Query: Magellan has no support!

I have the explorist 600. Using this GPS in the field is a pleasure. Uploading the detail maps are a total pain. Not intuitive at all. My major complaint is the proprietary usb/charging cord has been unavailable for over two months! Magellan support has no clue as to when the cord will again be available. Therefore I cannot charge the battery and cannot use the gps. I will never buy their products again.
