Crux SWRGM-49 Radio Replacement Module for 2006-13 GM LAN 29-Bit Vehicles

Finally!!! I previously had bought a new head unit and bought the pac rp5gm31 harness. After many headaches with the pac harness and NEVER being able to get it to not shut my head unit down I bought this harness. This harness works great and retains everything I need. No more head unit shutting down. FINALLY!

Perfect, Easy Installation, WORKS WELL!

I had a Axxis adapter and it caused my 08 Silverado 2500HD t throw codes, fail to start and generally caused a Pain In The A--.

I purchased this, soldered up the connections according to the directions, installed the unit and that was all there was to it

The keys aer not probrammable as on the Axxis but that one did not work, this one did.

Works Perfectly, All in all, I could not be more pleased!
