Original TomTom touch screen calibration

My original TomTom's touch screen calibration has gone bad.  I cannot 'touch' the letters at the far right during data entry because the entire data input screen's touch mapping has shifted right by about half a column.  The touchscreen mapping for the other functions is still good.  Has TomTom forgotten to retain compatibility with their original device?

Re: Original TomTom touch screen calibration

The sensing area for all functions except typing is fairly large which is why they don't seem affected.

You can try to manually calibrate the screen, some people have had some success with it.

The actual problem is that the digitizer is failing.

Re: Original TomTom touch screen calibration

Try cleanning around the edges of the screen with a business card between the bezel and the screen. Bits of dirt can cause problems. You may well have more serious problems (see Traylaw's post), but try this simple non-invasive step first.

Re: Original TomTom touch screen calibration

Thanks.  Did calibration.  Five minutes of trial and error and my TomTom Go is working perfectly.  Nothing dying that I can see:smileyhappy:  Not to fret, we own four TomTom's in this household.  Good to know there are 'repairable' as the age gracefully.

Re: Original TomTom touch screen calibration

Glad the calibration worked for you.

 

On a different subject: Be sure to backup you gps's. We recommend using windows explorer. Note that each gps should be backed up separately since the maps are not interchangable between different gps.

See this link for the procedure.

Re: Original TomTom touch screen calibration

I have the original TomTom Go 720 purchased in April 2008. I purchased also in April 2011 6 Italian map updates. After last update the  touch screen calibration has gone bad.  I cannot 'touch' the icons at the top of the screen during data entry. If I tip an icon at the bottom of the touchscreen I display the correct content of the icon tipped. But, if I tip an icon at the top of the screen then I always display the icon immediately below. Its' a particular case because the entire data input screen's touch mapping has not entirely shifted down.

It's incredible that after purchasing an official map from TomTom web site now it's impossible to use the entire application. I have to buy another TomTom since repair costs are 105 eur.

Any advice is welcomed
