I have a 2011 Renault Scenic. That handfree device conneted without problem to my Galaxy S1, but since changing to an S2, I can get the deviced paired and the incar system shows connection presenr, but I cannot make or rceive calls. (If I dial a number, the car sound system does not operate; if I receive a call, I cannot answer it either from car system or from Galaxy and the cat system does not indicate incoming call. The system works ok with Nokia Navigator or an I-Phone. Is this a Samsung problem?
