If I missed anyone, lmk. I was off yesterday and am trying to get caught up on several threads on this and another forum.

 

so if I do an hour and a half drive and start the update, will that help? I don’t have the ability to plug a charger into my truck.

 

In past I have gotten updates on longer drives. One as recent as a week or so ago.

 

Without a charger, a nice long drive is the only way to charge up your battery enough to hopefully get it to work.

 

Received 4.3.5 on the 14th and 22-PU-1009-PPO-SI this morning. The last one prior that I am aware of was 4.2.4. So I think it skipped 4.3.2, 4.3.3 and 4.3.4.

 

So does SYNC 4 have any kind of navigation with no subscription? My 2020 XLT has navigation and no subscription required, but you have to update the maps with a USB drive (which is free).

 

My job 1 did the same thing.

 

Add me to list of 4.3.4 update fail I installed new battery and hooked to charger. Still get message of We recently tried to install a Ford Power-Up software update for your 2021 F-150 but were unsuccessful. We'll try the installation again at your next regularly scheduled update time. Ongoing updates like this help you enjoy the best possible version of your F-150.

 

They split the nav to save chips and a money grab.

I have a Lariat with built in navigation that will work as a real GPS after trial subscription. Like your 2020. Traditional navigation system of the past.

Most have lower trim use "connected navigation" that uses Internet for everything and will be a pointless moving map with no navigation ability without subscription.
Built in uses the connected for traffic data but the maps will still work without any future updates as far as I know. It might update with one of the OTA updates but I doubt it since they want subscription money.

For the folks struggling with 4.3.4….

I have a 2021 job 1 Powerboost. The update has failed 4 straight nights. Are you guys connecting the positive charger cable to the battery side of the sensor? Or to the opposite side of the sensor?

and are you guys attaching the negative termite of the charger to the ground screw? Or to the negative terminal of the battery?
