I bought the TomTom Go in August after a bit of a cash windfall and a lot of thought. I've always been a GPS user (Garmin, Magellan) but had never owned a vehicle system before. My initial impression was that it had a great screen (very clear and easy to follow), seemed intuitive to operate and was amazingly accurate. I love the variety of voices and have even used some of the European languages for a laugh. I finally ended up with 'Jane' (English UK) and I even talk to her sometimes . . .
The map and zoom features are a bonus when searching for a particular point and it uses addresses, not Postcodes, as destination points. It also allows you to record your GPS position and any location that you tap on the map screen and use them as destinations or waypoints. The screens are exceptionally clear except for the data section at the bottom right of the navigation screen which I can't read because the numbers are too small, but they only cover things like ETA, distance remaining etc. The actual 3D map is superb and the visual warning of the distance to the next junction and what sort of junction it is (which way to go when you get there) make it an excellent aid to reducing stress.
In the first month of use I found my way round Glasgow, visited Liverpool and toured the Lake District with my brother who was visiting from Australia. He started talking to Jane as well . . . It was phenomenal and on the rare occasions I doubted it and ignored the instructions, I was normally wrong. My only complaint (if that's the right word) is that there are inaccuracies, because roads change somewhere in the country on a daily basis and you must be prepared for the odd glitch. As examples I have encountered the following problems.
1. An entry slip road for the M77 in Glasgow is on the wrong side of the road (according to TomTom Go) and it tried to make me cross the carriageway.
2. A junction near Ibrox stadium in Glasgow does not allow right turns but the system tried to make me turn right.
3. I've hit a couple of one-way streets that the system didn't know about.
4. The exact location and layout of the street I actually live in is spot-on (on the map) but the road name is completely wrong.
However, don't be put off. After 2,000 miles of driving I've hit no more than half a dozen inaccuracies, though I'm still working on how to report them (and who to). The beauty of the system is that if you miss a turning the system will attempt to quickly calculate a new route for you, normally with excellent results. I'd give it 9.99999 out of 10 - it's excellent value for money and a fraction of the cost of some systems. Being a moveable system also means my kids can borrow it and I can use it in other cars. I certainly have no regrets and would recommend it to anyone. If I win the lottery I may even give some as presents.
