I finally got CarAudioService working with my SWC buttons. With v1.3, the SWC buttons were recognized and even displayed Toast messages ("Previous Track", "Next Track", etc) but didn't do anything. I tried v1.2 and it works perfect! So if anyone is having trouble, try the older version.

My only complaint is in the radio app the SWC buttons still tune up and down instead of switching between favorites, as with the face plate buttons.

On

Attenuation -9

Attenuation -10

Off

I have it currently set to Attenuation -9 so I can hear my parking sensors, but attenuation -9 is almost as if the music is off.

Ok, so the problem with the button illumination was a software one. I flashed v1.99 + MTCB-KGL1-V1.99 and illumination is ON baby! :) All steering wheel buttons work, even the call initiation. Although it only launches BT menu, still better than nothing at all.

Push volume key on the unit used to be a back button but I guess I'll have to use the one on the screen from now on. No biggie.

So far no problems with BT or Wi-Fi.

After unit re-starts buttons don't work on poweramp until I have switched to another source (AVin) and then back to poweramp again. Not only is this a bit of a hassle but it also knocks out the rear speakers in my car, so at the moment I am living with skipping tracks etc. from the touch screen.

Radio signal

I just installed one of these(sort of) and have 2 main issues. First, and most important is it has no place to actually mount it to my mazda 6, even though they said it is an exact swap plug and play. Second is that i get absolutely no radio signal. Maybe a spec, but nothing you can make out. Does anyone know why??
[MTCB Android Head Units Q&A] Stank0:
My guess is that you don't have the antenna connected properly. I didn't bother with an antenna and obviously I can't tune any stations but I absolutely don't care about the radio. Good luck.

After you flash it, don't forget to go to the "Factory Settings" and turn on the RGB LED (or something like that. It's a checkmark just beside RDS. Only then the "Element" (where you change the illumination color) will appear.

And you can also change your boot logo if you like. The password is 126.

No AM radio reception

I have a Hui Fei unit that in general works wonderfully (this unit pre-wired for a suzuki SX4).

But we took a drive yesterday and it was the first time I tried to listen to AM radio.

There was no AM radio reception at all -- couldn't tune in a single channel.

The hui fei unit does have a place to plug in the car antenna in the back, and i did plug in my car antenna into it.

Any thoughts on what could be the problem/fix?

------

ps. At some point I posted a photo of some mystery connectors on my HuiFei and someone cryptically suggested that I needed to splice into some wires for something that might be a radio antenna booster, but I cannot find that reply anymore and it didn't make complete sense..

Here is that post about connecting antenna booster that I didn't quite understand but seems intriguing:

I did set my "radio band region" to America in the factory settings area, so I have done that part. But I have not messed with any setting about the radio "chip", which has two choices "TEF6606/TEF6624" (current setting) and "TDA7706". I suppose I could try TDA7706 if you think that might help..

I assumed it was any app that was launching on the BOOT_COMPLETED intent, as I don't have GALA installed, just Poweramp Toast and Car Service and I too was seeing the SystemUI crash.

Maybe the 1.99 image fixes it without needing any delays in app startups?
[MTCB Android Head Units Q&A] Skitals:
I was getting the system UI crash even after uninstalling GALA. I believe the other theory is it's OBD service that causes it.

Well see, that's the confusing part.. I understand that that male plug is a kind of antenna plug, BUT my car has a male antenna wire/plug that was input into the original radio, and it was THAT antenna plug that i plugged into the Hui Fei unit, into the female antenna plug receptacle in the corner of the head unit.

This additional male antenna connector shown in the photo.. if i connected it to the HuiFei, then I would basically be connecting the Hui Fei "to itself". Maybe that makes sense in some scenario where something else gets plugged into that gray connector (maybe that is used in some scenario where a car does not have a standard radio antenna and has some kind of antenna that plugs into the grey connector instead)?

Confusing!

Wiring B+ and ACC (Yellow and Red Wires)

Hi,

i finalized my Porsche 996 Bose Soundsystem replacement. Took out all the MOST-Bus stuff and rewired everything with a new Amp and all 4 ohm Speakers in the car. I managed to connect the Head-Unit to the cars ISO Connector and it is working! Now I have a little question. The yellow wire of the Head Units Iso Connector is connecting to the chamber of the car's ISO Connector which is carrying Battery plus and the red one from the Radio with the flying fuse is connected to the switched ACC+. Since switched ACC+ is coming from a fuse, for what is the flying Fuse? The Radio works either way (it doesn't matter if I connect Yellow to ACC+ and red to Battery+ or the opposite way around). What is right? Any Ideas?

Thanks in Advance

Karl
[MTCB Android Head Units Q&A] agentdr8:
Yellow is supposed to provide +12V constant even when the vehicle is off. Red is for switched 12V, for when the vehicle is in the ACC/ON position.
[MTCB Android Head Units Q&A] dcmouser:
Yes, now I think that makes sense!

But then it seems to me that I've connected it properly. In other words I did not need the adapter so I just plugged in my old standard antenna directly into the head unit. But then the original reply to my question suggesting that i needed to rewire the blue wire to provide power to the antenna booster is confusing..

So the question is -- is my head unit somehow wired to expect me to use this alternative grey antenna adapter, and when i plugged my existing standard radio antenna in, is it underpowering some antenna pre-amp, which is the cause of my non-existent AM reception.. And the original reply to me telling me to splice out the blue wire from the grey connector knew what they were talking about?

Here's an amazon page showing that the gray connector does indeed look like an alternative antenna connector that might be appropriate for some Honda models (I have a suzuki): http://www.amazon.com/Metra-40-HD10-2005-Up-Antenna-Adapter/dp/B000K4YOCG

Does anybody know if there is an bluetooth app which can read out and display the songs from my smartphone (iPhone / OnePlus One) as a list on the device itself? I should also mention that I am using the iPod app and Spotify.

Thanks in advance
[MTCB Android Head Units Q&A] typos1:
AFAIK bluetooth audio can only play mp3s, does not show track info and can only play songs in one folder, its a limitation of bluetooth audio protocol.

Which makes it pants in my opinion, as who wants to listen to mp3s (crappy quality cos compressed) and who wants to stick all their songs in one folder (if youve go 100s you have to press "next" 45 times if you want to listen to track number 45 !!) ?

Better to use your device as a media device and plug it in with usb and get full control plus the ability to play proper, full quality audio files. You also get the added bonus of topping up your charge at th same time.

---------- Post added at 07:38 PM ---------- Previous post was at 07:36 PM ----------

You use the blue wire (which is just a powered 12v wire, same as any car radio) to power whatever antenna amplifier you want, you dont have to get one specific to your vehicle.
[MTCB Android Head Units Q&A] sir sniffalot:
I have Xposed installer 2.6.1 and XposedMTC 1.2.1.

I just tried uninstalling/re-installing but still have the same problem.

I can only gain control of the forward/back hardware buttons for skipping tracks in poweramp by cycling through the MODE button (radio, DVD, AVin) until I get to AVin (selecting AVin app from touch screen doesn't have the same effect). If I then re-select poweramp the hardware buttons work. As I said above on selecting AVin I also lose sound (completely) from the rear speakers. I can get full audio back again by selecting DVD either from DVD button or MODE button. After re-starting or rebooting I have to go through same procedure.

I have a GS unit, MCU version MTCB-GS-V1.85. I don't know if this makes a difference or helps in understanding the problem.
[MTCB Android Head Units Q&A] agentdr8:
Do you also use the Car Service app by [MENTION=5867075]KeiserSozeyFr[/MENTION]? If not, I'd give it a try, as that will enable swc next/prev to work for Poweramp on any source (other than Radio). Otherwise the xposed module only registers a broadcast receiver for the irkeyDown intents when you switch to Music, which is why you're seeing that behavior.

I think I know why switching to AVin is causing your rear speakers to lose sound (incorrect av_channel switching) and will put in a few lines to address that.

At least on my GS unit, the blue ANT wire only gets 12v when the radio is in Radio mode! That's fine for an amplified antenna, but it's not the same as any Acc 12v wire. I learned this the hard way when I tried to wire it to my sub remote turn on line. Took me a second to realize the amp would only turn on in Radio mode. Luckily the canbus adapter had a 12v Acc line I could tap.

---------- Post added at 10:38 PM ---------- Previous post was at 10:18 PM ----------

How do you have the amp connected? MK6 GTI dynaudio amp expects a low-level preamp signal. The factory headunit is programmed for the dynaudio amp to output 4v over the factory harness speaker wires. If you have your huifei headunit attached directly to the harness you are feeding the amp high/speaker-level signal.

Depending on the voltage of the headunit preamps, you either need to cut the speaker wires on the huifei harness and attach RCA connectors and hook them up to the RCA pre-amp outputs (so you are outputting pre-amp levels over the factory harness). The other option is a LOC, which would have to be wired into the speaker wires on the huifei harness to drop the voltage.

I have a MK6 GTI w/o dynaudio, so I would get confirmation on golfmk6.com from someone who has done a headunit upgrade while keeping the dynaudio amp. But that is my understanding, the amp expects a low-level signal from the headunit over the speaker wires.
[MTCB Android Head Units Q&A] dcmouser:
Ok so I think i'm starting to put together the pieces.. summarizing:

1. This HuiFei unit was pre-wired for my vehicle (suzuki sx4), but has 2 ways to connect the antenna -- a standard female radio antenna connector on the head unit itself, and some grey honda style antenna connector that includes a power antenna wire. I use the standard radio antenna connector.

2. The OEM connector coming FROM the car seems to include a wire that expects to receive 12v power that goes to a powered antenna thing somewhere deep in the car.

3. The HuiFei pre-wired connector that shipped with my HuiFei specifically for my vehicle, probably is MISSING the pin for the 12v powered antenna wire. This seems to be the heart of the problem.

4. Because my HuiFei connector is not providing power to the OEM car harness antenna power pin in the car connector, the power is not provided to antenna booster/preamp and so radio reception is bad.

5. The original replier to my question was telling me that i need to add a pin to the pre-wired HuiFei connector to provide power to this pin, and to steal it from the unused alternative radio gray connector.

That's what i now tentatively think.. Though i could be wrong about any of that. Thoughts?

AV-in and Aux In and front 3.5mm connection?
