SYNC 3 Navigation Instability issues


Recommended Posts

Hi All,

I recently got a Fusion 2017 w the SYNC 3 Navigation option and noticed several stability issues. I was wondering how to tackle these, as they happen during driving. Here's a short list:

1. When going through an area with no GPS coverage (enclosed tunnel or bridge) - the GPS loses fix completely. Once it loses fix it takes over 30 minuted to recover and it seems like at some point it gets very delayed GPS fix information. For all intents and purposes - once I go through the tunnel, navigation is useless.

2. When canceling the navigation while having a phone conversation - the audio navigation instructions continue, until the call is disconnected. So the screen reports no active route - while the system continues to guide you audibly. Very weird.

 

I have the latest revision according to Ford's website.

 

Any suggestions?

 

Thanks
