What's the best system for adding the iPod to the 2005 Prius? I have the 6 disc changer but not the navigation option. I've been considering the DICE Silverline Pro adapter but also came across this one: SoundGate TOYPD2 1998-2010 Toyota/Scion-to-iPOD® Interface logjamelectronics.com/soundtoypod.html The DICE one is here: tinyurl.com/yzk5l7k Anyone have opinions/reviews/experience on these? Not sure which to get and they're pretty much the same price $144. Thanks! *SORRY IT WON'T LET ME POST FULL LINKS YET...
