I just replaced my 6 disc Bose system in my 2006 Trailblazer with a GM Nav NON-LUX unit P/N 15800000. It had the VIN cleared before I purchased it. Everything works great, except the chime is too loud. Much louder than with the original radio. I set the chime to "Normal" in the config screen, but it's still too load. A local dealer told me that I can't upgrade the factory radio and there is nothing they can do for me except put the original radio back in.
Everything I've read says the swap is plug-n-play. Can anyone suggest a solution? Any help would be greatly appreciated.
