This is my code (I write the essence only) and I get this:

error: no match for ‘operator<<’ (operand types are ‘std::ostream aka std::basic_ostream’ and ‘void’)

class Mobil 
public:
void print() const; 
int getNumber() const;
double getData() const;
friend ostream& operator <<(ostream&, const Mobil&);
;

ostream& operator<<(ostream& out, const Mobil& mobil) 
 out << mobil.print() << endl;
 return out;

what is the problem?

Problem is this line: out << mobil.print() << endl;. Your print() method doesn't return anything (is type of void), so it can't be send to ostream

To solve this problem, your print() method should return whatever you want to printout in one of types supported by ostream which you can find in reference.

Or it can take std::ostream& and do whatever it needs to on behalf of the operator<<, though this is arguably less idiomatic nowadays.
