iDatalink meets Chrysler

iDatalink's HRN-RR-CH2 interface harness allows you to connect a new car stereo in select 2004-10 Chrysler, Dodge, and Jeep vehicles, working in conjunction with iDatalink's Maestro ADS-MRR module. Once connected, you'll retain the use of your steering wheel audio controls and your factory amp in these vehicles.

The package includes connectors that plug in between the Maestro module, your Chrysler 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.

Keeping your factory features with an iDatalink-ready car stereo

If you're buying a compatible iDatalink-ready car stereo, you'll enjoy the outstanding performance of your receiver, plus seamless touchscreen control over most of the factory features in select Chrysler-built vehicles. You'll also be able to display engine performance data and other vehicle info on your receiver's screen.

Installation note: The HRN-RR-CH2 harness must be used with the iDatalink Maestro ADS-MRR module to connect a new car stereo to your Chrysler-made vehicle.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

iDatalink HRN-RR-CH2

Crutchfield Customer Review (What's this?)

The actual wiring is only laborious, but the instructions for doing so are ridiculously inadequate! The harness is not model specific, and none of the instructions compensate adequately for that. Some wires go to the radio itself, and not to the radio's harness, and nothing really explains that. This should be a very simple process, but it is not! The instructions are very poorly written and illustrated. In the end it all seems to work, but you won't have much fun getting to that point! I have a lot of experience wiring up electronics (I am a ham radio operator), but this confused me a lot.

Wiring harness was great the data link is a huge pain if your computer does not have the right programs you will spend all day trying to get this going I just forked out more money and took it to a place that installed radios and had them program it

Cons:

Versatile harness

MEB from Sunnyside, WA on 8/26/2016

2007 Dodge Charger
Crutchfield Customer Review (What's this?)

This harness system covers all the bases. Convenient and unique individual couplings make it good proof. Clear and colored wiring schematics were easy to follow considering how many routing and connections in my vehicle/stereo/Maestro configuration.

Pros: Clear and easy to follow schematics.

Cons: Whether to connect two couplings or leave disconnected was unclear based on existing OEM amp or new aftermarket amp. Worked it out with excellent technical support over phone. Simple solution not explained in installation instructions.

Works as avertised

Works great. Bit confusing but it working great.

Pros: Works Wires are pre cut and striped

Cons: Not much instruction. Would be nice to know more.

Quick N Easy

Quick and easy to use.

Pros: Easy to install and use. Keeps all features it says it will.

Cons: Different wiring diagrams with Crutchfield then provided after product is flashed are confusing.

Excellent... worth every penny

Lost my Fader!

EricJK from Battle Ground, WA on 12/13/2015

2007 Dodge Caliber
Crutchfield Customer Review (What's this?)

I lost the fader controls on my Caliber with the factory Boston Acoustics sound system. Tech Support tells me that this is not the case with all radios, however, that information isn't readily available on the Crutchfield website. If I'd known that, I probably would have stayed with the less expensive interfaces.

Pros: Easy to set up. Easy to wire up. Steering wheel controls work great. Ability to select what the steering wheel buttons do is a huge plus - I prefer this to having to search for the right button on the face of the factory head unit.

Cons: Fader controls only available with certain head units. Ask Tech Support before you order!

idatalink doesn't deliver.

Postman from Florida on 6/21/2015

2007 Jeep Grand Cherokee
Crutchfield Customer Review (What's this?)

Chose the IDatalink Maestro because it promised the most when paired with my Pioneer AVIC-7000NEX, I was wrong. Per IDatalink's own latest manual for my Grand Cherokee SRT8 "retains steering wheel controls, Uconnect, Uconnect Bluetooth, and more!". More? Do tell because all I got was the steering wheel controls, nothing else. The install instructions were outdated "latest from their website" and I later found I didn't need to hook up one supplied cable or splice in the OBD2 connections.. Two stars for keeping steering wheel controls and factory amp (which I don't need). Also since it was their harness they could've supplied backup cam and gps adapters. Please note Crutchfield isn't responsible for these issues and they did throw in the IDatalink and harness at quite a discount with the head unit.

Pros: retains steering wheel controls, and factory amp.

Cons: Overpriced, doesn't deliver as promised, bulky with harnesses.

no issues.

Crutchfield Customer Review (What's this?)

I took this to a shop to install in my 2007 Chrysler 300C. It was used on the Kenwood DDX8901hd head unit. no issues at all.

Pros: works flawlessly

Cons: none

Almost works

Ken C from Lunenburg, MA on 10/23/2014

2007 Jeep Grand Cherokee
Crutchfield Customer Review (What's this?)

Cable makes install a breeze, but it is not without it's limits. First of all, if you connect it as instructed you will lose GPS audio. To fix this you have to reverse the speaker connections (front to back and back to front - or white to black and black to white). That will route your front speaker output to the rear input which is the only input used. Another problem is the pinout on one of the connectors was wrong, so if odbii functions won't work, you likely have a cable that is misconfigured like mine was... You need to move a couple pins around to make it work (tech support helped with this, but after I spent hours trying to figure out why it wouldn't work). The cable does not cover the rear camera, so you have to do that yourself. It is simple to do, so it would have been a nice addition to the cable (pins 1 and 2 of the vehicle c3 connector have to feed a male rca jack, this cable only covers c1 and c2). It was quicker than hard wiring everything from scratch, but could have been better with very little extra effort from the mfg.

Pros: Easy hookup, minimizes wiring, keeps factory harness intact

Cons: Unclear instructions in some cases. Defective pinout. Requires soldering of wires you don't need (rear speaker output isn't actually used... It only takes 1 set of inputs and fades digitally, so the inputs have to be front to get GPS audio).
