We fished Labor Day and I had trouble first thing in the morning obtaining satellites on my Garmin 498 GPS unit. Everything worked on the unit but the mapping. I turned it on and off several times and there was a red ? flashing on the screen/map where we used the unit the last time we were out.
Later in the day I turned the unit back off and on again and it worked. Has anyone else had trouble obtaining satellites or do you think the unit was frozen on the previous screen?
I have never had an issue before getting a satellite read.
I will try to trouble shoot it through Garmin to see what I can find out.
Should have gone to Garmin to start with. Anyway, good information if anybody else needs it or runs into the same problem.

There could be a few causes of the device not acquiring satellites. If the device has moved a large distance since the last time it has acquired satellites or has been turned off for longer than a few weeks or months, the device may not be able to acquire the satellites correctly.
The first troubleshooting step is to perform an AutoLocate procedure. This procedure will clear the device’s memory of previous satellite information, and try to download new information.
Note: This will not clear any user data like waypoints, routes, and tracks.
To perform the AutoLocate procedure, please follow these steps:
1.Start with the device powered OFF
2.Press and hold the Page button and Power ON the device
3.Continue to hold both the Page and Power button until the I Agree button is highlighted in the lower right corner of the screen
4.Press the Enter button
The device should now switch to the GPS satellite screen. Leave the device in clear view of the sky for at least 10-20 minutes to acquire satellites. If the device acquires the satellites before 20 minutes, the device can be used or powered off.
