The sat nav is playing up, unit on dash comes up no problem, but display says cannot read disc, used the Volvo cleaning disc and put back the sat nav one and says the same again.
Could this mean that the disc has now timed out?
Is there a better cd cleaning disc to use than the one supplied with the sat nav discs?
Sometimes it will work fine, when cold, but usually when the car has been used for some time and warm inside it doesn't see the disc.
Is this a particular failure of this cd driver box perhaps?
Any help would be much appreciated.
