I just bought a XM snap radio to switch between my EB and pontoon. My pontoon has an AUX in so no problems there. In the EB the built in wireless FM modulator from the XM radio sucks so I installed a scocshe wired FM modulator. Its the type that has a powered switch to isolate the two antennas. Not running it has great reception but I get alot of humming/whining from the engine running. I'm told I need a ground loop isolator. I know what they are but what type and brand is the best? I think I need the RCA type because the modulator has the RCA's. Any help? Thanks.
