How to reconnect DAB fm?

[yahoy_]

Bought a 2017 Aygo, and i was fiddling about with the DAB radio. One minute it was playing fine, but once i clicked the little square buttons, it said no signal. Have no idea what to do. Any help would be great thanks!

(Also the image attached is an example of what radio i have)

You more than likely need to retune the presets for the dab for your local area - 1 to 5 are the station presets - tune to a station using the centre knob or up/down arrows - to set it as a preset, press  and hold the button below the number until you here it beep - repeat as required

instructions will be in the owner's manual for the basic radio
