XM External Input

XM External Input
I have the standard Monsoon CD head unit and also am running the XM radio. I currently use the RF modulator, but I keep having to switch stations as I drive due to interference. Has anyone here been successful in wiring an external jack to hardwire an accessory line a XM or iPod?

Unfortunately, the 1998 Monsoon CD Headunit cannot control the factory external CD-Changer, otherwise you can convert that port toi RCA-IN using a GM9-AUX like I did on my 2001.

I missed that it was a 98. Since you can't use the CD changer port adapters on a 98 CD head unit, the simplest and least expensive alternative is to replace the wireless FM modulator with a wired one. They install inline in the antenna lead and connect to the audio/headphone port on the satellite radio tuner. The advantage is that they electronically disconnect the head unit from the AM/FM antenna when the satellite radio is in use (and reconnect it when the satellite radio is off). That eliminates all the interference from broadcast stations in the area. And, because it is a direct connection into the antenna, it also eliminates the fading that is common with wireless modulators. Sound quality will be equivalent to that of a strong local FM station so it's not the same as CD but it's quite good and pretty inexpensive.

Sounds like great advice! This will be my next task. Thanks for all of the replys.

Only headunits that could control the factory CD-Changer will work with the GM9-AUX:
1998-2002 Cassette
mid99-2002 CD (best bet is 2001-2002 CD since they supposedly can handle two AUX devices and no one knows exactly when in mid99 the change for the CD headunit to control the CD Changer happened-- the only way to tell in the mid99 is to disassemble it and check the P/N stamped on the CD player's circuit board)
