I have a recently purchased 9500ix, and I use this in two vehicles. I have no problems with the mount in one vehicle (pickup truck).
However, when I use it in my Evo, it vibrates over every bump, and rattles as well. I have adjusted the mount up, down, and every way it can be adjusted. It still rattes. The Evo does have a very firm ride, but my 8500 did not do this. Is this common for vehicles with firm suspensions? Is there any way I can modify my mount to make the RD more secure, with less movement?
