I purchased a Pioneer W4500NEX aftermarket stereo which I like much more than the stock unit. The only issue is that the "chime" module that the standard install came with (from Best Buy) is used for the turn signals and is very soft (it's set to the max volume the chime can do, but it's buried deep in the consol according to the installer). I also noticed that the crash warning no longer makes a sound at all (the heads up light flashes though). The installer didn't know how that was connected or where the sound even came from. Can you help me figure out how to connect up that warning signal? Is there also a louder chime module I can get? the signals are so soft I can only hear them when the car isn't moving.
