I have a Prodigy also. Mine is at 6.1 with my Sienna. If the boost is on, will that cause difficulty in backing up?
I started to have a problem with backing up and called customer support. I was told to take the boost off temporarily andt then try reverse. However, by the time I got that info, the "Suite Escape" was already unhooked and stored so I won't be able to try that until this coming week-end when she is going (along with the rest of us) to a spot on the Russian River inland from the Pacific by about four miles. Hopefully, that will solve the problem.
