I'm thinking about getting the DEH-P6000UB for my wife's car. Her iPod is only a 4G so it can't directly control it. Rather than using the CD-IB100II, I was thinking about losing the iPod entirely and just using a portable hard drive. I know this should work, but when browsing folders, can you browse by folder name? It doesn't say in the manual, and when displaying titles it displays folders by number.
