PXDXGM4
Quick Start Install Guide for select 1997-04
Corvette
Revised April 8, 2019

Introduction:
Many Corvette Owners looking for an easy an effective way of connecting and
listening to their portable audio devices on the factory radio will be pleased to
find the PXDXGM4. Connecting an Auxiliary adapter to most GM’s usually requires
disconnecting the factory CD Changer**.
The PXDXGM4 connects to the radio in 1994-04 Corvette C5. CD Changer (if
present) must be disconnected, but with the storage capacity of most
portable devices, sacrificing the CD Changer should be an easy decision.
Installation: (To Radio)
This adapter connects to.
Remove Radio from dashboard to gain access to the connectors. ( Click link
