I have searched the forums to no avail. I need a car dock that will do the following: 1. Charge my phone using a cigarette lighter 2. Adjustable to any size so I can use it in my Agent 18 Case 3. Have a line out input so I can connect an aux/cassette tape 3.5mm headphone jack cable. I don't want to have to be plugging it in to my iphone headphone jack every time. I just want to drop it in the dock. I also want to make sure the audio from an interrupting phone call comes out through my car speakers as well. It seems like the phone mic works well enough to pick up my voice. If anyone has any suggestions, preferably cheap ones, thanks a lot.
