I just bought a Tom Tom 350 tm do not understand how traffic works
There are two different systems being used to deliver traffic data. One comes over a subchannel of local FM stations. It's called RDS-TMC or similar depending upon which side of the ocean you're on.What is the difference between Traffic and Live?
The TomTom units with which I am familiar allow you to specify what you want done in the event that traffic is found on your route. (Note: I can't speak to the awful "EasyMenu" versions -- it wouldn't surprise me if they'd pulled the more useful menu options regarding traffic along with the list with which I've grown familiar in these threads). For those I've actually used and know, I've got them set up to prepare a new route and ask if I want to execute it or not.Thanks. Does Traffic also seek alternate routes?
...Too often the traffic data (even Live) is old enough that the situation has actually cleared up, and a reroute is going to cause an additional delay. This stuff is all pretty early technology and can't be relied upon for rock solid information, no matter which version you've got.
With traffic, a "good" alternative would be expected to reduce your travel time. The TT will take your current situation, with delays, and compare to any alternate route. If the time to destination appears to be shorter with the alternate, it will recommend that. On the other hand, it may instead advise that there are no routes that would improve on your existing situation. It will let you know which is the case and you can make your decisions from there.Do the regular "find alternate route" option and that option under Traffic work differently from each other, or do they really amount to the same thing? I have not found the regular "alternate route" too helpful.
