Hey everyone, just thought I'd post some info on this awesome head unit I just purchased. I wanted a cheap/good unit that would work with the droid so I started researching. I didn't really care about blue tooth, but wanted to be able to either connect via usb or aux port. Luckily I found a great Kenwood receiver that does both. Here is the link to the Kenwood KDC-MP345U.
I'm able to either mount my SD card and use the USB port (It shows the Artist/Album/Song/etc.) or just plug into the aux port. I use the OEM car dock with this set up as well. This is nothing fancy, I just know whenever I was first looking for a replacement stereo, I searched the forum and thought somebody else may do the same! Now if only the Kenwood could "push" me 2.1
