The large wide screen is extremely clear and easy to see. The GPS itself is extremely well built, with a slightly rubberised casing, which makes it easy to grip.
The 540 does not come with an MP3 license, so you can't use it to play music whilst you drive. You can buy add-on maps at a later date, so it is possible to buy the 540 and add the Europe Maps with an online download. The 940 also Includes the US and Canada.
These devices have similar functions, and the main difference is the maps: The TomTom Go Live series in the UK has the TomTom Go Live 540, Tom Tom Go Live 740 and Tom Tom Go Live 940. There is a different blog entry for the Live services, which can be found here. GPS - 9/10 - A well engineered device, with good quality accessories. Following the purchase (and return) of a Navman S80 Deluxe GPS, I plunged for the TomTom Go Live 540, and haven't regretted it since.
