Aftermarket NAV in 08 hummer, will it look right?

[hotstang46`]

Just bought an 08 hummer that doesn't have NAV. I really like some of the portable garmin's and that but I'd much rather prefer an in dash unit with dvd capabilities, etc. However, I've seen some vehicles with them that just don't look right because of color variations between the nav plastic and the dash plastic. They kinda look out of place, I'm sure you all know what I'm talking about and have seen vehicles like this. I'm just worried that the dash, which looks awesome now, will loose it's slick look and appear choppy.

Anyone have an 08 with aftermarket nav that can post up a pic or give me an impression? Or possibly know of one that has near identical color on the plastic screen surround as the stockers dash?

Thanks
