What model and options do you have. Also what country are you from.
We have vehicles from all over the world on this forum and they do not have the same options or packages. Someone with the same vehicle as you have may be able to help.
Well, after many unsuccessful tries to find the solution I decided to get the kit from Beat-Sonic (http://www.beatsonicusa.com/). They have a group by and the price is just great. Now I have to find the proper way to open center console and take the radio out.
