I know we have a in-dash cd changer but does our radio also control another cd changer for the trunk? I am asking because in reading one of the how-to posts it says the pioneer rgb converter gets pluged into the cd changer plug on the back of the radio but it was done in a 99 tl..... just curious if it does support it I would like 2 changers hehe

 

yes. See one of the stickies in A/V forum.
