Before spending a nickle, I would clean your connections. The majority of the problems you are describing are common. I would remove your rear seat an clean AND protect (dielectric grease) the two QDs under there, the front speaker QDs are under the left side of the stingray, and the main radio harness under the radio pod.
Sounds like a pain, but it may save you a trip.....

Before a trip to the dealer I would check and clean the connections from the stingray. It is easy to do but require removal of the fairing sides and center console.

BEAT ME TO IT!
