Ok, How many 300c owner out there interested in have an aux input?

I will have a 300c this weekend to test a couple different setups I have put together.

I will be utilizing both U connect and Sirius.
My hack will require at least one of these.
Stay tuned!!!!!!

Kmoney....I am dieing for an AUX input. I have every option on the C so so no matter what you use I will be able to integrate it. However I think the Sirius would be easier. I know there are people who have already done it. I don't think they are on this board though.

Kmoney, Im with Nolm! It's a great idea!! When you say utilizing what does that mean exactly? I want the Aux input for the ipod but I'm not willing to give up my uconnect and I dont have sirius on my car.

Ok I have figured out how to use the Factory radio and get an extra input off of it. To do this mod, you have to have Sat radio. You do not have to have a subscription but the module must be there. I am in the process of getting a parts list together. If your car has Sat radio. this mod will cost you about 20 bucks and take about an hour to complete. The sound quality is as good or better than the Sat radio. I was using a portable CD player. This input can be used for any audio input needed such as MP3 player, Ipod, or DVD.

I gotta know...

I'm in the process of trying to figure out if I want to upgrade to the chrysler nav or get an aftermarket. With Alpine introducing it's iPod module and Denison maybe having one that would work w/ a kenwood display, I'd be very interested in hearing what this requires. I have the Sat module w/ a subcription. The million dollar question is: Will they work together? Or does the hack negate using the radio?

Details please... I am in the process of having a unit converted for video input and would love the info... Would we be able to utilize Sat radio as well via another switch?

Part numbers are

275-249 $5.49
275-693 $2.69
274-312 $3.99

These are available at Radio shack. This require you to install a DPDT relay between the Sat module and the radio. Once done you will be able to toggle between Sat radio and Ipod. If you do not use Sat radio you don't need the switch. Just run it direct into the Radio. Place the radio in Sat mode and your all set. I am drawing up a diagram as we speak.

Yes, the Sat radio feature is actually a seperate module/antennae (sp?) kit that plugs into the stock radio or Nav unit.

Okay, next question: Who besides you would be able to do this? Installers at a custom audio shop? Or does someone have to REALLY know these things to do it?

now that is the question. You will need basic soldering skills to pull this off. Do you use your Sat radio 300touring?

I just figured this out today. I'm not sure if anyone else is doing this but I am sure that everyone will be once word gets out that it's easy to do.

Have you verified that the SAT option exists if the SAT receiver is not present? I've not unplugged my Sirius unit to test this, but I would bet that the option to select the SAT input does not exist if the stereo does not see the unit on the CAN bus. Can anyone without Sirius confirm if the SAT option exists on their stereo receiver?

Sat radio Module MUST be present for this to work.

Yes I do, I use it all the time and won't give it up, which is why I was hoping above hope that you're hack was compatible w/ using the sat. My other question about what skills someone would need was really just, "Can you make a set of instructions for my installer to do it. I'm all thumbs with a solder..."

I understand. I should have instructions soon. You will not loose you Sat radio. You will be able to toggle between Sat and Ipod or what ever. I just finished fooling around with this in my garage on my neighbors car in 20 degree weather. trust me it works.

You are the man and I will defend you to my death.

No seriously, I love you audio/electronics guys. I don't know how you do it, but I love that you do. I'll be eagerly awaiting instructions to print out and slap in my installer's hands :)

You should get a medal or something.

Here you go first draft. I'm going to bed.

Aux input Sirius radio Hack

This is for individuals who would like an aux input using there factory radio or Nav unit. You MUST have Sirius radio module installed in the vehicle. However you do Not have to be a subscriber to Sirius radio.

You will need to purchase these parts or there equivalent from Radio Shack.
Relay Catalog number 275-249
Switch Catalog number 275-693
1/8 jack Catalog number 274-312
four different colors of 18 gauge wire

This relay is a DPDT relay that uses 12 volts to energize the coils
The switch is used to toggle the relay on and off. Any on off switch can be used, but this one look the best out of what Radio shack had to offer. Find a place to mount this switch that is easy to get to while driving. You will need to drill a ¾ inch hole to mount this switch. Make sure you check for depth clearance before drilling the hole. (The place right under the ashtray is where I installed it. The jack is used to plug your IPOD into. This can be hidden or surface mounted. I prefer to surface mount it next to the switch.

Remove the radio Bezel and set to the side.
Remove the 4 screws holding the radio and unplug both the Nav antenna (if applicable) and the radio antenna.
Unplug both the large radio connector C1 and the small connector C2.
There are 3 wires to be concerned with on the C2 connector.
Pin 1 Right +
Pin 2 Signal common
Pin 6 Left +
Cut pin 1 and 6
Splice pin 2

Cut 1 piece of 18 gauge wire same color 18 inches and 1 piece10 inches solder them to the 2 legs on the switch 275-693.
The relay 275-249 has 8 legs on the bottom. 2 of the legs are on one end of the relay away from the other 6. These two are the coil legs.
Solder a 5 amp fused 18 gauge wire to the terminal opposite of the writing on the relay. This wire should be about 15 inches long.
Solder the 10 inch wire from the switch to the other side of the relay.
Locate the cigar lighter wiring between the heated seat controls. Attach the 18 inch wire to the ground side of the cigar light circuit.
Attach the fused wire from the relay to positive side of the cigar lighter.
The two legs located nearest to the coil wires that were just soldered are going to be used for the satellite receiver wiring.
Locate the side of the relay that has the specs on the side.
This will be used for the left signal.
The clean side will be used for the right signal.

Cut two pieces of 18 gauge wire in different colors about 12 inches long and solder them to the relay terminals nears to the coil wires that were soldered.
For example, Use Blue wire for the left Orange for the right.
Attach the left (blue) to the wire that was cut from pin 6 vehicle side.
Attach the Right (Orange) to the wire that was cut from Pin 1 vehicle side
Move to the next set of terminals.
These will be used to attach to the factory radio.
Cut 2 more pieces of wire 12 inches long again one blue one orange.
Solder the blue wire to the left side of the relay.
Solder the Orange wire to the left side of the relay.
Attach the blue wire to the C2 connector wire located in pin 6
Attach the Orange wire to the C2 connector wire located in pin 1

Cut 2 more pieces of wiring one blue the other orange at 18 inches.
Solder the blue wire to the left side pin on the relay.
Solder the Orange wire to the right side on the relay.
Solder the other end of the blue wire to the terminal that is farthest from the opening of the jack
Solder the other end of the orange wire to the terminal that is second farthest from the opening jack

Solder a third 18 inch wire any color to the last terminal on the jack.
Attach this wire to Pin 2 on the C2 connector that was splices earlier.
Plug C1 and C2 Connectors back into the radio.
Test the system.
With the radio on, in Sat mode, toggle switch in the off position, the sat audio should be heard. Press the toggle switch and the relay should click and the audio should change to the IPOD. Adjust volume.

Are you going to do a drawing? Just quickly following this I am lost. I am sure i could figure it out, but if you could do a diagram that would be excellent!
