As much as I hate the thought of going to the dealership (even though our local one is a good one as dealers go)....

I am wondering whether it would be worth an hour of labor to have them use their fancy machine to diagnose my cruise problems. Has anyone ever done this? If so, how comprehensive are the results? While part of me wants to resolder the amp and see what happens, there's another part that things I should get a dealer diagnosis on this. From everything I've read, it take their proprietary tool to find out everything that's going on with the cruise system.

Thoughts?
