Tomtom6250 trucknav install loop

Good evening all. My tomtom was working fine, I got out to offload the trailer, was about an hour offloading. Came back into truck, on screen was picture of tomtom to connect to computer. What I noticed prior to this was the screen flickering on and off as if it was closing down then not every few seconds when I switched ignition off prior to offloading. But I didn't think that would create a total wipeout and corrupt the thing?

I have connected to my drive connect, all my machine is doing is an install loop. The unit is about 18 months old. Can anyone suggest anything to get round this problem?

Many thanks
