LOL, i am not even sure what a radio replacement interface is...sorry. I can't find my receipt in the house. I am hoping it is in my car. But if you go on Crutchfield.com and look at the Sony XNV-660BT, you should be able to see what you need there. Hope this helps. If I find my receipt I will post the numbers.
hey, I like the indash double din set up you had in your mustang...what other parts needed for me to install double din like yours? besides the metra dash? any particular wires i need to purchase? Oh and by the way, I also have a mustang v6 base..thanks
