Annoying beeping

[Surplusuk]

Just got a 2018 Berlingo Enterprise van with TeletracNavman fitted and I kept getting an annoying intermittent bleeping sound. I took it to Citroen and they say they have never heard the sound! 
It turns out that it was the satnav speaker installed under the dash on the passenger side. Some sort of interference. I have disconnected the speaker and the annoying noise has now gone. 
I’ve just got to get satnav speaker working again somehow. Off to Citroen after the Bank Holiday for their comments.

Does this only happen now and again?

If so this is probably the radio security function and will stop after a radio reset (press and hold menu until restart).

I have had the same a few times - I could bore you with the exact reason why it does it but just reset the unit and it will stop and work fine until it does it again in a few months.
