Another thing that really annoys me about TomTom is the inconsistency of directions given at roundabouts. At one roundabout I use often, the instruction given is "cross the roundabout, first exit" in one direction, which should actually be "go left on the roundabout, first exit". In the reverse direction it says "turn right on the roundabout, second exit" which is correct.
At another roundabout, routes needing a left turn are announced as "cross the roundabout, first exit" instead of "go left on the roundabout, first exit", and routes requiring you to go straight on are "cross the roundabout, second exit". The roundabout has 4 roads all at 90 degrees to each other, so at least one of the directions given must be wrong.
Of course the map on the screen always tells you where to go, although the slow speed of updating while you are making a turn can lead you to take the wrong route if you aren't careful. I have learned to look at the map *before* entering the junction.
Today I found a dangerous flaw. I was approaching a roundabout where road signs told me I needed to go right on the roundabout, third exit. TomTom said "turn right". I looked at the map on the screen and, to my horror, the green route shown turned right on entering the roundabout and actually went around the roundabout the wrong way, against the traffic! I doubled back and did the manoeuvre again, with exactly the same result on the TomTom. I hasten to add that I went around the roundabout the correct way, both times!
I am by nature a very precise and often pedantic person (Asperger syndrome) and I get very upset when simple rules are not followed. The wrong verbal directions given by TomTom irritate me a lot, but I can just about live with them, as long as the map on the screen shows me the correct route through the junction. But I cannot accept a map that tells me to drive the wrong way round a roundabout. Grrrr!!!
