Original APIM Sync 3 As-Built for Focus ST

Focus ST APIM Sync 3 (factory)

Hi, I have a 2014 Focus ST with Sync 1 with Swap for Sync 3. Everything is fine except my GPS doesn’t give me the correct location and I have to configure, according to a Cyanlabs post, the As-Built of an original 2016/17 Focus ST with factory Sync 3…

Problem with GPS Position in SYNC3 Navigation

The nav accuracy is way off, it should be sub 10 meters. The time to first fix is too long. All of this is independent of the Vehicle Settings, this is an indication that the antenna is weak. The fact that the GPS is wandering, and the location fix is not accurate would bear this out. Just because the APIM can see the satellite does not mean the signal is good enough to decode the GPS positional data. Keep in mind the nav and satellite receiver are not controlled by Sync 3 and are independent su…

If anyone could do me the favor of donating me the asbuilt file, thanks

I have already configured As-Built in DE02/7D0-03-01: x*XX-XXXX-XXXX

• 1=Instrument Panel (IP) Mount (Non-Heated Windscreen)

However, the problem persists and, as I read in the thread in the previous link, the current configuration for my As-Built is not correct because it comes from another donor APIM.

You’re in USA?

also post the asBuilt file to make it easier for people that might want to help you update your current one

Here’s APIM asBuilt from ford focus ST from 2014 with Navigation.

Module=7D0 (APIM - Accessory Protocol Interface Module (SYNC))

7D0-01-01 A128 E103 C046 
7D0-01-02 0418 5300 044D 
7D0-02-01 5553 0006 40C8 
7D0-02-02 C200 2000 00BD 
7D0-02-03 0000 DC
7D0-03-01 0252 3900 0068 
7D0-04-01 0103 0200 00E2 
7D0-04-02 0000 DD

Try to copy those blocks from 7D0-01 to 7D0-04 and see if it improves navigation for you. If you get any DTCs let me know we can try to keep correcting the asBuilt until no dtcs appear.

BTW is your gps an aftermarket or it’s OEM antenna?

Is for Sync 3?

[derolk (7D0-01-01)]

Focus ST with Sync 2 + Nav, but from what I see, it closely matches sync 3 so it’s a good start because Ford focus from 2014 didn’t have sync 3 by default.

You can use it as a foundation and then customise more. Main thing is for you to safely go from sync1 4’’ to 8’’ config and then customise more until you meet sync 3.4 specs.
Its going to be a trial and error thing because you made a huge upgrade

[derolk (7D0-01-01)]

Also asBuilt is usually not about Sync but your car’s actual capabilities

[Espeacke]

*the GPS is aftermarket…

From what I see

in the post of the similar problem thconfiguration is of the bit
7D0-07-01 To 7D0-08-02

I have loaded the configuration that you sent me and the result has been the same

Alright I will DM you so we can coordinate better

@Espeacke

Is this APIM been modded? The nav and radio screens are reversed.

[Espeacke]

No, It looks upside down just because of the navigation error message, when I start moving the map is placed as it should be in the place you mentioned.

[Espeacke]

It’s worth mentioning that the first few meters it works in the correct location, but after one or two blocks the GPS doesn’t give the exact location, and the same thing happens with CarPlay.

[derolk (7D0-01-01)]

For future reference, the problem was fixed by customising asBuilt to match the car, an 8 inch APIM and Sync 3.4 together.

The settings at 7D0-05-xx thru 7D0-07-xx are vehicle specific and must be correct for the NAV to function properly. They would not have been from Sync 2 as they do not exist for that NAV system.
