Dave.meredith85 Posted September 7, 2014 Share Posted September 7, 2014 Hi all, Newby to the forum as I only bought my 2005 350z recently. Just upgraded my head unit from the Bose CR330 unit to the Pioneer FH-X700BT and bought the correct harness to connect them all from incartech. I have connected the SWC interface they supplied the way they advised and it still does not work properly. The volume button on the wheel changes the mode (e.g. radio-aux-cd-bt) rather than adjusting the volume. Also I have lost sound quality and volume, which I am making an educated guess of putting the speakers through the RCA ports rather than the ISO. If anyone could shed any light would be greatly appreciated. Thanks Dave Quote Link to comment Share on other sites More sharing options...
psion Posted September 8, 2014 Share Posted September 8, 2014 Sounds like the swc is connected the wrong way around. Yes the speakers need to be connected to the RCA's as you are now double amplifying them using the head unit and the bose amplifiers in the Z Quote Link to comment Share on other sites More sharing options...
N4eay Posted September 9, 2014 Share Posted September 9, 2014 Hi, I'm a going to be installing the same HU at the weekend, have you overcome the difficulties you experienced? How's the sound quality, might need to do the buster mod, connecting the speaker wires to the RCA's. Thanks Quote Link to comment Share on other sites More sharing options...

GIXXERUK Posted October 8, 2014 Share Posted October 8, 2014 I have exactly the same issue with the swc when replying to a post like this, where you are wondering if they have resolved the issue - either PM the posters or multiquote, that way they will be notified that they have a reply in this thread (unless they have turned the notification off) Quote Link to comment Share on other sites More sharing options...
