How to hookup auxiliary audio source to I/S radio?

[Rick Groseclose]

I have a '99 I/S and I want to hookup a auxiliary audio source for those long rides with ear plugs.  Any help?  I found a plug (round, about 1/2" in diameter), not sure if I just plug into that or not.  Thanks, Rick

Take a look at the I/S radio unit that is immediately under the seat. One small (4mm) wire with a capped 1/8" stereo jack at its end will be found connected to the unit. That is the stereo's "Aux" audio input. Tip and ring are the two audio channels, sleeve is ground. You can pick up the mating connectors (or entire cables) at Radio Shack.

Thanks so much.  I did get the jacks and life is good, so now I can play music off my phone.  I also put SIRIUS on and I am really loving life now.  Just bought Polk DB501 speakers for both front and back, it is time to replace them.  Also, just bought off ebay was a Sony XM-4S Xplod amp.  Should receive in three days, will let all know how it sounds then.  Ride Safe.  Rick
