Please Help - Ford Focus 2013 Sat Nav Issue

[SJG1990]

Hi guys 

I have indeed used the search feature but just cannot get passed the point I am at now - would really appreciate some words of wisdom

I've had no sat nav for months now - GPS with a line through it , it has been thinking I am located somewhere else (hours away from my actual location.

Anyway, I bought a Fakra GPS ANTENNA off eBay and got as far as connecting it to the back of the screen but ....no fix !! I dont understand what I have done wrong 😞 anyway advice appreciated

Is it sync 2? Could it be maps itself, like corrupted sd card?
