I am going to retrofit the IMC to the 2018 XF, but I am having issues with the built-in WiFi. Every time I try to enable or disable WiFi, IMC says "Wifi is not available". The car's telematics unit has not been replaced (so there is no connection to the IMC), but I know from the past that it is possible that IMC WiFi can work without a telematics module.

Anyone have experience with the IMC retrofit?
