I've never done any car audio installation myself before today, never took apart a dash etc. With the tutorials on here I Installed this today in less than 10 minutes. The only trouble I had was getting the male plug from the adaptor to "snap" into place. I kept pushing hard and without being able to see back there I thought I might be trying a wrong hole etc. Eventually I heard it finally click and happily put the console back together to test it out.
Works like a breeze. Tried the "loudness" eq on my iPod and it made everything sound like total ass. I switched back to no eq which is probably the best bet in any situation. EQ'ing on the iPod and then on the factory deck is way too much messing around with frequencies and turns the sound into mud. It's plenty loud for me with my iPod volume at 80% and my factory deck up close to max, and I usually play my music very loud on a regular basis.
Would highly recommend this for ease of installation, sound quality, and last but not least... cost.
