Garmin Nuvi hidden menu

[gem]

In trying to understand the TMC outputs (or lack of them and poor coverage) what do the codes mean in Nuvi's hidden TMC screen please.

And can these codes be translated into something I might understand?

e.g. Channel? does this value correspond to a specific radio station

e.g. CC what does this mean?

e.g. Errors means what?

And which is the signal level code as it doesn't specifically say that term.

Cheers.
