Garmin Traffic Questions

1. Does anyone have a list of the traffic channels that maps to the FM frequencies? The GTM Status page lists channels, but not the radio frequency. Because of frequent channel changes, I haven't been able to map this.
2. Navteq owns Traffic.com (nee Mobility Solutions) which is a major traffic provider and has a huge network of sensors. Where do Clear Channel owned stations using their "total traffic network" derive their traffic data?
3.) For areas with free RDS-TMC traffic service (e.g. French Autoroutes), will my Garmin pick it up automatically? Or will I have to install a "subscription" to get the free data?
4.) Why does a Clear Channel subscription show up as a single provider, but with a Navteq subscription, each station is listed separately on the GTM Info page? Also Navteq stations show up as "unnamed."

Where do Clear Channel owned stations using their "total traffic network" derive their traffic data?
Their own first-hand reporting into their own data network - reporting what their traffic reporters at their O&O radio stations see themselves, and observe conditions from automated monitoring systems & "trip guide" cameras, & twitter feeds operated by government entities in metro areas, and reports from other drivers who may call a radio station's traffic tip lines.

Simple Math
1. Does anyone have a list of the traffic channels that maps to the FM frequencies? The GTM Status page lists channels, but not the radio frequency. Because of frequent channel changes, I haven't been able to map this.
It is a simple equation:
Frequency = (Channel Number / 10) + 87.5
For example, if you are seeing channel 152 then:
102.7 = (152 / 10) + 87.5
