The magellan skyblazer has been in storage since last fall,2007. after fresh batteries, and turning on, the gps can't seem to find satelites,or its position.it was working just fine before storage in the fall. some fellow pilots told me that, some of the satelites have been turned off, and the unit may be obsolete. i find that hard to believe, but i guess its possible. help....ken

SOURCE: Problem with Magellan GPS 315

I own Two Magellan 315. They both have failed in exactly the same way as yours, will not lock on too a satillite. I have concluded that this is their design life and that is the end. I did post one to the Magillan repair centre in France but that disappeared. I have replaced the two of them from EBay and will see how I get on with those

SOURCE: Is it possible to track a stolen GPS with the serial number?

Garmin has a large hard drive with all the points of interest inside the device.
All the device does is read the GPS coordinates that are broadcasted by the GPS satellites and processes data based on what it receives. It doesn't need to send any information to a central server.
If GPS was able to communicate two ways, there wouldn't be a need to purchase map upgrades for new roads, points of interest, etc...
I just got my Garmin stolen within the past 23 hours, and as much as I wish there was a way, there isn't...

A Garmin Nuvi 1300 that won't start, freezes on 'loading maps,' or is acting erratically is symptomatic of having corrupt firmware.

To correct this, I recommend backing up your favorites, clearing all user data, and if it still is stuck, then updating your Nuvi firmware.

Follow these three steps to take to get your Garmin Nuvi 1300 running like new:

1. Back up your Favorites.
2. Perform a Hard Reset.
3. Download and then run Garmin WebUpdater to replace its firmware / system software.
