Installation:
The factory radio model name can usually be found in the front lower left corner
of the radio. If the vehicle has a VES (Video Entertainment System), it must
be disconnected! This interface is not compatible with REF model radios.
They do not have a VES input available.
1. Remove factory radio. Remove factory female 10 pin Satellite cable, if avail-
able. Plug the ISCH73’s 10 pin SAT plug into the radio. Plug the factory Satel-
lite cable that was just removed into the ISCH73’s 10 pin connector.
2. Insert the ISCH73’s 22 pin main power Plug (T-Harness) in between the fac-
tory radio and factory harness.
3. If the vehicle has both factory Satellite and VES, you must disconnect the VES
at the overhead unit. The Satellite radio will still be available for use.
If the
vehicle has factory single disc radio (REF), this interface is NOT com-
patible.
Refer to vehicle’s repair manual for location and removal of the VES
plug.
4. The ISCH73 output plug (3 pin connector) must be connected to the VES
input harness of the 10 pin T-harness (Purple, Black, Green).
5. To activate iPod® mode, press the MODE button until VES is selected. When
Chp 1 is displayed the iPod® will be the selected source. If Chp 2 is selected
Aux 2 (standard RCA input) mode will be the selected source. Pressing the
MODE button will select either Chp 1 or Chp 2, alternating each time the VES
mode is selected.
Chp 1 - iPod® mode
Chp 2 - Auxiliary mode
Note: The ISCH73 will emulate the VES only! If the vehicle has factory VES
it MUST be disconnected. VES does NOT operate in R.A.P. mode. The
radio will automatically switch to tuner mode during R.A.P. (Retained
