@DallasGV: I haven't contacted the seller yet. I want to look at the back of the stereo to look if it really has that 8-10 pin plug before I contact the seller. I have the regular stereo so I don't know how to switch it to Aux even if it works so we'll see.

@ECS Tuning: Thanks for the reply, I saw that on your site but I don't know if it would apply to my car since it was built in 2001.

@Miniz guy: yeah I don't know how it'll work. I guess i'll find out.

Anyone know if the stereo on pre 02 built E53 has the 8-10 pin input? Will save me from removing the radio.
