Is there an auxiliary jack that I can plug my phone into on the back of my poineer supertuner 3 cd player

You hook up a aux cable from the head phone jack of the mac min in the back to the head phone jack in the Bose cd player in the back aswell

3 5mm AUX AUXILIARY CORD Male to Male Stereo Audio Cable for PC iPod...

It's not the connections it's the phone. Newer phones will allow the phone to charge but will not connect audio through USB connection because they want you to connect through Bluetooth or auxiliary plug.

Its behind the DMC1 master unit, there you'll find 2RCA Jacks for CD and 2 RCA jacks for AUX Input

it could be one of 3 spots on your deck
1 bottom right look for a rca head phone jack
2 top right look for a usb connector
3 back of deck look for rca leads

Most new model in-dash stereos have an auxiliary mini jack input. Connect a mini-jack cable to the auxiliary jack on your in-dash stereo (available at RadioShack or anywhere there are portable music player/smart phone accessories), and connect the other end to the headphone input on your iPhone/smartphone or player.

Change your stereo input to "aux" or "auxiliary" and Voila! Music will play from your car speakers.

Hi,

An auxiliary input allows you to select an external source and play it through the cd player's amplifier. It's often used for iPods and MP-3 players. Typically you just need an inexpensive patch cable that connects the headphone output from your portable player to the input on the CD player. After that you can select "AUX" as another source like CD or Tuner, and whatever's playing on the portable unit will be heard through the speakers.
Auxiliary inputs can be on the front or the rear of the CD player. Front aux inputs are typically 3.5mm stereo plugs, similar to a small headphone jack. Rear aux inputs can be RCA jacks or a 3.5mm jack. If you have a CD player with a rear aux input, a cable needs to be connected at the time of installation. Then the other end can be routed to whatever location in the vehicle you want to keep your portable player while you're using it with the CD player.
Front aux jacks are more convenient for quick connecting/disconnecting the portable player, but they tend to wear out over time.
Let us know if you have somethin more to ask else accept the suggestion.
Thank You for contacting Fixya

From memory I believe you can, it should have the 2 connecting jacks and speaker jacks in the back, let me know how you go. Good luck

you have a stereo rca plug set to a mono audio plug.
you need a stereo rca plug set to a stereo audio plug

first of all the rca jacks in the back of your radio are for plugging in an amp, not your mp3 player. there should be an auxiliary jack(looks like a headphones jack) in the front of the head unit. if there is no auxiliary jack in the front then you will have to go buy a new head unit with an auxiliary jack.

You need to identify the four wires that carry the DVD audio in the factory plug, and re-wire them to RCA plugs that can be used with the Auxiliary input RCA jacks on your Pioneer unit. The four wires should be: Left (+) light green Left (-) white Right (+) red Right (-) black The easiest way is to purchase some inexpensive RCA cables (or better yet, speaker wire with RCA ends). Cut the cables and wire the center pin conductor wires to the (+) audio wires in the stock plugs, and connect the outer shield conductors to the (-) wires. Then connect the RCA plugs to your head unit's auxiliary input jacks.
