I have a question that I hope someone here can help me with. When using a factory GM 2 wire XM antenna (green and yellow) and plugging this into a Pioneer 920xm module, which is a single plug (pink). I plug in the yellow connector which is the satellite reception it should work right? What about the terrestrial antenna plug (green), will I loose XM in cities with tall buildings?

My other question is has anyone ever tried to splice the 2 wires from the factory antenna together and then solder these to the antenna wire that plugs into the module? In theory it should work since the module will be reading terrestrial and satellite but does the module read terrestrial? I know I can solder the XM antenna and get it to work since I have fixed them before when cut.

They used to make 2-1 adaptors, check around the web. All early XM tuners had 2 plugs, only in the last 2-3 years did they switch to one

Those splitters are for single lead antenna's that output dual leads. I am talking about a dual lead antenna to a single lead output. Does it not matter anymore to have terrestrial hooked up? I think you'd lose XM in citys with tall buildings.

They make both. There were still lots of people with two lead antennas stuck to their roof that had to switch to one pole receivers, so they made an adaptor

And yes, its important to receive terrestrial antennas too

link to said adaptor please?? i have a dual lead oem antenna want to connect to the avic xm receiver!
