Most radars and GPSs have a way to connect an external
alarm. Suggest you read the manual for details.

Hello folks,

Tried to set up the alarms on a friend's Nonsuch 30 (he had never used
them)
and discovered we couldn't hear them due to high freq. hearing loss and
unit
being incased in a Navpod. Any way to hook up a louder alarm for the
cabin?

Thanks,
Bob
