I will definitely give it a shot.

I'm asking you to connect it directly to the battery to diagnose your problem.. I'm just trying to eliminate possible issues. If there is no problem with the direct battery hookup then we know that the BMW GPS connector could be causing some weird electrical problem. If you experience the same non-charging state from direct to battery, then we can blame the USB charger.
If it's the USB charger I'll send you a new one, even if you hacked it up.
