Question about Magellan eXplorist 400 GPS Receiver

2 Answers

No communication with computer

When I connected my Magellan Explorist 400 to the computer via the usb port, Windows xp does not recognize it. It recognizes an unknown device. I have attempted connecting to to various usb ports on my computer with the same results. This makes it impossible to upgrade the firmware or transfer any maps directly to the gps. Fortunately, I can transfer maps to the sd memory card, but that is a limited solution. Any ideas?

    Thank you for your reply. Magellan does not appear to offer a usb driver for Windows XP. But I did accidentally discover that I had the cord attached to my gps incorrectly. The tab goes at the top rather than at the bottom where the slot is. Once I attached the cord correctly, my computer and gps communicated flawlessly.

    I bought a new 500LE explorist with a hp pavillion and it never recognized the drive unless there was a blue moon or george bush was right about something.

    Finally it seemed to always work when the backlight was on low... weird!

    I bought my explorist 400 in ebay and came with a copy, not original instalation CD When instaling in my PC with windows XP a got a warning sign that said did not passed Windows logo testing. I don't nkow where to download the driver that work. Magellan doesn't have it available to sell, download etc. I have an original disk mapsend can not use because can conect my GPS and PC.

    I would ignore the warning message that the software has not passed the Windows logo testing. In my experience, I have not had any problems running software which has not passed Windows certification. My personal opinion is that Microsoft uses that as a scare tactic to force people to buy only Microsoft products.

    Go ahead and install the software. I did and have had no problems with it.

    I had the same problem. Called support and stayed for 40 minutes. The so called 'tech' determined that the usb cable must be bad. He's going to send me another one. Since we had bought 200 of those units, I tried to use another cable but with the same result.
    Guess what, I read this post and switched the cable around (tab up instead of down) and it started working. So much for tech support!

I would try downloading the USB driver from magellan (if they offer it).  You may also be able to get the driver from C-Map USA as the do the map software for magellan.

Where do i plug the charger into my magellan? seems like there is smothing missing on the back of the unit. unit is magellan explprist 400

  • It may be a little confusing. You actually plug the USB computer cord into the back of your GPS (see diagram) and then plug the AC power cord into the end of the USB cord (that would normally go into a USB port on your computer.) In effect two wires connected together. Then plug the AC adapter into your outlet.

  • Hope this helps.

My Explorist 210 does not connect with any computer. What can I do.

What is happening is your computers are not recognizing your unit. Means you have to update unit via the registered site for updates.

first Perform a hardware reset to return the minor settings of the GPS to the original condition. Press the small "Reset" button on the side of the unit for several seconds until it powers off and powers back on.

If that doesn't solve the problem, then it means you will have to perform a firmware upgrade to put the GPS back in order.

Download and install the Content Manager software available for free from the Magellan support website. Connect your GPS to your computer with a USB cable, and the software will automatically search for firmware updates for your GPS.

Here is support to copy and paste in your browser for Magellan. Thanks Mike

Laptop does not recognize magellan 860t when connected to usb port Magellan POI file editor issues message "no unit detected".

assuming your using a known good usb cable, you need to use windows XP sp2 or greater to install any magellan. if you are using that os or greater, try a different usb port.

if that fails, restart the computer and try again.

you can also try and reset the 860 using the reset on the top and see if that will help.

if none of those work, turn the reset button to the off position till the 860 goes off then plug in the usb cable and restart the 860.

if your not using windows XP sp2 or greater, hopefully you have a friend that does.

Computer does not recognize it

assuming your using a windows xp or 2000 os, try another cable if you have one..turn the gps off, plug in the usb cord and restart the gps. if that fails, if the cable is connected to a port on the front of the computer,move the usb cable to a rear port on the computer and try the previous way i just explained.

if those fail, disconnect all usb devises connected to the pc and restart the computer and try again. (always use a rear port on the pc if you can)

good luck

NMEA communication does not work ( but file transfer is OK)

Try rebooting windows, with gps off connect the cable to gps.

Go out side get a good gps signals on nav menu.

Set the gps communications menu to , nmea, 2.1

Plug the device into a good usb port.

If you look under modems, in control panel you should see a new modem called explorist xxx

If you look at the properties for that you can see its com port number.

I just tried this program

and it views nmea from the explorist, just set the com port to the one in the explorist modem .
