HI this is my second posting here.

I'm Sorry about my bad english, because I'm korean.

I have 2012 mcs with radio visual booster, usb,bluetooth only for calling.

I don't have mini connected, no navi.

so I'd like to activate bluetooth music with my Iphone.

I checked my vo and I got $6FP,$6ND,$6NM(that is I coded it)

So I tried to code my vo add $6Vc,$6NM,$6NE to Cas, FRM module.

and finally I got the media module!!!!!( I don't have it before)

Afterward I tried to read media module but I can't.....
