Music App Issues

Hi guys having an issue with the OEM Music player on my Head Unit (MTCD_HA_v1.53_1). I listen to a lot of DJ Sets which are one track and in excess of 30 minutes. When ever I try to access one of these tracks from my USB stick I get the message "Unfortunately Music has stopped." However my short single track music plays with no issues whatsoever.

I have tried clearing the cache, data etc with no success in getting this to play.

Details:

MCU Version: MTCD_HA_v1.53_1

Android Version: 5.1.1

Kernel Version: 3.0.101+

root@chun #43

Build Number: rk3188-userdebug 04052016.09:53:00

Any help to get this to work would be much appreciated. Also who is the manufacturer?

In Google Chrome u see what is going on.

Downstairs in the bar you can see the progress. but it takes quite long.
[MTCD  Android Head Units Q&A] Rausiman:
Has anyone tested the new firmware?

And this is really the latest for LM of Erisin?

If Yes, which version is it.
[MTCD  Android Head Units Q&A] Musicman1973:
I have tested it !

Yes it is for the LM from Erisin.

The DMCU is LM 1.82b_1 and the Software is from 16.08.2016 !

[MTCD  Android Head Units Q&A] DanB0y:
You can use the dupdate.img on any MTCD, just dont copy the dmcu file with it if your MTCD is not a JY type.. I feel like repeating myself lol

The dupdate file (containing system files, updated kernel, etc) is what brings performance enhancement, not the dmcu.

Ah i thought it is a Hardware Driver optimisation in mcu which did the speed up. That both are seperated is clear.

Does anyone know how to use any other app while using the bluetooth to talk on the phone? It's not ideal that you can't look at the navigation (waze) while you're on a phone call.

Hi Marius.

I have a very similar unit but from Xtrons. I am very happy with it so far.

I see on your pics that you have shortcuts under the clock on the home screen. Mine has the music player if it is open or the weather if not.

I would like to put a Poweramp widget there, but I can't find a way to change it. Do you have any ideas?

Thanks :)
[MTCD  Android Head Units Q&A] Luxferro:
Does anyone have working canbus with these newer units?

Some of the steering wheel buttons on my car function correctly, while others do nothing. And the steering wheel app doesn't do anything, nor show any buttons. Xtrons suggested I refund it, saying they can't test it on every car, and that it is likely software/firmware issue.. But I don't really want to return it, as I'd like to get it fixed/working correctly.

Here's a short video showing that some of the buttons work, but the steering wheel app does nothing: https://goo.gl/photos/pPizeQ4We2UyqwoLA

edit: if someone can resolve my issue, I'll send then $20 via paypal :)

[MTCD  Android Head Units Q&A] Marius B:
Put no on can model and maybe work. I think is some error in apps.

Send by phone
[MTCD  Android Head Units Q&A] doctorman:
if some SW buttons work and not others that means there is something wrong with your canbus or the settings of it.

you should contact your seller for the correct setting or possible canbus software/hardware update.

I know Joying updates the canbus once a while for different models.
[MTCD  Android Head Units Q&A] hadeone:
Did you go into FACTORY SETTINGS and try the different CANBUS settings in there?
[MTCD  Android Head Units Q&A] Luxferro:
Yeah, I have contacted them. But they said they can't test on every car (Even though this was specifically made for Audi TT), and suggested I return for refund.

The main issue is that the software (steering wheel settings app), does nothing. If some buttons work, it means the canbus adapter is working.... but shouldn't that mean the software should at least be talking to it and allowing me to map/re-map buttons?

I'd just like to see anyone with MTCD, showing the steering wheel app working. Maybe the app doesn't work? All videos/pictures I've found are for MTCB steering wheel settings, which I'm told is totally different in how it behaves.

---------- Post added at 11:42 AM ---------- Previous post was at 11:42 AM ----------

Not yet, but that was the next thing I was going to try - my downpipe (exhaust disconnected from my turbo - bad install job), so I haven't had a chance to mess with the radio more. I have gone in their in the past, and I believe it was set to an Audi A3... there was no Audi TT listed. I plan to just try all different ones soon as I get a chance.

edit: also, there is really one set of buttons that do nothing. the left scroll wheel on my steering wheel. Normally it would be forward/back for tracks, ect. Maybe it only works in specific apps? Either way, I'd like the ability to re-map buttons.
[MTCD  Android Head Units Q&A] Marius B:
My friend go to factory setting and in can select no and check if work and then tell me .

I have the MTCD unit in my E46 BMW and the steering wheel app does nothing. All my steering wheel buttons work and are mapped to Volume, Radio Tuning, Bluetooth calls, and cycling through the music/video apps, BUT they only work when NONE is selected under CANBUS in FACTORY SETTINGS. That's the case with my car, your's might be different but I would try playing with the CANBUS FACTORY SETTINGS. Good luck.

Anyone know how to get the UP/DOWN buttons that change the radio stations, to change tracks in PowerAMP or Spotify? Right now those buttons only work with the radio app and nothing else.
[MTCD  Android Head Units Q&A] Pattond:
About to pull the trigger on the Erisin for my E46. Any issues I should be aware of?
[MTCD  Android Head Units Q&A] conspiredminds:
First and foremost, pardon my ignorance.

I believe that we have the same head unit. I purchased it a week ago and i have a few questions that might set me off in the right direction.

1. The radio reception sucks. -- I see posts about purchasing an antenna amplifier (cant post ebay link since i'm new to forum search "New Black Car Truck Antenna Radio FM Signal Amp Amplifier Booster" ) and posts about soldering/re-soldering the antenna wire internally. Any guidance on this? has anyone been faced with the same issue? How did you solve it?

2. The weather app bug. -- The weather app does not update. This seems to be a common issue and fixing this issue requires modifying/updating the firmware.

3. Factory Backup -- Is there a correct way to back up the unit? I see that there are different versions and I would just like to ensure that i'm doing it the right way for my version (D, i think). Once i have a backup to fall back on i'd be much more comfortable poking around/modding the device.

4. Updating -- The update process seems pretty straight forward. Can someone provide a link for the updates for this version?

5. What is the MCU Version? I understand that we have the D version and that others are not compatible. What is the most up do date ver for the D?

6. Android Version - Android 6.0+ is available for other android devices. From what i understand, 5.1.1 is the most recent for our head units.. is this assumption correct?

7. Kernel Version: 3.0.101+, is this good here? Possible to update?

My device: ("imgur.com/0ntBBck" apparently i cant post image links either since i'm new...)

As i mentioned before.. pardon my ignorance, i'm brand new to this platform and i'm trying to get the basics down before i begin tweaking. Hopefully i'll be able to contribute something in the near future.
[MTCD  Android Head Units Q&A] Luxferro:
Thanks, that just confirms my suspicions. That the software (steering wheel app) is broken.

I don't think any of these retailers actually has hands on experience with their products or developing them. They just rely on the "factory", AKA as the OEM that actually makes the hardware, and add their branding. So I guess we just have to wait for the software to mature, or a dev here to get their hands on one and fix the issues they left behind.

[MTCD  Android Head Units Q&A] hadeone:
Same issues as earlier models. Terrible internal mic. I installed the external mic and now people can hear me on bluetooth calls. Some static on radio stations that wasn't there with the stock radio. I think overall sound quality has gone down but haven't put too much time into adjusting equalizer settings. I have some fitment issues in my car. The back of the unit hits the air ducts on the left side. Can't fit anything into the USB plugs or else the unit really doesn't fit. The other guy who has this unit said he didn't have this problem.

Glare is pretty bad on this screen. If the sun is shining on the screen you can't see anything. Lowest brightness setting is too bright for dark areas at night and highest setting isn't bright enough on sunny days.

I consider these small issues annoying but overall I like my unit. Lots of functionality for the price you pay and the kinks can be worked out if you have the patience and with the help of the devs on these forums.

---------- Post added at 04:31 PM ---------- Previous post was at 04:24 PM ----------

@conspiredminds some antennas are powered by the radio so you need to connect the blue? wire on one of the hu harnesses to your antenna. You may need another harness/converter for the antenna wire to do this. I'm not sure but I've seen this issue pop up before on other forums. Some people can't tune in to stations. I don't have a problem tuning into radio stations but I do have some static that wasn't there before.

As for updating, you have to be absolutely sure you get the right software for your unit based on the MCU, Kernel etc. found under Settings. Marius B posted an update for the 3062 E46 unit but I haven't tried flashing it yet since I'm not sure what it is suppose to do/update.

Blank Wheelkey app

I also have this problem on a Peugeot 407 head unit. The volume worked by default but when I open the wheelkey app I get a blank screen.

Most of my other CANBUS works properly e.g. air conditioning controls.

Did anyone figure out a solution for this?

My unit is MTCD_MX_V1.81 August 19th 2016.
[MTCD  Android Head Units Q&A] daylankai:
Can I ask, does your 407 have a factory fitted CD Changer?

I also have a peugeot 407 MTCD_MX head unit, and have similair problems. It is very weird to be honest. The volume controls work fine, but other steering wheel controls function strangely. If I press the buttom that brings up my mpg, I can press next/previous track once but then it becomes unresponsive. If I press the MPG buttom again, I can press next/previous track once again. If I go to the steering wheel assign, it does not allow me to change anything. Infact when I do try, the unit pretty much ignores me, with the volume buttons continuing to increase/decrease the volume.

I have even tried a connects2 canbus adapter, but the steering wheel assign still does not work or seem to recognise that any button is being pressed.

The canbus adapter supplied was a PSA-Bagoo-BG-02 407.

In the faxtory settings (126) it is correctly set as PSA Bagoo, and have tried all the other PSA versions and also tried No Canbus, but nothing seems to work.

On a wide note, although the button for MPG brings up the correct screen, it does not display correct information, and is permanently set as KMPG without anyway to change it. Also, if I plug the little LCD screen in, it is constantly displaying an hourglass symbol with the words "waiting for CD"
[MTCD  Android Head Units Q&A] markze:
Peugeot 407 Canbus

Mine was just a stock RD4 with no CD changer.

Sounds like the issue is common for all units until Witson improve their MCU firmware.

I have the same problems with the trip computer. The values are wrong. I still get the correct information in the factory instrument cluster.

One problem though the factory odometer and cruise control setting display has changed from km to miles when I had the battery disconnected and the new head unit and I cannot find a setting to change it back as with the RD4 menu condigurations. I will have to temporarily swap the RD4 back in there to change my odometer back to km.

When I get a change I might start a Peugeot 407 specific thread and list all the bugs I know about.

Good news today though I found out how to reverse the airconditioning controls. My car is RHD so the dual air con temperatures were showing the wrong way around. In the canbus settings there was a air conditioning swap key. I changed it from normal to swap and it reversed the temperature displays.

I have not found a setting to turn off dual climate. With the stock head unit I always had it set to change both simulataneously.

If only I could find a similar setting for the fader. When I use the driver setting in the fader it moves the settings the wrong way so I have to settle for a custom setting which is ok.
