First off this worked perfect for me, sounds just like having an actually aux input. The one question i have is right now if my mp3 player is not playing a song, it is not grounding out the connection and there is some hissing, but as soon as a song gets ready to play it goes away. My question is if i could have the ground wire also go to the satellite box as well as the ground on the cut wire.

@Warhawke08 You could always wire one up, but I don't think it would have much effect on the hissing (especially if it goes away when you click "play"). Mine hisses as well when my MP3 player is not plugged in, so I think it is just related to that. If a song isn't playing, I usually just turn the radio off. Sorry I can't be of more help. If you do find a solution, let me know and I'll add it to the video description!

Can't seem to get mine working. I got a 2006 jetta with sat button. Does that sat need to be on a certain station?

[yamiyanazz]

@defnorby15 Nope, it should work just fine. Did you leave all the other cables plugged into the satellite receiver? I've been told that if the receiver isn't plugged into the antenna, it will disable the audio.

The other idea I have is that you soldered the wrong side of the wires (should be soldered to the direction that goes to the radio, not the receiver in the trunk). I'm very curious to find out why yours doesn't work. Lets debug this a little further.

I have a similar setup, but haven't used any adaptors or power splitters and I get some hissing, especially at quiet parts of songs and mostly due to the fact I have to turn the stereo up higher than 50%, would using the molex adaptor limit the hissing?

[yamiyanazz]

@stychos9 Hey, to answer your question - a molex connector will have no positive effect on sound quality. It was mostly there for ease of installation and so I could (in theory) swap the satellite radio back in (but I never use it, hence the 'theory'). My thoughts are you either have a poor quality audio cable or the solder job wasn't very clean. What gain are you running your ipod/mp3 player at? I have the ipod set to about 90-95% and that usually sounds pretty good.

@yamiyanazz I was able to finally hook this up last night and it worked like a charm!

Inside my RCA cable was three wires: red, white, yellow

Here is how they matched up:

RCA -> SAT

yellow -> blue (ground)

white -> purple/green (left)

red -> purple/white (right)

Any tips on removing the call 1-888-SIRIUS from the actual radio display lol??

Instead of a molex connector, I stripped the wires and used a electrical twist cap to avoid soldering. I bought 20 feet cable at Radio Shack and had to tuck an extra 5 feet under the glove compartment. Once again, thanks for the color details! it helped a lot !! Thank you again for this video.

@yamiyanazz I may try it later, that way the mp3 and the satellite radio have a common ground, but besides that it is working great. I'll let you know if i wire it up

[Warhawke08]

does this void the warranty on my satellite unit? (jk)

[Warhawke08]

this is amazing...

@wjcunninghamjr. I have a 2006 vw jetta and it has the "Package 2" in it. I noticed in this video that this jetta has a dual power seats unlike mine i have only a power drivers seat but i do have wood trim and real leather seats. i wonder if i have package 1 or 2? anyways...i still like my car!

Question: my '06 GTI has the SAT radio under the passenger seat. I tested continuity on the purple wires coming out of the SAT unit to the wires coming into the back of the stereo (the blue harness), and got a positive connection. So, I spliced in there, behind the radio to the correct the wires to a shorter (3 foot) RCA/3.5mm cable.... AND, when I select SAT radio, "no satellite radio" displays on the headunit... frustrating to say the least. GREAT VIDEO BTW- I know this can work!!
