One XL corrupted software
It was working fine but outdated with maps and I hadn't updated for a number of years recently I decided to try and update so connected to computer followed instructions and it appeared to be updating then an error occurred and informed me that my device was too old and no longer supported, unfortunately what ever information it managed to download has rendered it useless.
I can turn it on and it will find present location but will either turn itself off and then restart or it will let me enter a destination but will not calculate it and then turn itself off.
had I known any of this prior to trying an update I wouldn't have bothered and left it at least being a functioning device.
Any help will be gratefully recieved.
