Did you get it sorted and does it work now ?Have the same issue on a 65 plate 1.2 Juke. Phoned customer services on 0330 1231231 told them the blutooth and radio keep randomly dropping, going off and that I'd heard there was a free software update to fix it. They confirmed and emailed me saying
"Please ask the dealer directly for a software update related to the DAB system.
The dealership should be able to complete this software update for you free of charge."
Haven't had it done yet, but keeping my fingers crossed.
