Good info. I just checked Ford’s National Package Guide that was released to dealers earlier this year. It shows that the 8 speaker B&O system is available on the Lariat on the 500A package, but optional.I found this in the Canadian order guide. It says B and O is Optional on XLT 302A and standard on Lariat.
The unleashed is optional on the 502A high Lariat.
See below screen shot.
It also shows as available on the XLT, but only as optional on the 302A package.
O = optional equipment for their guide
