As we all know, the gear selector locks when in Park, and you need to hit the brake to release the locking mechanism before you can shift into other gears. I've only had my '07 for a few weeks, but I never noticed a sound when the locking mechanism disengages. I had a touchscreen nav system installed yesterday (pics to follow soon), and now I hear a fairly loud mechanical sound whenever the lock disengages. Still works perfectly, though. Did they mess something up, or had it always been that way and I never noticed?
TIA
