I got a decent deal on a leftover but new 2008 4Runner and have read conflicting reports on whether or not the TOY-SC1 is compatible with the JBL Navigation System/4 Disc changer that is available in them from the factory. Anyone know first-hand or have solid evidence one way or the other? I am looking to use the TOY-SC1 along with a SCVDOC1 (or whatever is out there now) to use my Sportster 4 in. I think I can hide the S4 and its dock in the console. What say ye? Possible or no?
