2012 GMC Yukon Denali Backup Camera Issue

Post by hajjinm »

Greetings All,

I bought the following through Crutchfield.com:
1. Alpine INE-W987HD Navigation Receiver
2. iDatalink Maestro ADS-MRR Universal Radio Replacement & SWI
3. iDatalink HRN-RR-GM2 Install Harness for select GM
4. 2012 GMC Yukon Denali with Boss Amp, Factory Navigation, and Phone icon in the steering wheel.

I kept the OEM backup camera and didn't install the Alpine one. I installed them as per the guide provided by iDatalink. I checked the connection 3-4 times and it is matching iDatalink provided diagram (except for one wire which is the yellow/black which it doesn't exist in my GM2 harness). Bottom line this what I see after the installation:

1. Backup camera is immediately triggered once I turn the engine key and I cannot switch it off.
2. Once I put the gear in reverse the camera switch off and the head unit become fine.
3. Alpine setting icon faded and I cannot access it.

What do you think is going on, what I did wrong here?

based on what you described it sounds like the reverse output of the RR is damaged. The output is just a transistorized output and and if it becomes damaged it will operate in reverse of how it's supposed to work. I would recommend contacting Crutchfield so they can swap out the RR for you.
