Looking at 520 WiFi in local shop I am unable to determine if rds TMC supported?
Live traffic via app on phone not always possible (needs app running on phone ☹️)
How can I check?
My present via 130 has special cable with built-in receiver)
The 520 doesn't come with access to TMC 'out-of-the-box', however you can buy a power cable with a TMC receiver built in to it which the 520 will recognise and provide a TMC feed from that.
