I thought I would submit some feedback from trying to use the two suggestions to re-calibrate the touch screen on my GO530 on this thread, firstly, I failed miserably with the first which was the 9.510 calib way which would appear to be a navcore that you use an SD card to "install" in your device.
These are the instructions contained in the text file named "9.510 calib", they did not appear to be accurate in my experience, assuming I did it right?
9.510 calib.
"After Install go to the Skin Chooser (menu 4 of 4)"
I WENT TO MENU 4 OF 4 AND FOUND AN ICON ENTITLED "Calibr" (something like that) NOT SKIN CHOOSER?
"Click on it and you got the calibration screen and start calibration."
CLICKING ON THE CALIBR ICON TAKES YOU TO THE CALIBRATION SCREEN.
"The next screen Dubbel click on the 25."
I DID NOT GET ANOTHER SCREEN WITH A 25 ON IT TO DOUBLE CLICK?
"The device restart and hopefully the screen is alright (after the calibration)."
AFTER CLICKING ON THE 5 CROSSHAIRS TO CALIBRATE THE DEVICE RESTARTED.
"You can go to the Skin Chooser and choose another emulation."
I BELIEVE THIS INSTRUCTION REFERS TO AN APP ENTITLED DSA-EMulation THAT YOU CAN START IN THE ROOT OF THE SD CARD WHICH ENABLES YOU TO CHANGE THE STYLE OF THE INTERFACE FOR THE NAVCORE.
"Calibration is no more possible. If you want to calibration again you"
have to install the 9.510 calib again."
I RE-INSTALLED THE NAVCORE BY EJECTING THE SD CARD, STARTING THE DEVICE, SHUTTING IT OFF AND PUTTING THE SD CARD BACK IN.
I tried this several times but the only result I achieved was that the calibration was much worse in the opposite direction, so didn't work for me.
I will concede that my knowledge of satnavs is limited so I could have got it all wrong!?
I did get my device's touchscreen calibrated well enough using the second method at this link from "biggerdave" post on this thread.
http://www.navitotal.com/viewtopic.php?f=80&t=10957I followed these instructions and once I realised that you need to call the text file that goes in the root of your device "cal" not "cal.txt" I started to get somewhere and after some considerable amount of time calibrated my screen well enough to be usable.
I was lucky that the left/right and not the up/down axis was out of sink!
Hopefully this feedback might be of help to someone or someone might put me wright if I lost the plot with the first option?
Thank you to "holyhead and "biggerdave" for your input.
