BlueCruise will not be released in the future for the non-Platinum versions. If you look at the order guide, Platinum includes "FORD CO-PILOT360 ACTIVE2.0" vs. "Ford Co-Pilot360 Assist 2.0" and "Ford Co-Pilot360TM Assist+" for other trim levels. These all represent hardware packages. BlueCruise is a software package in addition the the hardware package needed for it, and is listed separately.
I have no idea why we're getting BlueCruise "included" with the price of the vehicle, whereas for my Mach E, I had to specify the hardware package, and (in theory) pay extra for the software to activate it, and only on a subscription basis at that.
I'm still wondering if BlueCruise is included forever. If you look at the live data for Navigation, it's called out as a three year subscription, whereas BlueCruise is listed with no such limitation.
