Hey first time on any car related forum. I got a fantastic deal 13k for 25k miles one previous owner. I don't wanna mess with sound system to much. I have a one year old son (In a coupe lol) and most of the time can't play as loud as usual. I did want to change the display for Radio. A simple GPS touchscreen feature and I've gotten hooked on the backup cam so I need it to work well with it. Any suggestions?
