Starting engine triggers cold/hard/slow restart

[glastolover]

Hi there, just fitted a new Android 9 Pumpkin head unit in a 2010 Mondeo. It is this one (SKU - AA0483S):

https://www.autopumpkin.co.uk/ford-ster ... -usb-.html

Generally really pleased with it, just a few minor niggles. The main one is about fast restarting. With ignition on and engine running or with ignition on and engine stopped, If I turn the unit off with the power button, then turn it on again, it fast restarts. If I key ignition off with engine stopped and then key ignition back on, it fast restarts. However, as soon as I key round to start the engine, it triggers a cold restart of the unit (back to Pumpkin log, and Android restart, taking ~30 seconds).

I have Googled a lot to try to find a solution but can't, can anyone help?

I read someone who had the same problem (in a different car) who said manually turning the unit off and then manually turning off after engine start worked for them. I have tried this, but for me, cranking the engine always triggers a full restart.

I read comments that it is down to battery voltage dropping too low during engine cranking, but surely if the unit is off in "sleep" mode and ready to fast restart, this shouldn't trigger into a slow restart. It can sit there with zero voltage for hours and still be ready to fast restart!

I think there must be a solution, would really appreciate anyone who can help, as it is very annoying that the unit takes 30 seconds to startup every time you use the car, and the unit is sold with fast start capability, and clearly can do it!

Are there some settings I can play with? I found a setting "Shutdown delay when ACC off", but have tried this set at "off" and "30 seconds" and it doesn't seem to make any difference. I saw one unit suggesting this should have an "auto sleep" option, but my setting does not have this.

Is there anything I can check on the wiring? I just used the supplied jumper harness to wire in as a direct replacement to the factory fit, and apart from this issue, other functions all seem to work.

Any thoughts gladly received, thanks!

Hi,

Pls update to the newest software.
This is the firmware update.
https://mega.nz/#!uChj2Y7Z!WmZpiZ1jlyG2 ... fri-UYIP6E
Unzip the file in the root directory of the USB card, insert the USB interface, click Settings - Car Settings - Upgrade or Restore Factory Settings - System Upgrade.
Or refer to the video which does not root when update.

This is the MCU update.

Unzip the file in the root directory of the USB card, insert the USB interface, click Settings - Car Settings - System - About Device - MCU Upgrade.

I can try to do this, although I have updated the unit while connected over wifi to the latest software, will the updates suggested be different?

Thanks a lot for your help!

Hi,

After the update, some problems can be solved and the car stereo can run more smoothly.

Hi there. I did the update you suggested, though I was only able to do "Update MCU" in the Upgrade menu, there was no "System Upgrade" option, 1st picture attached shows the only options I had for updating. The MCU update seemed to work though, my MCU version went from CSN2_05312019_173534 to CSN2_09112019_190520.

After this, the unit restarted fine. Strangely, the first time I then started the engine, the unit did do a fast start, but then after stopping the engine and restarting for a 2nd/3rd/4th time it was back to engine start causing a full reboot.

Do you have any ideas of any other settings that could be affecting this?

Hi,

update firmware.
https://mega.nz/#!uChj2Y7Z!WmZpiZ1jlyG2 ... fri-UYIP6E
Unzip the file in the root directory of the USB card, insert the USB interface, click Settings - Car Settings - Upgrade or Restore Factory Settings - System Upgrade.

Pls follow the steps to update the firmware. It needs a USB, it will automatically show when plugin the USB.

Thank you

Ah, OK, it has to be on a USB stick not an SD Card? Sorry, didn't realise that. Will try that tonight... Thanks for the quick reply!

Hi,

You are welcome.

OK, so I tried the same files on a USB stick and it made no difference. I still only have one menu option to "Update MCU" as per my previous picture. I have done this, and it has worked (MCU version in the info has gone up as I said before), but this has not fixed the problem. The unit still gets triggererd into a slow restart when I start the engine.

Is there any other way to do a further update?

If not, do you have any other ideas of other settings that might help?

Hi，

Can you take a video of the problem?
So we can know the problem more exactly.

Thank you
