Query: Works Fantastic!

My 2003 Jeep did not have the little plug in for my MP3 player and I was considering having my dash removed and a new stereo installed. I am so glad that I didn't. I was skeptical at first before ordering this, but I am thrilled to discover that it works like a charm! Once I realized that I had to have the stereo button turned on, it was smooth sailing from that point on. The sound is fantastic because it comes out of my car stereo speakers and it's wonderful! Now I can use my MP3 player and listen to thousands of songs! Order it, you won't be sorry.
