Calibrate Screen TomTom Truck
I have a Tomtom Truck Pro Model 4CR52.
The touchscreen was malfunctioning so I was forced to trade the touchscreen for a new one, fortunately a repair shop was abre to swap it successfully but now the new touchscreen it not calibrated, so some clicks on the screen are impossible to be done. From what I've seen arround forums, you could calibrate the screen by adding a cal.txt to root folder in order for it to read but I believe this model has internal storage only. On the botton it has 2 slots, one for 3G card and another for a Micro SD. I´ve tried to add a microSD formatted as FAT32 with only 2 files in it, cal.txt and calib.txt and as I start the GPS, if I click the powet button uppon the chim it shows some stats, some of then where the touchscreen previous calibration but even changing only a value by 10 from the initial calibration and putting it on the MicroSD has no influence whatsoever.
Is there any tool to mount the internal memory of the device or to upload just the cal.txt file to the device in order to make it work properly again?
