GPS 'Breadcrumb' device

[Pooleman]

I am planning on driving for 3/4 weeks through Europe later in the year and I was enquiring as to the availability of a GPS device that would accurately record the route taken, for the full duration of the tour. I don't necessarily need it for live navigation but simply a 'breadcrumb trail' record.

Any ideas please?

Thanks for the information, one further question, on some of these devices, a different memory is required for each Country visited. Is there something available that I can just leave and forget?
