Thanks Baalzamon. I've tried various combinations to charge, rather than just power the 800 eg. E Werk > USB (female) > USB (male) > Mini USB > Edge800, and E Werk > Mini USB > 800 direct but both options will only provide power, not charging. From reading up on the Garmin forums I think, from memory, that it is Garmin firmware issue that may or may not be being dealt with by Garmin.
Please excuse the ignorance, but what is #8 cable?
