Garmin C550 Map View Switches to Entire U.S.

[+david.travis]

I have a Garmin C550. Every now and then, while we are driving, the map view will switch from showing the highway on which we are driving to a view of the entire United States with our "vehicle" icon showing our position. Then, after about 15 seconds, the view will return to the normal map view. I reloaded the unit software, but it still does this. Any idea as to what may be causing this? Is this considered normal?

 

Thanks in advance for your help.

Finally got it fixed. I reset the GPSr, cleared all my user settings, reinstalled the software and re-installed the City Navigator 2008 update. And, that completely cleared the problem!
