Guys

Anyone in the Uk (or Europe, for that matter) looking for one of these units should have a look here: http://www.bmwradios.com/

I know the company from the Rover 75 and ZT Club. Company rep Sean Moore (AKA Radioguy) has been on there for over 4 years and gives excellent service. Have a look at the Double Din section, they pretty much dominate things there.

The E46 version of this unit was recently introduced to us there by Sean. This units also fits the Rover 75/MG ZT with some minor modification - thats why we have it.

I'm pretty sure that Sean could also source other models of this radio in addition to the E46. All units are shipped from the UK and there is also a repair depot in the UK so no customs duties, shipping back to China etc.

Sean also provides a trade in facility. I must be on my 6th at 7th DD from him at this stage, all traded up for a newer model.

ipod wiring / usb digital tv

Hi folks!

Recently I was got an joyous unity with full touch screen and android 4.4.4. This is an excellent unity! I´ve installed wase, youtube, spotify, tunein, soundhoud.. and all sw works well!

I´ve searching some answers to my question but i didn´t find it. Can you help me in some doubts?

- This unity didn´t come with ipod connector. I enable this function in the secret menu (pw 126). But in 3 sec the ipod sw auto close by its self. I´ve connected a classic ipod 160gb on 2 USB port but i have no success. I think that there is a specif conector to ipod. Somebody knows if I open the unity to put this ipod connector.. it´s easily? somebody have wiring diagram? I must have to solder? Or just fit in?

- Somebody knows if an USB digital tv receiver (works on smartphone android) works in this unity? Or there is an component to fit in this unity that works with Digital TV sw enabled on secret menu?

best regards!

Video output question!

Hi,

I have been reading a lot this thread and i found some very usefull information, so congratulations to everyone that has contributed. I recenlty installed an EONON G2110 unit which basically has the same specs as the ones described here. I rooted the device but have not installed any firmware since the one it came with, is working without issues. The only problem I have is with the video output of the device. I have connected two rear monitors for my kids to watch a movie. When I insert a dvd into my unit, video shows fine in the rear monitors. However, the same movie only show in the main unit's screen when played from a USB stick. Has anyone had the same issue? Is it resolved using the firmwares provided in this thread?
[MTCB Android Head Units Q&A] typos1:
Hmm strange, maybe it is the decoder, hope you paid on credit card so youre protected if their response continues to be bad.

(I got the A9 bit and edited my post :) quadcore ones are A9 as well)

Great, a few people have had similar problems, what make is your unit, can you post some pics to guide others ?

A USB TV device should work (the reception wont be good when youre moving as there are only single tuner Android TV devices available), as long as you use an OTG poert, but I dont think JY units have one. There is what looks like a port for an internal TV card on the motherboard but its different to the Klyde one and no JY sellers seem to offer built in TV, only external boxes. Most JYs come with an ipod connector hardwired to the motherboard that sticks out the back, which JY unit have you got ?
[MTCB Android Head Units Q&A] pbiggane:
Hi typos1, yes I'm thinking it's the decoder. What are your thoughts on me purchasing an aftermarket decoder, like the one made by Connects 2? Do you think it would be seamless with the Headunit? Also, while I was looking through the running apps, I noticed there is a canbus app running in the background, is this something that I could update to the proper canbus? On my oem quadlock, there were two cables that appear to be fiber optic, but maybe they're for the canbus? These cables are not hooked up anymore as there was nothing to hook them to on the new HU. Also, the "amp con" wire and " illum" wire from the Witson HU are not hooked up, was I supposed to connect these to something? The illum works if I hook it up to a 12V source, but oddly if I disconnect it, the illum comes on once in a while when I the car's lights automatically come on at night (the illum doesn't always come on, and sometimes it turns off by itself). Lastly, should the canbus have it's own power source? There is a yellow wire labeled "batt", but the HU appears to work if it's not hooked up to a battery source, I've applied a fuse to the wire and tried it with being attached to a 12v source as well as not being attached, the HU seems to functions the same either way with no difference to the canbus. I've attached a photo. Not sure if it matters, but I had the BMW professional HU originally and I think the factory system was a logic 7 based on the fact that there appears to be fiber optic cables and I have the tweeters in the doors, but all the speakers work right now with just the aftermarket harness hooked up.

*on the attached images, I've circled what appears to be fiber optic cables, I borrowed this image from google search, my connector is the same except I don't have a fuse in mine and there are less pins on the bottom of the connector.

Great, thanks, but that screw appears to be touching the BT card, not the wifi ?

Can you psot pics or a link ?

---------- Post added at 02:22 PM ---------- Previous post was at 02:12 PM ----------

Some people have got a different CAN Bus decoder and that has sorted their problems.

Different car control apps appear depending on what CAN Bus setting in factory settings it set to, not all makes are supported, BMW usually is, what CAN Bus setting is yours on ? What unit have you got ?

Most CAN Bus cars have CAN Bus Tx/high and CAN Bus Rx/low, so those fibre optic wires could be for CAN Bus, usually they are routed to the CAN Bus adaptor AFAIK, you could try hooking them up to the headunit, as its though (but disputed) that the headunit does all the CAN Bus stuff and that the adapter just gets analogue signals out of the CAN Bus system. There are 2 sockets on the headunit for CAN Bus, there is a post which points them out, at least for KLD versions, theyre likely to be unused sockets on the main connector socket on the back of the headunit.

CAN Bus adapters usually also get the amp con and illumination signals from the network and convert them to analogue then send them to the headunit, so I would expect them to be connected, there has been some discussion about the illumination wire on Beemers before but I cant remember all the details, using the thread search should find them, I d have a read.

I think its usual for the CAN Bus adaptor to also get power from the CAN Bus system and then send it to the headunit.
[MTCB Android Head Units Q&A] kjettern:
Yes It's touching the BT card. But like I said, don't know what did the trick. Only my wifi works again. I'm suspecting some sloppy solder job, so maybe it was some of the solder spill that shortcutted the wifi chip?
[MTCB Android Head Units Q&A] DJCannonball:
ok, it's 30mm x 30mm, it needs 12v

it needs to be quiet.

i haven't opened mine up yet (waiting for permission of my seller)

i want to order the fan in front.

what else do i need to know? where do i connect it to? can you send a pic of the connector and point out what's +12v and GND?
[MTCB Android Head Units Q&A] typos1:
Lol, I already posted the dimensions yesterday.

Bearing in mind that nobody else without a fan has this problem I dont think it will help, return it for a new one.
[MTCB Android Head Units Q&A] DJCannonball:
Yes you did post the dimensions yesterday, but i was asking for where to connect the fan (+12v and GND)

you mentioned no other fanless models have the same issue as i do, but read #10580 again, Echudoba had also a spinning android logo that stops, couldn't even complete booting.

i still haven't got any reply from my seller (probably due easter).

gotta have a little more patience.
[MTCB Android Head Units Q&A] typos1:
I also posted the location of the fan connector yesterday.

Echudoba has a totally unrelated issue to yours and he has a different processor.

The fan is not going to make any difference to your problem, your unit probably needs to go back and be exchanged. Have you tried a factory reset ?
[MTCB Android Head Units Q&A] DJCannonball:
yes i did, hard reboots and factory resets don't prevent the unit from overheating ... unfortunatly

Echudoba's cpu might be different than mine, but still .. same fanless housing, same manufacturer, same symptons i'm pretty sure it's the heating

on the other side you might be right but i hope not ;)
[MTCB Android Head Units Q&A] peti007:
I reinstalled my head unit's software today. I have a Mazda 3 specific Klyde one.

Installed Coudu's v4.2 4.4.4 image + KLD 2.40 MCU.

When I installed all apps what I use, I had the black screen issue again. I made an Android Factory reset then no black screen. I started to install apps one-by-one. The only what is not installed yet, is the ScreenFilter Xposed module. I use Twilight and no issues... knock-knock.

I use XposedMTC with MODE override. Default player is Poweramp and the Radio is the only what selected on list. The Mode button switches between Poweramp and Radio. This works OK. But when I switch from Radio to PA, the media keys (NEXT/PREV) works OK with PA, but in the background controls the Radio too! When I switch back from PA to Radio, not the last channel is selected.

Is there any way for Poweramp to resume from the last position after head unit boots? Poweramp opens, the last song is selected, but at 0:00 and paused, I have to tap the play button. In PA settings I checked the resume after start option.
[MTCB Android Head Units Q&A] agentdr8:
Rear video only works with the DVD player. The MCU controls video (and audio) output, and Android doesn't natively support DVD drives. The DVD app integrates with the MCU to get the video out. No amount of firmware flashing (OS or MCU) will change this behavior.

---------- Post added at 10:08 AM ---------- Previous post was at 10:03 AM ----------

Hmm, I'll have to check the key handling when Radio isn't active. I think I can also fix the resume issue; it might be sending a "stop" instead of a "pause" when switching sources, and that's resetting the current song to the beginning.
[MTCB Android Head Units Q&A] peti007:
Dear agentdr8,

Thanks for your help and hard work! When switching sources PA resumes from last position, that's OK.

My problem is if I stop the car while PA plays music. On next start HU boots up, PA loaded but with the last song from 0:00 position and not resumes playing, I have to tap the play sign on the bottom-left corner.
[MTCB Android Head Units Q&A] typos1:
A fan will help with cooling but if its overheating so bad as to cause your problem then it wont really make any difference, a heat sink AND a fan would help more, but then this thread would be littered with posts like yours and it isnt plus KGLs and JYs have not ever had fans, no units have ever had heatsinks, I really think youre fitting a fan is going down a blind alley, pretty sure the unit is faulty.
[MTCB Android Head Units Q&A] agentdr8:
Do you have the option in PA set to resume music on start? Should be under PA->Settings->Audio->Audio Focus
[MTCB Android Head Units Q&A] peti007:
Yes, I'm pretty sure, but will check tomorrow.

My musics are on USB. This could be the problem? This was with the non-rooted factory fw too. I thought it needs XposedMTC or Carservice. I've already ordered a 32GB SD card for music library, I'll see it solves or not. I don't use install-recovery.sh early start yet.

Oh I see. Yes, that makes sense that it would have issues if the underlying storage isn't available yet. My music is all stored on microsd card, which is available pretty much as soon as the headunit starts up. I've got PA starting via install-recovery.sh and it auto-resumes playing from the last spot, so that might be the reason why.

Update on my Hang up issue with KLD RK3188.

Mine hangs during the spinning android only on start up occasionally (no heating up is involved). 1 in 10 maybe. Except for some wireless issues works great. The seller sent me new firmware today. It upgraded my MCU from 2.22 to 2.42. Update.img was the same date. It did not fix my issues.

Boot up times are now 23 seconds from key on to the home screen. Firmware may have helped this.

I'm going to request an exchange from the seller as I really like this unit.
[MTCB Android Head Units Q&A] typos1:
We never did get to the root of just why exactly USB sticks are a problem for these units, 95% of the time the music cuts in and out when played from a USB stick, its weird, doesnt seem to be a power issue either.

Anyone using video output?

Hi,

First off, thank you to all of you guys for the great information posted here. I just wrapped up my install of a KLD unit from Pumpkin and I think everything is working with exception of the followings so I am hoping someone else might have some experience with it. I've searched the post but couldn't find anything yet.

1. My unit has a 30 pin IPOD connector, when I have an IPOD connected to it, the IPOD screen will show "Accessory Connected" BUT on the HU, it's showing me my IPOD is connected but does not show any songs and I can not start/stop any music. I've check the settings menu and it does have an IPOD as installed in the option.

2. I've connected the video output of the HU to my headrest monitors and the pictures on both are in black and white. I've tried both video out1 and video out2 as well as different RCA cable.

I am running MCU version 2.3 and coudu's KitKat 4.4.4.

Any thoughts?

Thanks

The video problem sounds like its a PAL/NTSC issue.
[MTCB Android Head Units Q&A] mbarijfh:
Hello,

short feedback on this; I tried it today; took a bit, since I first had to update the system, I still had the original unrooted firmare+android on it.

With the skript I didn't succeed, something was mounted, but the paths were not correct. I also tried to set a symbolic link with ln -s, also that didn't work.

What worked at the end was following your suggestion with foldermount: first I installed a small map on the internal sd, moved it then with FolderMount to the external sd, and now there is enough space for the large map, fine... - I just have to sort out how that works with the install-recovery.sh and the lsd command (..that doesn't work on terminal right...) in order te get rid of foldermount again....

Best regards,

Michael
[MTCB Android Head Units Q&A] cuboy29:
ahh.. sound like that could be the issue but I don't see any option to change from PAL to NTSC. I've attached another video source to my headrest monitor to verify that the monitor does indeed work properly so the issue is from the HU. Checking with Pumpkin now to see if he'll respond.

thanks.

conclusion: max capaticity for that JVC unit is 320GB. might be differend for your unit. try a smaller harddrive.

WLAN Modification

Hi, for everyone who is interested in

The WLAN reception in my unit was that much poor that I decided to put another Antenna. The original is just a shielded wire where at the end the shield is removed. But the worst thing is that they just taped this wire on the inside of the metal HU box.

So I soldered an old antenna of a AVM Fritzbox WLAN Router on the board and mounted this antenna outside on the HU. The result is not tremendous but now WLAN reception is much more stable. (up to 150Mbps WLAN AP is in my House, the car about 10m away on the street)

I added 3 pictures of the modification just for those who are interested.

Please bare in mind that doing that mod will definately harm your warranty and can damage your HU!
[MTCB Android Head Units Q&A] wokro:
internal / external MIC separation - Modification Variant

Looking to improve my BT MIC quality I found several threads for modding the HU in this forum. So I did also the separation of the internal and the external Mic by removing C32 of my Klyde unit.

But I tried to keep my external cabling of the external MIC and decided to just cut a wire on the PCB in front of the USB 1&"2/MIC connector on the back side of the PCB. I solderd a shielded MIC cable from the the connector to the BT module pins and removed C32 to separate the internal MIC and the external. Now the internal is used for Android and the external for BT Hands Free. The result is as described in many threads before. Still some friends tell me that the BT Volume of the MIC is low. I will try to get another, better MIC as well.

So for everyone interested in my way of the Mod, please find some pictures attached. Please make sure by a Multimeter that you cut the correct wire before cutting any wire on the PCB or removing C32. As mentioned in other threads already: The int. Mic and the Connector Pin in the back and the C32 condensator pin are wired directly and you should have 0 Ohms between these 3 points! Removing C32 will separate the BT module from this connection. Cutting the PCB wire (as I did) separates the backside MIC Connector from the Android MIC input!

Please bare in mind that this mod definately harms your warranty and may damage your device!

Actually it hasnt been mentioned before, what has been mentioned is a very similar issue with music but only with USB sticks, HDDs and SD cards work fine.

---------- Post added at 11:14 AM ---------- Previous post was at 11:12 AM ----------

There is a similar problem with music on USB sticks, but HDDs and SD cards work fine, interesting the video version of the problem is ok with USB sticks but not with HDDs. I guess it could be a power problem, my HU plays music and videos fine from my 320Gb HDD, this HDD has a "y" usb cable and it will only play from it if the extra power usb plug is plugged in to another source other than the HU (doesnt work if the extra usb is plugged into one of the other usb sockets on the hu). Take it your HDD is a low power one with just a single usb plug ? You could try a power usb hub, using one DOES NOT sort the usb stick problem with music, but it may possibly sort your problem out, or you could get a "y" usb cable and plug the extra usb plug into another power source.

Yes, a few days ago some on here bought one (check out posts for pics etc), his was the 8Gb RAM model, glad there is a 16Gb version, hopefully 2Gb RAM also, that link is titled "RK3066" though and the quad cores are RK3188, also date is 2nd Feb The quadcore unit are supposed to use the same firmware as the dual cores, I guess the 16Gb units will use repartitioned version cos of the extra size.
