Hey mate, never really ended up finding out what the actual cause of this was but I ended up just pulling out my factory sat nav unit and it stopped the issue.
Not sure whether you get the beeping noises at every 5 min interval? This went away as we'll for me as soon as I got rid of the sat nav. Strange you are getting the this issue without he sat nav? I think from what the guy have translated above, something related to an error loading the disc?
Sorry I couldn't be of more help.
