Satellite radio

Anyone here have an idea if there are any satellite radio tuners available and compatible with this kind of units? :confused:
[MTCB Android Head Units Q&A] uncleg:
Are You kidding ? :) Just imagine sattelite dish on the top of the car :rolleyes:

There is no any sattelite tuners available for HU. Use the external third party tuners and dish systems thru line-in HU connection.
[MTCB Android Head Units Q&A] halloj:
Really, I don't think you ever heard about the US satellite radio, e.g. http://www.siriusxm.com/

You earned this one: :crying:
[MTCB Android Head Units Q&A] uncleg:
Anyway for this service You need a Sirius-proprietary tuner for decoding this signal and flat sattelite antennae. IMHO, just subscribe to their service and listen their radio thru 4G internet via Android APP. Its simpliest way and not need any hardware modifications of HU and Your vehicle
[MTCB Android Head Units Q&A] halloj:
Sure, but what about your ranting about a dish? If someone asks a decent question, why throw sh-t back at the one asking?
[MTCB Android Head Units Q&A] uncleg:
B-cos from Your side, You must ask question in details, which one of the services You plan to use. But You ask a common question without description and got the answer regarding classical sattelite receiving systems.

No sence to be aggrieved. :p
[MTCB Android Head Units Q&A] Ch1337:
Oh... Well that sucks :(

A friend of mine has an almost similar player as me and an iPhone. He has the same issue as me while playing music. When I used my GS6 on his player, it worked great.

My previous player also worked great.

But you're saying that the BT is the problem, so if I - for example - install Spotify on the HU, it should work like normal soundwise? And AUX will not have this problem either?

And will rooting/other software/firmware fix this?

XTREMEMusic APP

Has anyone tried XTREMEMusic APP

http://xdaforums.com/android/softwa...-installer-t3029951/post58824910#post58824910

see if it helps with the audio in our head unit?
[MTCB Android Head Units Q&A] DJCannonball:
That's correct. Aux will sound way much better than Bluetooth on pureandroid hu.

I have several bt devices which sound all great via bt to my livingroom receiver, but none of them sound clear on my hu
[MTCB Android Head Units Q&A] koimr:
I don't think that would explain why [MENTION=7002419]pax83[/MENTION] doesn't have a cold boot the next morning, that sounds more like a "always-hot" wire was connected to the head unit's ACC wire instead of one that only has power when the vehicle is on.
[MTCB Android Head Units Q&A] Sasha0574:
My question was GENERAL, no specfics involved. I am very well aware of Sirius and the likes but not interested in their services. Wouldn't need that for free, let alone pay for it. Also, the question of the "classical" satellite receiving systems involving dishes the size of a garage door could only be implied by sat technology noobs. At home I was using active satellite dish technology until 3 years ago, involving an active dish of some 40x50 cm that did the same thing a 3m diameter passive dish was doing (the automotive "dishes" are actualy no bigger than 5x5x2 cm). Gave that all up for IPTV since I now have a 300mbps internet connection. And my question was abot systems that allow reception of FREE radio channels, obviously 3rd party systems that can be hooked-up to the unit. I did not intend to redesign the unit itself.
[MTCB Android Head Units Q&A] halloj:
I asked nothing. Someone asked a decent question which I understood very well. I also gave an answer

[MTCB Android Head Units Q&A] Resquer:
Good news - the member from 4pda.ru (russian forum) with 7floor nickname has found out how to improve sound control. More info (translated by google from russian): https://translate.google.com/transl...6&view=findpost&p=43606953&edit-text=&act=url

The result is incredible - I never thought that my HU can play music with so great sound quality.
[MTCB Android Head Units Q&A] DJCannonball:
This could be helpful for some, but in my case i just want a clear signal and don't want the HU to add or cut any frequencyranges.

see it as a chain of audio-components, were the HU is the source of the chain.

if the source does add too much lows, then you need an in-line equalizer (or a damn good amp which can do that) to correct the amount of lows in that specific frequencyrange. The same thing goes for too little lows/mids/highs etc.

all i'm saying is: if the HU thru-puts a clear signal in the first place (no messing with frequency cuts or boosts), you don't need any sound enhancements or processing at all.

But i can imagine if you have standard stock speakers (no amps, no extra tweeters/woofers etc) you might get some extra punch out of your speakers from software like XposedMTC

[MTCB Android Head Units Q&A] DJCannonball:
a few years ago i had this exact same issue between a JVC hu and a Samsung GalaxyS3 using A2DP protocol (Stereo streaming via bluetooth)

While my brother's iPhone (iphone 3c i recall) gave a much clearer sound connected via bluetooth to my JVC hu (especially the higher frequencyrange)

it really pissed me off, because my HU was clearly ok.

The devs of XDA looked into this and tackled this problem, i discovered a custom firmware for my S3 called "Cyanogenmod", which had a modded bluetooth-stack from some other device (Nexus i recall)

deleted the old pairing profile and paired my S3 (with CM 9 flashed on it) to my JVC hu and BOOM.. crystal clear audio via bluetooth!

So it can be solved by software, but someone has to implement some other bluetooth stack in the pureandroid's firmware (like Cyanogenmod has), OR correct what's going wrong in the bluetooth connection negotiation

i've read that Android 5.0 will be released soon. i have some hope they will tackle this bluetooth issue from 5.0

The official 5.0 does support USB-DAC which means you can use external USB-soundcards. i hope they will keep that feature in the firmware. like the official android firmware also supports Dail-up-networking (DUN) via bluetooth, but that part is also cut out of current pureandroid's firmware.

for now we are stuck with bad sound via bluetooth and wait for someone to fix it

[MTCB Android Head Units Q&A] Spartoi:
Anyone know how to fix these problems?

1. I was uninstalling some apps and now when I use the ff/rewind buttons on my HU, PowerAmp doesn't change tracks.

2. When I press the play button on my HU, PowerAmp plays, but if I have my phone connected via BT, it will also play audio from my phone.

installed from scratch

Malaysk ROM September 9, 2015 for 1024X600 - RK3188

Xposed installed gave me SD CARD: Null

partition Info:

System 767MB

Data: 0.98GB <- problme

Cache 124MB

SD CARD (FAT) 0.00B <-- problem

GPS SD 7.39GB

Ext SD 2 29.76GB

I installed the ROM 2 times once with clear all setting and once without.. seams like there is a problem with partitioning

my unit is the RK3188 16GB

How can I fix this?

=========

Update:

did the reset as instructed

"After the firmware immediately go to Settings, Restore and Reset-Reset and do reset to the factory and put a tick - to delete all data from the SD card."

partition Info:

System 767MB

Data: 1.98GB <fixed

SD CARD (FAT) 0.00B <-- still zero

---------------

Update 2

wiped the system from recovery

resinstalled with clean setting again

partition Info:

System 767MB

Data: 1.98GB <fixed

I have been searching for an answer to this...

trying to disable the screen saver on the Malaysk ROM but there is no DayDream option to turn off.

please help

------------

UPDATE:

in System/app

MTCScreenClock might have something to do with this

BasicDreams.apk probably is the main one

I have changed it to BasicDreams.apk.old

but perhaps this should be an easy setting to turn off we are just missing it. [MENTION=3590033]Malaysk[/MENTION] please add the daydream option in the settings menu in the next release.

[MTCB Android Head Units Q&A] pwb001:
Thanks very much for the suggestion. Thinking about that, i am not sure it is the answer. If the power to the unit comes from the ACC connection, wouldn't connecting that to a different power source in the car mean it never shuts down? the problem is that it needs to be powered as an accessory, but with the "delay shut down", it is the only ACC still drawing power and makes the vehicle think that it can't enable lock/unlock. Curious to know if the delay shut down affects anyone else, particularly toyota aurion zr6....

In English, "sound effects" sounds almost exactly like "sound defects." :D
[MTCB Android Head Units Q&A] SKOLSC:
Thank's for update Resquer, but i'm not sure to understand, sorry : what's exactly?

A MTC module witch improved sound quality, or a hardware modification on the MCU?

Does we must sold something like on the pictures?
[MTCB Android Head Units Q&A] DJCannonball:
My point exactly! :laugh:
[MTCB Android Head Units Q&A] Resquer:
The main idea is:

The mcu has limited capabilities to manage sound processor, but sound processor can play music perfectly. This modification gives us capability to manage parameters of sound processor directly from android app.

The modification contains both hardware and software modifications.

The hardware part:

- remove two resistors

- solder two wires with resistors 1kOhm (serial connection, you can use removed resistors or others)

The software part:

- add two (or one - it depends from processor type) *.ko libs into file system, change permissions to 644

- install one new xposed module (MTCCSC), activate it, reboot

- install new program for sound ajustment. It will replace embeeded "AMP" app.
[MTCB Android Head Units Q&A] antvic:
Honestly, I don't think that so much effort worthwhile. I think that we forget that listening to music in a car is not the ideal environment.

Currently, with applications such as JetAudio, I think that we have more than enough.

Hello Sasha0574,

great. That was a Problem that i have by the last Update.

That was the reason why i'm kill this ROM and go back to original.

Please,

can you make a Screenshot from this:

Settings, Restore and Reset-Reset and do reset to the factory

and that

wiped the system from recovery

resinstalled with clean setting again

It is not totaly clear what you mean, or where is it.

[MTCB Android Head Units Q&A] 7floor:
The modification takes over the control of sound processor completely - it controls the 3-band equalizer, the loudness, volume, balance etc., - everything that was controlled by MCU, but better, because it allows configuration of every aspect of the sound processor: the gain, frequencies and Q-factor of filters in each of three bands; the hardware loudness module; pre-amplification (as found in factory settings, but now on the fly); the settings of the subwoofer.

It does not change the sound that comes from different hardware modules such as Android board, radio module or DVD player; but it allows to adjust that sound inside the sound processor chip in a more flexible manner, giving you every feature of this chip as designed by the chip manufacturer, not as decided by Chinese engineers :)

And also, these settings (equalizer, preamp, and loudness) are applied on a per-input basis, allowing different adjustments for different inputs (e.g. System vs. Radio vs. DVD, etc. - even for phone conversation)

This is very convenient, as the sound quality differs across inputs and needs to be adjusted differently.

PS. Added a screenshot. It is from Adnroid Emulator because the Head Unit is already in the car on parking. The question mark under Input (top right corner) on real device shows currently active input, such as System, Radio, DVD etc.
[MTCB Android Head Units Q&A] 7floor:
Yes, it requires it. The software consists of two parts:

- an xposed module, to hook two methods in AudioManager class (part of android framework)

- an end-user application, the equalizer.

Reread it. I said change the connection for the BATT/12V/B+ constant power input, I didn't say anything about the IGN/ACC input. The ACC input is only a signal, it uses _very_ little power, and it doesn't draw more power when the unit is on. The power to operate the unit all comes from the 12V constant wire.
