Hi Guys - thanks for your reply - love your U Tube and congratulations!
Guess we have a language barrier problem - we are used to those right?
Walking translated to you I guess to you means hiking!
Since I posted I have learned more about the Hiking GPS that I bought over the net from USA (had to pay Spanish customs import tax) its an Garmin ETREX Vista HCX - you name it - it does it!
Having tried to get digital Spanish maps on the cheap and failed I have paid the 150 euros and bought the Garmin CD containing the maps of Spain from a Spanish supplier and that will be this weekends project! Given the current wet weather probably not a bad idea.
Carry on enjoying Barcelona and I hope the hiking is good - I will have to come down and try sometime - with the GPS I should be able to find it!
