Can you precondition on roadtrips without using Ford Navigation?

NO.

Wrong. Please stop spreading lies. The battery receives additional cooling if the temperature is hot and you are navigating to a DCFC in FordNav. This is easily verifiable via OBDII readings for battery coolant and temp.

Thank you.
I’m still trying to figure out if it’s as a charger issue, battery issue, or software throttling charging speed due to temp issue.

Temp is the number one reason for DCFC speed to slow down. Too cold, can't charge fast. Too hot, too dangerous to charge fast. If you see a DCFC limping along around 35kW, that is likely a station issue. That's what they derate to when a temp sensor for the cable fails. Otherwise, the truck (or any EV for that matter) is protecting itself from getting too hot. A good way to see this is to use an OBDII reader and look at the amps requested compared to the amps received. If it's requesting more than it's getting, the problem is with the DCFC. If they are about the same, truck is slowing down due to battery temp (or high SOC).

I would be surprised to learn that there is a problem with the software. If there is anything wrong on the truck with charging, it's 99% of the time a hardware issue. And those usually give you some sort of indication (a warning light or red rings while charging kinda thing).
