Radio went dead then next day the keyremote stopped working.

Check the fuse it’s probably bad

Check your battery and cable and ground connections. check also your alternator belt (drive belt). Have your battery checked at any autoshops.

On the components, you might try a separate ground. See if that helps? Check the battery negative connections. I've seen this even on newer vehicle where instrument cluster or whatever would dim a little when you turn on headlamps. I think it's a ground issue? Just my opinion.
On any component that doesn't work, check voltage and ground, you could try a redundant ground.

radio went dead...one day working fine, nothing next day. Checked the fuses all good. Any solutions???

There are 2 fuses linked to the clock; 1 is connected to the radio and the other to the gauges. If the radio and gauges work then the clock is dead, it is a very common issue with these clocks. I have a repair service, check out www.autoclockrepair.com. I have removal instructions, etc there. Please le tme know if you have any questions, I would be happy to assist, thanks!

I have the same problem, after couple days of not driving it the battery went dead. After charging it back up the radio worked again, but then started doing some other freaky things. Any solutions out there?

Hi All, the very same thing happened to me. Cold weather broke my radio and the display screen stayed on with the time and temperature but the radio wouldn't work. I rang Renault & they said I need to come in an get a new radio but I put it off. In the end the problem started affecting my battery and the car wouldn't start. But then when I jump started it, it also started the radio again perfectly. Problem solved!
Hope this helps. Good luck!

it sounds like the Multi information display has failed (MID). It is the long display with all the radio controls on it. If you want to find a known good part they are really easy to swap out. Just remove the radio knob and if you look down in there, there is a place to put a T10 (i think maybe bigger or smaller) torx T10 screwdriver.if you turn it while pulling back slightly on the screwdriver it should come right out. It usually is the component that fails but as always you may want to check your fuses.

Check your fuse more then likely it blew. Car radio Clock and Cigarette lighter all connected to the same fuse.

I found a solution that sounds reasonable at another site: http://www.automotivehelper.com/topic177704.htm
