We just got back from a trip to Northern Ireland,which I highly recommend. While researching a rental I saw that they will rent you aGPS, but it's really expensive. I already have a Garmin DriveSmart LMT 6 so I bought this chip to allow me to use it in UK/Ireland. In general, it worked very well and got us where we wanted to go easily.It was nice having my own GPS which I'm very familiar with too.There is one thing to be aware of though. The GPS is set to take you via the theoretically fastest route but if you're touring for scenery that may not be what you want. There is no ""most scenic""option. For example, while navigating the Antrim Coastal Route (one of the most scenic drives in the world) to Belfast, the GPS kept trying to get me to take little tiny roads,away from the Coastal Route.Unless otherwise noted, the speed limit in Northern Ireland is 60MPH, but you could never drive those exceedingly narrow roads that fast. I'm talking weeds brushing both sides of the car at once narrow. You might want to try one or two of those roads for the experience, but they are almost never the best route. Plot your trip out on a good paper map and ignore the GPS when common sense tells you you're deviating from where you really want to go.
