Which remote is the better of the two for controlling the D3? I'm well aware that the nav controls don't work for the D3 using the SR-11. Which one works better, generally speaking, in terms of reception and functions?

i believe its the sr-11 even tho no nav functions but i dont have the 100

I have the SR11 on my D2 and works great. Why it won't work for the D3 is another one of those mysteries. At times though, if the remote sensor on the head unit is in direct sunlight, the signal is weak, but well worth having. So that may be something to consider regardless of what remote you end up with. Good luck.

Does the SR11 control any functions of the D3 (i.e. volume, presets,....)? Also, is it an infrared remote, meaning direct line to the HU when attached to the steering wheel. I have an 2007 Tundra and the steering wheel is quite a distance from the HU location. Anybody think this will work for me, with the remote on the passenger most side of the steering wheel?
