its possible, but you cant use those Y splitter cables people use to connect two headphones from 1 player. you'll have to connect it like a mixer to a switch. i made one up for my car, i can use the aux near the DSC and be able to switch over to a dedicated cable that will be for my iphone and works perfect. i'm actually making one for a buddy of mine too for his 7

 

I've also done an aux retrofit on my car. When I removed my trim I didn't have pins holding down the trim. I had some plastics that pinched metal nails. Maybe it was because I had the aluminum trim. Anyways I would definitely refer people to roskinc. Even though I haven't met him I've used his youtube video and the quality is clear and right on point.

 

thanks for the feedback on my videos....keep a look out, i just got my spare headlight i ordered and will be doing a DIY orion install, black out and when i get my spare LCI tail, i will be doing a retrofit lci tails diy and attempt the blackout mod as well on the LCI tails!

 

Just installed and coded my aux thanks to roskinc! Quality of cable is fantastic no distortion or buzzing, sounds just like a CD! Thanks again bro!!

 

Got my AUX installed from roskinc last week, thanks again man! Very cool dude and it took less than 2 minutes.

I definitely recommend anyone in SoCal to go to him if you need to get an AUX or programming to be done.

 

Just ordered roskinc's cable off ebay!

Its all installed. anybody in the vancouver area want to help me code it? or know of a place besides the dealer?

 

Bought his cord and installed it easily, now just trying to program myself. Thank roskinc for the cord and easy install video

 

Just bought roskinc's cable on ebay; looking forward to getting this done. Anyone near Raleigh that would be willing to code this for me?

 

Im here at glendora mercedes & bmw services inc., i installed the aux wire & getting the system programmed. The tech phillip pham was able to get the aux option to appear but all audio & sound is lost. The cd/radio/fm/am is out. Any ideas?

 

Did you add the AUX option to the vehicle order?

If so, then you might need to code the car to the new VO.
