Is it possible to change the station providing the TP updates?

Everything seems to come from Heart, and yesterday had no updates at all, and when you do they are so out of date!

The Mondeo got all it's updates from BBC stations and Classic FM and was always up to date and accurate.

again another day with zero traffic reports.

It's likely because your radio is tuned to a commercial station (probably Heart?) - you'll only get the BBC TP reports if you have tuned to a BBC station (local or national).

Listening to radio 1. I don't listen 5o commercial stations or Heart!

Sat nav units will pull text reports regardless of station listened to. Mine isn't.
