I have a Pioneer AVIC-X920bt and I´m getting problems while I try navigate in GPS... It does not connect to satellite If I enter in System to verify the sinal I get: GPS antenna problem detected. Contact dealer or service Center. If I enter in 3D calibration I get: sensor initializing... I had read some posts and they said to do a hard reset and maybe the problem would resolve. But, how to do it? I removed the baterry cables for 15 minuts and it appears that did not reseted, because the colors of the device did not change. So, how to reset the device? How to be sure the device was reset
