Works for a lot of people on the RRS L320 site. Clear strong DAB with little drop out and loads of channels. Everyone seems to have the same slight quirk in that switching between normal radio or cd to DAB means you have to switch off the audio and switch it back on. DAB then come on fine. If you leave it on DAB it stays on DAB but you do need to operate the volume button, almost like a switch, to effectively switch the DAB on.

This seems to happen with the old DABs as well as the new DAB+ when changing modules, so something obviously quirky in the programming files for the head unit.

Doesn’t cause me an issue and so nice to have DAB back again and working.

Plenty of DAB+ units on eBay, although some can be a little pricey. You should be able to pick one up for around £100.

The DAB+ unit is part nr CPLA-14F720 followed by B (for DAB+) and another letter, the higher the letter the more modern the firmware.
