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.

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

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).
