I have a GARMIN 496 with the XM radio GXM30A antennae. The Garmin website has a USB data cable which says "Does not provide wiring for external power.". This is directly below the GXM30 USB replacement cable. I'm presuming all USB cables are not created equal?
Since I didn't label all the USB cables when they came through the front door, how interchangable are these? How do I tell a USB data cable from the powered cable?
