MCU updates - how far do they go?

Hi Guys,

Quick question, it seems that the MCU updates are mainly for hardware compatibility with the Android system installed (they don't include any other firmware updated such as Can bus drivers).

Therefore there is no hope of getting any of these android based car sat nav's system to ever to work fully with the cars can bus (unless your lucky and it worked 100% straight out of the box)?

(That's not saying the MCU updates are not important).

Thanks for help.
[MTCD Android Head Units General] typos1:
It depends what car you have - VWs are the most supported, a lot of cars only have basic support.

Some people have modified apps so CAN Bus works better - if the basic CAN Bus protocol of your car is in the app/MCU you can in theory write your own app.

The MCU does contain some CAN Bus data - the list of compatible vehicles is often updated with a new MCU.

Yes indeed you could write your own app, but this would require leaning how and knowing the coding to be able to talk to radio MCU, and the Can Bus codes. Better still correct the mistakes in the supplied app (which is impossible from what I understand) they provide with the head unit which seems to be not fully compatible with Europe as they claim (i.e. missing the option for mpg fuel unit for the UK and the temperature unit °C bug).

The only reasonable solution of correcting this would be the author of the 'car setting' app to re-issue a corrected updated version from the original code.

upgrade MTCD_GS.V1.61_1

Hi,

i've been trying to upgrade my car radio but im having troubles.

First of al its hard looking for the right version. The most recent i've found is GS_2.72.

But there are a few things i dont understand. Why are the images so small? The 2.72 is only 218KB.

I thought flashing software would be at least 800MB.

And these images...are they tweeks for the current android?

Because i would prefer a newer version of android on the device.

Any help or redirection would be appreciated.

Wifi fails to start on resume.

Hi,

I have an MTCE_WWW_V2.80_1 (March 1 2018)

I've read through this thread and I'm happy that this is a KLD unit and how to upgrade the MCU.

My reason for upgrading is that every now and then after resuming from sleep my wifi fails to detect any networks at all, this is fixed by a reboot.

Is the wifi chip managed by the MCU? Eonon have sent me software updates that change the build number but not the MCU version and none of these have fixed the issue.

Basically I would like to know if upgrading the MCU would have any effect on my wifi issue.

GS versions

Hello,

please could you help me to get the right post or download site to get the latest mtcd GS version available for my px5 6.0.1?

And, is ther some kind of version changes available? I got a GS_v2.56_1 and I would like to read all the changes made from this version.

I have read many pages at this forum, I have found other one that talks about a cross version for multiple kind of versions but after looking at the mediafire I watch an older number version lower then mine.

Thank you in advance!

Possibly, try it, its always best to have the latest available MCU anyway, so even if it doesnt help youll be better off with a later MCU.

Small update regarding the differences between MX and MX2:

I’ve been in contact with Bob from Witson. He told me the only difference between the two is that MX has the so called ‘car boot logos’ included. MX2 doesn’t have those included.

Not sure why they are no longer included in the MX2 updates, though my guess is that the MCU memory isn’t big enough to fit everything on there. ;)

According to Bob, installing MX2 onto an MX device shouldn’t give any problems.

MCU for MTCD GS

I'm running a Xtrons MTCD GS, rk3188, 5.1.1, now updated to UK suppliers' MCU 2.38_1 March 14 2017.

Stable, but no fix for Bluetooth dropping ID and failing to connect.

Then updated ROM to Hal9k V1.3 (on the forum) and instant fix to the BT issue, name and PIN display with no input from me, and connected 1st try.

Got some more config and test to do for stability and speed on this ROM but it looks good so far and doesn't use Xposed so a very simple single-step update.

I don't see any way to attach pictures or files here, but hopefully the info is useful to someone.

Richard.

Update next day...

Bluetooth will not connect at all and the BT app does not display name or PIN, so unfortunately after the 1st attempt success this is now performing the same (same fault) as the original ROM with BlueTooth. I will have to investigate more.

The TomTom / device serial number shortening is working fine, map downloaded and all running great.

Interesting! So with the MX 2.88b firmware on your MX2 device, you can choose car brand logos in the Factory Settings instead of the standard animated ’android’ boot logo?
