angle isnt bad at all. i use the remote and point it straight up with it held in my hand at a 90 degree angle w my arm resting on the armrest. i actually just reach up alot to use the 1 to 10 presets w/o a problem.
Cool setup. I have the same exact unit but I mounted mine right under the armrest. I was thinking about mounting it there but I was concerned about operating it while driving and I was too lazy to wire it all around the headliner.
