Placement of Aftermarket GPS & Sirius Antennas

[mazda9]

Anyone have a recommended place for aftermarket GPS and Sirius antennas in a CX-9? Currently, I have a sirius antenna mounted in the center of the front dashboard and the GPS antenna in the area where the factory clock/thermostat display is. The sirius seems to have many dropouts, is this a sign of interference from the GPS antenna? Any suggestions on placement of the 2 antennas?

i put the aftermarket gps right next to the stock oem..gps works fine with no issues. i bought a xm radio tuner but havent installed it yet..i have read someone mounted the antenna inside the rear spoiler and gets a good signal. i am definately going to try that first, and worst case ill just run it right above it onto the roof if it doesnt work inside the spoiler.. good luck!

has anyone else found any good hiding spots for the antenna?

the nav antenna can go pretty much anywhere since the signal is stronger. the sat antenna need a "clear view" of the sky. both antennas must not be covered by metal
