It would appear that my stereo has decided to develop a problem....
Car is a 2010 Leon Cupra R
I believe it to be the RNS310 stereo.
Never had any problems with it before.
Firstly - Yesterday when I turned the key in the ignition the power didn't come on at the stereo. Didn't think anything of it so turned it on manually. Worked fine. But when I stopped the car it didn't turn off. Discovered that it no longer takes its switched power off the ignition but still turns on and off manually at the power button on the unit.
Also the stereo controls for volume and chanel dont work. All other functions on the wheel work, even the voice command which is on the same side of the wheel.
Lastly - The changes to the AC no longer show on the stereo display. Not that fussed about that one but strange that this has stopped at the same time.
All these problems appeared at the same time and apart form the issues above everything else works perfectly.
Any help appreciated.
