Our take on the Pioneer CDX-FM673

Pioneer built the FM modulator into thechassis of the 6-disc CDX-FM673 so that you wouldn't need to find a place in your vehicle to hide a "black box." With 12 modulation frequencies, you'll have no problem locking on to a clear channel. Source level adjustment lets you match CD level to that of your FM radio.

Pioneer built the FM modulator into the chassis of the 6-disc CDX-FM673 so that you wouldn't need to find a place in your vehicle to hide a "black box." With 12 modulation frequencies, you'll have no problem locking on to a clear channel. Source level adjustment lets you match CD level to that of your FM radio.

You control all CD changes with the wired remote/display unit. Since you can mount Pioneer CD changers at any angle from 0 to 90 degrees, installation is easier. And that makes the job more fun!

Antenna adapters might be required — if you haven't already done so, please enter your vehicle information (click on "What Fits My Car?" above) and we'll include them free with your order (if needed).
