Matt,
Do you suggest to touch the Ident Button to replace it with a new Data Bar Field?
This is the procedure described at page 42 in the G3X Touch Pilot's Guide:
Changing the information shown in the Data Bar fields:
1) Press the MENU Key twice.
2) Touch Setup > Data Bar > Data Fields.
3) Touch one of the Data Bar fields.
4) Touch a new data field from the list.
