Looking to connect a device to your factory radio?

While many newer vehicles include an auxiliary input, many current and older vehicles do not offer this feature. Here's where the iSimple PXDX comes in. Using a vehicle-specific adapter from iSimple (not included), you connect the iSimple PXDX to the CD changer port on the back of your factory stereo. Once you reinstall the stock radio, you've now got an auxiliary input for your portable music player, DVD player, tablet, cell phone, or even a "Dock and Play" satellite radio.

A choice in connections

The package includes RCA inputs and stereo mini-jack cable connections, allowing you to connect just about any type of device. You'll enjoy better sound quality than offered by an FM modulator or most other options. Warranty: 1 year

Note: If you haven't already, please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this adapter is compatible with your vehicle and which additional cables are needed.

Installation Note: This adapter uses the changer port on your factory radio, so you won't be able to use your factory CD changer or satellite radio tuner once the adapter's installed. It will not work in vehicles with built-in 6-disc changers.

Product Highlights:

  • auxiliary input adapter for factory stereo
  • allows connection of almost any sound source to your factory radio
  • offers RCA and stereo mini-jack inputs
  • requires a vehicle-specific harness (not included)
  • warranty: 1 year
  • Our 60-day money-back guarantee

Does what it says (2000 Crown Vic)

Written by: Sly from Texas on April 24, 2015

2000 Ford Crown Victoria
Crutchfield Customer Review (What's this?)

Even though it's not recommended for the 98-2002 Crown Vic/Grand Marquis/Town Car, it can be wedged in above the radio. You have to remove the bypass section of the CD Changer adapter cable and then you'll have enough room to wedge it all in there. It's easier to just string a wire puller in from the glove box and fish the long input cable with the headphone plug out and just leave it in the glove box, but anyone could mount an AUX jack in the dash and run to the RCA jacks as well if they wanted. I agree that it's not recommended for the above listed vehicles unless you're very good at finding ways to make things fit. Took me about an hour to figure it out, remove the bypass section of the adapter cable and refit everything. Would definitely be much easier on an 03+ that will fit 2-Din instead of the 1.5 din of the 98-2002 vehicles. Sound quality is as good as your device will give it up to the quality of the stock head unit (which in a car, is usually good enough). And for my wife, everything still looks stock and there's no wires hanging out from under the dash, so it's all good, and I can listen to all my tunes from my phone or mp3 player without issue. And if you don't want to go through all the trouble I did with fitment with the radio, you can always extend the adapter cable's wires for the PXDX unit to mout it elsewhere in the car that isn't so claustrophobic. This does require wire soldering skills as I would not trust splices to hold up with those thin wires.

Pros: Plug and play for the most part (gotta wire up power and ground on some adapter cables). Manual has ALL the dip switch settings for all compatible vehicles. The manual is downloadable from so you can check compatibility before you order even if Crutchfield says it won't fit.

Cons: The device could be thinner for easier fitment.

Just OK

1997 Ford Escort
Crutchfield Customer Review (What's this?)

Installed on 97 Escort factory radio. The install is not plug and play. you have to connect this unit to power. This required cutting and splicing Pos and Neg radio power wires. afer installation it was tough to get the extra cables and wires tucked in so the radio would slide back into place. I have the premium sound system and have replaced both front and rear speakers with pioneer 3 ways. The unit works as described but the sound quality is not equal to the factory trunk mounted CD changer.It is about the same as the FM modulator I was using (minus the occasional radio static) The other issue is the imput patch cord will come unplugged from this unit easily. I used electrical tape to help secure the plug/cable into the unit since you have to remove the radio to reconnect it if it comes out. All in all I cant harldy recomend this over an RF modualtor type since I dont notice any real imprvoemnet in sound quality that I was expecting. I will keep it since I took the time to install it though. Oh yeah, one more thing. If you have the factory trunk mounted CD changer, make sure you unplug it at the trunk otherwise the volume and sound quality will be poor.

Pros: provides aux input for factory radio

Cons: input cable not very secure and will fall out, I tapped mine to help hold the connector in. sound quality is not as good as the factory CD player you have the input cord just hanging from under the dash, this unit would be alot better if it had bluetooth capabilities you have to spice into radio power wires to supply power to this

Excellent replacement for the stock CD changer

1995 Lincoln Town Car
Crutchfield Customer Review (What's this?)

I stream Pandora from my phone through my car audio. Phone calls come through car speakers crystal clear. I only wish that the PXDX had a mic input and Bluetooth with the same wired hookup to the system. Bluetooth in lieu of transit hf. That would make the PXDX hands down perfect!

Pros: Compliments stock system, wired instead of radio station input, works with anything that outputs through aux cable. Aux cable is long enough to reach the front seats of a Lincoln Town Car.

Cons: Not Bluetooth.

Factory Radio Compatibility: The iSimple PXDX Auxiliary Input interface integrates an auxiliary audio source directly into the factory radio of select vehicles, using a vehicle specific cable (sold separately). Your vehicle must be equipped with or have the ability to support an external CD changer. The iSimple PXDX provides either female stereo RCA jacks or a 6' stereo minijack cable.
  • Not compatible with radios that have a built-in 6 disc changer.
  • Not compatible with any factory external audio source such as XM tuner, CD changer, or Cassette player. These devices must be disconnected and will no longer function.

Note: The interface module's eight dip switches must be configured based on your model, make, and year vehicle. Please consult the Crutchfield Car Selector to see if your vehicle and factory radio is compatible.
