1 month ago Thanks , but putting tape is not the proper solution ? is there any way to control from software ? Also it will engage both the USB ports

1 month ago It is similar to commonly used USB Y Cable. The difference here is the power received only from non-data cable. Unfornately such cable is not readily available in the market so we had to tape it and make custom one.
As far as I researched there is no way to tell Pi Zero 2W to consume power only from PWR port.
It will use power from the non-taped USB port and data from the taped USB port.

3 weeks ago @sivachandran I too own a creta 2019 I tried with Pi zero2 w and it shows the wireless aa connected and bluetooth also connected it briefly shows AA connected on phone but nothing happens on the screen and then goes back to looking for AA connection. Any help?

2 weeks ago Sorry, I never faced this issue. Did the car unit showed anything?

1 week ago Thought I'd share some of my findings
Planning on replacing my pi zero 2 with a pi 4 to solve some other teething issues with lag and stuttering, so I've ordered this cable
The plan to either tape up as mentioned here, the data pins on one plug and tape up power pins on the other,
or even better attempt to see if I can fatigue the metal pins and break them off near the base inside the USB A side with a craft/ Stanley knife, so break data pins on one, and power pins on the other
Anyone looking for a similar cable for the pi zero (micro usb) this one should work!
I apologise If there not country specific to you but should at least give you enough info to find them local to you!
Let me start with big thanks to @nisargjhaveri and the contributors. This project has made my day-to-day Android Auto usage a lot simpler and smooth.
I own Hyundai Creta 2019 model. It comes wired Android Auto which I converted into wireless using Pi Zero 2W and this project.
The problem I had was Android Auto USB port not getting powered off even when the vechile is powered off. I waited for 1hr but it doesn't seem to cut the power off. In my calculation, with the idle Zero 2W power consumption, it wouldn't impact the self-start until the car is not used for approx 7-10 days. But I didn't want to take the chance. So I did some research on the Internet and came up with the following USB connection setup to power off the Zero 2W when the vechile is powered off. I'm sharing the info here so that it might help others.
USB Connection Setup
You can skip the USB Hub if you don't have Dashcam or other use for USB port.
USB Cable Pin Layout
It is important to mask the USB 5VDC pin to stop Pi Zero 2W consuming power from Android Auto USB port. I used Cello tape and Tweezer to get the job done. Connect this masked USB cable to the Android Auto USB port.
Hope it helps!
