how do you switch over to an aftermarket 6 disc CD changer to play through the speakers?

Post by Talcannis »



I purchased a 1990 GL1500 that has an aftermarket 6 disc Alpine CD compact disc changer in the trunk and for a while I thought it did not work but when my bike started cranking but not starting I fiddled around with it trying to figure the problem out and all of a sudden the CD player was playing through the speakers. I don't what I did and can't figure out how to do it again.
Does anyone know the trick to get the sound from the CD player to play through the speakers? What button or combination of buttons do I need to push? There are aftermarket switches that work lights and such but I've tried them all with no luck.
It looks like the original system with tape deck.

Depends on how it's wired up. Either the radio was modified to have an aux input, a cassette adapter was used, or it uses an FM modulator to play through the radio.
All of these methods were popular back in the day. You will have to snoop around to see what yours has.

BTW what is a CD? ;)

I have a similar version Alpine CD changer. It works thru the FM radio with a modulator, just tune in the programmed frequency of the modulator into the FM radio.

The modulator goes in-line with the FM antenna and inserts itself in-line in place of the antenna, so when the Alpine is powered up, any other FM reception suffers due to the antenna being cut off.

My model has a mode switch on the control unit, Push to turn on CD changer, Push again to switch from CD changer to the AUX input on the modulator, push and hold to power it off. This restores the antenna to the stock stereo. The AUX input is nice, I use it for my Sandisk MP3 Player.

Shows the Alpine FM Modulator in the Left Cubby and the control unit laying on the air cleaner cover. Aux Input jacks on the modulator.

Bike assembled. Velcro pad is where I stick the MP3 Player with AUX cable pulled out of the cubby just far enough to reach it.

So are you saying that I just have to find the exact frequency on fm? That would make a lot of sense on how I stumbled across it and couldn't find it again, LOL. Tomorrow I'll flip through this tuner until I hear start playing. Thank you for the help.

The modulator will probably indicate somewhere on it what fm frequency it is using, usually very low on the band.

It usually is in the 88.4 to 88.9 FM range.
My unit is set for the 88.7 station to operate.
