I have a 2018 Ford F-150 that originally had a 4-inch screen with Sync 3 version 2.3.18095. I swapped out the screen only with an 8-inch screen. The Sync 3 version is still on the 4inch screen software where it only shows in the small corner of the 8inch screen and doesn’t have touchscreen or CarPlay etc.
I’ve seen two or three forums with similar scenarios on this site, but there was missing info between private messages and such. Unfortunately I only have access to a mac. I have the proper USB, I have a general idea of the file structure, but just getting errors such as lst_err05 when following the manual method on this site. I imagine I need to do something different in my scenario due to the 4 to 8 inch swap.
Is this do-able?
SYNC Region: NA
Navigation Variant: Non Nav
Manufacturer Year: Pre MY20
Install Type: OEM
Old SYNC Version: 2.3.18095
New SYNC Version: 3.4
Do you have a error message, if so what is it?
The error you are getting is: “LST_ERR05 – Error is LST_PKG_FILE_NOT_FOUND”
It seems your MAC has uncompressed the files, check the extensions of the files under the SyncMyRide folder, they are .tar, not tar.gz as they should be.
Also, notice that the .LST files are referencing to tar.gz files, not .tar.
So copy the files again and make sure the computer does not uncompress them.
That’s why you are getting an LST_ERR05 error, since the LST files are referencing non-existent files.
