Hi I have recently updated the TomTom firmware to 6.52. It asked me to remove the device and restart, which I did and it worked fine. I Then connected it back to copy the Speed Cam POI on it and after I disconnected/restarted TomTom, it shows a blank screen. It turns on with splash screen coming and then turning to a black screen, it doesn't respond then, I tried to leave it for sometime but doesn't work.
Does it need to be kept running for some time to allow POIs to be updated on the map? or I have lost it
