that will tell you what parts you need.

totally trolling this thread, but says the gmos06 is only for onstar intergration

what you could do it pull the radio out turn the car onto ignition and if it chimes, there should be no need for a lan harness, only thing is u may need to run your own switch power dont remember exactly on that car.

He never said he didnt have onstar though. It will most likely have Onstar.

i know i was just saying he may not need that harness.

if there is no onstar and no chime it would be the 70-2001 harness

Idk what you're looking at but Metra shows the only compatible harness for an 02 Deville is the GMOS06. Which means it doesnt (shouldnt) have a no-onstar option.

Description GMOS-06 $75.44

CADILLAC RCA INPUT 2-CHANNEL

Product Specifications

For 2000-04 Cadillac with premium or Bose
USB update interface compatible

The GMOS-06 interface is designed to allow the user to replace the OEM radio with an aftermarket unit in amplified Cadillacs and retain full functionality of the Onstar system as well as all safety and warning chimes. The GMOS-06 will also retain the retained accessory power convenience features. This interface has the capability of adjusting chime and Onstar volumes as well. In addition to these features, the GMOS-06 now has the required outputs for the installation of a navigation radio.

Online price is always cheaper than MAP from a local store.
