Patch and ROM files must be extracted from the ZIP downloads to the StarPatch program folder:
"\Program Files\PixSoft\StarPatch\". You can then use StarPatch to select the
patch file and
continue with an "Update Handset".
NOTE: April 2019 patch files can correct the output from older GPS units that report an incorrect date due to the GPS Week Number Roll Over on April 7, 2019. The GPS Setup patch for the 497/EP Autostar and Audiostar automatically include this feature. Otherwise you can select to include "Fix GPS Rollover Bug" if you have a telescope with built-in GPS.
