Getting ready to install an Alpine INE-S920HD and trying to figure out mounting location for the sat radio and gps antenna. I'm thinking about putting them on top of the soundbar, not in the corners like the factory antenna is located, but more in the open in the middle able to be seen when the freedom panels are removed from the vehicle. Anyone else done this and see or have had any issues.

 

That's where i ran my xm antena ran it beside the sound by and have had not issues with reception running either top. I place my gps one right under the too cover with the compass.
