With tiresome predictability, the infotainment system on our Citroen decided to f*ck up on the first long journey in 18 months. Set off with my phone playing a podcast via bluetooth and 5 minutes into a 3 hour journey the console started restarting every 3-4 minutes.
After some googling, I saw a repeated suggestion that tuning the DAB source to "Absolute Radio" (even though you don't then select the source to listen to would cure it).
And - after 3 weeks, it seems to have done the trick. Which I accidentally confirmed by trying to find my local radio station on DAB instead of FM.
DAB, eh ? I'm still living without it. What a crock.
