07 T180 Sat Nav - Not Recalculating After Wife "pushed A Few Butto

[auf_wiedersehen_pet]

As the title really. It's been fine since purchase three years ago but it's recently stopped recalculating routes if you stray from the blue route.

My wife fiddled with it!!

We've gone through the menus/manual/Google but can't find anyway to correct it.

Any help would be greatly accepted.

Not knowing what type of satnav you have may make it hard to sort.

I used to have an Avensis 2001 with the TNS200 fitted.

When it went t**s up I ejected the cd and then left it for 20 mins.

When I re-inserted the disc all settings were back to default and any POIs were deleted.

But at least the system worked again.

Maybe you could try that and see what happens.
