Help re GeoNav 4c

[Jimco]

I've a problem with my GeoNav 4c chart plotter as I can't get beyond the initial "welcome" page and I can't see any means of resetting the unit. Seems as if the application software is at fault. GeoNav not responding to messages sent via their website and can't find a UK based agent who could check it out for me. Can anyone help with advice or name of potential repairer?

GeoNav problem

I have an identical problem with my GeoNav 5 Touring GPS. Does anyone have a solution?
The unit frozen recently after I powered off from the power supply instead of the on/off button on the chart plotter.
