If money was the same which one? A3 or Q5W
I'm down to these two 80gb models. From what I have read I believe that the A3 has better video and sound but on the other hand the Q5W just has so many xtras with it (wireless remote, bluetooth, WIFI and NAV) most I probably would bever use but again the prices are just about $100 within each other which is driving me nuts.
Also I see that the Q5W has a FM out so your radio can be tuned into the unit to receive the sound. So it probably would work on my motorcycle stereo system........
