X107CDF that comes on by itself and won't shut off (drains battery)

I have two X107CDF units in our Triton boat. One is in the dash and the other up front by the trolling motor. The one in the dash comes on by itself and beeps and the screen flashes. You cannot turn the unit off with just the power switch. I have to press Menu and Pwr together (???) but it is only a short fix as the unit will come on again by itself. I adjusted the ASP to High. I also have had a dead engine battery. Do you have a suggestion?

When I power up all I get is the Magellan Triton screen. My pc does not recognise the device also

1.Ok, if you have tried the manual update and it won't work then the thing to do is download this file:

To download the file just use your mouse to click on the link, which is the underlined and blue highlighted section of text just above.

2.And then connect your GPS your computer and start it in the developers mode - which should make it connect to your computer as a USB driver.

To start your GPS in developer mode ,simultaneously press and hold the POWER - LIGHT - UP ARROW buttons as you start the GPS.
Want to get out of this mode, you can reboot the unit by simultaneously pressing and holding the POWER - SELECT - ESC buttons or just take out one of the batteries.

3.Next unzip the T500TFAT2.ZIP file to a directory on your hard drive. Once you have that unzipped go to "My Computer" and access the TFAT directory on your Triton and erase all of the files on it. Then copy all of the files from the T500TFAT2 file that I sent you. Once you have the new files in place then disconnect your Triton from the computer and reboot it and see if it works.

If you need further assistance please feel free to contact me.

Magellan gps Triton 300 series Jamed up; Reads when turned on ; Internal Error Your Triton has encountered an unexpected error and must shut down. Please wait while your data is saved.

The problem with your magellan triton is that there is a file missing in the support file that allows the triton come on properly hereby leading it to jam.
The solution is for you to get your triton connected to a computer, then you back up the software on the computer, format the triton then you restore the software and maps on the triton. Then your triton will be in good condition once again.
Hope this information helped.

My magellan triton 500 was left on all night. After replacing the batteries it only comes to the first screen, fills the progress bar and freezes, won't shut off. I've tried removing the sd card - no...

When the batteries died .. a problem was created with the internal memory files. They have been corrupted. It is too complicated to fix yourself. If the is out of warranty, the Jungle Ghost at has a repair service. He works for Magellan Distributors to fix their units.

When turned on the triton 400 gps will read; internal error.... your triton has encountered an unexpected error and must shut down....please wait while your data is saved.

This problem is caused by a corrupted software file on the internal memory. The chip has to be reflashed. If under warranty return the unit to Magellan.

When I power up my Triton 400 an Internal Error message window shows up and then the unit shuts down after a few seconds. It fails repeatedly. Is there something I can do to be able to use my GPS again ?

Hello :

First try new batteries . If that didn't work , then I recommend you to reset your Triton . Resetting can solve errors and faults that occurs in your device .

Try this for resetting :

1:Using the stylus, tap "Main Menu" and select "View."
2:Tap "Settings," and select "Restore Factory Settings." You will be given the option to confirm this action. Be sure that you want to reset to the settings that the GPS was built with. This action is irreversible.
3:Tap "Confirm," and the unit will begin to reset.

For that you need a thin object (such as a paper clip)

Don't use this method on other Magellan models .

Unit powers itself down

does it do this when on battery mode?
or when its plugged in?
i found they do tend to drain quicker the older it gets and that just because of a week internal battery.. i just leave mine plugged in to the cig lighter in my car and i dont have that problem but if you have to use battery power it will drain fast no real fix unless you get a new internal battery and its much easier to just leave it plugged in.
