Installed brand new Z130 today but the radio signal goes in & out with the static and all as I'm traveling or stationary. will get a little clearer when I move my hand over H/U. Doing this is on HD also as most stations I listen to here in Houston are. BTW, it's in a '05 G35 and I've heard that our antenna's in rear glass could be the problem. Any ideas? Thanks in advanced! Also see my thread I posted b4 this one with issue of ipod (2) diff ones and my DroidX only playing on right side speakers.
