so here it is the latest piece of the puzzle, rns-e 193 G.
big thanks to lala30 who helped to fit it, rewire aux in and code all thing.
without him i guess it would take much longer to make it work.
had a little issue with dvd drive as i tried to put mp3 cd to see if it works and it got stuck, but managed to make it work without dismantling the unit and now it loads, plays and ejects discs perfectly.
love the sd cards and the music from them.
