Understood- IMO, there are quite a few double-din units that, when paired with the metra kit, look very clean and OEM. I'd suggest you look into investing in something like that.
I have the Bose without nav and I think it's really one of the worst looking things in the cabin. The lcd display is dated and displaying info (Especially from things like XM) is a pain in the ***.
Either way, best of luck with your upgrade.
