Fred,
To fix the left saddlebag on your 06 should be fairly easy. All you have to do is move the lime green cable holder back one notch where it is clamped on the release assy inside the trunk. Remove the screws holding the rear black panel in the trunk to expose the release mechanism. You can see the lime green (yellow?) cable stop holder at the right side of this photo. Move it so it is seated in the middle notch. You may have to pull somewhat hard to get it to pop out of the U shaped cut out in the metal bracket, but it will come out.
For some reason, in 05 and 06 they started seating this cable on the forward most notch in the lime green cable stop. It should be in the middle notch. This takes up the slack in the cable.
I don't yet know when the updates will be done, but yes you will be able to purchase just the update separately.
