A "GPS ANTENNA ERROR" message indicates that the NAV unit cannot detect the GPS antenna (Discovery on roof, Freelander in base of
radio antenna). Investigation of cable connections or cable damage will determine the cause.
If the message "GPS ANTENNA ERROR" appears, investigate the cable connections and continuity to ensure the NAV computer can see the
satellite GPS signals.
Watch the "ALM" number. Once it has reached a number of 28, calibration can continue.
Determine if "ALM=28" appears in the lower right of the NAV screen.
If "ALM=28" does NOT appear, allow the car to download the Almanac from the satellites until "ALM=28" appears.
