Jemluse Wireless Carplay Adapter Firmware Update

This seems to be obscure knowledge, for some reason so I'm posting it here. Took me finding a Facebook post to find the IP I needed to connect to do this. 

 If you need to update your Jemluse Wireless Carplay Adapter firmware, you'll be:

1. Plugging it in to USB power, so it powers up. (Don't need to plug it into something that provides CarPlay.)
2. Turn off cellular data. 
3. Connect to it over WiFi. You'll get a 192.168.18.x address.
4. Open a browser and connect to 192.168.18.9
5. Turn on cellular data. (Maybe this is optional?)
6. Look for the firmware update option on the bottom of the page.
7. Update firmware.
