Kilikis says not much use in Crete. Echo that. Friends staying in Kalyves wanted our postode to get from there to Kokkino Horio using sat nav. Putting in 73008 wasn't a great help!
Never pay extra to add one to a hire car. I bought one for not much more than it would have cost for two weeks hire. I've used it for about 10 trips to the UK and France and I think Scooby has also used it about five times so it was good value for money. In the UK they couldn't be easier to use. Put in the post code and the house number, press "navigate" and it will take you to the door. Presumably your friends thought it would work the same here. You can also store what you put in as a favourite and then just call that up when you go again. Quite useful for finding your way back to the hire car depot if it is off airport and you haven't used it before. Simply store the current location as a favourite before you set off.
Your friends could have changed the input method from post code to latitude and longitude then you could have looked those up for your house on Google Earth and sent them to them in an email. That is how I use it in France, since Cedex seems to work more like Greece and you have to also put a street name and number. Like here, not much good in rural areas where the property is outside the town.
They can be very useful, especially when you don't have a navigator, and I think the horror stories are pretty rare but not very nice if you suffer one. I've no complaints about the Tom Tom device itself. Apart from a minor problem when it screwed up a map update, which took a bit of effort to solve, it works pretty well. If you deviate from a route it tries to get you to go back but not for very long and after a short distance it recalculates the route. One that was built into a car I hired kept trying to get me to go back for miles before it finally recalculated. Also the updates can be phenomenally expensive for built in ones since they often have to be done by the dealer. I wouldn't rely on the speed camera warnings. I find they tend to give a lot of false positives and also fail to spot many actual cameras.
