PUMPKIN CAR STEREO SUPPORT CENTER

Dear Support Team,
There are some issues that I want to discuss.

1. I would like to run my car radio when the car key is put in, or the car key is in ACC position.
To let you know what I understand about the ACC-position:
There might be five situations:
1a. Put the car key in. should be acknowledged by the Can-Bus-System
1b. Turn the car key to unlock the steering wheel. Don't know whether Can-Bus-System will know.
1c. The next position is the ACC-mode. should be acknowledged by the Can-Bus-System.
1d. The next position is the Ignition-mode. should be acknowledged by the Can-Bus-System.
1e. With the next position you start the engine.
On the harness (if the pin-counting is right) pin 16 (yellow) has the permanent 12V.
pin 17 (black) is GND.
pin 18 (nc).
pin 19 (red) has 12V only in ignition-position.
So what can I do to change this situation.
2. I would like to have a view of the pinout from the car radio and a pinout from the Can-Bus-Adapter for the ND1273B-D01.
3. The Firmware (Android) is from 2017. Is there a newer one. And how can I retrieve it?
4. My W-Lan is secured whith WPA2(CCMP). I could not get connected. I had to switch off the security, then it worked.
5. Can I get an altered CanBus-Adapter where the ACC-mode turns on the power on pin 19 (red)?
Can I please get the information.
Kind regards Harald.

Dear customer,

Thank you for your post.
I would like to explain why.
First,if you need turn on the radio,you need start the engine then turn to close position,then back to ACC position.
Because that's what we do to prevent the radio direct use the battery of your car without charging and cause battery dry.
For question2:We do not suggest you reroute or upgrade any firmware if your radio do not have other troubles.
That's for long time good use purpose.
Is that OK?

Jam

Thank you for the information.
Is it possible to add to the Can Bus-Adapter one or two pins that are called "ACC-Mode" or "Car-Key in"???
This should not be a big deal because the "Ignition-mode" has to be decoded for every car-brand too.
With this possibility every customer would be able to chose his own method.
If I leave the car in "Ignition-mode", the battery runs dry too.

Kind regards
Harald

I tryed to do so as you suggested it. But it does not work.
I extended the time in the adjustments of the radio up to ten minutes but the radio switches off immediately in the ACC-mode.

Kind regards
Harald

Dear Jammy,
the car-radio ND 1273B-D01 has it only one input for the SWC?
Because all suggested pins are not connected.
And is the colour of this wire white? Or whitch colour is it now?

Kind regards
Harald

Would you mind shows us a picture?
By the way I can sure to tell you,you can't modify wire and make the radio like your original ... our radio do not support that...

Dear Jammy,
sorry to bother you again.
As you mentioned I took a photo of the car-radio and a picture of the harness. On the picture of the radio there are two wires coloured in brown whith the name "Key1" and "Key2". But on the picture from the harness these colours are missing. On the other hand there is a white wire connected with a blue wire and an open white wire with the similar connector.
So please can you tell me whitch one is used for what purpose.

Kind regards
Harald Lossner
