I have one not sure if its the 500 mine doesn't have europeon maps. I havn't used mine much but when I have and I took the wrong exit off a motorway (my sense of direction is not too good) I pulled over as soon as I could punched in the address and bingo It got me there safely. I do know that they do not always take you on the most direct route but there very reasurring if you're not sure where you are going They have 3 or4 different voices to choose from so its easy on the ear. I got mine from Currys. Not cheap but a neat little gadget
