2010 Fiesta Stereo issues

[Strange1]

Hi all!

So I've had a 2010 Fiesta Zetec for the last few years as a run around and it's been good, but I have this sporadic bizarre stereo issue.

I normally listen to stuff from my phone over BT, but if I change the input from BT to Radio or USB it will go massively distorted and way too loud even at volume level 1. Sometimes it changes the input itself with no intervention. This only happens maybe every 3 months or so, and it might do it 2 or 3 times in a row. The only way to get the stereo to work again is to turn the car off completely and restart it, then it's fine.

I can't find anything about this happening through a search so I'm just curious if it's just me?
As I said it doesn't happen often but when it does it scares the ***** out of me lol!
