I have read about half of this entire forum by now, as wel as TomTom's own and Navi Total's, so far without finding an answer.
My Go Classic is still working after 10 years, but it now seems to have digitizer trouble, as the leftmost column of characters can no longer be reached. I played around with the keyboard options large/small and QWERTY/ABCD. No luck.
I have tried the non-invasive operation, removing bits of dirt around the edges. No luck.
I placed a cal.txt file in the root of the SD card with modified settings. I checked the HW settings: the cal.txt is disregarded.
Now I wonder: is there a minimum requirement in bootloader and/or navcore for this calibration file to work? Or is it purely hardware dependent?
