What is fixing new firmware? It writes that it fixes some mistakes in Panama or are it Panorama modes? After installing, I noticed that the compass is now calibrated differently and now I do not have more buzz in the controller and the need for the road by calibrating the controller. I noticed, however, that he returned me to the CE mode instead of the hacked FCC mode. The return back to the hacked FCC mode was difficult because did not want to accept the OK button. How do you have experience with this firmware?
