MDU Canbus change

Hi Guys

is there any way to change what appears on the MDU of a mazda 6 or any other car that has an MDU?

currently when not using radio or anything it will Show Other

also on radio it shows the Frequency and MHZ, could the RDS not be displayed there instead?

Dan

I was really impressed with the build quality (check out all those tantalum caps), then I saw the antenna. Thats going to be the first thing replaced in mine. Only three electrolytic caps visible. Would be nice to replace them with some polymer organic caps.
[MTCB Android Head Units Q&A] typos1:
It depends, its not supported on all cars, I would try all Mazda settings in factory settings/CAN Bus and if none work try all the CAN Bus types, if nothing shows on your display in with any of the settings in CAN Bus then it aint supported, it may be in future, though theres no guarantee. What unit have you got ? - You could try asking the manufacturer if they could enable it.
[MTCB Android Head Units Q&A] dannyw13:
I mean the screen does work if I goto music it will show music on the screen if I goto video it will show DVD on there but when on radio it shows the frequency for instance 95.8 MHZ I would prefer it say the radio station name do you get what I mean . who would I email? I have a klyde unit
[MTCB Android Head Units Q&A] typos1:
Sorry, I only answered your first question in my last post.

For the second, I assume youre talking about the widget on the homescreen and I agree its stupid to have RDS displaying the station name and the widget only the frequency, two options here, either email Klyde and ask (someone posted a list of contacts there on or two pages ago, Linda is nice) or try and decompile the launcher apk and slightly alter the built in widget to display station name.
[MTCB Android Head Units Q&A] CHUNKYBOWSER:
Hey everyone,

I'm using Poweramp as my music player and I was wondering if it was possible to have the radio automatically mute as I open up Poweramp, without specifically exiting the radio app. I've tried Tasker but it doesn't seem to work with the Radio app. I've searched through this thread but I haven't found much mentioned in regards to this.

Thanks.
[MTCB Android Head Units Q&A] agentdr8:
The solution I came up with to handle this situation is with alternate launchers for Radio and Poweramp (or your media player of choice). These alternate launchers are included with XposedMTC. They're basically wrappers for the stock apps, but control the audio output streams so you don't get overlapping sound.

At some point in the future, if I have some free time I plan on writing a service that can monitor both the foreground app and audio outputs, and (hopefully) intelligently switch between them. That would replace the alternate launchers and the mode switching in XMTC.
[MTCB Android Head Units Q&A] geezi:
Could you please care to explain in more detail.. I tried following [MENTION=6041319]dsa8310[/MENTION] instructions as well but just get confused.

Can anyone just make a step by step with pics to explain. I will greatly appreciate it.

Thanks
[MTCB Android Head Units Q&A] manicuspanicus:
In my case, with what you made/ gave me, the unit behaves exactly the same on every boot and super fast I should add. I'm not changing my rom even with money!:D
[MTCB Android Head Units Q&A] dark alex:
If that device is relying on microntek, too - YES!

The problem is that I have to tell a part of the system to change volume.

By deafult this is done via Android API (AudioManager.adjustStreamVolume(...)) but on our unit the MCU deals with most of the sound setting. So it does with volume control.

That's why I had to talk to the MCU to adjust volume levels. I don't linke it but had no other chance.

Feel free to link to my posts if you feel it fits the thread. I will not for now as I do't really know.

I am currently thinking about asking XDA's staff to create a section for Car Headunits in general to have things a bit more sorted...

Then I wold create a Thread (or multiple)

Btw: If the App is not compatible and you can fiind out how to control volume programmatically I can patch my app!

Probably volume is not MCU-Controlled there? But that's offtopic. Please PN me for further discussions on that.
[MTCB Android Head Units Q&A] R4D3N:
Thank you for your answer.

So Erisin is actually a supplier for HuiFei units?
[MTCB Android Head Units Q&A] agentdr8:
Yep. Although when I contacted Ivy at Erisin, she was unaware of the KGL part numbering. I couldn't get the KGL-7610N from her, so I found another supplier on AliExpress. Hanker Yu told me "if it has our interface, it is a Hui Fei unit". Not really confidence-inspiring, considering all the knock-offs and supplier-modified units (such as those from Green Point).
[MTCB Android Head Units Q&A] R4D3N:
On their website it has another name, but is it the same unit?
[MTCB Android Head Units Q&A] agentdr8:
Looks like it, and the specs seem to indicate it is.
[MTCB Android Head Units Q&A] typos1:
It might be that Android still talks to the MCU in the same language ?

Or that it would need a relatively small mod to make it work.
[MTCB Android Head Units Q&A] R4D3N:
If you look in the Pictures from the settings on their website, on the third row to the right is the Amplifier Setting screen and it has a LOUD option which can be activated. That means that they modified the settings to have that option or it's a different unit?

Anyway, I'm 99.9% decided to buy the unit from Erisin and I will post a review for the unit.
[MTCB Android Head Units Q&A] dark alex:
currently I cann a API aof the MCU. If the other unit also has this API in a similar way its easy.
[MTCB Android Head Units Q&A] typos1:
You mean "Loundness" ? think they all have that.
[MTCB Android Head Units Q&A] R4D3N:
Yes, I mean Loudness.

But, if they all have that why in the previous pages they made an app which automatically sets the LOUD active?

If they all have, what does this do?
[MTCB Android Head Units Q&A] agentdr8:
It's a setting that isn't persistent across restarts, so there are ways to work around it if you want Loudness always on.

Amp?

I got the following wiring diagram and screen shot from one of the sellers. It appears there is only wiring for a subwoofer but no amp control. Specifically my F-150 audiophile system (see attached) has pinouts for "Subwoofer amplifier - Enable" and "Shield" but I don;t see anything coming off the radio that would hook up to this.

Does this mean that external amps do not connect to this unit? The AN 21U units have it, although the one I have sounds like crap. Has anyone connected this to an external amp? Am I missing something?

[MTCB Android Head Units Q&A] RaZi3L_:
swc dont work

hi

I need your tech acknowledgment and support because I think the seller of my HU is trying to lie me.

I have a Hyundai ix35 and a month ago I buyed this HU: http://es.aliexpress.com/item/1024-...1-2012-2013-Car-dvd-gps-with/32280518971.html

The HU is perfect and works great... except the steering wheel controls. At first the seller say me that this unit is plug & play, there is nothing to do except to connect cables from my car into his cable interface as you can see in attached photo. But when I try to reprogram the buttons with the proper application, nothing happens (as you can see in this video: https://www.youtube.com/watch?v=P__PQ9dpTw0 )

My car has not canbus so my swc is resistive. I tested my two swc cables with a multimeter and the resistance and voltages are correct (I have the electric handbook from my car with tables with voltage and resistance values for each button from swc) so the problem is not on my side, is on the HU. I don't know if it is an electrical or software problem, but is on the HU.

I've told all this to the seller and his new answer is now as follows (literally, so if my english is not so good... his english is worse):

I have not enough technical knowledge to do electronic modifications or replace the motherboard, but I seriously doubt that what the seller is telling me is true.

I asked the seller to send me the video with the instructions to see exactly what he proposed, but it sounds very strange to me.... As far as I know all HU SWC interfaces are resistive. And, when a car has canbus, you need a canbus decoder to translate 0/1 values to resistive values so the SWC interfaz from HU can understand it.

Or am I wrong and what the seller tells me can be true?

Is there anything I can do to try to solve this problem without getting a soldering iron?

PS: just if you are curious here is the video with the test of my swc cables with multimeter https://www.youtube.com/watch?v=BBCTfdr3dEk

[MTCB Android Head Units Q&A] javlada:
I'm wondering why the Radio won't switch to standby mode when you turn off keys. If you have a phone with 2000mAh battery, it is able to stay in stand by for a whole week.

The behavior I would love to see would be like this:

If I turn off keys the radio would ask me if I want to switch to stand by. It would automatically switch to it if I won't answer within 5 seconds.

I could turn on the radio from stand by even if car keys are off.

The radio would automatically switch from stand by to completely off after 5 days or whenever the battery voltage goes below a limit.

Is this so hard to do for the manufacturers? Can a behavior like this be reached somehow on the current units?

I asked the question on a Honda Prelude forum and looked in the workshop manual which has wiring diagrams.

[MTCB Android Head Units Q&A] agentdr8:
Yes, I agree that's how it should work, but the mfg(s) of these units didn't consider it necessary. It's possible that they believed a dead car battery is worse than a dead phone battery; one leaves you stranded waiting for a jump/tow, the other is just a minor nuisance (aside from emergency situations where you

really

need a phone). Either way, there's no way to fix it without modifying the MCU code (along with the Android code), and since no one here has the ability to do so, we're left coming up with our own solutions to the problem.

Even if we can get around the MCU shutting off the power to the board/amp after the ~30sec shutdown, the amp would still draw power, and run your battery flat over the course of a few hours. You have to consider that most all Android phones/tablets don't have the additional power-sucking hardware that these types of devices have.

External Wifi Dongle

Hi all,

I accidentally broke my KGL internal WIFI card, so it not work anymore.

Does anyone had any try using external WIFI? I tried it with 2 WIFI dongle but it didn't work.

One dongle from Prolink that I forget its chipset, and 1 more unbranded with RTL8188ETV chipset (as shown in Windows PC).

I look into my KGL board, and on WIFI module I saw RTL8188CTV written in the min IC. Is this the problem?

Should I instal the driver that suitable with my External WIFI dongle?

As far as I know you are right about all units being resistive SWC and the CAN Bus box converting the signals to CAN Bus signals, have you used the thread search box to the right ? I have heard of similar problems before but I do not remember the exact solutions. Of course you could always use buyer protection and said it back as not working if you cannot find a solution.

If you read the threads (AN21-U, Newsmy NU3001, Ownice, this one) theyre all a bit buggy, but most can be sorted.

These units are the most popular, thats why the thread is so long.

Blame the XDA mods for the length of the threads, they consistently refuse to allow a specific head unit forum and all requests for device forums so each device can have sub forums are totally ignored, not even a "sorry but no".
