We have a go710 that's been happily running navcore 9.43 for a while, until a few days ago the SDcard in it died.
No problem i thought. Just extract the backup i took of the card when it was originally configured to a new card.
New card inserted and everything boots as normal but the "Waiting for a valid GPS signal..." never goes away.
GPS status screen shows 9 satellites in view but they're all greyed out. The time next to the activity disc is correct so i'm assuming it's pulling this from the satellite data? Reset via holding the power button and the hard reset button but no difference.
Edit: Have tried with empty ephemeris folder and with new files from quickfix.
Any ideas?
