I have had mine installed since September and the reception is the same as stock. Since removing my roof rails, I think it looks even better. Great customer support from the Virtual Garage guys out in BC too.arloman said:I also ordered the "Shark Fin" cover for my 2010 Terrain. If you contact them by email, they will come up with a color match. Only took about a week after contacting them with color code. Perfect color match, great fit, seems to be same FM distance, and looks much better.
