I posted here several months inquiring about this, and didn't get a lot of feedback, so I thought I'd try again. Does anyone know of a device that will hook into the OEM head unit and provide a usb interface for use with a flash drivve? I think GROM makes one, but all it does is just emulate the CD changer. I'm looking for something that can navigate the folder structure on the flash drive via oem radio screen. You would think something like this would be a popular aftermarket item. The AUX adapter in my TSX is nice, but I always have to unplug my ipod and take it with me when I leave. I just want something that I can leave in my car and that has all my music, and that integrates into the OEM head unit. Any thoughts?
