Compass 2015 GPS
 

I have a 2015 Compass Limited 4X4, since new I have problem with the GPS, only some time working, the other time just can't locate where I am but only showing the map at near by such as 2-3 street next with wrong direction, or next suburb. Dealer changed the antenna than changed the whole Radio unit but the problem still there. Did any Compass driver experience the same? or if any Compass Driver can tell me how to fix it!

What headunit is it? It should have a identifying name on the bottom right corner.
