SD Card for magellan 300,Can I use any card on it?
The Magellan Roadmate 300 and 300R both require preloaded map data to be supplied from an SD card. You can't just pop any card into the slot and get it working. It requires a card of 2GB or less loaded with Magellan mapping software. Magellan provides nationwide maps and regional maps. The 300R was a regional unit while the 300 included a national basemap.
If you have a model 300, you can still use the highway basemap to get routing from city to city but you will not have detailed address routing at the residential street level unless you insert an SD card with Magellan software. If you have a 300R model, the unit will be useless without the Magellan software on an SD card.
Magellan doesn't seem to offer much software support for this unit any more and the maps are difficult to find.

My new Magellan Roadmate 300
You have to have the two cds that come with the unit to download onto your computer. If you can find these then there is a sd slot on the bottom of the unit covered by a small rubber cap .The sd cards must be the ones that will work on a magallen .You can go to magallens internet site and get a list of the ones that will work.

Does not power up.
Normally on these devices there is asystem reset that can be accomplished by pressing and holding in the reset button for 4 minutes and if this is a newer device than they have a internal reset feature that requires you to press in the reset for 3 minutes and than leaving the device unplugged over night or 4 to 6 hours and if this still does not work there is a small fuse that is on the main board that will fail and needs to be relpaced
If you feel confident about opening the unit up, radio shack sells the fuse that will fit this device.
But if the unit is still under warranty i would use the warranty and have the unit serviced and they will also provide you with any updates that are available if any ok?
I hope that this has been very helpful for you
Best regards michael
