Alright guy, relax a little.
The man was just excited that he completed a $150 project by himself, and for a couple bucks. He was also thanking the forum.
Coming from a similar backround, I have an EE degree, and I have installed quite a few car stereos, but never dealt with a navigational unit by-pass. If it weren't for this forum I wouldn't do it on my own, but it gives enough knowledge and confidence to do it myself. (Its really not that complicated, you would just never know until you researched it how easy it is) And this saves me a few, nothing wrong with that. It does take some knowlege and experience to install and bypass one of these navigation units yourself. So give a little credit.
By the way, try getting laid, it will make your life a lot easier, and a lot less stressful
