Hello.....just sold my '08 LS460 and replaced it with a '12 LS460. The '08 model had a built in hard drive to store my music on, but the '12 does not have this capability. So, I would like to have a hard drive available to store music on to play in the car. I have looked at the iPod Nano, and with Bluetooth, it seems like a pretty good option. Any other devices out there working better for people? In addition to connecting it via Bluetooth, it can also be connected by USB. I am curious if when connected via USB in the car if it also charges? Any suggestions appreciated. Oh, not looking to spend and arm and a leg for this. Nano runs around $150, so that is pretty much what I'm looking to spend, or less. Thanks....
