Buggy ? Not really. I have more issues with my HTC one then I do my radio.

As for Google music , I am unsure, I use Amazon mp3 to buy music, and power amp to play music.

I contacted my seller and they sent me an update that they had, I'll see how it works and what version it is a little later.

Ok thanks if you can let me know, if this device support HDMI I would likely get it the Pioneer head units are stupidly expensive.
[Android Head-Units] shadowmike:
Hdmi I am in aware,I doubt it. It has yellow, red, white input, not Hdmi. What kind of chord are you using

Edit. I will be uploading the updates on my drop box and putting the links here for now until the op can edit the op

My understanding of mcu...

Like HTC custom rims .. there's system updates, and firmware updates

Newest system files will generally always work with old firmware. Same with our mcu.

The newest system files work with your stock mcu files. So there's really no need to change the mcu

4.2.6.2-7-10-6501. - 4.2.6.2 ( version number ) 7-10 ( ?? Region ?? ) 6501 (? faceplate/model ?)

You want to stick with the same model as your factory.

When you update your system, you will have new mcu files from that update. After you root your device you can access the newest mcu files ..

I still have some testing to do but, it's looking good to get a proper working mcu again

Edit.

I just installed the newest system from your Russian friend. Rooting it now

4.2.9-7-10-6501 is the newest mcu for us. However knobs are still mirrored

Radio app updated, better ui

Music app updated, better ui

Video app the same

Bluetooth/phone the same

Dvd/cd the same

Launcher2 update. Pic at bottom.

Dropdown notification window updated

Old eq app.. can someone upload eq from .77 update ?

Edit

Dropdown notification now has a quick settings type bar

WiFi on/off , brightness min/max/off , GPS button setting/remap, ram cleaner

Launcher has been updated.

[Android Head-Units] booba5185:
Does anyone know how to get rid of the hiss that comes out of these head units? I can't for the life of me to get it to go away. I've tried putting a filter cap on the power wire with no result. Weather the volume is at 1 or 25, there is a white noise hiss coming out of the pre-outs, front and rear. That and I am having a HORRIBLE time with alternator whine, everthing is ground perfectly, tried grounding in different locations, to each other (amps\crossover\head unit) to no avail. These 2 things are driving me up the wall, I'm about to shoot this damn thing.
[Android Head-Units] shadowmike:
Sounds like you still have a broken ground to find
[Android Head-Units] booba5185:
I don't, I've checked everything. New grounds on all amps, crossover, and head units. All have a sanded connection, down to bare metal. I was looking around on other forums because i know a lot of the components in these head units are interchangeable, and on a S150 forum I found something about disabling the internal amplifier to resolve the hiss problem. That'd work fine for me since everything is external, but I can't seem to find a setting to do so. in the other forum, they said to dial #*98723 from the dialer, but I can't even seem to find a dialer on this thing. I downloaded a third party dialer but the code didn't work. I figure it won't work because it's a fix for a totally different unit, but is there another way for these units to disable the internal amplifier?
[Android Head-Units] shadowmike:
You need to check your engine ground straps. And your body ground straps. Maybe think about doing to big 3 while your at it. New battery cables if they're corroded.
[Android Head-Units] booba5185:
Sorry, I don't mean to be a "done that, done that, done that" type guy, but I've done a lot of that. I've built new grounds for the battery, alternator, engine, and body, I've also replaced the charge wire with a 4 AWG, just like the grounds, while upgrading to a CS-144 alternator that produces 110 amps at idle, so my voltages and grounds are rock solid. During trouble shooting, I even grounded head unit to the battery directly as well as the alternator's ground wire (the extra one I installed). both had no impact on the alternator whine coming out of the stereo at the time. I actually thought it be worse grounded off the alternator but there was no difference at all. I'm still thinking it might still be something as simple as RCAs so I'm going to replace the ones I have, to be sure. Thing is if I unplug the RCAs at the head unit the whine goes away. The whine is only present when the RCAs are plugged into the head unit. Thanks for the recommendations!
[Android Head-Units] shadowmike:
I've gone through all of that before. For me it was the ground straps to the body. Hope new cables work. If not you may want to ask an car audio shop.

Bluetooth problem

hello, I have a problem with bluetooth. Initial work well, but now the phone is connected, you can download the phonebook, you can make a call but no sound is heard in the car speakers. I tried 3 phones, I changed the version of Android on your phone, the result is the same.

I originally had version 2.6.70 but now I have version 2.6.77

Does anyone have a solution to this problem?

Wow long day of work I didn't even realize that. However, we need to be careful how we update these units I'm sure some of us have very fragmented files .

I say this because not every update comes with every file for the radio. Some updates have 4 some have more... Any updates that are skipped leave you with potentially old drivers or whatever for certain aspects of the radio, until you install a full update.

Hi, it seems I have the same core unit except a different faceplate, it is for a Camry, here is the system info:

There are a few problems with it:

1: Cannot turn off the radio, the workaround I found was to change to music then pause, long press back button won't turn off radio.

2: Bluetooth phone does NOT work. I can pair my phone with it, I couldn't hear the other party, the radio doesn't stop playing.

Installed the .96 version and in Extra settings there is now ability to reverse the knobs and even switch them. Exactly what I was needing.

But!!! It looks like you need the updated MCU (4.2.13.... versions) and for some reason the MCU I need, 4.2.13.7.10.2501 is missing.

I can get bluetooth to work with 4.2.13.1.10.2101, but there is no knob functionality at all.

Can someone who has .93 installed check what MCU versions it comes with and if there's a .7.10.2501? Does .93 have the knob reversing ability?

I tried to route the car stereo, but the result was not as expected: after restart, the image was almost black, could barely distinguishable icons back. Some applications are still seeing correctly.

Now bluetooth works properly (do not know if the reset or upgrade ....)
[Android Head-Units] PsychoMcSatan:
I had the same issue with rooting .96 but I thought it was because i was using Nova Launcher. It made running the last couple commands in Terminal Emulator impossible as I couldn't see the keyboard. I eventually lucked out by accidentally clicking on AUX icon which gave me colours back. With previous times rooting, I only ever had to start AUX before the first step.

In any case, it might be a good idea to put your AUX icon in an obvious place or assign a button before rooting.

MCU Won't Update

Hello, I finally made the plunge and updated my system to .77. My MCU didn't appear to update. Read in the forums you need to manually do that too. So I let the unit boot up for a while. I then navigated to MCU Update and selected it. Got the popup confirmation and allowed it to update. Nothing happens. Just goes back to the menu. Done this on both of my units with the same results. I am not rooted. And zero customizations have been installed.

Why are you updating MCU? are you having a problem/missing a feature?

Seems like for a few months people were staying away from messing with MCU (after a couple of us bricked their unit) now, confidence seems to be growing back....

Model change really is supposed to be the "safe" way to update MCU as the rom *should* know what hardware you have and present a MCU choice accordingly. However, from other's people experiences, it seems there is no "right MCU" for certain units, specifically the universal unit with the volume knob on the right...

So, my suggestion, if you don't have a problem or are not missing some known feature, why mess with it?

For those who have messed with it and ended up with some undesirable effects (such as mirrored knobs or botched BT) are you harping sellers and manufacturer? Obviously there are MCU files missing in these updates, a simple use of a feature in the menu is screwing up your unit, that is NOT acceptable and they need to provide the right MCU period... start raising hell/returning your units until they do.
