Alright, I got the 16gb SD Card and am delighted with it. Now, what would be awesome is to have a new car stereo that runs usb. Hence, charging and playing my jukebox of music. So, I went to the local stereo store and looked at some stereo's with USB connections- spoke with the guy at the counter and he said it's as simple as plug and play, works with Iphone etc. Well, I ran out got my USB cable plugged them both up and while it charges the G1- every stereo I tried would not recognize the G1 and it wouldn't play. I went to settings/applications/ and tried fiddling with the USB debugging switch all to no avail. Anyone know if it is possible to play music through USB? Help!
