Navigation Issues Sync 3


Recommended Posts

Hi all,I'm new to the forum. A while ago, I switched the sync2 to sync3.

I installed it with an aftermarket Fakra GPS antenna, not the Original one.

Once in a while, the sync3 is struggling with the map loading, ans then I get the 

navigation error.

I've read and heard several times now, that the antenna is the culprit.

Is that so??

I've read that the antenna could be the issue... I don't have my 2013 to test it anymore...

my guess is the cheep ones, or the ones you would think as for the Fords might be the bad ones to have...

 

with the car on, and Audio on

press the Eject and Right Seek (maybe Left one?) together and it will bring to to a special menu, it will start testing with the long tones....

 

In there is a setting that will put a new button (Icon on menu) to clear the fault the nav makes.  Once you set it up, you go to the icons and press it and the Nav comes back.

I'm having same issue and have tried 2 different (albeit cheaper) antenna from Amazon, with similar results. I have a third one coming that looks more like the ones the infotainment sites sell.

 

What brand(s) worked for you/others? 

 

I've done this work around for now to dismiss the error but wife isn't please with that popping up.
