SUCCESS!
One of my friend with smaller hands than me got it!
I can add a little hint to your installation steps: We put a little piece of scotch tape so the cable and the connector stay at 90 degrees, easier to plug it in once inside the dash.
That's it! thanks for your offer but now I don't need to drive all the way from Quebec to DC
I didn't have a usb key and instructions neither in my box, only the mp3 player.
I'm using a Kingston Datatraveler 4gb right now, but I have some troubles.
I've been able to play a mp3, so I don't think the device is broken, but I have trouble when putting many mp3.
Any advice about the filenames, folder names, special characters (I speak french, so I have é or è in some songs, but I've tried without thoses)?
I didn't test very long, I will do more tests tomorrow morning.
I will try to get a hand on another usb drive or a sd card.
I'll let you know how it goes!
