I went with a Android 8.0 unit from xtrons about 6 months ago in my Non-DSP '06 3.0 and am happy with it. Installation was a bit of a bear running a thick cable of wires from the back to the front, but worth it in the end. I changed only the head unit - plug an play with the long, additional harness required for cars with NAV, although have since replaced a couple of rear speakers that appeared blown.
