No GPS signal on Go 740 Live after recent update
I updated my device just over a week ago after an email from TT telling me to ignore any message that my device wouldn't update and continue. Since then my device will not receive a valid GPS signal. I've left it on all day and tried multiple resets, with no joy. When I do a reset, the device switches back on and displays a black screen with writing that details all of the sat navs information. I have left it on this screen for hours, but nothing happens, so I switch it on and I am back to square one.
Please help, desperately need my sat nav on a daily basis..
