I have a 2008 Silverado Ext. Cab without the bose system in my vehicle. I purchased a Pioneer Head Unit and a Axxess GMOS-LAN-02 wiring harness without doing much reading. I realized after looking at the packaging that the GMOS-LAN-02 supports amplified systems (aka Bose Audio) systems but doesn't specify if it supports non-amplified systems. Should I go ahead and exchange it for a GMOS-LAN-01 or try the current one?
