No, this is NOT the problem at all. The same inability to communicate with the iPod is present with all of the iPods I own and my iPhone 5c as well. A few of my iPods are not hard drive based. Its definitely the round connector on the Boom chord (part number 72651-11 I described above).
Regarding hard drive based iPods, all they need is dampening from the vibrations of the ride. I've known this since I started using the iPod Classic in my car 3 years ago. Harley/Boom doesn't provide a solution, and can't guarantee that people will figure out a dampening solution, so they put the disclaimer or anti-recommendation in there so they don't have to support it.
The solution I've used on the motorcycle since last June was simply to put the iPod in an unused motorcycle glove before storing it in the fairing to dampen any jolts from the ride. Works great, and it virtually never loses connection, unless the jolt is very severe like a pot hole. I would expect the saddlebag iPod tether solution to dampen even better than the glove because it is suspended in air by the pocket in the tether that hangs loosely from the saddlebag lid.
The whole setup was working fine until I had to disconnect the cable, and found it wouldn't come apart, and was stuck together. As a result of struggling with it, I must have damaged it resulting in the inability to control the iPod from the head-unit/handle bars. It's the achilles heal in the whole saddlebag setup if those connectors break all the time.
The seller did not respond to my inquiry for a replacement cable. I found a new old stock cable on eBay for $90. If this doesn't work out, I might have to go back to storing in the fairing, and add a lock so I can just leave it in there.
