Hello all, great forum. Been lurking for a while and now have a question. On our 2011 LE it takes (2) clicks of the volume knob to register (1) increase/decrease of the visual hash marks (actually the 1st click results in 1 hash mark increase/decrease and then 2 clicks are required for each additional hash mark change). It only takes one momentary press of the steering wheel volume control to results in one visual hash mark change. Is this normal?
