🎵 SCOSCHE GMSRCL2 2003-2012 GM Class 2 Car Stereo Replacement Interface Control with Chime (Optimized for Class II Data System) Review

It fit perfectly, I should have bought it first but didn't realize the 2003 GMC Envoy required this type of interface harness. The other two I bought had wire connectors in the wiring harness that didn't match the car's wiring harness. And didn't start at all.

Best Buy told me there was no such thing and that they could build something similar (for around $120) that does. plugged in, but my radio and horns work fine. Plus an added bonus: I saved over $100 by NOT shopping at Best Buy!

What can I say, the buzzer is not loud at all, almost inaudible without the radio, the main problem is the contacts for the plugs to the factory wiring harness are complete wrong, fuses kept blowing, radio wouldn't turn on, had to disassemble the wiring harness and attach it to my truck, not worth the headache, will be replaced with a better one

Yes it restored the rap power to the stereo so it doesn't restart every time you crank the starter. The backlight didn't seem to work on my Kenwood, but that might just be an issue of its own. Dinger/bell/chime or something loud like F### even after I wrap it in sonic foam. Wrap it in foam or fill it with glue or something. Nice that the call works at least. For a data block, this is the cheapest you can get if you don't need all that crap on a star and just need to turn it on. Function and…

Works well. I have a radio and my bell in my car. A note: on older cars (I have a 2004 Chevy Silverado) the wires are not the same color as the factory harnesses. It was very confusing for a beginner like me, but they line up correctly even if they are different colors. Both schematics can be found online if you're willing to work hard, but you really don't have to. It works the way it is. This information is very hard to find, so I'm sharing it here. Using a kit without a black box also works,
