My Clio radio has started to turn itself off after 20-25 mins. Beeps twice, display flashes, then switches off. You can turn it straight back on fine. Also, now when you turn the ignition off/remove the key, the radio stays on and you have to turn off manually.

My local car radio specialist couldnt help - indeed he said he had a renault which did just the same and he couldnt find out why despite removal. He suggested that "somewhere" there must be an auxilliary feed with fuse, but could not find it. The main fuses by the passenger door are fine. Have tried emailing Renualt but they wont reply.
