I have a DR750LW and I have a problem with the onscreen Icons. When I touch an icon on the dashcam screen they all disappear. If I then touch the screen they all come back which means I cannot use any of the Icons for the purpose for which they were intended. For example no playback is available on screen and I can't alter the Settings therefore in order to review any recorded footage I have to remove the SD Card and play it through my Desktop. The cameras are both working fine and recording constantly without problem but I would like to get my onscreen icons working properly again - anyone had similar problems or have any ideas to resolve this issue. The SD card is new and the Firmware has been fully updated.
