" This kit worked like a charm! I do like to take things apart but not in cars and this only took me an hour to do.
Super easy install.

The only issue I had was trying to figure out how to get the cd player back in with the wires and box out of the way and I used a little bit of Velcro then tucked them in the back to the left. I also put the wire thru the ash tray and didn't have to drill anything just pulled out the red? plastic piece and fed the wire thru that.

I have a 2005 mazda3 sp23 w/o aux."
