Dashboard Fault

Hi I was wondering if anyone has any ideas. I have a Almera Tino S 2005. When I am driving it and it warms up the dashboard keep resetting when I indicate. It does not effect the outside lights or indicators but the speedometer and petrol gauges ect all reset sometime once sometimes multiple times. It occasionally does it when the car had only just started out but usually it is once the car has been driven for a bit. The radio has also gone into secure mode and has green secure showing. Sat Nav has never worked since I owned it. Any suggestions on how to fix it or what it might be would be greatly appreciated.
