I got a Griffin Roadtrip with Smartscan (
http://www.griffintechnology.com/products/roadtrip) for my birthday yesterday. So far, it seems to be a good match for the Crossfire. All I did was plug it in, performed the SmartScan search function, tuned my radio to the displayed frequency, and listened to clear, uninterrupted broadcast. I am extremely picky about this, so I am hard to please; however, this seems to me to be a good solution to our iPod remedy and the stock head unit. It also doesn't look bad either. I will have pictures up soon.
