Please Help! 2005 ML55
I have an '05 special edition too and bought the above product. Good luck trying to make it work. I just bought mine, set it up 4234223 different ways and it still doesn't work.
If you do get someone from Enfig to install it or run you through it, then it's definitely worth it. Long story short, this is what you want when it comes to an AUX port. And no, I don't believe there is an easier way.
Here is a write up I did on how simple it is
