2012 Grand Cherokee, I have bass on radio turned all the way down and treble all the way up..... radio sound reflects these changes, but gps voice is still very bass and a little muffled. What do you suggest?? How do I change voices?
Try adjusting it while the nav voice is talking... a little tricky (maybe have someone do the driving while you adjust). I did this with the nav volume as suggested in another thread, it might work for the bass/treble.
