Our take on the iDatalink Connec ADS-HRN(SR)-GMS05 Factory Integration Adapter

by Dave Delamere

This iDatalink ADS-HRN(SR)-GMS05 wiring adapter from iDatalink allows you to connect a new car stereo in select 2006-up GM vehicles, working in conjunction with iDatalink's Maestro ADS-MRR module. Once connected, you'll retain the use of your steering wheel audio controls, your factory amp, safety warning chimes, and OnStar, if present.

The package includes connectors that plug in between the Maestro module, your GM radio's wiring plugs, and your new car stereo. You'll have to solder or splice together this harness's power/ground, illumination, speaker, and navigation output wires to the corresponding wires on your aftermarket receiver's wiring harness.

Installation note: This adapter must be used with the iDatalink Maestro ADS-MRR module to connect a new car stereo to your GM vehicle.

Easy to install

Written By Todd, TX on Monday, June 30, 2014
Crutchfield Customer Review (What's this?)
 
Very easy to install and directions are pretty straight forward.
Pros:
Easy to hookup
Cons:
So many wires makes it hard to cram behind radio. When I switch over to using RCA instead of speaker wire that will clean up a lot.

Great product

Written By Jeremy C, Tullos, LA on Saturday, May 10, 2014
Crutchfield Customer Review (What's this?)
 
First thing is you also have to have the maestro box too. I thought you only needed this but ended up having to wait on the box. It's all color to color wiring which is pretty easy. Don't get intimidated looking at all the wires it's not that bad. Over all good product.
Pros:
Colors matched with radio wires good, made the maestro box installation easier.
Cons:
Didn't know I had to have the maestro box too (sold separately). Instructions are online.

2007 Chevy Equinox

Written By 04dawg, Olive Branch, MS on Tuesday, February 11, 2014
Crutchfield Customer Review (What's this?)
 
Easy, easy, easy...unless you're color-blind. :)
Pros:
Color coded perfectly.
Cons:
Needed to put a resistor in-line for proper control of the stereo (unit kept changing sources without anything being touched - Pioneer FX-H700BT). Easy fix, but just annoying. Crutchfield's tech support was great and was all over it.

maestro rr gm harness for 2011 2500HD

Written By mike, Luling, LA on Friday, January 24, 2014
Crutchfield Customer Review (What's this?)
 
Ok the instructions don't come with it... so have your phone with adobe handy. Also if you have a factory amplifier, there is a modification that must be completed to the harness so that the chimes work, this would be fine as it's not that hard to do BUT there is no mention of it anywhere. I had to listen to aweful chimes for 2 weeks before I recieved a PDF file which showed the modification. Crutchfield also advised me to disconnect the "amp on" wire, stating that this function is controlled by the data cable... wrong, with that cable disconnected I got a very loud buzzing noise when the chimes were supposed to sound. I'm not knocking Crutchfield for this as they were very courteous and even called me a couple of times with different things to try unexpectedly. This is on the manufacturer, the PDF I recieved said that the modification had to be completed on all GM vehicles with a factory amplifier, you would think they would post it on the site, in the install file, or at least send it to their dealers (Crutchfield) so they could assist their customers. Once all was fixed it worked pretty good, the static and distortion in the chimes still come around sometimes but it's not as bad or as often.

1 question already asked

Can you use this harness without buying the Maestro ADS-MRR? Can you use it like a regular wire harness by just connecting the color coated wires and hooking it up to just the factory harness and aftermarket radio? Or Do you have to use the data cable, RCA cables, and the OBDII connection? [ Lil_Kirby95  Apr 16, 2014 ]
1 answer
  • One end of this harness has oem plugs but the other end has a small plug that connects to the maestro box. The radio connection s are made to a separate harness that plugs into maesto box. I don't remember if the colors from the oem plugged harness matched the radio connection colors. If so, in theory, you could cut the little plug off and wire it to radio. I personally wouldn't take the gamble. Either get the maestro or buy a different harness. Hope this helps. Good luck. [ Michael   Apr 17, 2014 ]
