When we went to the UK a couple of years ago, the rental company wanted a 17 pounds per DAY for a hire GPS. We went down the road to Halfords (auto parts store) and bought a Garmin with UK and European maps for half the price of the hire fee. (I did have to change the settings to metric even thought the UK uses miles because I'm so used to using km.)
When we got back to Australia, I bought the Australian/New Zealand maps for $20 off eBay. The GPS works fine here and also did in New Zealand on our last holiday to the South Island.
