After getting a new APIM and having it flashed to MFT 2.11 the GPS is pretty much unusable. The car skips along the map and many times it just hangs. Making guidance a joke because you are past the road by the time it catches up. I've done a factory reset but that did no good. I also monitored the GPS from the diagnositcs menu and that seems to be reporting correctly. Anyone else have GPS issues like this or is yours smooth and accurate? The previous gen Ford NAV in my SHO and 2010 GT500 was excellent. It looks the same as this but with the old GUI.
