Please help me identifying this MTCB - MTCB Android Head Units Q&A

I've got this MTCB: MTCB-YZ-V2.81
I though it was by Roadmaster and contacted them but they claim it's not their unit.... how do I know which MCU can I use with it?

If your not having issues with the headunit I would not try updating the MCU, it does not add many new features and can sometimes cause new issues. Are you trying to install a custom ROM?
Where did you by your headunit from? Was there no identification on the box? I never seen a MTCB MCU with XY.

The box just said Himax...
I am not trying to do a custom ROM. Mainly just playing around. The only issue I realy have with it is that it does not show RDS station names...

If you go to Settings-factory settings there should be some option to enable it.

I came across a thread yesterday that it may or may not work on certain devices due to certain radio hardware.

[Q] BlackJelly help - FM Radio

Hi
I would have put this under the BlackJelly thread in the dev forum, but it seems that I'm not yet allowed to post replied there. So, I'm posting here, in hopes for help.
I have a few issues, but I will open them up in seperate threads, as though they are all about basic issues w\ BlackJelly, they are still quite distinct.
I'll start off by saying that generally speaking, I LOVE this ROM. I do, however, have a few issues that I need to take care of.
One of those issues is the FM tuner. It doesn't seem to exist. Is there any way of adding this functionality. Something to flash or an apk or something?
Thanks!

There are quite a few internet radio apps (like pandora) but I'm not sure about FM radio specifically.
Thanks for your input, but I didn't mean internet radio. I meant using the device's fm radio. As in not via internet.
anyone else got an idea?

Sadly North American models did not get the FM radio hardware. It's not possible... sorry
Put all your questions here to keep it cleaner or post in the "stupid Questions" thread and we can help there
Really???
That is so strange and such a shame.
Thanks for the help!

Apparently, losing FM capability was the trade off for getting LTE.
International version of the S3 has it the other way around.
Hmm... That's a bummer. Especially seeing as I have no idea if LTE actually works in my country. Is there any way of knowing if I'm using LTE or not? (Other than asking the cell-phone company reps, who are completely unaware of what LTE even means)

[Q] Phone call audio switches back to handset from bluetooth

I've had bluetooth headsets forever and this problem is killing me!
Currently running CleanRom AT&T SE3.0 but also had the problem with his 4.9 international version, using I317UCAMA4 for the radio. Headset is Jawbone ERA.
What started happening recently is that I'll answer/make a call on the headset and randomly it'll switch audio back to the phone, either . I'll suddenly realize it's happened and look at the dialer which shows that it's still going to bluetooth. I can listen to bluetooth audio streaming and it never happens, only on phone calls.

I had this issue b4, but changed Bluetooth earpieces already!! Using Q3 and the Plantronics Legend...
But I'm thinking you may have to delete the Bluetooth paired link. And try re- pairing it too the phone again.. it helped me once!!

Found out that it seems to be a common problem with Jawbone...a software update at some point may have been the culprit or not, either way, no resolution.

Yeah, there's only one update and most people are claiming that's what started a multitude of problems. I already updated a long time ago.
On the other hand, I tested with a older Blueant Z9i I had laying around and discovered the same problem which points it back to the ROM or radio, I'm not sure which. I'm currently running CleanROM ATT SE3.0 and UCAMA4 for the radio. UCAMA4 is the most current radio right? It was happening on CleanROM 4.9 and the previous radio as well though so I'm pretty confused.

Here's the latest MODEM UCAMC3:

That might help your problem!!
Don't think it's Rom related tho. If you want to try something similar to clean Rom with a few added features, look here. Same thing I'm running NOW!! Skynote 9

[Q] Phone call audio problems

Ok, so I thought initially that it had to do with my bluetooth headset and the audio switching away back to the handset randomly (headset icon in the dialer stays lit). However, I also noticed now that when I'm sitting at my desk and it switches away from the headset and I then press the speaker icon, it'll also suddenly turn off the speaker as well and go back to the handset.
Running CleanRom AT&T SE3.0, I317UCAMC3. It's followed thru on a couple different rom flashes and modems so I'm not sure what the problem is, maybe radio related? RIL?
Not radio or Ril....
More likely a blue tooth reception issue. .
Look into the Cleanrom thread for the blue tooth related issues it had..
I haven't used CR for a while. ..so I can't remember the particulars. ...g
Edit...
Can't find the 3.0 link. ..and would like to review it again. ..
Have you got a working link ?

Yeah, but it's not just my bluetooth, it's even when I'm on speakerphone it's switching to internal again. Happens to two different bluetooth headsets as well.
But also, doesn't the Radio control the BT and Wifi? Maybe the RIL isn't involved but I thought the Radio was.
I checked the dev's website and it seems that he's retired that ROM entirely as it's no longer available for download. I wonder if he just pulled it due to needing more space on his server, there wasn't any bugs to speak of.

It is possible that your radio could be suffering from a problem. ..
The best way to test would of course be a complete restore via Odin. ..using Mr. Robinson rooted build. .then running triangle away and so forth. ..
It would tell you your radio condition....and if you are having trouble stock...then the device may be damaged. .
And regarding the 3.0 rom...I believe it's gone as well. ..g

4.1.2 bluetooth MAP on 4.3?

So, I updated to 4.3 and now my focus is having problems with bluetooth. It used to work perfectly before the update but now the metadata of the song doesn't update on the radio and some other things like texts don't come through like they used to.
Simply put, is there a way to get the old bluetooth "stuff" into 4.3 or is that baked in?
I was just studying the BT issues and I found out all phones with 4.2 or greater has BT problems across the board.
Can you just copy-paste BT files? I don't know.
But its a common issue.

That's what I aim to find out... I'm tempted to just go back to a 4.1.2 ROM but meh...
No, I agree about staying with 4.3. I'm sure Google will release a fix or a clever xda member will get it.
Bump, still looking for info :laugh:

Can you explain what are the exact problems you experiencing with BT.
Because I'm not getting any atm! Just curious is to what's not working and what is...

Sounds like he isn't getting song info and text messages on his car's head unit when connected to the phone through BT on a 4.3 ROM.
Me, I just get choppy playback.

Pretty much. I used to be able to see what was playing. I used to be able to control pandora (pause/skip) but that no longer works either. I also do not get notifications like texts anymore.

Quoting you too so you get a notification,
Edit: quote from a verizon thread:
Just so everyone is aware, this is due to the whole Motorola/Google ownership change. In previous versions of Android, Motorola sourced their own protocols for their products, and included MAP in their bluetooth profiles. Since the Jelly Bean update, they've used Google's own Bluetooth protocols, in which MAP was omitted.
is this true? Surely not, how would it have worked on 4.1.2?
Edit again:

Says kitkat supports MAP again............. may just get a kitkat rom even though I'd rather stick to stock TW.....
Well, I updated to 4.4 ........... still no go

Bluetooth keyboard compatability

Hey so how many people have the Bluetooth keyboard/Bluetooth mouse problem where the connection cuts off after a few seconds and you cannot type? Is this indicative of a bad unit or is it a problem with the firmware and an update should fix it? Tried logitech, some China brand and another off amazon. None work continuously. It just disconnects and then if you type something it connects soon after..so frustrating cause I need a keyboard

When the N10.1-14 first came out there were reports of the same issue you're describing. It seemed to have quieted down. It is a h/w issue because people who exchanged their devices and got new ones no longer had problems using the same previously problematic HID devices including the Logitech K810. I'm a pretty heavy BT user and (knock on wood) have never had an issue.
Yea I contacted Samsung for repair. Hopefully it will fix..I really don't want to go back to the iPad due to iOS..everything about this tablet Is so nice

Hope they can fix it for you. I use a Logitech K810 BT keyboard and a Jawbone Jambox BT speaker w/ my GN/2014. Never had a problem with either one disconnecting. Just in case Samsung doesn't fix it (they don't have the best track record), can you exchange it for another one?
Nope unfortunately I bought it back in January so I gotta get it fixed or I gotta sell it lol.

But seems like a lot are having luck with the Logitech 810.. May give that a try
Sent from my SGH-I337 using xda premium
I had the same problem with the k810 tried other keyboards as well. I also believe it probably is a h/w issue. I rooted mine am running Scotts rom-clean rom 2.0 r2. I installed a root enabled app called Bluetooth keyboard easy connect by Mike Van Den Sluis, and also found another root enabled app called Bluetooth keyboard bug fix by Felipe Porge. I also don't have Samsung keyboard installed I'm using Google keyboard. With those changes I have fixed the problem and am no longer having any problems, I'm not convinced that the bug fix app actually did anything but in following the instructions for the BT keyboard easy connect and also granting superuser permission the problem is solved. My only problem is with clean ROM none of my air commands are working, not sure if it's due to something I did or if they are just not enabled with clean ROM.
Guys,
It seems a software-solution might've been found. Check the BT Keyboard thread (14 pages long). (I do not know if re-posting is allowed or not...)
