Just put a new Pioneer head unit in the son's 2008 Altima. Also installed an Axxess Interface ASWC-1 module to allow use of the steering wheel controls with the new head unit. The steering wheel on/off hook for the phone doesn't work though. Instructions say to install certain jumpers in the Bluetooth Module harness, but it doesn't tell you exactly where that harness is. Says it's in the trunk. Anybody have any experience with this?
