eBay did cancel my auction after I won and told me I could get a refund, but the radio was already in the mail and the seller said it was only "copyright" issues. Perhaps someone didn't approve of that tweaking. But like I said, it seems that the extra '-1' only switched the direction of the knobs.

And yes, bluetooth only works with MCUs with 2501. The way it fails with 6501 is very odd though. On first reboot, it works fine with my custom bluetooth name and password retained. On next reboot, I see 'Android is updating' message and even though my phone says it has connected with the radio, the radio's bluetooth app sees nothing. Also, my custom settings are gone: new name, new password, but again, my phone is already connected with the old name, password, but android doesn't see the connection.

When I revert back to 2501, my custom bluetooth settings are back and android sees the connection again. Perhaps you may be right that there is an alternate bluetooth config that has something to do with OBD.

Hi, it happens to me the same as you, the device is not updated, get the message 'update start followed update off. I just did root and I have not solved, have you done anything else to fix this? . Thanks
[Android Head-Units] MFKinSINY:
You need to pressthe bottom left "on-screen button" first. I believe it says "START". It should then turn "yellow" and change from "start" to "done"

You then press another "on-screen button" that has the function you'd like to control. It should then turn "yellow"

Press the "panel key" you wish to control the function you selected in the second step. The "on-screen button" should turn grey

and populate with the name of the function. You can then hit the bottom left "on-screen button" (done) to finalize if you wish.

If you long press the "on-screen button" you will be presented with additional options for the "panel key" such as "long-press"

example: an "on-screen button" that has the label Menu/Recent will open a menu on single press (primary function) and open recent items on long press (secondary function) IF "long press" was the secondary function that I chose from the list.

Same for the reserved buttons. Just a heads up: The colors & names I mentioned may or may not be accurate as I am going from memory.

"turns yellow" and "turns grey" and changes from "start" to "done" may be represented differently than how I stated. Good luck.

Oh, and IF this does not make your new button assignments stick, you probably have the wrong mcu, I only say this because logically this happens at the hardware level

Are you sure you are looking at the correct thread? Your unit might have a different processor and MST786-based update will never work.

Hi just got the same 3G dongle - it's unlocked and works fine with my laptop (I put it in modem only mode). I can't get it to work in my android car stereo. The signal bars are showing up but no matter what I do the APN details disappear as soon as I save them. I was up til 4am last night trying to get it to work - I tried lots of stuff I found on the net but nothing worked. The only thing I didn't do was downgrade my firmware from 4.1-2.7.11 to .96. Are you still on .96 and if not is your 3G dongle still working? Thanks

Nice, it looks pretty convincing. What is your MCU version string on that board?

If more people can confirm that they have OBD supporting bluetooth, and post their MCU version string, that would be awesome.

I have a unit with inbuilt BT supporting both OBD and phone/music at the same time (simultaniously multi-connect support).

I use it with a cheap BT ELM327OBD dongle on the car-end, works like a charm and autoconnects at startup every time with no problems.

I will post my MCU-string and other info tomorrow (don't have access to my car right now).

---------- Post added at 01:32 AM ---------- Previous post was at 01:27 AM ----------

Just out of curiousity, im on FW 2.7.9 (4.1.1) that came with the unit, and rooted fine and everything works like a charm, by everything I actually mean absolutely everything, everything saves fine, no reset problems with radio, eq or anything, all hundreds of led colors work fine etc.

My question is:

What is better in 4.2.2 based FW other than mirrorlink/widi/miracast that is (supposedly) inbuilt into 4.2.2 on most units, and can I upgrade the FW WITHOUT upgrading the MCU? is the 4.2.2 based fw's REALLY 4.2.2 or are they fake/not real 4.2.2 (2.7.11 - 2.7.26)? Are the 4.2.2 based FW's just as easily rootable? Will root survive a FW upgrade with a root-survival app?

Music player artifacts

Hello all,

I tried upgrading my music player to Rocket Music Player for the album art and search options etc but it would not play nice with my unit. It would come on when it wasn't supposed to or it and the stock app would play at the same time. I tried changing the priority but that was iffy at best (you could tell it was not a happy coexistence), now using the stock music app. I'm ok with that for simplicity BUT I'm getting some artifacts during playback. You know, a digital squawk now and then. Anyone else having playback issues and have you dealt successfully with them?

Not sure of my version # or MCU, but my unit is the one with a single volume on the left with menu, back, and eject button on top of that.

Thanks for the great source of info,

Don

PS - for those who are on the fence buying one of these: it's like anything Android, there is a fiddle factor until you get things the way you want them. Another user said it best: in 5 years everyone will have Android in their car but right now we are on the cutting edge. If you're not prepared to do the tweaking maybe you might be better off with a $1500 Kenwood that has Pandroid or Mandroid or whatever they call it with all the bugs already ironed out.

Problems with the stock Phone app

Hi,

I have a few problems with the stock phone app and I am trying to figure out if anyone else experienced these issues.

(1) The volume is so low when the person calling me talks that I need to increase it up to 8 or even 10. I was used with systems that at least will make the difference between listening to the BT apps vs other apps in order to not go very loud when I listen to the radio...

(2) When somebody calls me in and the stock phone app is not already open, I will certainly lose that call because if I press the green button to answer the phone, the mixer will not work, so it will not stop the radio or whatever other app to let me hear the phone. Also, most likely the system will be setup with no sound mode (showing a forbidden musical note), so I won`t hear anything. The only way to answer a call is to start up the phone app, then to go to Bluetooth music and wait for the call... But even this way the sound is very weak.

(3) Radio or any other application playing music won't fade out to let the phone app handle the sound.

I updated my system from 2.6.70 to 2.7.11 hoping that will change anything but it's not the case.

I have a feeling that these issues started when I connected my reverse camera... can that be? I will try have it disconnected, to see if that changes something but I am not too sure...

Thanks for sharing any thoughts,

[Android Head-Units] booba5185:
Did you try the fix the first post says? Something along the lines of opening Radio and hit\hold back. As far as the squawks, that's first first I've heard of that at all. You can go to settings->about device to see what version your unit has (MCU or firmware). It might need an update.
[Android Head-Units] MFKinSINY:
If yours is in fact identical to the one on the first page of this thread (as is mine) at the very least make sure your MCU ends in "01"

Those two digits (according to Miwer in post #3972) identify the radio chip & the audio chip. Make sure your hardware version is correct too. You "should know" what MCU you started with. Mine came with 4.0.6-1-10-0101 and now I'm running 4.3.1-1-10-2101 (the "21" gave me color option & color app which has no effect on my unit with blue leds, not rgb leds) but there was never an update for -0101 so I took a chance. The -1- is the hardware version. Make sure yours is correct. (maybe there is some kind of identifier like on the sticker, or inside the unit)

The -10- is the vehicle make/model (see the post I mentioned above)

Like I said, the last two of the four digits are the chip identifiers and can affect your audio & radio. The first two of the four digits are your "features" and may knock out bluetooth and/or your DVD amongst other things if not correct. You definitely "should know" the MCU you started with. MAYBE (I'm not sure) a factory reset would get you that MCU version and you can update firmware & MCU from there as well as reinstall any apps. AT THE VERY LEAST make sure your hardware version and your chip identifiers (and also your features) are correct. The first group of numbers (before the -1-) is the software version and the higher the number, the newer the software (or should I say "MCU" version) IF your unit is the same as mine, you'd probably be safe with 4.3.1-1-10-2101 but I cannot say this with 100% confidence. Good luck!!!

Thank you for any thoughts,

[Android Head-Units] booba5185:
I responded to your post and I believe someone else did as well. It was kind of a long explanation so let me go quote myself, one second.

Edit: I guess it never got posted. I typed it up, but where it went? I dunno, lol. Anyways, it's not going to happen. Android never goes to sleep when you have this option selected. IE: It has no idea anything changed at all, Android continues running business as usual. Even the external amplifiers stay on, the MCU just stops the audio output going to them.

It sounds like you started your car while listening to music and got the MCU and Android out of sync. Try hitting the reset button on the front of the unit. I believe you have the same unit I do, so it's a pinhole button below the eject button. That symbol means nothing, mine has that symbol all the time.
[Android Head-Units] MFKinSINY:
Yours came with an ir remote control? Try toggling the mute button. Check your system settings under audio?

I noticed, while mapping panel buttons that there is an "audio off" selection that can be mapped to a button. I don't know what it's for, but apparently you CAN turn off audio. hmmm

When did this appear? Did your radio come to you this way? Or did you do an mcu change or firmware update? Did this appear after you installed an app? Are you using an 3rd party audio controls such as VIPER?

What have YOU tried so far to fix this? What firmware you using? What MCU you using? Give us some help so that we can help you.
[Android Head-Units] booba5185:
Mine has had that icon since I bought it, I always though it was because I wasn't using an MCU app so the MCU assumed there was no audio and displayed the icon.
[Android Head-Units] KID52:
Actually I have been experiencing exactly this issue. The way you have described it is probably better than I would, to me it sounds like a CD skipping. Sometimes it's scared the crap out of me with the music turned up loud.

I thought of a few possible causes, but haven't been successful.

Poor quality memory card - replaced my cheap card with an expensive branded card, no difference.

Corrupt files - Playing files from the card on my PC has no issues.

Now, I have noticed something interesting. The squawks as you put it, only appear when I am using a navigation app in addition to playing music. If I only use the default music app and no navigation (haven't tried just RocketPlayer yet) then I haven't had any issues (so far), but as soon as I open up a navigation software (iGo, Waze, etc) and play music, either through the default app or RocketPlayer, I experience the issue.

I realise this doesn't help to solve it much, but hopefully someone may be able to suggest something to try.

[Android Head-Units] donnieSJ:
Yes I have the same one as in the picture. Thanks for the reply, here is what I have for designations:

CPU RAM yadda yadda

Android 4.1.1

MCU 4.1.0-1-10-0101

System 2.6.77

DVD 2.13.11-hd860mc

When I got the unit of course I was excited and didn't write anything down as to what firmware it had when I got it. I don't think, though, that I did anything with the MCU. I did put the latest system software on, which I didn't like because the home screen was too distracting. I like the static

icons at the bottom of the screen so I reverted back to 2.6.77. I have since upgraded the radio alone to the more modern look. Also when I changed the system software I lost Sygic so I have a cracked version on there now. I understand the units shipped with a pirated version of Sygic anyway am I right? Or maybe just a trial version.

Interesting bit about Sygic, I was using an auto brightness tool called Auto Brightness Manager from Playsafe that I liked because it was simple and followed our sunrise/sunset. Trouble was it caused Sygic to randomly drop the nav signal and thus became rather annoying. I tried other nav programs but nothing compares to Sygic so I am looking for a new brightness controller.

One last bit for now: 2 apps to look at, Fuelio and GPS Essentials. Fuelio is cool because you record all your costs (I have the paid version) but it needs a dark theme. The developer responded to my suggestion on this and I was impressed by that. GPS Essentials has everything a navigator could ask for including a neat-o compass that you can "clamp" to your GPS antenna so it works adequately even without actual compass hardware. One other app, Tide Prediction by Muchoviento.net is very useful to me because we live on the Bay of Fundy which has the highest tides in the world (54 feet at some points, 28 feet where I live) so I am always curious about what the tides are doing.

All that being said I might try that MCU firmware and see if it clears up my sound artifacts. Another user suggests that it may be a conflict with Sygic so I will investigate that as well. Apologies for the lengthy post.

Don

---------- Post added at 06:02 PM ---------- Previous post was at 05:53 PM ----------

Very good, a solid clue. I'll try that next time I go for a drive and see what happens. Maybe the nav software and the music player are competing for resources. Good info for the tech guys out there dissecting these units. This is cool...
[Android Head-Units] sciallo:
I tend to disagree, something tells apps about standby... Wifi stais on (which I like so I can still sync files) but pandora for example pauses/stops, also, checking with a meter when I had my unit on the desk I could see both p.ant. and p.cntr wires loose 12v. which should turn off external amps (if wired correctly) and lower power antenna or shut off antenna preamp... This in fact caused me to start designing a usb relay to keep usb hub powered while in "sleep" and still shut it off on powerdown... (I'll post that once done in the hardware mods thread)

I might try other players to see if it's only poweramp, perhaps someone with other player can chime in, I forget what other android app I noticed stopped as it should... I'll be experimenting a little more, any more input/experiences would be appreciated
[Android Head-Units] booba5185:
That's strange. My unit leaves the amplifiers on when in standby, that's why I couldn't use couldn't use that feature anymore.
[Android Head-Units] Skratchuk:
I have been using Rocket for a while and fairly happy with it my only dislike is when you shut the power off before stopping it, it doesn't remember last played position usually remembers the first track you first played last time.

[Android Head-Units] VMontreal:
Thanks Booba.

I can tell that it used to work fine when I installed it the first time but when I installed the reverse camera I made many tests with the camera connected on various Video inputs (... and maybe outputs as I was not able to read the labels properly).

Anyway, the good news is that the reset fixed my phone: now the sound of the other apps is interrupted when I answer an incoming call and the communication goes well. It did not fix the sound for 3rd-party apps such as VLC and MX Player, but it`s not that critical. I will try reinstall them and see if that changes anything.
[Android Head-Units] booba5185:
What version firmware\MCU do you have installed? On mine, it SEEMED to make that problem happen less. My unit does all kinds of unique things though. Have you tried opening the Radio app and hitting the back button on the lower right of the screen? Most of the time that'll "grant" sound privileges to the 3rd party apps.
[Android Head-Units] VMontreal:
Thanks for your help.

Yes it comes with the remote. Apparently the remote is fine but its mute function is not different than the mute function on knob1... It works but unmuting it will not fix my issue.

It worked fine at the beginning but when I installed the reverse camera it start freaking out like this... It came with 2.6.70 and it started to have issues. Then I updated to 2.7.11 but that did not change anything...

Well, things I tried include starting the 3rd party video apps (VLC, MX Player) or even iGO after I started and closed the stock apps such as Video, Music, DVD etc...

Then I rooted the device and updated the firmware to 2.7.11, then rooted again...

But the thing that really changed something was resetting the device as per suggestion from Booba. It did not bring the sound to 3rd party apps but it fixed my phone which is major improvement to me. Before this i wasnt able to pickup the phone as I could not hear the voice. Now, after reset, it works. I was afraid to reset as I thought it will erase the apps I installed.

I also have this symbol. The symbol appears with applications of 3 people. When this symbol appears the sound is very low. I have tried several mcu and the symbol goes well. If you try in settings, sound, you have to deselect the marked (front left and right speakers) select all, the symbol goes well but the sound is fine. The problem with this is that the radio does not listen. I have not found the solution.

There is a system setting in the "audio" sub-section. Make sure is UNCHECKED "mute while in reverse"

Its possible the radio thinks you are always in reverse (due to improper hookup of your camera or something went sour inside like mine, mine no longer switches 12v on the remote on/off wire AND the p. antenna wire) just stopped working one doy

Also, try different priorities settings. Mine works best set to "intelligent" but you can try the other two settings (system audio or 3rd party audio) and see what happens but in my case "intelligent" does what i need.

gapps

What exactly do I need to install to have complete/proper functionality of google (maps, contacts, etc.)

What are these "so-called" gapps I hear about in this thread?

My primary goal is to use the voice search feature to dial my bluetooth connected (non-android) phone.

I wanna say "call Jason Smith" and have it dial that persons number. Is this possible?

I don't have 3G directly connected to the head unit, so it does not "act" as a phone.

Yes actually that is a general gripe I have with this unit. It does not have a way to remember the state it was in when it was shut down. Maybe that's an android thing but it sure would be cool if it came on the same way it was shut off every time you jump in the car.

Thinking about that now for a second. Maybe there is an app that does that. I suspect if there is one, it might not play nice with the MCU. Anyone have any experience to share in this area?
[Android Head-Units] VMontreal:
Thanks, that was unchecked since I installed the rev camera... I have also unchecked the beeps on the keys.

Yup, that made it... In my case it does not work when it's in "intelligent" mode, but works as expected in 3rd party audio. So, once that I switched it from intelligent to 3rd party, I was set. Now everything works as expected, I guess:)
