My 24 was built the 2nd week of the 24 models. I still don't have turn by turn in the HUD.

 

Okay, I may have some light to shed on this after a 3-day, 26 hour, 1500 mile trip with multiple stops and destinations. This regarding the truck in sig:

• Apple iPhone 15 Pro
• Wireless CarPlay
• Google Maps

It only shows on the HUD/Dash* if you get directions AFTER you've started the truck and connected to CarPlay. Whenever I got the directions BEFORE getting in the truck I did not get turn-by-turn on the HUD. The only thing I didn't test for was whether I got directions from the phone as opposed from the CarPlay screen - I only ever did it from the CarPlay screen. It MAY be that getting the directions on the phone (whether connected to CarPlay or not) is the trigger.

*I get TbT in both places (or not) simultaneously.

 

I also have a '24 early build Lariat Ultimate, and just like yours it did not have nav directions on the HUD. For me, it was a one line adjustment in ForScan, line 50 (labeled "Navigation Display on HUD") in the spreadsheet:

Just ticked that number over, and now it works with no issues. I use google maps via android auto.

 

Finally got time this weekend to mess with it.

Can confirm the Forscan adjustment for a Gas engine works for Android Auto on a 2024 Lariat Ultimate.

APIM (Navigation Display on HUD) 7D0-05-01-xx-xx change the '1' to a '2' for a gas engine.


Once you get past the upcoming turn, the direction get smaller and move to the lower left of the speedometer until you get closer to your next turn.
