The problem is such that the display text for the TELEFON is not the way to go! Sometimes playing hard minutes, then returns to the front. The guide is not a word for such a thing! Put up a picture: http://www.upload.ee/files/2698007/DSC00238.JPG.html and also guide: http://www.manualslib.com/manual/18022/Blaupunkt-Frankfurt-Rcm-104.html , maybe someone can help track down the problem. Anyway, thanks in advance!
