If you want to retain the factory unit, just get a FM transmitter. No matter what you do, it's going to sound like shit.
Not at all in my experience with the DII.
Sorry if I missed it, but are we talking DII here?
I got the Blitzsafe adaptor from logjamelectronics

It came with 1 set of RCA inputs.
For more inputs, I hooked up a unit that provided 2 more sets and a 3 way toggle switch to control which set you want to listen to.

Now I didn't have the iPod at that point (using a unit called Omnifi for MP3s), but my XM unit and the Omnifi sounded VERY good though the factory head unit. I also had the third set of RCAs to hook to anything else someone brought into the truck, like a portble CD player.
When I finally did get the iPod, even through the headphone port (although iPod volume had to be pretty much all the way up), it STILL sounded better than an FM modulator.
I have since seen other options that will allow you to connect to the bottom of the iPod, then into RCA inputs which I may consider getting for mine since I already have the Blitzsafe model listed above.

If I were to be doing it all over again, I would have considered this:

...but it wouldn't have given me the extra RCAs for other devices.
I have never been a big fan of FM modulators. The biggest problem I have had is finding a frequency that will work in all areas of the city without having a stronger singnal bleeding over what I was listening to.
I have seen some modulators that plug in to the antenna port on the head unit, then the factory antenna in turn plugs into the modulator. When you select the unit on, it cuts off the factory antenna, so you don't get the stronger stations bleeding over like I described above. I have never listened to a setup like this though.
Peace,
