TomTom screen calibration fix


At first I thought that the touchscreen on my GO 720 had died, but then I found that the vertical calibration had somehow gotten messed up: when I tapped in the top half of the screen I was "clicking" in the bottom half (and therefore I couldn't "click" in the top half at all).

I was able to correct the problem using the technique described here.

720 Re-cal

There must be a calibration quirk in the 720 units. I see a lot of them with this issue, but very few with the other models. I had to do a re-cal on my 720 last month, but with a lot simpler technique.
