of the canbus decoder and the compatibility of the decoder itself. I've had 3 different radios in my car, 2 with one decoder and now this one, this decoder is the only one that I've ever had it where it didn't maintain factory style control. Thus why I'm removing it. I think its really the only way to solve the canbus issues, is to replace the crap units that come with the radios, and use a legit unit that's compatible with the cars that the radios are being installed in, as they are basically little relays that either are or aren't fully compatible with the vehicles main ecu.
[MTCB Android Head Units Q&A] mikejclark:
I'm getting closer. I hadn't connected the pre-outs. Once connected I got sound from the rear. Although it sounds like only the sub. I need to do a little more investigation into how the speakers are configured in my car.

Facing another problem now with the installation. The unit came with two metal brackets which look like they should bolt to the sides. But they're not a good fit and they don't line up with the slots for the removal keys. Is this how you attached yours?

[MTCB Android Head Units Q&A] krustymk:
Hi guys

My unit came with an app to use the Ford factory bluetooth called SYNC.

If i install a custom rom i presume i would lose that app? If so does anyone know where i can get it from?

I can also confirm the AF bug here in the UK, BBC Radio1 uses multiple frequencys and the unit does not change to the stronger signal when out driving about.

Does anyone know how to force the radio to remeber the preset stations after a reboot?

Thanks

Joying quadcore

Still enjoying my new amazon toy. As others have mentioned these things are mostly empty on the inside. After several hours with a heat gun, I was able to mold the double din Metra fascia to be able to fit the Chinese size, and it looks great mounted.

Here arises my new problem, it has a great viewing angle from straight on and above, but when viewed from below, the picture is quite poor. I have gotten the most tilt that I can, but with my dash it is always going to have a slight upward tilt, meaning I am viewing the picture from below horizontal.

before I remodel the entire dash of my truck, I got to wondering. Could I mount it upside down, and use a software setting to flip the screen? Or potentially, could I just flip the LCD itself, and use such an app?

Shame that the viewing angle is so poor from below...
[MTCB Android Head Units Q&A] aromig:
I tried searching on this, but came up with nothing. Has there been any discussion on integrating the Cyanogenmod Theme Engine into the custom Roms for these units? This is one of the last remaining things I sorely miss from my android phones/tablets that these don't have. I've tried the themers available for xposed, but they don't do much (if anything).
[MTCB Android Head Units Q&A] vipergrm:
Has anyone installed a second monitor to this unit? My car has an existing DVD player and screen with an AUX input. Is it a simple matter of running video/audio phono leads into the DVD unit? Presumably it will output the same picture. Thanks
[MTCB Android Head Units Q&A] pants001:
How good is spotify in the car!

Are you using the xposed module for spotify......by default these units appear as a phone (not sure why) and limited skips and only random album play

Install this

http://repo.xposed.info/module/net.madnation.sskip

to get your HU to correctly report as a tablet....now unlimited skips and you can play album tracks in order

Nearly all the popular units have two composite video+ left/right audio outputs designed to drive external displays in headrests etc...
[MTCB Android Head Units Q&A] grahamwright1:
Only output's a video signal when you are playing a DVD on the head-unit, and does NOT mirror the normal display to the Video1 and 2 outputs. I just installed a JY into a Honda CRV and added a pair of headrest monitors - the kids love it, but it would be nice if all video could be mirrored.

How about MCU KLD2 V2.75 that a member had..Is is somewhere uploaded to give it a try?

That has to be firmware dependent... I don't even have a DVD in mine, so what is the point of the outputs??

No bluetooth sound

Hello,

I´ve installed Malaysk update_4_4_4_1024X600_6_RK3188_MAL_13_08_2015 on my device.

After the installation I have no sound when I make a bluetooth call, streaming over bluetooth is ok and I can be heard.

I tried different phone, but none works.

Is there a setting to change?

Regards

Thomas
[MTCB Android Head Units Q&A] javlada:
What do you mean by "set keys"? I never had to set up anything else then the CANBUS setting.
[MTCB Android Head Units Q&A] chipyy94:
I mean that you go to setting in radio and set which button will do something.
[MTCB Android Head Units Q&A] javlada:
This never worked for me. In this setting the unit never recognized any button pressed. But I was able to change volume, skip tracks or change music source (radio/poweramp/DVD) by my steering wheel controls.
[MTCB Android Head Units Q&A] Rackers:
Hi all,

Installed latest Malaysk ROM. Everything looks fine but the unit seems to have pulled all my contacts (including email addresses, etc.) and is also showing them with last name first when it should be first name first. Any ideas how I can get it to display correctly and only display phone numbers?

Thanks
[MTCB Android Head Units Q&A] markusmuster:
Really nice work! Thank yo a lot!

I Just installed this FW on my (brand new) RK3188 (1024x600).

Perhaps (aeh, well probably) I'm missing something... you mention " If someone does not like the style of JY..." : Which App should I download? I cannot find it. I would prefer the original pure Android Style (a much better sized Volume slider) if possible.

When I try to start "MyVideo" the UI seems to crash and the bootlogo is displayed forever. This is probably a bug.

According to this link there's a newer version available. Sep. 3, 2015. DL Links inside post. http://www.carjoying.com/Joying-blog/12.html​
[MTCB Android Head Units Q&A] nixfu:
How long does it usually take Malaysk to release firmware for other versions. I saw that he released a Sept update for the dual core 800 models only.

I am not complaining or ungrateful, I already threw him a donation and will probably send another.

I am just curious.

I will try on next week the converter's solution with my car. Unfortunately where I'm living, the receiving of DAB+ isn't yet. But I go next week to Budapest, where can I receive DAB+ broadcasting.

My car has fakra (SMB) female connector of the FM aerial, whitch mounted on the backwindow in horiziontal position. This aerial make very good receiving with MTCradio app. I built SMB splitter: http://www.ebay.com/itm/271217077477?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT

I connected one port to the aerial, one port to the input FM connector of the HU, and last one to the DVB-T/DAB receiver with adapter:http://www.ebay.com/itm/220952686253?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT

The FM receiving with MTCradio app doesn't be weaker. The above solution doesn't lose signal.

I'm afraid, that the DAB+ receiving will be weak, because usually the DAB+ broadcasting is vertical polarization, not horizontal.

I think we have to buy this:

http://www.aliexpress.com/item/TV-a...a-with-Amplifier-special-SMA-F/868246493.html

And we have to mount in (near) vertical position:

[MTCB Android Head Units Q&A] jamieb122:
Nope, I use USB debugging....that being said is your device rooted? If not use the facotry password *#hct#root# to root your device. From there install a terminal emulator on your device and do the following:

su

setprop service.adb.tcp.port 5555

stop adbd

start adbd

then you should be able to do adb over wifi (no usb needed). On your computer (not your device do the following)

adb connect <ip_of_headunit_on-wifi>:5555

adb shell

Let me know if that doesnt work
