I just read on a boating forum that there is another satellite, PRN-133 available for WAAS. Don't know enough about this stuff to understand if it will increase accuracy or if its just a redundant one, but more is probably better

There are a few instances in which you may want to perform a master reset on your GPSMAP 60, 60C, 60CS, 60Cx, 60CSx, or GPS 60, such as:
All settings, user data*, and satellite data may be erased when resetting the GPS. User data can be backed up to the computer, therefore refer to the FAQ article "How do I back up user data from my GPS/GPSMAP 60-series?" before performing the reset.
- not receiving a satellite signal
- want to restore the factory default settings
- not functioning properly
To perform a master reset:
The GPSMAP 60, 60C, 60CS, 60Cx 60CSx, or GPS 60 is now reset. You will want to leave the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite data.
- Ensure the device is powered off
- Press and hold Page, Enter and Power simultaneously
- Release on the buttons once the Do you really want to erase all user data? message appears
- Select Yes
*User data consists of waypoints, routes, tracks, and geocaches
