Do you have an iPhone don, if so try the TomTom app. I got it for my hols in Italy and it was brilliant, western Europe maps for €69. Seems like a lot but it works without data roaming.
give him nothing , with any luck he'll end up in a Turkish prison servicing German Drug dealers !! that'll teach him to go on Holidays during the CLub league !!
+1 for TomTom on the iphone I use it all the time (like when ive been left behind on an epic spin and I want the shortest route back to civilization), If you get a hold of phone I'll show you how to get it for free, but i wouldn't lend the wife my iphone.
