I think in one of the other threads it was mentioned that it stays on for an hour with no way to adjust that.Maybe I'm premature on this but it appears all of my usb and usb-c ports stay on without ignition ON. I just bought that ottocast wireless carplay and the blue light stays on all the time.
Any option to turn off?
Yes, that continued connection attempt to your Apple smartphone is real "annoying".This is incredibly annoying when you return home and the CarPlay adapter continues to connect to your phone preventing your phone from shifting to home Wi-Fi for an hour. Would be great to have an option to disable the USB when the car is turned off.
I live in the country where there is minimal cell coverage. Not switching to voice over Wi-Fi immediately when I return home means dropped/missed calls for an hour. Since my home is also my office, this is untenable.Yes, that continued connection attempt to your Apple smartphone is real "annoying".
An option would be to install and use a Power and Data ... Male to Female USB Cable Adapter with an On/Off Switch inline with your CarPlay adapter. (Cost $12+-)
You would flip the switch on the inline switch to off, when you exit your JL. When getting into the JL, your flip the switch to on.
