DF-GM allows you to add two auxiliary inputs to the factory radio in select
General Motors vehicles. The adapter plugs into the factory radio using the
supplied cables, avoiding wire splicing and modifications. The DF-GM is designed
to co-exist with a factory CD changer, XM satellite tuner, DVD system, or
Control Mode: The DF-GM can integrate with
the factory radio using either the CD changer or XM Radio controls. If the radio
has CD changer controls but no changer, use that control mode and lose no XM
functions. If the vehicle has a CD changer and XM controls, use the XM control
mode and access the auxiliary input on the XM1 band, leaving the XM2 band
unaffected, meaning you have access to your CD changer, XM tuner, and auxiliary
sources. If using the XM control mode you'll need to splice one wire to the
factory XM tuner.
Mounting: The adapter can be
secured to any flat surface using the supplied mounting screws.
Connections: The adapter has
two auxiliary inputs (Audio Input 1 and 2) on the left side panel. Each input
consists of left and right RCA audio jacks. On the right side panel the adapter
has a round 8-pin jack that interfaces with the supplied CAS-F12
cable. The opposite end of the CAS-F12 cable plugs into the CAS-G7i cable which
plugs into the factory radio harness.
- CAS-G7i: Rectangular 12 and 24 pin
Molex plugs on each end (insert between factory radio and factory wiring);
Two rectangular 12 pin Molex inputs, for CAS-F12 cable and existing factory
- CAS-F12: Rectangular 12-pin female
connector on one end (plugs into CAS-F20 harness); Round 8-pin male
connector on the other end (plugs into auxiliary input module)
