Good afternoon!
I have an ISUDAR PX 5 car radio
tell me how to upgrade to 10 android without removing the car radio from the car?
If I press the shutdown button, the radio goes into sleep mode.
if I hold down the shutdown button, then the car radio reboots.
How to turn off the power of this radio? how to make SHUTDOWN?
Otherwise, it is impossible to do everything as shown in the instructions.

and your instructions say:
The following are the updated steps and videos.
1. First the car radio should be turned on and connected with computer via USB.
2. Go to the factroy tool, and open the file" Update" in factroy tool.
3. Choose the " Update" file and then start it.
4. Turn off the car radio， and trun on it again with pressing the power button for 3-6 s, then loose it, and immediately click the power button again. –
This point is not working for me, since the Radio does not turn off, but reboots when the power off button is pressed for a long time or goes into sleep mode when the power button is pressed shortly.
How to completely turn off the car radio without removing it from the car?

5. Ok，After completing these steps, the computer will appear to update the firmware. Just wait for the firmware update to complete. Note: Pls connect device to PC with a short USB cable. ( The shorter the better, otherwise the PC cannot read the device).

Hello good I have the px5 model but my question is how do I turn on the radio outside the car where do I connect the power?
