Well, I think I've given up on my old Zumo 550 for motorcycle use but will still use it in the car I imagine.

The motorcycle mount broke internally/electrically somehow. It's gotten to be a pain to update anyway so I just ordered the new Zumo 595 LM.

Will be looking for the easiest way to tie it into the Sena headsets, one or both of our phones and perhaps the bike radio. Already have a Sena SM10 bluetooth transmitter which works great. Will just need to decide how to tie them all together when the new GPS gets here.

Any insights would be great appreciated.
