I just retrofitted the factory aux input into my 06, so I have now have my Dice Silverline Pro for sale. I just removed it, never had a single problem with it. I no longer have an ipod, so I was using the aux input option on it, but both the Aux input and Ipod input are included.
This is the item:

I have DSP, but was using it without the DSP module, so I would say that requirement in the Amazon listing is incorrect.
The item is wrapped in stick-on felt with a piece of velcro on one side, for quiet and easy installation. The configuration dip switches and the ports are still exposed.
Price is $60 including shipping, or best offer.
