rds-tmc active mount not working anymore

[gluey]

Hi All,
I have a 540 live with an active mount which has a rds wire.
All has been okay until last navcore update.
Now it just keeps looking for a signal.
I have looked at my mctx.dat file and it contains the same as my backup.
I tried replacing the contents with "11110" as others have done.
Still the same.
I see there is two other files, fm2010 and fmsignal.
Whatare these for?

Any ideas how to get it back up and running?
