Well my friends, I would not be so sure...

Of course, I can be wrong, but look here why I have my doubts:

1. My unit, right out of the box, had an MX2 MCU, I don't remember version. I've updated to V2.79, also MX2, because I thought I have to respect all those letters. Until that moment no car logo on my boot screen. I didn't know about this option. When I found on the forum about factory settings and how to get there... big surprise! I've found the boot logo settings and since then I have my car's logo when the unit is starting. And I have MTCE_MX2_V2.79_1 MCU.

2. A png file of 600px/300px with my car logo is about 70KB. In the MX file it's suppose to exist a lot of logos, so even archived, we are talking about some hundreds of KB. Now look at the MX and MX2 MCU files dimensions:

- MX img file size - 233,229 bytes

- MX2 img file size - 233,229 bytes

:confused:

See the attachment to see the binary comparison between the two files. There are 4 colored zone in that htm file. Those are the only differences.

I've used WinMerge.

I think is too less to be the logos library which makes the difference.

Don't you think?

And btw, just regarding the files size, where are the logos stored? Because there is no size difference...

So finally, as long as I have logos with a MX2 file, should I upgrade to v3.0 MX or MX2? I wonder...

[MTCD Android Head Units General] LinkseD:
If you update with MX2 and dont get any logo after, just switch to MX then. Easy as that, makes literally no difference...

I myself switched from MX2 to MX because I had no logos.

Sorry guy's, I hope someone can help me out with this Android head unit for my Cadillac XTS. Since I bought it from the seller, I've been having a bunch of issues, I sent them message after messages how to fix it or upgraded but nothing as of yet.

My problem is Everytime there is this white box in the middle of the screen, you can't really X it out, it just there. Also please need to update it, but seems like I can't find the right software update for it. I attached some pictures below of the head unit info also a link of the eBay seller where I purchased it. Thanks a bunch.l

for me, going from GS 3.01_03 (obtained officially from xtrons) to GS 3.07_03 (from yadi) made FM reception worse.

there's probably lots of testing (not ready for release) MCU versions being leaked around, i'll stick to the one provided officially from the vendor.

Hi I currenty hace android 7.12 with mtce_xrc_2.66_1

Thank you.

hmm, i'm on mtce_lm_3.07_1 and i had nothing better to do than go to factory settings and change "customer version" from 1 to 3.

the unit restarted and it never came back up, it's a black screen, no light, nothing....

i'm looking for a pin to reset it and hopefully get to recovery, maybe unplug it from ISO connector also.

any other ideas how to revive it? :)
[MTCD Android Head Units General] zerozoneice:
after current gets cut off from the car (5-10min after ignition off), the unit starts (wakes up from autosleep) and plays radio (where i left it before reboot). Touchscreen and buttons lit up and work ok. However after less than 10 seconds, it shuts down and never comes back up. I tried to quickly get back to factory settings but as i was entering the password, it shut down.....

Anyone can post please a dmcu.CFG from a LM MCU with version 1?

Mine is a MTCE_LM_v.3.07_1 (important to be 1 after the underscore). I'll take any LM MCU as long as its version 1.....

Hopefully i can upgrade it blindly from recovery or something...

MCU version ?

FWIW I just got a Chinese White label ( I dont know the MFTR) PX5 with a strange MCU version

It has a MCU version that maybe be newer ( undocumented ) than those posted : MTCD_LM_V2.62_1 with timestamp Sep 6 2017 15:42:31

It has the A53 CPU , 32 GB Storage , 2 GB Ram .

Further Device Information attached

[Edit]

It transpires the lettering LM within the MCU version ( LM 2.62 ) denotes that it is a 'Erisin' HU , though I have not found any newer MCU stock firmware for this device . There is a a thread with a mod version ( sound patch ) here for LM devices but its for units with DSP and not sure if this has or not

Subwoofer

Hey guys,

I have a Isudar PX5 head unit

I have the amplifier connected via RCA to the 'Subwoofer Out' connection on the radio.

Everything works OK at first, but after shutting down (turning off car/leaving car), the output is not working. I can hear the subwoofer just 'throbbing?' But no respons.

Only way to get it back to work again is to disconnect the radio from the car and reconnect it. (Now i am taking out the car's radio fuse and putting it back in).

I have MCU :

MTCE_GS_V3.17_3

Can anybody help me with this issue ? ? ?
