Just did this mod over the weekend in my "2011 GMC Seirra extended cab"
Couple things I noticed...
- Remote Link work fine. Lock/Unlock, remote start/stop, horn & lights on/off work fine.
- Map showing where my truck is works fine
- Oil life shows ZERO when it's not on the DIC
- Gas gauge reads full when it's not
- Fuel range reads 1221 miles
- Mp TPMS readings
- On my rear view mirror the OnStar light is red instead of green, but I'm able to use OnStar fine
I called from in the vehicle by pressing the OnStar button on my rear view mirror. I told her I just purchased this vehicle. She said congrats on purchasing my 2011 GMC Seirra extended cab. She gave me 3 months free OnStar and took about 5 minutes to connect everything.
Even though it's a 2011 VCIM with the 1 plug (from the fin on the roof) instead of two, I just looked at both VCIMs, saw which wire was plugged in to the corresponding spot on the VCIM, and everything works (except for what I mentioned above). Maybe the splitter/combiner would fix that? I'm not sure. I have the splitter/combiner but my dash it too hard to pull it out, just to try. Maybe I'll try at a later date.
On a side note, I've been wanting to do this since I bought my truck. I've been so worried to o this because of all the information I've seen about others not working etc. I finally pulled the trigger (rather quickly) and purchased one from
nick2440. Then for the next 12 hours, I regretted my decision because I kept reading more and more thinking it wouldn't work. After a bunch of PMs back and forth and speaking with another member, I was somewhat OK with going through with the purchase. Once I received it, it took about 20 minutes to install (because of my iPad mini dash), but everything worked great and I'm 100% happy with it. Thanks again
Nick!!!
