Liked the GMOS-04 Better
My perceived Metra GMOS04 benefits over PAC OS-2BOSE:
RCA Preamps in the harness (Installing AVIC Z110BT)
Chime sounds like factory
Better instructions for Corvette (although I did have to chase down VSS and reverse)
No additional chime module required
Doesn't sound any worse that the OS-2BOSE
