I have a 2017 208 1.2 PureTech (110 bhp). I use Android Auto on my phone via USB. Everything has been fine until now after a service, when I plug in the USB the radio changes to USB instead of FM and I can't get Auto to run on screen. How do I get back to how it was, please. I change the radio back to FM and reconnect the usb, radio defaults, help please.
