Re: Explorist 300 problem

Did the software come with your purchase? If so, you can clear the nand flash and re-load the software. If you have the software let me know and I'll tell you how to do it. -Daniel

Magellan Roadmate 1412 won't track satellites

It might mean that the signal is disrupted. Might be a software glitch. Try going outside, get a clear view of the sky. Then reboot/reset the unit. Hold the switch to the reset position or off position for 10 seconds, it will shut off. then switch it back on. It should reacquire a signal within 2-5 minutes, then it will fix on your position. If that doesn't work, try updating your software. Call Magellan Tech Support for instructions.

My explorist Gc unit...on start up is looking for an active tracking file which is missing. I have a copy on my desktop. How can I get it back into the unit?

You can download the US basemap for the 500 at
Then copy it in the directory "background maps" in the SD card of your 500, by using a SD card reader/writer.
Insert the SD card in your 500 and connect it to your PC; then turn it on;it will turn on regularly, because the basemap in the card will be detected; turn it to USB file transfer mode, and copy the basemap from the SD card to the directory "background maps" of the 500.
If you already have the file ..just rename it like I said ..and copy it ..using the sd card in the reader...Than if it is not functional ..just reset it ..and reload the file the proper way by reloading maps..

Hi Guys: On turning on my explorist 400 a message appears. UNIT CURRENTLEY CONTAINS NO MAPS! INITIATING MAP UPLOAD This message wont go away, and all buttons refuse to work. The only way I can turn it off...

Jeff, I had the same problem with my explorist 500. Your unit lost the "BASEMAP.MGI " file. You will need to get a copy of that file. Then install it.
Try this site
(I would recomend all explorist GPS owners copy and save that file and store it in a safe place. I have mine on a thumb drive).

Loading Topo maps...210 says invalid base map??

To get the base map and to get your unit functioning again:
Install the firmware again:

Go to:

Or, if this doesn´t work, go to, click on"support", click on "legacy products" (left) and click on "eXplorist210 Europe" (do NOT click on "eXplorist 210 North America")

On this page click under Updates/Upgrades on "version 2.57", and follow the instructions. You will have to register your GPS, register it under a European country.

After you have installed the firmware you will have the basemap and some new windows on the GPS. Good luck and enjoy!

Button does not work

if you don't mind taking it apart, carefully unscrew the case and seperate the two halfs (be carefull not to break any of the wires or ribbon connections) , pull off the rubber pad with the buttons, and clean the contacts on the circuit board (you could use alcohol, or I use model railroad track cleaner that you can get at a hobby shop)

Unit Freezes Up

Try turning off the WAAS function to see if that makes a difference.  If it's already off, try turning it on.  It's either a software/memory problem, or there's a short in the antenna. There is no update available for that unit.

Explorist 300

since the unit doesn't have a base map it needs to be loaded with the base map so send it for a service so that the base map could be added.
