I have a Citroen c5 from 2011 with the l2012/2013 maps installed.
Today it started to be without sound during bluetooth phone calls.
I've soft reset the radio and remove the pairing from my Iphone. Even tried with a Samsung galaxy. But the problem continues.
Is there a way of making an hard reset to the car radio ?
Does anyone has an idea about solving this ?
Are you sure you have a myway (and not emyway) unit in your car? My C5 is 2010, and has a myway (RNEG) and upgraded it to the latest available R50b firmware with no problems ... maybe you actually have a emyway (RNEG+), same unit visually (different manufacturers: Harman Becker for the older, Magneti Marelli for the newer) as the older one, but firmwares aren't compatible ...
Yes. My c5 is from 2011 and also with the same radio as yours.
But, I've copied the firmware files to another sdcard and it worked !
Not only worked the firmware upgrade as also the Bluetooth was fixed !!!!
Now I can hear again the contacts talking to me. And this is the strangest thing: the phone sound disappeared once some months ago, and not even with a hard reset it came back.
Now, a simple firmware upgrade and it is solved.
