@salty @Tuareg the MG4 radio sounds fine, it doesn’t work fine.
It’s the user interface that’s daft.
Try these tests from simple to more complex:
Select 107.1 MHz while driving.
Save a frequency with a station, then drive to the edge of the station’s coverage area and try to recall that frequency from favourites.
Save a networked station with RDS AF (Alternate Frequency to facilitate auto tuning) drive through an area with no coverage for a bit and then into an area with coverage but on a new frequency. Does the RDS AF recover?
As above but drive into an area where one of the RDS AF network frequencies has unrelated station with a different PI (Program Identification). While you listen to your wanted network, the radio interrupts the program by switching to the unrelated station every minute or so.
Even with the RDS faults, if you could simply choose stored frequencies I wouldn’t complain.
The radio picks up weaker stations fine but won’t let you recall them from favourites and doesn’t display the selection.
I drive 150km per day and listen to news radio (BBC, RNZ, etc). If you listen to one strong local station you won’t have a problem.
