I have to totally agree with that. Aftermarket installations can be a nightmare for dealers. They don't have the schematics, have no idea how the installer did the connection, etc.
When in the field a few years ago, this was a big problem. Customers would install items by cutting and splicing, and the splicer were not tight, and all sorts of problems would arise, and many had a hard time understanding why GM would not back this under warranty.
Not saying yours was not installed correctly, since I can't see how it was installed.
I will also mention that some of the worse installations I have seen were from BestBuy and Circuit City, while the best installs were usually done by a small shop with knowledgeable technicians.
