I want to purchase the rcd330plus with the wireless carplay adapter, but I had a question – do I need to keep the wireless carplay adapter permanently connected to the USB port after pairing?
Yes. It must be plugged into the USB port to work. So some people call it a wireless carplay dongle.
In order to be more beautiful, I modified the rcd330 plus to the rear USB, just to better hide it.
Except that it needs to be paired when using it for the first time, it will automatically connect when using wireless carplay again.
