2014 Escalade is not compatible with GM2

Post by shern » Mon May 14, 2018 11:45 am

Installing Kenwood DDX9905S into 2014 Escalade ESV with factory navigation.

Both iDataLink and Crutchfield call for usage of the GM2 Maestro adapter cable. However, the GM2 will NOT work with the 2014 Escalade navigation. The navigation system utilizes the legacy multiple connector setup from previous years of GMT900. Picture is below. I have ordered the GM5 install adapter and will attempt to use it. I recommend iDataLink to investigate this.

However, I'm concerned about the Firmware on the Maestro RR itself. If the GM5 works correctly, will the firmware be the same?

The GM5 is correct for this trim of the Escalade. This body style of vehicle always gets the GM5 firmware, regardless of what harness you use, so you'll be good to go. I'm so sorry about that!

We are working to decipher which RPO codes indicate which plug the radio has (it is ALL over the place the 2013-14 vehicles with nav).

Thanks Dara. Perhaps we talked on the phone.

I received the GM5 today, wired it all up and so far so good.

However, I have no subwoofer. No matter what RCA output I connect the sub to, I get no sound. Any ideas?

Curious...... it appears only the front RCAs are enabled on the GM5. However, the fader is enabled. I’m curious to know how the fader is controlled by the maestro.

If it's premium bose, the fader is digitally controlled.

In some trims of Bose, there is a dedicated output for the subwoofer. If you plug in the third plug on the GM5 harness and trace the subwoofer RCA's wires across to the factory side, are there wires there? If not, the regular speaker signal is being fed to the amp, and that is crossed over to create the audio for the subwoofer.

Quick followup

All audio in the Escalade Bose setup is transferred into the GM5 harness through front L/R input (white/gray low level input). The dedicated sub/center input (brown connector) and rears inputs (purple/green) are not used.

The crossover on my head unit was enabled which indirectly killed the SUB output. Once I disabled the FRONT crossover, voila, everything worked perfectly. It's imperative that the connected head unit output has all crossovers bypassed.

Anyways, just wanted to share my learnings for others in the future. Thanks again Dara for the support.
