Dave,
Good points. It's why I also mapped out the routes using AA in Ireland (sorta like our AAA) and took a good atlas with me.
It's always good to have a backup- you never know when the battery won't hold a charge, the lady in the GPS has a brain freeze, etc.
We had some minor instances similar to yours but by looking at themap and picking a town name we got back on the right road quickly.
