Unit Check (Quick Check): GPS
WARNING: This page is about a different car, the 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.
If GPS indicates NG (ANT), then check the entire GPS antenna wire from the audio-navigation unit to the antenna only. If the wire is crushed or damaged, try a known-good antenna. If the diagnostic then reads OK, replace the original GPS antenna. If the diagnostic still reads NG (ANT), replace the audio-navigation unit. Select information to see the GPS satellite details.
