I thought I read on the board that Ford was readying an update to 3.4. I saw 1 post on it but nothing else. Is this true or is Ford jerking us again?
SYNC Region: NA
Navigation Variant: Nav
Manufacturer Year: Pre MY20
Install Type: OEM
Old SYNC Version: 3.0.20121
New SYNC Version: 3.4.23188
Do you have a error message, if so what is it?
N/A
Update Method: CyanLabs Syn3 Updater
Syn3 Updater Version: Current
Syn3 Updater Documentation Read: yes
Syn3 Updater Log File
N/A
I wouldn’t expect any additional updates to 3.0 or 3.4.
For vehicles that are factory 3.4 capable Ford has out a CSP for any vehicles that aren’t on 3.4.23188 yet and folks on Ford’s Sync site are seeing “update unavailable” if they don’t have NAV.
We’re five years past when the vehicles that were factory 3.4 compatible (like the 2019 Fusion) went in production and five years past when the last 3.0 vehicles (eg the Escape) ended production.
All of the development has moved on to Sync4
The last maps I expect to see for Sync 3.0 or 3.4 would be NA226, based on the fact that last year if you were past your free map period you could buy a 5 year extension (NA222 would be year 1), this year you can only buy single year.
The real question is: how are we supposed to know what Ford is doing? 
It’s not that important at the moment… Both Sync3 3.0 and 3.4 are just being eventually patched, so it does not matter if Ford creates new builds or not, since no new features will be released…
Ford has sent out customer service program 24B47 regarding Sync. Are they just updating to 23188 for those that have problems doing so?
Hard to say since it specifically says it is not an OTA update.
24B47 references SSM 52704:
SSM 52704 2019-2024 Various Vehicles - SYNC 3 - Accessory Protocol Interface Module (APIM) Programming Error - “INSTL_ERR12” Using FDRS Or Stuck On “Updating System Software” Or No Response From The Vehicle When Using The Universal USB Updater
Some 2019-2024 vehicles equipped with SYNC 3 may experience a programming Error - “INSTL_ERR12” while programming APIM using the Ford Diagnosis and Repair System (FDRS) or experience a frozen screen which says “updating system software” or no progress/response from module using the universal USB updater. This may be due to low memory in the APIM commonly occurring on software level NU5T-14G381-AB/BB . The current software level can be verified in the SYNC tab of Professional Technician System (PTS) or using the vehicle’s center display screen, Settings > General > About. To correct the condition, run the universal USB updater. If unsuccessful, using the latest software version of the FDRS scan tool, run the service function “APIM - Reset the Accessory Protocol Interface Module Application” and select “Clear All User Data” option. The center display screen will reboot. As soon as the vehicle’s center display screen displays the boot up logo, immediately reinsert the same universal serial bus (USB) drive that was utilized during the prior failed programming attempt. The vehicle’s center display screen should display “successful APIM update” when complete. If process does not complete as expected, retry no more than one time. If the concern persists, then raise a Technical Support Request for assistance. Do not replace the APIM prior to contacting Technical Support.
This is just an update to .23188 using FDRS and only applies to around 800k vehicles.
FDRS bypasses the Sync install process, clears the RW data partition, removes the old app files and copies the new ones in.
If the vehicle is a 3.4.x native vehicle and is already on .23188 the CSP doesn’t show in FordPass or the owner page.
