After backing up the 'DataFlash' folder, when I now power up the F350 I get the screen 'Calibrate' display and can't get out of it, except by frantic power-off/on with screen tap actions to get to the 'Navigate' screen. Can anyone suggest what's wrong and how to get out of it ? Thanks.

Couldn't you just calibrate it? If you do, does the screen go away?

No matter how many times I tap on screen to 'calibrate' it, the screen does not change. The calibrate cross steps round the screen without end. It's stuck permanently on calibrate display.

I hear you. If you're using your finger to calibrate it, try using a stylus instead. Your finger might be too fat LOL.

What was the dataflash folder?

Grateful thanks ! I have previously used the stylus but never actually tapped precisely on the X and therefore never followed it around the screen (twice, just now).
Now I can get on with trying to install IGo without this complication.
Thanks again Chas.

One of the three folders shown under 'WindowsCE' when the F350 is connected by USB. It contains 'Maps' and 'Navigator' and is what I assumed is a critical internal folder to the F350.

On Binatones you don't need to touch the internal memory, you can run applications directly from the SD card.
