I did a search and all I can find with regard to radio issues is no sound. My radio when the weather got cold will not come on the audio off is on the screen. When I push the on button nothing happens. I have pressed it many times . I have also tried the steering wheel mode button. Then later in the day I am able to put it on and then off. When it works its works fine. I have reached under the seat and made sure all connectors are in. All of the steering wheel buttons function as they should when the radio does work , I don't know if the change in weather might have anything to do with it . I thought maybe cold weather could shrink connectors that's why I checked them. The sound works on the navigation when the radio acts up and wont work so I figure the amp is ok unless there is a different power source for sound on the navigation speaker . I would appreciate any advice on where to go from here. It has been working ok for a few days but it still has this fault occasionally
