Re: Roadmate 300 GPS

I had the same problem and solved it by plugging the USB cable into the device, powered it up, went into the "Magellan Roadmate Manager", clicked on "Settings" and then clicked on "Voice Options" and my sound came back.

Won't say that it will work for you, but it did for me. Worth a try!

No maps found!!

Hi - I have the same model GPS but I've been unable to locate a copy of the CDs and I'd love to get a copy of them - would that be possible? My email address is

As far as re-installing he maps, here's what I've found. I think this might help:
Locate the files that are loaded on the computer.Magellan Roadmate Manager example: C:\Program Files\Magellan\Magellan RoadMate Manager NA\Map\Basemaps
Copy all files. Make sure your Roadmate is connected and click on Example E:/Removable Disk and paste them with other files. It takes a few seconds to 1 minute to transfer the 25.5 mb file so don't unplug it until it is finished.

Magellan Roadmate 300 no sound

A single IC chip controls both the sound and touchscreen. More then likely, something has malfunctioned with that IC since neither are working. You should just get a new one.
