Hi,
I have a 2005 X3 and was wondering if its possible to install an aftermarket stereo in it? I was thinking of one of those dual din navigation setups. Thoughts?

Dual Din navi will not fit clean IMO even with an aftermarket bezel. I'd just go single din flip out screen.

But its absolutely possible to use an aftermarket radio in your X3

Flip out screen in a X3 would be UGLY!! just get a Garmin and mount it on the windshield or in the storage compartment where the OEM navi goes.
