Hi Howard,
I’m curious if the K6 turns off or just loses connection when you turn off the ignition. If the K6 switches off, this is because the K6 is given the ‘command’ to switch off by the yellow wire (ignition switched).
My Samsung remembers the last used WiFi connection. The connection to the K6 is then automatically re-established when the K6 is turned on. Only if I have had another WiFi connection, for example my home network, do I have to manually rebuild the K6 WiFi connection. The WiFi password is saved, so I don’t have to enter it every time.
