Had not the year of construction of a Peugeot 307 (2005-> RD4 radio) respected and therefore ordered this adapter. He can not be so easily translate from ISO to quadlock (with an additional adapter). In NIQ called described the dilemma and the very next day the correct adapter was there.
Now comes yet: send in the wrong and pay the small extra charge of quadlock adapter.
There are still 5 stars because of the service of knotless NIQ. Incidentally, does the New properly.
