ROM Update for Globalsat BT-338 to ROM 3.1.1

ROM Update for Globalsat BT-338 to ROM 3.1.1 (Bluetooth on PC required to update your BT-338 Sirf III Bluetooth GPS)
ftp://xda:[email protected]/Uploads/Globalsat BT-338 ROM Update to 3.1.1/
What the upgrade fixes
* Upgrade your receiver to allow the SiRF III chipset to be WAAS/EGNOS capable and activated via the “GPSinfo or SiRF DEMO” utility software after upgrade.
* Improves acquisition and also improves bit sync capability and recovery mode. (This error can cause fix problems from reacquisition after a blockage from receiving data also know as the ‘jet-lag” symptom).
* Improves cold start frequency search range problem, where frequency was not searched properly after 30 seconds.
* Improves potential cold start visible list problem, which could affect performance if all satellites are below 32 db-Hz
* Corrects Message “41” datum field.
* Corrects date stamp not updating.
* Limits the 50 BPS thresholds to 27 to avoid undetected parity errors, which can give position errors.
THIS FIRMWARE UPGRADE WILL NOT:
Change the “Auto Shut-Off” to activate after 10 min if no Bluetooth connection is present to conserve battery life. :twisted:

A cautionary tale :O
I bought one of these recently and despite the dealers assurances that it had the 3.1.1 firmare on, it didn't.
So I decided to do it myself with the aid of this firmware. I've done plenty of flash upgrades and wasn't bothered about all the usual cautionary tales. about 55 blocks into the initial erase procedure the software reported a connection error...............and that was it :shock:
Interestingly enough the bluetooth still functions and I can connect but there is no data being produced and the green GPS light doesn't come on at all. I've tried reflashing but I just get a communication error.
So it's back to the dealer as a dead unit Just wish he'd supplied me with what he promised to to start with. The depressing thing is I'll have to wait for them to check it's faulty and when they replace it I'll probably have to return the next unit because it won't have the 3.1.1 firmware either and I can't risk killing another unit.

Hi, it seems there are different versions of this firmware, i currently have the update for "GSW3.1.1LowV 3.1.00.07-C23B1.00"
Does anyone know, where i can get the "GSW3.1.1TO_3.1.00.07-C23P1.00" firmware?
Note the LowV/TO and B/P in the firmware names.
The one i have is worser than the 3.0.2
Note: I can't download the file using the link above (I've been time travelling )

MTCD clock resetting issue (13:00)

I really don't know if this is a general issue or there is something wrong with the unit (MTCD GS - Xtrons TL702AP) that i have.
Namely after each hard start (leaving it off overnight), the unit resets clock to 13:00.
I tried disabling GPS and network synchronisation, but to no avail... It boots up with 13:00..
The BATT wire is properly hooked up since the radio stations remain.
The other problem is that also the GPS does a cold start and takes forever to get a fix. Leaving the GPS sync on takes sometimes until "13:30" to correct the time.
Is this normal?

In my case a cold boot repair resulted in a 6:00 time ...but after 2-4 minutes I got gps fixed and therefore time synced.
I think the 13:00 is due to the time zone (you can force the time zone)
With respect to the gps fix....what ROm version do you have? Perhaps you need to upgrade rom
Enviado desde mi D6603 mediante Tapatalk

Yeah, the 13:00 is due to the timezone - it may be 0:00 in China... the date also resets to Jan 1st 2016.
I am running the MTCD GS 1.96a_1 (Nov 8), which came with the unit. Xtrons also sent me the "latest" version, which is the same.

could you find a solution?

Well, never buy a cheap Chinese product again.
In my case, there was basically no real technical support. They did offer to replace the unit, but the new unit is the same. It works, I can't say that, but that's it.
We don't have any metalization on the windscreen and the GPS receiver is positioned directly looking at the sky. It takes forever to get the fix (can take up to half an hour) and even after that, the GPS position quality is sub-par. Navigation software (Sygic) often has problems tracking the roads, GPS speed is reported in m/s without any decimals and the speed in km/h (or mph) jumps in large steps of more than 3 km/h. The unit often crashes while in idle and does a cold restart as the result, resetting GPS and time in the process. Radio reception is bad on these units even with additional signal booster.

Clock problem

Hi, I have an px5 xtrons and a problem with the clock on Android 8 (stock and malaysk rom) When I restart the car the unit have the old time of shutdown. (Unit connected to battery and no problem with android 6) Canbus is set on my model car and I have this problem, but if I set canbus model to none the clock works ok. I try to change canbus box but same issue. Anyone have a solution? Thanks
edit: even with the last malaysk android 6 rom same problem. Is it possible to solve putting downgrade version of clock app?

I've had the same issue for probably the past year or so when I first started playing with custom roms. I'm pretty sure it happened after doing an MCU update. I have GS PX3 MTCD running hal9 rom. I've tried disabling network time etc but no difference.
When booting the headunit the time appears to be correct, then it changes to the wrong time, then after a few mins when either GPS or wifi has got a connection it corrects itself. I haven't tried changing the canbus model in factory settings as it's already correct.

I've found that the Clock app from Google works. All other including the stock clock keeps the shutoff time.

same problem here after upgrading Xtrons PX5 unit to Android 8.... it seems that somethings changed in CAN-Bus communication. Where bevore the car could write the correct time into the HU it's not possible anymore and the wrong (stucked) time get written into the Dashboard. The time will not synced when the HU is in standby (fastboot)... but will synced within 1 minute if i make a full boot.

hi, can you explain in more detail haw you managed to make clock work with google clock app?
i have installed it but no changes. the clock still shows old shutdown time

Hi I'm having the same issue with my xtrons head unit. Did anybody figure out a fix for this?

Hello,
I have the same problem. I have tried to add clock app to the whitelist, (mtce-utils) but It doesn't work. The canbuis I don't know is working correctly, Torque applicacion can not detect ODB unit and I can not view any value.

I set the clock to get the time from GPS only and I ve never had a problem.

Yes, but it only works if you have GPS connection (outdoor). If you are into garage there is no GPS udpate.
I have XTRON PX5 unit with Malaysk 8.0 and I have set the following things on whitelist:
com.android.settings
com.android.providers.settings
com.microtek.hctwidget
com.android.deskclock
com.cyanogenmod.lockclock
I have used mtce-utils ehitelist and Graser Daisata Xposed modules and none of them works.
I have connected the unit to the battery to avoid losing memory.
What can be the problem?
Thanks!

Same problem here :|

Android 6.0 clock also not working
As of 11/30/2018 after doing an MCU update 2.83 for Android 6.0, my clock also stopped syncing with the car's when turning it back on. It also display the last time right before the car was turned off.
Turning on/off GPS update or network update or setting the clock manually makes no difference and does not fix issue. Hope to see a solution to this.

If you revert back to the original MCU version, does the clock start working normally again? I'm assuming it would... I would just revert back to the original MCU version and be done with it. Unless, of course, there is some specific fix in the newer MCU that you needed?

Did you export you MCU config before updating the MCU ?

I don't mind reverting back to the original MCU version I had but the problem I had with that one was my audio kept going back to sounding like mono instead of stereo each time I started the car. When I played video or music sound would only come out on my right door speakers. I kept having to do a factory reset each time to get it to come out at both sides.
I haven't browsed through the forum enough to see if anyone else experienced similar issues or if there were fixes for this.

You could try the latest MCU, they may have sorted it out, you dont say what unit you have.
You could also try updating to Ore, it may also be fixed in the latest ROM.

Thanks I'll have to give it a try. My unit is the HA 2150 V600 with the px5 chip.

HI did anybody manage to sort the clock issue out on the headunits thanks

I have been having this same issue for a long time and hoping to find a fix for it.
I have tried the Google Clock app, that did not work.
I have updated my MCU from Ver 1.81 to 2.65 to 2.75 and now on 3.0.1. None of these MCU versions fix this issue.
I have also tried the V2.75_sp and no change (Did not think this would help with this issue, but tried it anyways)
On each of the MCU versions above, I have tired multiple roms (Stock, Malyask and Hal9K) and no luck fixing the problem.
The only time I have been able for this to work is if I have wifi enabled and connected to a Hotspot and Network time sync selected in the settings/Date&Time. With this configuration the time sync works everytime.
Now when the time does not Sync and if I open the GPS Plus app, the time displayed in the app is correct. So based on this, the only thing I can think of is that somehow the time from GPS is not being pushed to the clock app.

Guys I think I found the solution, at least it works in my case. What happens actually is that the unit is set to autosleep and not to shut it down. So when the unit goes to sleep, everything freezes including the clock time. When you put back the key contact, the unit goes back to live and all the apps start again from the moment when they went to sleep.
The solution which seems to work in my case, is to set the unit to shut down after I turn off the engine. Of course, it takes around a minute to turn on back when I put the contact key, but because the whole unit has been shut down, when it starts again it checks also the time clock and it syncs with either the GPS time or with the network provider time zone (depends what you have set). In my case I use the GPS time zone and with this workaround everything works well now.

It's not so much the MCU updates but the actual system update. Going backwards to the 20171214 system update will get the clock working fine again and should work with the most recent MCU update (my instance). With this version I didn't have to bother with changing the auto sleep or shutdown settings since it's an inconvenience to wait for a full minute for the unit to boot up. Also did not have to change GPS or network time sync either. I turn the key ON and the clock just works right away.

Seicane Android 9 won't update time after turn off engine

Hello all I need help!
Just bought a seicane H286 MTCE_HF_V3.07_1 9" android 9 everything looks good except for the clock. everytime I turn off the engine and the time is 2:15pm, when I turn the engine back on 30mins or however long later the clock is starting at 2:15pm and counting. I toggled update time with GPS on/off, I toggled update with carrier on/off but nothing work. The only time it's update the time with GPS is when I reset the unit. really frustrating with tech support they keep insisting that the unit is automatically update time with gps! If anyone have any solution please help. thank you.

Yes, this is a known issue, search forums for details on update or contact reseller for support/update.

hello, even my autoradio (wondefoo) rh3368 mtce_cz, cpu octacore cortex-a53 @ 1.5 android 9 has your same problem ... surely there is a software bug, the seller told me that he will send me an update. .. ps to the most expert: is it possible to downgrade from android 9 to 8 without risking ?

I recently purchased a 10.1 Seicane H2038 rk3368 unit that seems to be using the same MTCE_HF_V3.07_1 firmware. I also had an issue with the time being incorrect when returning from sleep. I was able to correct the issue by updating the android OS to the latest available (in the Daisata updates thread) HA_px5_9.0_ota(20190521) - please note that that this performed a data reset when applying.
There appears to be a newer PX5 HA_px5_9.0_ota(20190528) firmware posted now that I have not tested, but I assume that should work as well:
https://forum.xda-developers.com/an...asaita-mcu-updates-rockchip-px5-octa-t3575155
I did not upgrade the MCU firmware.

If I know how to root it I can install clocksync and have it automatically sync the clock to gps signal

yesterday I installed the version ha_px5_9_ota and the problem of updating the timetable has been solved, the only problem is that as equalization power and audio volume is less than the original rom.

I solved it by rooting it and using tasker. What I found out was whenever I toggle location on and off the timeupdate to gps time, so I used tasker to toggle it.
First I rooted by using adb method found here: https://forum.xda-developers.com/an...5-mtcd-e-head-unit-discussion-thread-t3734189 (very helpful to watch the youtube video)
be sure to install hacker's keyboard from play store and use notepad++ on your pc. not sure why regular keyboard didn't work in terminal emulator. I had to root twice for it to work.
install tasker, in profile I set "Display State" to "on" so every time I turn on the car it'll run the task. In task I set it to wait 5 seconds, turn off location, wait a second and turn it back on.
go back to adb on pc and run command: adb shell pm grant net.dinglisch.android.taskerm android.permission.WRITE_SECURE_SETTINGS
that's it! now whenever I turn on the car it'll take a couple seconds to set the correct time.

hello, I have finished configuring everything and I must say that I am very satisfied with this version, if I can afford to give you some advice ... try installing it also because it seems better to receive gps satellites and do not need other applications to update the 'schedule.

Any body have any version of mtce_hf plz

Hello everyone. I received an updated Firmware directly from seicane for their head unit. This is Android 10 update for the 2/32 GB unit. Everything seems to be working great so far on unit. If you would like to try it for yourself please feel free to download and install. I'm not too tech savvy so if you have any questions I'll answer them the best I can. Thought I would share for anyone to update their own unit if possible
PLEASE BE ADVISED YOU USE THIS AT YOUR OWN RISK!
I will not be held responsible for any damages done to your own unit.
Thank you!

A-Media android car system tracking me

Hello there,
I've bought a second hand car with the chinese A-Media android system in it. Could it be the system is storing data about my driving routes? No matter how many times I try to disable the location function, it keeps turning on everytime I restart the system or better to say the car. Have also tried to disable as much apps that weren't necesarry for me, but some seem to be not deleteable (e.g. something like a GPS coordinates app? ). The previous owner was a company that used the car for their business.
How can I solve this, and is my feeling of being tracked / data being stored in the device/car real? Thanks!

Of course it's tracking you it's an Android system. If you have any concerns about the previous owner you should do a factory reset but since it probably came with some "special apps" you should look for the original firmware or root it and extract the apps. If you can turn off the GPS in settings just turn it on when you need to use it.

thanks for your info. It just bothers me that Location automaticly turns on when I start the car. Who says me some app is not spying on my location ? Turning it off in Settings does not work. Turns on automaticly every time at startup.

If you can't turn off the GPS from the Android settings you might be able to do it in the factory menu. Don't forget GPS and location are 2 different things. Do you know which HU you have?

I didn't knew it were 2 different things. What do you mean by HU ?
When I try to enter factory settings it ask for a password which I dont have.
Some info:
Model numer : A-MEDIA AUTO ( 1024 x 600 W )
Android version 6.0.1
Kernel Version 3.10.0 [email protected] # 1019

You should be able to find lots of help for that unit. Sorry HU is head unit. Try 1260 for the password or maybe 8888. Refer to it as MTCD KGL and more people will know what unit you're talking about. Try not to change too much stuff in the factory setting it can make the HU stop working.
