I'm Awesome
This is the way I went with mine and I am happy with it, I am one of those people that prefer the factory radio.If you want the best of both worlds, there are people who upgrade the factory CD units to include Bluetooth functions. You may be able to find them cheaper, this is just the first example I found on eBay.

There's also the RetroSound Newport, which has no CD player but sports a lot of other cool modern options like Bluetooth and amplifier pre-outs. It uses the entire opening in the dash and is a pretty decent match to the rest of the instruments.
