Thread: Garmin devices preboot mode

It took me ages to get the 2597 into preboot so I thought I'd write a few notes.

The procedure is to turn it completely off with the USB lead out at either the GPS end, or the computer end (computer end is easier) - Then (with your left hand maybe) press Power-on and keep your fingers on the top Left simultaneously and keep them pressed. After a few seconds, you will see "System" scrolling a the top - At this point quickly plug in the USB lead with your spare hand but still keep your fingers on Power+TopLeft.

(For me, it seems to be easier to keep one end always plugged into the GPS back, and to plug the lead into the computer as you are holding down the buttons.)

Now the other important bit! As soon as the device has been recognised and you see it say "Loading" on the GPS at the top where it used to say "System", remove your fingers from the power button and top left, if you don't it will just reboot or put you into calibration mode - The timing is what it's all about.

I hope this is helpful to somebody! I couldn't find a single guide for the 2597 that explained all the bits together.
