I would love to put a tape deck in the Av, since I have some things on cassetts that I would ?like to enjoy, and some books on tape- plus that slot above the little CD storage area is rather useless anyway, and I noticed that the Silverado has a tape deck option that fits right in that area - and this is in conjunction with the exact same head unit as we have - anyone try this out? Is it a plug and play situation? aside from the tape deck unit, any other Silverado parts needed?
