Ok, first off the title might sound a little bit more weird. I was having a hard time creating a title. 
Anyways, this is for those who don't have an aux input in their car. me and my buddy installed an aux input mount over the weekend and i'm pretty satisfied with how it turned out. My car stereo didn't have an input, but it did have the rca connection in the back. i did some research and give credit to this guy for teaching me how to do the install. its not too difficult to do.

after that was done, i hooked up my phone and everything worked great. it wasn't til i had my gf give me a call to see if i would hear her thru the car speakers when i realized that i could use this as a handsfree system kinda like when cars have the built in bluetooth. so i went to bestbuy and got a monster sonitalk microphone adapter. the great thing about this is that it has the button on the mic so you can play/pause your music, answer/end calls, and hold on the button for voice controls (3gs)! overall the quality of sound with the phone calls isn't bad. the only thing is that the person on the other end does hear an echo when they talk. here are some pics, sorry for the night time shots. lol.
Aux input:
With mic adapter
