I have just upgraded to a columbus HU on my OctyVRS. Surprised at the accuracy of the TMC information. Rush hour traffic shows up brilliantly. So investigated settings. TMC set to auto is picking up a channel called Free C&W which I presume is Coventry & Warwickshire as I'm in Coventry. The unit obviously is connected to the web so I can only presume the radio is using crowd sourced data which is brilliant. However if I press the TMC button which shows all the alerts about traffic they are the usual classic FM ones about major motorways and not the local ones my unit is actually showing and what I really need.

I also have a Freelander 2 with a factory fitted Satnav with TMC. On this unit the auto selection will only choose classic FM as the source and manual brings up no other option either.

So how is the Columbus picking up his good stuff and do people in other areas get very up to date TMC info as well? If not it might be worth checking your settings as I find classic FM info next to useless and hopelessly outdated.

Can't tell you about the TMC, but Free C&W is indeed Coventry and Warwickshire. It was Mercia Sound / Mercia until March 2012.

TMC information - you can read up on it here :- http://en.wikipedia.org/wiki/Traffic_message_channel#United_Kingdom

The Columbus isn't web-enabled though.

The TMC data is picked up over the FM band and not the internet. What you get is only as accurate as the source data provider, for the UK this is a multitude of sources including Trafficmaster and the Highways Agency. You'll find it more accurate on some roads than others.
