I live in a RHD country and the directions from Waze come out of the front left hand speaker - which makes perfect sense in the (majority) LHD countries, but is quite hard to hear in certain circumstances.

Either the sound should come equally out of both front speakers or it should be localised so that in LHD countries it comes out of the left speaker, and in RHD countries it comes out of the right speaker so it's closest to the driver.
