No, I have the BTB-200 and a by-passed D3 and everything works great.
Ditto. I have the D3 with bypass, self installed, and the BTB-200 and an i-Pod and everything works well together. Just do the install yourself. If you get the wiring harness and a dash kit from Crutchfield or somewhere like that the install is super easy. I had my D3, BTB-200, i-Pod installed, all the cabling routed and hidden and car back together inside an hour. Hell, I think I sat at the kitchen counter connecting the wiring harness to the D3, and moving the Mute wire longer than I spent in the car doing the install
