What is the "traffic" feature on the TomTom XL 350TM (GPS system)?
Does this mean that I will get live traffic results when I use it? Or do I download traffic like downloading maps?
Another related question is how does this differ from the TomTom Live units?
Help pls :)

Traffic / TMC
instead of LIVE Snapshot / HD-Traffic, some models come (only) as Traffic which makes use of an (EXTERNAL) radio antenna to receive TMC (Traffic Message Channel) sent out by some radio stations. TMC is updated only every 15 min (+ or -) and covers only highways.
LIVE snapshot
the TomTom includes a SIM chip (like the ones used in a mobile phone) to receive up to date traffic informations collected from mobile phone customers; this information is collected anonymously from the GSM antennas and includes position and change of position of many mobile phone users. that data is then sent to every TomTom equipped w/ LIVE snapshot / HD Traffic every 3 minutes or so.
IQ Routes™ technology
based on the data collected for HD-Traffic users, TomTom has compiled statistics for the traffic of many roads (not only highway) for any time (5 minutes grid) over the week and depending on the season (vacations aso.)
