Re: magellan roadmate 300 wont stay on

Mine is 2 years old and it just started doing the same thing! It would reset every few minutes. I see the same message about the maps being older, but I am not sure if that message is related to the problem or I just start paying attention.

It is the cigarette adapter, mine was doing the same thing until I bought a new adapter. When the old adapter plug to the GPS unit moved at all it would lose power.

My magellan roadmate 1200 will not turn on

make sure green light is on if using the car charger and let it plugged in for awhile, then hold the power button (up to ten seconds) until it starts..

if you tried charging it with both house charger and car charger and tried to start it like i explain and it still will not start, its most likely a bad power port which is very common with this model and many other magellan models.

How To Reset Your Magellan Maestro/Roadmate GPS Units

Factory Reset
Do not attempt to perform a factory reset on the Roadmate or Maestro GPS units by holding down both the "Reset" and "Power" buttons. This will cause the GPS unit to format its own hard drive. Doing so will erase all data, including the GPS software, from the unit.
  1. Locate the button marked "Reset" on the left, right or bottom of the unit.
  2. Using a thin object, such as a paper clip, depress the button for two to three seconds. The unit should reset.
  3. If the unit does not reset, immediately press the button again and hold it for up to 10 seconds.
If your Maestro GPS Touch Screen Doesn't work, try performing a Hardware Reset
  1. Remove the Magellan Maestro from the holding cradle.
  2. Hold down the "Power" button on the right side of the device, until the unit powers on.
  3. Straighten the end of a paper clip. Place the paper clip in the reset hole, located on the left side of the GPS unit. Hold down the "Reset" button for 10 seconds. Remove the paper clip.
  4. Turn the Magellan Maestro unit off by holding down the "Power" button. Turn the unit back on again. The device is now reset.

If your Roadmate GPS is locked up, try performing a Hardware Reset
  1. On the RoadMate, press + + - - + -
  2. The "hidden menu" will appear.
  3. From there, you can access the shell and perform a hard reset.

My magellan roadmate 1212 will not stay on unless plugged into

if its not charging the battery, the meter will say full even though the battery is dead..its a very common problem with alot of gps with the usb as a charging port. my solution is if this is still under warranty, i would send it back to magellan or where ever you bought it, because sooner or later the usb port is going to totally fail and wont even start up if plugged in and your going to be left with an expensive paper weight.

Magellan Roadmate 760

The weakness of the 760 is the cradle. Is the power wire or the cradle loose or wiggles? You may need to buy a new cradle if that is the case. They are expensive. I soldered my power wire right into the cradle and it worked fine.

Magellan roadmate 300 speaker stopped working

I have an extra unit. I don't have the magellan road mate manager. I would be willing to trade the whole unit if you could get me the magellan road mate manager cd. I hear there is another one that comes with it that would be great to have also. I have tried everything to get these cds but to no avail. comment here or email me at if you are willing to do this.

Magellan 2200T won't completely boot up

Reset unit, and then turn off, but hold power button for at least 10 seconds, then power back on, and when ever you turn off unit, hold power button for 10 seconds, had the same problem with mine, this solved it, it seems that just turning off the unit till screen shuts down puts it in a sleep mode. Hope this solves your problem.

Magellan roadmate 300 wont turn on!

I think the problem is with the internal power jack which tends to break. the part is MG361213 and is available at You have to take the Unit apart and remove the old jack and resolder the new one which is a three pin unit.

Good Luck

Language on Magellan Roadmate 300

You'll have to obtain a copy of the Magellan Roadmate manager disks, load them into your computer, connect the GPS to your computer using the USB cable and the use the "Roadmate Manger settings" to change the language.
